Hi all, I'm trying to encode with --enable-libtheora. For smaller image sizes this seems to work, but beyond a certain size, I'm just getting segfaults with most recent svn (of ffmpeg i. e.). I've put my test video here: http://www.jarre-de-the.net/computing/test-2.avi and the resulting ogg here: http://www.jarre-de-the.net/computing/test.ogg This is my attempt: ~$ ~/Quellen/ffmpeg/ffmpeg -i test-2.avi test.ogg FFmpeg version SVN-r15151, Copyright (c) 2000-2008 Fabrice Bellard, et al. configuration: --enable-libtheora --enable-libmp3lame libavutil 49.10. 0 / 49.10. 0 libavcodec 51.71. 0 / 51.71. 0 libavformat 52.21. 0 / 52.21. 0 libavdevice 52. 1. 0 / 52. 1. 0 built on Sep 2 2008 09:48:12, gcc: 4.2.3 (Ubuntu 4.2.3-2ubuntu7) Input #0, avi, from 'test-2.avi': Duration: 00:00:11.90, start: 0.000000, bitrate: 550 kb/s Stream #0.0: Video: mpeg4, yuv420p, 728x462 [PAR 1:1 DAR 52:33], 10.00 tb(r) Stream #0.1: Audio: mp2, 44100 Hz, stereo, s16, 64 kb/s File 'test.ogg' already exists.
