View Full Version : Video encoding under Linux impossible

I was in the past able to encode perfectly using either mencoder or transcode (the former in divx4 compatibility mode, and the only way to get good A/V sync).

However, with the CVS code, transcode segfaults. Running a backtrace in gdb shows that it crashes in encode_bframes in the xvid core. Commandline was:

transcode -q 128 -V -A -M 4 -N 0x2000 -j 0,8 -f 0,1 -w 1500 -y xvidcvs

On the mencoder side, it encodes without errors, however, the output is garbled (examples below). Playback is the same under Linux or under Windows with XviD or ffdshow.

My guess is that its not able to correctly deliver the data to XviD in divx4 compatibility mode anymore.

p.s. Does anybody monitor the forums on the Xvid site?

You'd probably have better luck posting this to the xvid-devel at xvid.org mailing list. A couple users do quite a bit of encoding under *nix and could give you a definite answer.
