similar to: a/v sync problem

Hi, When I sync the a/v with just an icecast2 stream I'm starting at the beginning of the stream so it's simpler. But, when I read the stream from icecast2/ezstream I get the stream after the beginning and the a/v timing on the packets need to be handled differently. Does anyone know what approach I should take to sync the live stream? There has to be some generic high-level logic for an

Hi, Is it correct to assume that after I get the headers of a stream like theora or vorbis the packet time can be computed as current_granulepos-first_granulepos ? This would give me the difference between the first media packet that is not a header and the current packet I decoded most recently. In a live stream I would have a clock from this calculation starting at zero. Thanks

Hi all, I am unable, using ffmpeg2theora 0.26, to encode this mpeg file in theora without audio/video sync problems : http://dl.rom1v.com/noindex/test.mpg The file works correctly using vlc or mplayer, but totem has sync problems for playing it. For information, it is a TV stream I recorded using : vlc

Hello all, Very new to Theora so apologies if this sounds elementary ;-) I'm trying to integrate a simple theora video player in my engine. All I need is simple load/unload and play/stop functionality. I'd also like to be able to stream from disk or mem. Other than the API reference I haven't found any example code, e.g. the sources for theora_player_example. Are these available

Hi, I wonder whether there is a webvidoeplayer for .ogg theora as it is for divx? http://stage6.divx.com/user/GarageFilms/video/1250263/Argentic-Bullet Anybody a link to a project for such a player?

Hi, I've been thinking about how a Theora encoder could be integrated into mencoder or transcode and I'm not sure whether I understand the A/V sync strategy of Theora/Vorbis correctly. When transcoding from some video format (ie MPEG2 or DivX), at least some images of the video stream will have time stamps, as well as the fragments of the audio stream. Or at least time stamps can be

Hi, I decided to try Theora and encoded a PAL DVD. I was very pleased with the result. It's better than "DiVX" for the same bitrate, I think, and the audio is clearly superior to MP3 audio. However, I'm having serious troubles encoding NTSC DVDs and getting the video and audio durations to match. I read some messages on this list about such problems and so what I am doing

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

I need to be exposed to a way of seeking theora streams. I have repeatedly found the same question asked on a different forums but could not find an answer. I'm working on a game and started integrating video with theora, the sound works just fine with ogg/vorbis(i find it easy to seek using ov_raw_seek for audio files). Could someone please point me to some example/code of how can i seek with

Hi, last week's thread about getting closer to a release fizzled out. The mailing list discussion and the TheoraTodo wiki item suggest the following are required for release: 1. freeze the theora logical bitstream format 2. complete the reference implementation tools 3. stablize the libtheora API 4. complete the documentation I'd like to suggest this as

Hi, I am a beginner for theora. Now I am trying to understand the code of theora codec. If you can show me the correct path for understand the code (which codes must understand first), it may be easy to understand code properly. -- Nuwan Millawitiya

New version of ffmpeg2theora, a command line tool to convert video files to Ogg Theora. new in version 0.19 - use libswscale api - add frontend mode and a simple PythonCard Frontend (only in svn right now or binary for os x *) - support for output larger than 2GB on 32bit systems - fix short option -k to output Ogg Skeleton - other smaller fixes binaries

We are scheduling another meeting to discuss Theora matters. One of these was planned just a while ago, but it pretty much didn't happen. So let's make this one happen. Anyone interested in Theora or video technologies is welcome to attend. The place is #xiphmeet at irc.freenode.net, this Tuesday at 14:00 UTC. If you don't know when 14:00 UTC is, go here[1] for conversion into

Hi, I want to use theora as video playback solution in game engine, so far i have successfully implemented basic video playback (load a file and play it in game engine). I have based my implementation on example player but i have used new theora functions (the th_ ones). It works ok, but i have a problem with implementation of video seek and loop, i also don't have proper time sync. I

Hi there, the attached patch for theora-tools adds UTF8 support to theoracomment; however, for this I did copy some "shared" files from vorbis-tools to theoracomment. I'm not sure whether you want this but rather make them shared in theora-tools, too? Additionally, I added header-comments in the style of theoraenc and a manpage. So far, theoracomment looks rather complete now

Hello all, I'm coding (trying to code should be better) a soft in python to analyze video. (scene change, edge, line, motion) and i want to use ogg file. So i got a few questions : To analyze the video i need an acces to the video data (the array of pixel) and i'm wondering if i can acces it directly, i mean by my own or do i really need to use the decode process to get an array of RGB
