Hmm, I have no idea...

OK, i have been trying version 1.2.6 and the CVS one, with both versions i still the the SegFault for both (glav and lavplay) programs...

Yes, "lav2yuv test.avi | yuvplay" wors, here is the output (a few lines...)

Yes, that one worked, but at the end test.wav cannot be opened, looks like there is a problem with mp2enc, if i play "foo.wav" with playwave it works,
[EMAIL PROTECTED]:/video/video> lav2wav test.avi > foo.wav INFO: [lav2wav] WAV done [EMAIL PROTECTED]:/video/video> playwave foo.wav Opened audio at 22050 Hz 16 bit stereo
But then after i did mp2enc -o test.wav < foo.wav i get this when i try to play the wavefile:
[EMAIL PROTECTED]:/video/video> playwave test.wav Opened audio at 22050 Hz 16 bit stereo Couldn't load test.wav: Unrecognized file type (not VOC)
Here is the output of mp2enc :
[EMAIL PROTECTED]:/video/video> mp2enc -o test.wav < foo.wav INFO: [mp2enc] Opened WAV file, freq = 44100 Hz, channels = 2, bits = 16 INFO: [mp2enc] format = 0x1, audio length = 4290048 bytes INFO: [mp2enc] slots/frame = 731 INFO: [mp2enc] frac SpF=0.429, tot bitrate=224 kbps, s freq=44.1 kHz INFO: [mp2enc] Fractional number of slots, padding required INFO: [mp2enc] System is little endian INFO: [mp2enc] Avg slots/frame = inf; b/smp = inf; br = inf kbps INFO: [mp2enc] Encoding with psychoacoustic model 2 is finished INFO: [mp2enc] The MPEG encoded output file name is "test.wav"
There is another thing that confuses me, the audio has actually 44100 Hz but the wav only has got 22050 Hz...
