Yeah I used to use VLC as well. It was a bit cumbersome to have to manually set up streams (through MythWeb) everytime and load VLC on the side, but it certainly didn't the job.
I was a little surprised MythStreamTV was removed as well, since the 0.21 streaming capabilities seem listed as experimental. But like most things here, I'm certain there is a solid, logical reason for that action.

Hi,
I still get picture + static for flash and picture + no sound for asx. I've still got no idea why this is not working!
To actually get the asx stream working (with picture but no sound) I used MPlayer. To do this I had to remove all authentication on MythWeb in apache by commenting out http://www.knoppmythwiki.org/index.php? ... thWebHowTo :
Code: #<Directory />
# AuthType Digest
# AuthName "MythTV"
# AuthUserFile /etc/<em class="highlight marker searchword-1">htdigest</em>
# Require valid-user
# BrowserMatch "MSIE" AuthDigestEnableQueryStringHack=On
#</Directory>
which was towards the end of the apache config file.
Then restarting the MythBox. This avoids the authentication issue with WMP and MPlayer but still does not allow WMP (version: 11.0.5721.5145) to play the asx stream at all - it hangs when connecting to the stream (after locating it) with the following message:
"Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."
I take it therefore that WMP is missing a codec to play asx streams.
MPlayer will play the stream (with no sound) however, simply download MPlayer GUI for Windows and right-click on it -> Open URL and then type in the URL to the stream on MythWeb which is the URL that your browser goes to when you click on the asx stream button.
I never got MythStream on R5F27 working with sound ( http://knoppmyth.net/phpBB2/viewtopic.p ... highlight= ) -> it was like the asx stream on MPlayer, perfect picture but no sound at all, except that it played in WMP!

I've just played around with WMP and read a bit about DVB-T codecs.
From this article:
http://www.gossamer-threads.com/lists/m ... ers/339873
I got a hint that DVB-T .mpg files are really encoded in TS (Transport Stream): MPEG-TS ( http://en.wikipedia.org/wiki/MPEG_transport_stream ) - something I was not aware of. What I understand is that there are several 'streams' multiplexed together in one file which mythtv gives the extension .mpg
In order to get back to basics and determine what WMP can actually play, I download a short clip by clicking on the direct download in MythWeb, but WMP would not play this even though I had MPEG2 codec installed (DVDs play fine for instance). Having understood that this might not be any ordinary mpg file I found a direct show codec called hdtvpump on an interesting site ( http://www.dvbportal.de/) at ( http://www.dvbportal.de/projects/hdtvpump/index.html ) and contrary to its name it will play SDTV (or EDTV as I now understand 576p is defined as: http://en.wikipedia.org/wiki/EDTV ).
So I installed this on a Windows XP machine and tried to play the downloaded .mpg file from MythWeb on my HDD. It wouldn't play and that's because this filter is only for .ts files. So following the hint on the dvbportal website I renamed the file to .ts and then in WMP clicked File -> Open -> ...file... and WMP gave a warning about not being able to play this file type (which I clicked "yes" to ignore) and then hdtvpump displayed a warning about being in ac3 mode for audio (presumably for hdtv) and said a restart was needed for MPEG audio mode. To get MPEG audio mode I clicked "properties" on the new plugin that had appeared in WMP (to display goto view -> plugins and tick "Transport Stream Controls") and then unticked "Prefer AC3 audio track" and clicked on the top audio stream in the audio stream box. The recording played fine with good picture and sound!
So at least I could actually play these files on a machine other than on MythTV in WMP (MPlayer clearly has this demuxing built in so does not require all this direct show codec installation).
To be able to play the asx stream direct from MythWeb I found a website exlaining the asx file: http://msmvps.com/blogs/chrisl/articles/17294.aspx
So I downloaded one and opened it in Notepad:
Code: <ASX version = "3.0"> <TITLE>Golden Balls</TITLE> <ENTRY> <TITLE>Golden Balls - </TITLE> <AUTHOR>MythTV - MythWeb</AUTHOR> <COPYRIGHT>GPL</COPYRIGHT> <REF HREF = "http://mythtv:80/mythweb/pl/stream/65003/1217264244" /> </ENTRY> </ASX> Whre "mythtv" is just the hostname of the box you are streaming from.
But this does not really help us because I do not know what the stream format is - only that if you paste the URL in the .asx file into MPlayer that you can view the stream with picture but no sound.
As MPlayer seems to have every codec you'll ever need I reckon the lack of sound is due to ffmpeg on the MythBox which must have trouble negotiating the mpeg-ts file and not select the correct audio (as there are several audio streams shown in hdtvpump). So I reckon that the original file dumped off the dvb-t card must have to be converted into MPEG-PS which is the other type of MPEG file that I am aware of and is apparently the one which most players are expecting to view. For the stream to work properly. This thread might help us:
http://www.gossamer-threads.com/lists/m ... vnz/332968
Let me know if you get any further with this!

