That means one audio chunk spans several video frames. +avisplit can not cut a chunk in half, it only handles complete +chunks. If you do, say, avisplit -s 20, it is possible that the first file will +have 6 audio chunks and the second one only 4 meaning there is too much +audio in the first AVI file. + +The solution is to remux the AVI file with +.RS +.B transcode -i in.avi -P1 -N 0x1 -y raw -o out.avi +.RE +(of course -N 0x1 is not correct for all AVI files). +Now look at tcprobe again + +.br + | V: 25.000 fps, codec=dvsd, frames=250, width=720, height=576 +.br + | A: 48000 Hz, format=0x01, bits=16, channels=2, bitrate=1536 kbps, +.br + | \fI250\fP chunks, 1920000 bytes +.br + +The data in this file is \fIexactly\fP the same (its bit-identical) +as it was in in.avi; the AVI file was just written in a +different way, we do now have 250 audio chunks which makes splitting much +easier and more accurate for avisplit. +.SH AUTHORS +.B avisplit +was written by Thomas Oestreich +.br +<[email protected]> with contributions from +many others.
