similar to: Encoding theora...

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

Can someone enlighten me on what the status is of aspect ratio in theora is ? The ti structure has aspect_num and _den values, which I assume give the intended display aspect ratio (e.g. 4/3). The sample files on the bittorrent seem to say both values are 0 for all files. I'd think it should at least be made impossible to have a 0 as the denominator. The library doesn't check the

Hi There, i want to stream some pictures out of my application using the Theora codec. I can stream to a socket or a file. The current work based on the png2theora example. Something while enconding went wrong: I can see the whole video in VLC, but the complete duration of the file will not be displayed. If i play the video in Firefox, the first 2 seconds will not be played. I think the

I have almost finished integration of Theora into our videoconferencing program. Since a videoconferencing program is realtime, it is UDP-based and wraps the Theora stream in RTP (More on that later). The problem here is that most examples I could find, wraps the theora stream in ogg, and used over tcp or files. I send over UDP and clients need to be able to start in the middle of the stream.

I am giving serious consideration to abandoning waveOut multimedia and the wav format, for most of the audio in my C++/MFC project. However, I've never done any programming with a codec, and I still can't see how to step into Ogg Vorbis. If I convert all my wav files to ogg, there seem to be two major issues I'm facing: 1) What exactly will I replace my waveOut functions with? 2)

Hello, I wrote a theora video encoder based on etheora (and the examples provided with it) for Processing IDE (processing.org). I have some problem with the quality of encoded frames. eg. http://poux.be/tmp/movie.ogg And when I play the movie with mplayer or totem, the video resolution is changed from 640x480 to 854x480 (when i use ETHEORA_ASPECT_NORMAL in etheora_enc_setup). And if I try to

For last few days I was trying to learn ffmpeg and libtheora API. In the process, I have modified ffmpeg2theora code to include support for start time and end time. ffmpeg2theora -s 60 -e 130 file.avi will produce file.ogg which will be from 60th to 130th second of input file (something like -ss and -endpos in mencoder). This is a useful feature for someone who wants to cut a part of video

Hello everyone, I'm currently developing an adaptive videoconferencing application based on Ekiga which uses TFRC as a congestion control mechanism to adapt the video encoding rate according to the quality of the network experienced. My goal was to use the open-source Theora codec for video transmission. Unfortunately, it seemed that Theora 1.0 did not properly implement any correct CBR mode.

Hi all, Xiph aims at developing open-standards media formats. Though xiph.org tells about vorbis/theora/flac/speex, nothing is mentioned about container to use (that is ogg/ogm). I have a few questions Is there a difference between ogg and ogm? I guess its only the extension that is different and everything else is same. Some tools (like ogmtools) are available to create ogm files. What is

At my company we have a bunch of music in FLAC format. We want to play it using the Windows Media Player, but none of us can get the illiminable DS filters to work. Here are some details. Illiminable DS filters http://www.wmplugins.com/ItemDetail.aspx?ItemID=681 http://www.illiminable.com/ogg/ We are using the latest build available on this website, and I have read all the known issues.

I've got my encoder working now... and i put a proeprty page interface to allow the user to set a few encoding paramters to start off with... but changing the paramters doesn't seem to make barely any difference... These are the defaults i'm using... mTheoraInfo.target_bitrate=400000; mTheoraInfo.quality=30; mTheoraInfo.dropframes_p=0; mTheoraInfo.quick_p=1;

I am trying to write a sample app that uses Theora for encoding/decoding a network video stream. Unfortunately, I keep running into this error: Run-Time Check Failure #3 - The variable 'MVect' is being used without being defined. It always happens on decryption, line 467 in decode.c. The issue is that CodingMethod is equal to 5 (CODE_GOLDENFRAME), which doesn't initialize the

Another update to these filters... www.illiminable.com/ogg/ Here's the chagnes... * FLAC can now be muxed into a multi-stream file. * Now supports both the new Ogg FLAC (1.1.1) and the old Ogg FLAC (still not native FLAC) * Fixed the explorer problem by removing the offending registry key at installation * Removed a heap of memory leaks, WMP should run a fair bit leaner now * Some internal

Updated again... theora works and seeks properly (not to keyframe) in WMP 9 and 10. You can encode from a bunch of onew input types like RGB32, RGB24, IYUV etc. And fixed a bug that was stopping the filters being used in a activeX control in an IE browser. www.illiminable.com/ogg/ Enjoy, Zen.