This user seems to report a similar problem back in 2005 (although I don't know the distro etc.)!!!!
http://www.gossamer-threads.com/lists/m ... nd;#151550
Except this time it appears to be with playback on MythTV itself. They recommend changing the recording type from PS to TS. But I cannot find it in the settings on mythtvsetup - I think it has been removed because recording in PS mode caused some sound dropping out problems:
http://www.gossamer-threads.com/lists/m ... nd;#110279
I think that MythTV currently records DVB-T to disk in TS format by default with no obvious way to change this - hence why we need direct show filters to demux the TS file and allow us to view the downloaded file from MythWeb in WMP (see previous posting).
I reckon it is ffmpeg which is getting confused by the TS file and not demuxing properly (splitting up the audio and video properly as in link at bottom of this post) = no / static sound on stream in MythWeb. Whereas the internal player in MythTV is quite happy to deal with TS streams.
So perhaps we want to continue to allow MythTV to record DVB-T in TS mode (to ensure good sound when viewing in MythTV) and then convert to the PS file type on-the-fly when we want to stream on MythWeb so as to allow ffmpeg to read the file properly and therefore re-encode it properly. Hopefully if this following program is finished now (or an alternative avaliable) then we can use this to do the conversion:

Flash (and ASX) playback works for me. I'm not using the default ffmpeg--I needed faad (aac decoding) support for ffmpeg, so I uninstalled the default and re-installed from the debian-multimedia unstable repositories. I ended up with:
Code: FFmpeg version SVN-r13582, Copyright (c) 2000-2008 Fabrice Bellard, et al.
configuration: --prefix=/usr --libdir=${prefix}/lib --shlibdir=${prefix}/lib --bindir=${prefix}/bin --incdir=${prefix}/include/ffmpeg --enable-shared --enable-libmp3lame --enable-gpl --enable-libfaad --mandir=${prefix}/share/man --enable-libvorbis --enable-pthreads --enable-libfaac --enable-libxvid --enable-postproc --enable-libamr-nb --enable-libamr-wb --enable-x11grab --enable-libgsm --enable-libx264 --enable-liba52 --enable-libtheora --extra-cflags=-Wall -g -fPIC -DPIC --cc=ccache cc --enable-swscale --enable-libdc1394 --enable-nonfree --disable-mmx --disable-altivec --disable-stripping --enable-avfilter --enable-libdirac --disable-decoder=libdirac --enable-libschroedinger --disable-encoder=libschroedinger

That being said, I didn't get a chance to test this before I upgraded ffmpeg, so I'm not sure if that is what made the difference. I also don't see ffmpeg running while viewing a flash-encoded video?

Hi,
Thanks for that, our ffmpeg's seem to be quite a bit different - you mention libfaad, what exactly is faad because my deault (straight after installation of R5.5 ffmpeg) has libfaac?
I'm sure ffmpeg is being used to stream flash and asx because if you have a look at: /usr/share/mythtv/mythweb/modules/stream/handler.pl
then it says:
Code: # Find ffmpeg
$ffmpeg = '';
foreach my $path (split(/:/, $ENV{'PATH'}.':/usr/local/bin:/usr/bin'), '.') {
if (-e "$path/ffmpeg") {
$ffmpeg = "$path/ffmpeg";
last;
}
elsif ($^O eq 'darwin' && -e "$path/ffmpeg.app") {
$ffmpeg = "$path/ffmpeg.app";
last;
}
}
and also: Code: # Print the movie
$ffmpeg_pid = open(DATA,
"$ffmpeg -y -i ".shell_escape($filename)
.' -s '.shell_escape("${width}x$height")
.' -r 24 -f flv -ac 2 -ar 11025'
.' -ab '.shell_escape("${abitrate}k")
.' -b '.shell_escape("${vbitrate}k")
.' -acodec libmp3lame /dev/stdout 2>/tmp/ffmpeg-output.log |'
);
unless ($ffmpeg_pid) {
print header(),
"Can't do ffmpeg: $!";
exit;
}
print header(-type => 'video/x-flv');
So ffmpeg must be being used. the 'default' ffmpeg on Knoppmyth R5.5: Code: FFmpeg version SVN-r12391, Copyright (c) 2000-2008 Fabrice Bellard, et al.
configuration: --enable-libmp3lame --enable-libfaac --enable-liba52 --enable-libvorbis --enable-gpl --enable-shared --enable-libxvid --prefix=/usr --enable-libtheora --arch=i586 --cpu=i586 --enable-pthreads --enable-avfilter --enable-postproc
libavutil version: 49.6.0
libavcodec version: 51.51.0
libavformat version: 52.9.0
libavdevice version: 52.0.0
libavfilter version: 0.0.0
built on Apr 16 2008 05:24:04, gcc: 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)
FFmpeg SVN-r12391
libavutil 3212800
libavcodec 3355392
libavformat 3410176
libavdevice 3407872
I take it to uninstall ffmpeg I type: Code: apt-get remove ffmpeg
as root;
and then please could you advise as to how to install ffmpeg with all these extensions?
Thanks,
Mythman + many others who are trying to get flash +asx working with DVB-T
PS: please can I confirm that you were trying to stream DVB-T files that were dumped off your DVB-T card straight onto your hard drive?

