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 --audioquality is -1 and the lowest acceptable value for --audiobitrate is 45. Anyone know what'...

Hi, When an audiopacket is received too late I could interpolate this frame. The problem is that I don't know if it is a true bufferloss or just the last audiopacket of a talkspurt. Now my question is if it's harmfull for the audioquality that at the end of the talkspurt one frame is interpolated? Or would this be almost inpossible to hear since the last audiopacket in the talkspurt already is about silent? This obviously depends on how speex interpolates a frame.

hi everybody. i'm currently looking for a good SIP-softphone. i tried x-lite but i'm not happy with it's soundquality as there is a very high noiselevel. do you know a better softphone? and would a hardware SIP-phone offer (almost) the same audioquality as my isdn-phone? if so what phone would you recommend (and where can i get it in germany)? thanks!! bye thorsten -------------- next part -------------- An HTML attachment was scrubbed...

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. Did you remember to specify an est...

...derstand, creating alossy libraryor any library based on a proprietary format was deemed absurd. FLAC was our starting point and still seems to be the logical choice for the next generation of music distribution file formats....including high-resolution files for those that care even more about audioquality. One of theprimary underlying assumptions comprising the foundation of this project was that future music distributions will inevitably be file-based and free of the encumbrance of optical discs in any format. Discs don't make sense, but compatible, searchable libraries do. Users need...

I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the

Hi all, I've been looking at opus lately as a replacement to vorbis and it sure seems to me that, at least on paper, it is the 'next generation' streaming codec. Has anyone been using opus as a streaming codec to Icecast? If so, how do the following general characteristics compare to vorbis? + Quality + Latency + Bandwidth + Performance (on stream client and Icecast server) +
