Unfortunately, the patch actually made things worse. The "error, non
monotone timestamps" stuff was still there on the 16,48,80 (problematic)
values and the audio was still messed up. Furthermore, non-problematic
values caused ffmpeg to *transcode* from test.avi into cutfile.avi
instead of just cutting. Whereas before the cut command was almost
instantaneous (which makes sense under the -acodec copy -vcodec copy
conditions), the patched ffmpeg now takes much, much longer as if I were
transcoding from one format to another.
Thanks for the attempt. Let me know if you need any more information.
