Does anyone know where the script that encodes shows on the fly to FLV in mythweb is? I'm trying to troubleshoot it because the sound is just static right now. Anyone had this problem?

Yep. I have static in the left channel. If I turn it up really loudly and put on a set of headphones, I can hear the slowed down audio over the static in the right channel.

Yea, you're right. I hear the same thing now that I listen closer. Anyone have any ideas?

Post subject:  same for me with DVB-T broadcasts
Yeah I'm getting the same thing (static and *very* slowed audio in the left channel) when streaming DVB-T captured files (.mpg) over the Flash Player and the .asx stream on mythweb. Check out this thread:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=18477

Not sure why, but I also think its to do with ffmpeg not having the correct codec for DVB-T. What file format are you trying to stream?

I get it with MPEG2 captured with a PVR-250/500... which ffmpeg certainly has the codec for.

BTW - What is the trick to getting the .asx stream to work? Mine connects to the point that I see the title information for the Show, but I never get video or audio.

/usr/share/mythtv/mythweb/modules/stream/handler.pl

Approx: line 163. change output from /dev/null to something like /tmp/ffmpeg-output.log

you can verify this by trying to play the movie within the flash player, and doing a "ps -ax" on the backend. definately using ffmpeg to encode on the fly.

Now sure on the sound issue yet though.

Ive not tried this yet to see if it works, but this discussion on mythtv users seems to be talking about solving this problem:

Post subject:  can't get this to work...
Hi,

I've tried their suggestion - basically adding -acodec mp3 to the handler.pl file. This didn't work - flash player stopped working with no image when it started playing. So I changed it to a different varient: -acode libmp3lame and got exactly the same results as before!

According to apt-get libavcodec1d is already installed but I haven't tried medibuntu (not sure that this will work with knoppmyth or if needed )and ffmpeg is configured with options:

--enable-libmp3lame --enable-libfaac --enable-liba52 --enabl-libvorbis --enable-gpl --enable-shared --enable-libxvid (+ a few others but I think these are the main important ones)

So mp3 should be compiled and working fine with this version of ffmpeg.

Then looking at the output of ffmpeg it seems that it detects the mpeg2 file, that the audio is in mp2 format and although it recognises several mp2 channels in the original file it maps the correct one with audio into the flv file.

So I'm not sure whats up because the handler.pl script is used for both the .asx stream and the flash player both of which have issues with sound!

Can I confirm that everyone is trying to stream mpg files captured from dvb card? As I think it could be something to do with this file format if mpeg2 (transcoded from analogue tv) from a pvr card streams fine.

It's a shame their suggestions didn't work. I was hoping to try that out soon. :(

I have tried with both DVB-T and PVR 250 recordings, and they both have the same sound problem, so I don't think the recording type is the issue.

Analog from a PVR doesn't work either. I have both a 250 and a 500, and MythWebFlash produces audio static with both.

I didn't find this thread until someone replied to mine at http://mysettopbox.tv/phpBB2/viewtopic.php?t=18612. I am experiencing a similar issue, except that I do get audio in all of my digital recordings (SD or HD), it is only the analog recordings that get static in the Flash conversion. Hopefully someone figures out the problem sometime.

Hmm. Since seems to be the current 'official' Mythweb streaming thread...

Has ANYONE gotten the streaming to work for mythweb, either by ASX or Flash?

My R5.5 install is nearly fresh out of the box. I get static for all flash recordings, and can't get any connection for ASX streams. (I click and WMP just hangs at "Connecting to Media...")

I've got the same result as you, tzoom...

In R5.5 I am able to play asx stream using wmp version 10.00.00.4058. I have tried several other programs but they failed. Could this be an authentication problem as wmp requires reentering username and password. VLC requests authentication but fails. I don't think multiple authentication is what was intended or was it??? What happened to MythstreamTV? I was able to stream to both desktop and pda using vlc and the mmsh protocol instead of the suggested mms.
