[mythtv-users] Why is DVD burning failing with ffmpeg?

[Nick Gomez]

When ffmpeg is called from mytharchive the command designates both the audio and video stream options. For instance, the ffmpeg command for LP is:

ffmpeg -v 1 -i "/mnt/store/temp/work/1/tmp" -r ntsc -target dvd -b 2344k -s 352x480 -acodec ac3 -ab 192 -ac 2 -copyts -aspect 4:3 "/mnt/store/temp/work/1/newfile2.mpg" -map 0:0 -map 0:1

When I ran this from the command line, I got the error:

Stream #0.1: Audio: ac3, 48000 Hz, stereo, 0 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
Error while opening codec for output stream #0.1 - maybe incorrect parameters such as bit_rate, rate, width or height

Notice the 0 kb/s for the audio stream. So I went into the profile xml file and deleted the following lines.

...
        <parameter name="-acodec"      value="ac3"/>
        <parameter name="-ab"          value="192"/>
        <parameter name="-ac"          value="2"/>
...

I then tried mytharchive again and had success.

It is also of note that ffmpeg fails during video encoding, not  
audio.  So, although they may have very well changed the audio  
requirements, we need to get past the video issue first.

Thanks,
