Hi Taylor! You’ll have to provide the runtime log, information about your distribution and mplayer builds, and anything else that you think is relevant so I can try and debug things. Thanks

Hey man, the script generates the mp4 video but I have no audio. You said you don’t support this anymore but you were still responding to people’s comments. Any idea what could be up? Thanks.

At the time I wrote the script, the published Microsoft document[1] specified it'll only play 2.1 when you're decoding h264. Looks like this hasn't been fixed, it's a little crippling. This was something I was going to write about earlier, I was very annoyed at the time, as I'm running an optical cable to my 5.1 receiver as well, but I wanted a solution to play HD content on my Xbox 360 quickly so I went with two channel audio.

I do have one question…Would it be possible to remux the file but instead of dropping the audio down to 2 channel’s you leave it as it is? (5.1) I have my xbox running to my receiver and .avi files that are encoded with 5.1 play in 5.1 through uShare. Is this possible with remuxing them to .mp4?

Gota say it again many many thanks for putting this together and sharing!

I got it working just fine…Very nice script…I’m using Ubuntu Karmic and the packages I grabbed work perfect with your script. I did add the mkvtoolnix repo’ so I it would grab the latest version’s. http://www.bunkus.org/videotools/mkvtoolnix/downloads.html
then I just grabbed the other’s without adding any other repo’s downloaded the nero program and ran a 720p mkv TV download through your script and it worked perfectly. Many thanks for putting this script together!

p.s. I use ushare to stream to my 360 and is all I had to do was rename the .mp4 to .avi and ushare streamed it just fine like that.

Sorry, after actually reading the rest of the thread I suspect that people have been reporting different audio problems, and other scripts are also experiencing similar issues. My assuming that your work is pieced together from stuff off the internet (in the same way that all of mine is!) is a bit of a logic leap, apologies for that.

So… I think I just found a simple typo on the modified mplayer line – no dollar on the SOURCE variable.

Cheers!

Just wanted to say thanks for making this script. It saves me a lot of time doing all this by hand.

Awesome job

If anyone is still trying to get this script to work in 9.10 you need to go to line 131 and replace:

mplayer “$SOURCE” -vo null -vc null -ao “pcm:fast:file=$DEST.wav” -channels 2 >>”$log” 2>&1 &

with:

mplayer “$SOURCE” -vo null -vc null -nocorrect-pts -ao “pcm:fast:file=$DEST.wav” -channels 2 >>”$log” 2>&1 &
