ffmpeg/x264 Segmentation Fault Error (2nd try)

*Sorry that last email sent itself way too early...* I have been having this problem for a while and upgraded both ffmpeg/x264 based on recommendations on this discussion group, but I am still having issues. Any help would be great, I really have to get this issue resolved quickly. First things first, versions and config: ffmpeg: FFmpeg version SVN-r14662 configuration: --enable-shared --enable-libmp3lame --enable-gpl --enable-libfaac --enable-libfaad --enable-libx264 --enable-libxvid --enable-pthreads --enable-libvorbis --enable-libamr-nb --enable-libamr-wb --enable-nonfree libavutil version: 49.7.0 libavcodec version: 51.63.0 libavformat version: 52.19.0 libavdevice version: 52.0.0 built on Aug 7 2008 23:49:18, gcc: 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) x264: x264 core:60 r0+928 4816918 Command Example: ffmpeg -i dave.mov -ar 22050 -vcodec libx264 -y -f flv dave.flv Error Example: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x61a550]negative ctts, ignoring Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'dave.mov': Duration: 00:01:43.36, start: 0.000000, bitrate: 2408 kb/s Stream #0.0(eng): Audio: libfaad, 48000 Hz, stereo, s16 Stream #0.1(eng): Video: h264, yuv420p, 568x320, 23.98 tb(r) Output #0, flv, to 'dave.flv': Stream #0.0(eng): Video: libx264, yuv420p, 568x320, q=2-31, 200 kb/s, 23.98 tb(c) Stream #0.1(eng): Audio: libmp3lame, 22050 Hz, stereo, s16, 64 kb/s Stream mapping: Stream #0.1 -> #0.0 Stream #0.0 -> #0.1 [libx264 @ 0x64a200]width or height not divisible by 16 (568x320), compression will suffer. Segmentation fault Yes, I am aware that my example video already has an h264 video codec. It doesn't matter, I get that error with any video I try to convert using the -vcodec libx264 flag. If I leave it off its not problem, works just fine. I am at a loss, the error is way too vague to troubleshoot. What might I be doing wrong? I have current versions (as far as I can tell) and everything seems to be installed correctly. It used to work on this box just fine until one day I recompiled a newer version of ffmpeg, ever since its hasn't converted to H264. PLEASE HELP! THX.

segfault with libtheora

Compiling ffmpeg for Windows Mobile (ARM4VI). Help
by EKSSIM＠ntu.edu.sg 02 Sep '08

02 Sep '08

Hi, I need to build a simple video player on Windows Mobile and I was looking at ffmpeg. I have tried to cross-compile ffmpeg using MingW + Msys + Cegcc and also Cygwin + Mingw32ce toolchain but was unable to get it to work. Do I need to modify any ffmpeg codes to get it to compile? Anyone kind enough to provide me with detail instructions on compile the codes to Windows Mobile? Meanwhile, I will be pulling my hair. Thanks in advance Alan Sim

ERROR: Xvid not found for I want to use static link
by chinesealexander＠163.com 02 Sep '08

02 Sep '08

Dear ffmpeg stuff: I compilered the xvid lib to be xvidcore.a(821K) and xvidcore.dll (726K). I want to use the static library to be linked with ffmpeg,so I renamed the xvidcore.dll then it can't find the xvid. How can I do for using xvidcore.a only? not use the dll? $ ./configure --enable-shared --enable-memalign-hack --disable-static --enable- vhook --enable-libxvid --enable-gpl add_extralibs: (* * ) check_lib :(* zlib.h zlibVersion -lz * ) check_lib :(* math.h sin -lm * ) add_extralibs: (* -lm * ) check_lib :(* xvid.h xvid_global -lxvidcore * ) ERROR: Xvid not found If you think configure made a mistake, make sure you are using the latest version from SVN. If the latest version fails, report the problem to the ffmpeg-user at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.err" produced by configure as this will help solving the problem.
