I can confirm this. But! $ lav2wav nits_short.mov | mp2enc -o audio_short.mp2 INFO: [mp2enc] Opened WAV file, freq = 48000 Hz, channels = 2, bits = 16 INFO: [mp2enc] format = 0x1, audio length = 2147483392 bytes INFO: [mp2enc] SpF=672, frac SpF=0.000, bitrate=224 kbps, sfreq=48.0 kHz INFO: [mp2enc] System is big endian **ERROR: [lav2wav] rewind failed - wav-header is corrupt INFO: [mp2enc] Num frames 1334 Avg slots/frame = 672.000; b/smp = 4.67; br = 224.000 kbps INFO: [mp2enc] Encoding to layer 2 with psychoacoustic model 2 is finished INFO: [mp2enc] The MPEG encoded output file name is "audio_short.mp2" So for me it fails also with mjpegtools-1.9.0rc1, as well as with mjpegtools as of 2007-02-20 (last cvs where I don't experience the random quantisation jumps). c -- __ _ _ _ __ _ _ \ \ | |__| |__ _ __| |_\ \| |_ _ _ __ _ __| |_ \ \| '_ \ / _` / _| / /\ \ _| '_/ _` (_-< ' \ http://www.blacktrash.org/ \_\_.__/_\__,_\__|_\_\ \_\__|_| \__,_/__/_||_| Jabber-ID: [EMAIL PROTECTED] ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
