Public bug reported: Binary package hint: vorbis-tools
oggenc ignores the command line switch --ignorelength, which should enable it to process WAV files bigger than 2GB. In the current maverick version (also in the upstream trunk) dumping a DVD 5.1 audio track with mplayer and feeding the WAV to oggenc will stop encoding always exactly after 62 minutes of audio, or to be more precise after 3728.2 seconds. Usual command line is: $ mkfifo ./tmp/fifo $ oggenc --ignorelength -q1.9 -o tmp/audio.ogg ./tmp/fifo & $ mplayer -really-quiet -channels 6 -aid 128 -ao pcm:fast:file=./tmp/fifo dvd://1 WARNING: WAV file uses side surround instead of rear for 5.1; remapping side speakers to rear in encoding. Opening with wav module: WAV file reader Encoding "/home/lnieves/tmp/tmp/fifo" to "/home/lnieves/tmp/audio.ogg" at quality 1.90 [100.0%] [ 0m00s remaining] \ Done encoding file "/home/lnieves/tmp/audio.ogg" File length: 62m 08.0s Elapsed time: 7m 55.9s Rate: 7.8349 Average bitrate: 167.3 kb/s The original audio track is, of course, longer than 62:08 minutes. In this case, the track is 163 minutes, but I have tested with other DVDs always getting the same 62:08 minutes of resulting vorbis encoded. The problem is that mplayer sets the size on the WAV header to 2GB and oggenc then stops when it reaches that point. 2 GB corresponds to 62 minutes for 48 kHz, 6 channels, 16 bits/sample 2*1024³/(48000*6*2) = 3728.27 s = 62m08.27s. I attach a patch for vorbis-tools-1.4.0/oggenc/audio.c after which the same command above processes the full audio track: $ oggenc --ignorelength -q1.9 -o tmp/audio.ogg ./tmp/fifo & $ mplayer -really-quiet -channels 6 -aid 128 -ao pcm:fast:file=./tmp/fifo dvd://1 WARNING: WAV file uses side surround instead of rear for 5.1; remapping side speakers to rear in encoding.