FAAC and FAAD are the encoder and decoder respectively for aac (mp4) audio. So with just faac you can encode an audio file (or audio+video) for the ipod or other mp4-friendly device. However if you want to use ffmpeg to go the other way, e.g. convert aac to mp3, you need faad to decode the mp4 audio--that's my understanding.
WARNING!! Doing the following has the distinct possibility for ruining your software, so please make a backup first and don't expect me to be able to bail you out if it doesn't work!!:wink:
To change to the latest ffpmeg from debian-multimedia repos:
#modify 2 lines in /etc/apt/sources.list to match below (changed to "unstable"):
Code: deb http://www.debian-multimedia.org unstable main
deb-src http://www.debian-multimedia.org unstable main
Then as root, run the following: Code: apt-get update
apt-get install ffmpeg
If it errors out with unresolved dependencies for mplayer (this is what mine did) then proceed with the following: Code: apt-get remove transcode mplayer
apt-get install ffmpeg
apt-get install transcode mplayer
check ffmpeg version now: Code: ffmpeg -version
Hopefully your flash (and everything else) will now work successfully, but please IF YOU CARE ABOUT YOUR CURRENT SETUP, DO A COMPLETE BACKUP FIRST.[/code]

My videos were captured from a PVR-150, which seems to put out similar files based on previous posts.

Hey yababom that really worked!
Flash player on MythWeb now plays DVB-T recordings with sound!
Thank you very much for that it works fantastically!! 
I followed your instructions (thank you also for them) and got an error on first installing ffmpeg but it didn't seem to say anything about mplayer. Anyway I followed your advice and removed mplayer but ffmpeg still wouldn't install (came back with some error) here:

I then did apt-get install ffmpeg and it said it was the newest version.
I then installed mplayer again by apt-get install mplayer and that installed just fine.
One thing I was unsure of was the configuration file - I just accepted the default no when prompted was this the correct thing to do?
I have not had a chance to verify whether everything else (like mplayer or the asx stream)works yet but hopefully it does!
Thanks again and good luck to everyone installing flash player on R5.5!

Mythman13--You are welcome, and thanks for documenting your experiences: I'm sure others will find it useful.
My instructions were based on some rough notes that I had, but by the time I did this, I had already done a lot of tinkering with installing all the required dependencies to install ffmpeg from source, so I'm not surprised that your experiences varied from mine a bit.
Quote: One thing I was unsure of was the configuration file - I just accepted the default no when prompted was this the correct thing to do?
In my case I examined the changes and didn't see anything major so I accepted the changes--but I'm not expert enough to say if that the right thing to do in every case

Yababom - Thanks for the tips
Mythman13 - Thanks for the details.
I followed Yababom's direction, and ended following the same exact path as Mythman13. Great job to both of you. I tested MPlayer afterwards and after several minutes and testing controls, seems stable enough for me!
Flash works great now online. However, I still can't seem to get asx files working. I tried both with and without authentication, both MPlayer and WMP 11.0.5721.5230. No luck in even loading either.
But that should be ok if I have the flash working!

Now that we got flash working, does anyone know what kind of load it puts on networks? My reason for asking is I do not want to show up on the bandwidth reports at work and have my IP address blocked for streaming media rules. Sorry if this is to off topic.

