I have a .mkv that fuppes is transcoding to mpg. This works fine.
Fuppes is also transcoding the liba52 audio to stereo mp2. This is where I'm having a problem. The resulting audio sounds terrible, seemingly void of all the higher-pitched sounds. Here's the relevant section of fuppes.cfg:
Here's the output on the fuppes console:
Duration: 01:40:56.6, start: 0.000000, bitrate: N/A
Stream #0.0(eng): Video: h264, yuv420p, 1280x544 [PAR 1:1 DAR 40:17], 23.98 tb(r)
Stream #0.1: Audio: liba52, 48000 Hz, 5:1
Output #0, mpeg, to '/tmp/fuppes/1.mpg':
Stream #0.0: Video: mpeg2video, yuv420p, 1280x544 [PAR 1:1 DAR 40:17], q=2-31, 1800 kb/s, 23.98 tb(c)
Stream #0.1: Audio: mp2, 44100 Hz, stereo, 192 kb/s
Stream #0.0 -> #0.0
Stream #0.1 -> #0.1
No accelerated IMDCT transform found
... not sure if I should be concerned about that last line?
As a test, I used ffmpeg to convert the video with the same options that fuppes would be using:
ffmpeg -i movie.mkv -vcodec mpeg2video -b 1800000 -acodec mp2 -ar 44100 -ab 192000 -ac 2 -ab 192000 -r 44100 -f mpegts -y movie.mpg
.. the resulting .mpg can be streamed to my PS3 with great sounding audio. This makes me think it's related to fuppes' "on the fly" transcoding. Any ideas?
On a side note, I think I misunderstand what transcoding_release_delay is supposed to do. In my PS3 device section I can set this to 50, 500, or 0 - all with no obvious effect. I would expect this to create a delay before fuppes sends the transcoded file to my device (kinda like buffering)?
I'm currently using r586
