[XviD-devel] Timestamp question

[Edouard Gomez]

Hey christoph,
(i also post to xvid-devel, in case others can help)

I'm trying to debug a timestamp problem (at least it looks
like it is caused by timestamps) and i' like to have your
opinion.

Original file:
http://gigantic.ath.cx/xvid/test_huff.avi.bz2
(the directory contains the original bug report for xvid
1.0.1, i'm using to reproduce the crash on 1.1 branch, but the
divide by zero is gone, the blocking problem is still there
tho)

Encoded file available at:
http://ed.gomez.free.fr/vrac/plop.avi

Options used at encoding (note that i disabled closed GOV,
which you can't do because it's a flag in mencoder, so you
have to disable itin the ve_xvid4.c source):
mencoder -o plop.avi -nosound -ovc xvid -xvidencopts
pass=2:bitrate=-905:max_bframes=1:chroma_me:vhq=4:cartoon:trellis:min_iquant=1:min_pquant=1:min_bquant=1
test_huff.avi

Decoder output is as follow:
mplayer -fps 2 -vc xvid -xvidopts debug=-1 test_xvid.avi
-quiet 2>&1 | grep ^[IPB]
(i patched vd_xvid4.c to accept debug option, and i compiled
xvid with --enable-idebug option)