No problem, thanks once again to yababom for the advice! tzoom84 wrote: However, I still can't seem to get asx files working. I tried both with and without authentication, both MPlayer and WMP 11.0.5721.5230. No luck in even loading either.
I've got asx working in MPlayer, but it is a bit of a workaround and not as simple as clicking on the link button. My setup after doing the re-installing above is: * No authentication on MythWeb at all (see previous posting on this thread) * Use MPlayer on Windows computer on local network. * Select programme recording you want to stream by right-clicking on the asx stream link and select "Save target as" or similar. * Save the .asx file to your local hard disk and open with Notepad or nano or other text editor. * Find the line <REF HREF="http://......." /> and copy the hyperlink to clipboard. * Open up MPlayer and right-click on it and select "OpenURL", paste the URL from clipboard in and click "OK" * The stream should start with good picture and audio in MPlayer I have not got WMP working yet or been able to just play the asx stream by clicking on the icon - but still working on that as I need to first find the codec of the asx stream! I don't think you can stream with authentication on MythWeb as I don't think MPlayer or WMP would have the passwords. wmcvetty wrote: does anyone know what kind of load it puts on networks
No I'm not sure what load flash streaming puts on networks, but from my own expereience it is far less than asx streaming and on a wireless network it seems to load a bit of the stream, then pause and load a bit more with not very much activity on the wireless access point light. So I'd say it is quite light on the network, but looking at the file which does the transcoding: /usr/share/mythtv/mythweb/modules/stream/handler.pl it seems that you can change the bit-rate etc. to customise for your own network settings (obviously if you watch for longer you will transfer more data):
Code: # Print the movie
$ffmpeg_pid = open(DATA,
"$ffmpeg -y -i ".shell_escape($filename)
.' -s '.shell_escape("${width}x$height")
.' -r 24 -f flv -ac 2 -ar 11025'
.' -ab '.shell_escape("${abitrate}k")
.' -b '.shell_escape("${vbitrate}k")
.' /dev/stdout 2>/dev/null |'
);
unless ($ffmpeg_pid) {
print header(),
"Can't do ffmpeg: $!";
exit;
}
print header(-type => 'video/x-flv');
my $buffer;
while (read DATA, $buffer, 262144) {
print $buffer;
}
It seems to mention variables $abitrate and $vbitrate which are set in the script as: Code: $width = 320 unless ($width && $width > 1);
$vbitrate = 256 unless ($vbitrate && $vbitrate > 1);
$abitrate = 64 unless ($abitrate && $abitrate > 1);
So have a play around and try and find out what the bit rate actually is.
One thing that I'd like to change is the buffer size as I get the video and audio stopping approximately every 6 to 7 seconds as the transcoding trys to keep up with the playing. If you decrease this number (262144) down to 1 then the stream plays but with continuous stuttering, this suggests that transcoding on my P4 machine with 1GB of RAM takes longer than real time which I guess kinda makes sense. So I increased this number up to 462144 but this makes it take longer to start the stream and it still pauses every 6 to 7 seconds with the pauses no taking proportioanlly longer! Anyone got any suggestions on how to stop the stuttering - the only work around I have is to start the playing and rewinding it back to the beginnning again!
thanks, Mythman

Looking at the MPlayer debug console for an asx stream I get the following output:
Code: Cache size set to 320 KBytes
Cache fill: 0.00% (0 bytes)
TS file format detected.
VIDEO MPEG2(pid=101) AUDIO MPA(pid=102) SUB DVB(pid=103) PROGRAM N. 1
Connecting to server
VIDEO: MPEG2 720x576 (aspect 2) 25.000 fps 15000.0 kbps (1875.0 kbyte/s)
==========================================================================
Opening video decoder: [mpegpes] MPEG 1/2 Video passthrough
VDec: vo config request - 720 x 576 (preferred colorspace: Mpeg PES)
Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
VDecoder init failed :(
Opening video decoder: [libmpeg2] MPEG 1/2 Video decoder libmpeg2-v0.4.0b
Selected video codec: [mpeg12] vfm: libmpeg2 (MPEG-1 or 2 (libmpeg2))

==========================================================================
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, s16le, 192.0 kbit/12.50% (ratio: 24000->192000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)

Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
[swscaler @ 00B28030]SwScaler: using unscaled yuv420p -> rgb32 special converter
VO: [directx] 720x576 => 768x576 BGRA
So it is a TS format mpeg2 file with mp2 audio! i.e. the original DVB-T recorded file! So I don't think it is being processed at all by ffmpeg! But I have no idea why after re-installing ffmpeg it should start playing?!
I don't think we shall be able to get WMP playing this though as WMP has problems displaying TS format mpeg files.
