(ogminfo.c) OGG stream 2 is of an unknown type (bad header?) (ogminfo.c) (a1/serial 1092562206) Vorbis audio (channels 2 rate 48000) Is possible, that ogminfo is older then ffmpeg2theora ?

Hello, So far I used this command to convert video files: ffmpeg2theora.linux --optimize --no-upscaling --videoquality 5 --audioquality 1 --contact=http://navratil.cz a.mp4 Now I'm trying use --two-pass parameter with ffmpeg2theora 0.25+svn16645 - Xiph.Org libtheora 1.1 20090822 (Thusnelda) if I just add --two-pass, then I'm getting Could not set up the first pass of two-pass mode.

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)?

Hello, I'm finishing my preparation to distribute video recording from Software Freedom Day 2010 on a HTML5 page with references to video files I had converted thx to ffmpeg2theora to Ogg file with Theora video and Vorbis audio. I have the video files already converted and I wish to add some metadata to video file (and propably to HTML5 page too?) I'm thinking about year, copyright,

I built ffmpeg2theora from SVN, using libogg 1.1.4, libvorbis 1.2.3 and Thusnelda from SVN. Running ffmpeg2theora --help reports that ffmpeg2theora accepts a range of -2 to 10 for the --audioquality option and a bitrate of 32 to 500 for the --audiobitrate option, but it doesn't appear to actually accept any of the low end numbers. It appears that the lowest acceptable value for

When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds. Here is ffmpeg2theora output: $ ffmpeg2theora --optimize --inputfps 25 -F 25 2002-05-23\ Juho\

Here's another problem I have with the 0.24 version of ffmpeg2theora. When I try to convert a h264 file to theora...

Hello, hope you can help me. I want to encode a video, which I have exported from Keynote (a program for presentation like MS Power Point) using ffmpeg2theora for html5 web delivery. The result only plays very buggy - frames are dropped, the video hangs and vlc can not output the correct length of the ogv video. Here is the source and the result for download, if you want to reproduce it: the

Hello, Thank's to fast replies on this list, I can now encode to Theora from demuxed files. Thank you again. So far, I used Vorbis + H.264 (Mencoder, x264, double pass) in Matroska.

First result show me, that with video bitrate = 1000, the Ogg file have doubled size
