Hi, in the past two days I wrote Python bindings to libtheora: http://github.com/certik/python-theora Currently it can read any ogv file (that seems to work quite well) and also encode to ogv (this mostly works, but there are some subtle issues to be fixed, I suspect I still have some bug in the way I half the dimensions of the Cb and Cr planes, so when you read ogv and write ogv, the resulting image is not exactly pixelwise ex...

hi, there is a problem when i convert some mpeg files to ogv with libthusnelda I 20090527... i don't know it this helps you but i am sending information about it... when i convert an mpeg file ro ogv, there are macro block artifacts on the lower part of the video... but it doesn't happen all the time... description is below and you can download the...

Hi, I'm new here - thanks for having me. (Sorry if I'm in the wrong place or a noob.) I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a sequence of bitmaps, and created an OGV file. The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else with it: I tried uploading to YouTube, and the video just comes out really corrupt: http://www.youtube.com/watch?v=sHaMG6mcWu0 I tried using ffmpeg to convert to another format, but it gives errors (listed belo...

...I generated this intro video in Ogg/Theora from a sequence of png files. I would need to do this in an automatic script, because I have many such videos to process, and without doing any re-encoding step (which would be very costly because my videos are huge). I tried to use oggCat: oggCat final.ogv intro.ogv video.ogv Unfortunately, this doesn't work well because my intro video has no sound track to be concatenated with the one in the real video. As a consequence, the concatenated video only has a video track. It tried to add a silent track to my introduction video (same bitrate) with o...

Hi good people, Just to inform: I finally fed FFMpeg2Theora with a .VOB input, and the .OGV output produced played back beautifully in VLC, both audio and video. However, the same output .OGV file gave clicks and pops in the audio when fed through Directshow programs. I played it through Windows Mediaplayer as well as through Winamp, with the same crackles in the audio, and this leads m...

Hi J., We are using ffmpeg2theora to produce an introduction video from a series of images: ffmpeg2theora-0.26.linux32.bin images/img-%03d.png -o intro.ogv The video that we get is huge and horrible, with lots of blinking colors: http://free-electrons.com/issues/ffmpeg2theora-mar5-2010/intro.ogv Here's what we had in the past: http://free-electrons.com/issues/ffmpeg2theora-mar5-2010/intro-correct.ogv This issue was introduced in ffmpeg2theora-0...

Hi, I'm trying to add Title and other metadata to OGV, when encoding with ffmpeg2theora 0.24. Unfortunatelly, mplayer and VLC is not showing any metadata. Shall this work with ffmpeg2theora 0.24? Exist something like vorbiscomment to check / do it with OGG/Vorbig/Theora? Thank you, Jiri

I need some info on how can I read the audio data from an .ogv video. I'm creating an in-game player and so far I'm only able to read and render the frames of the video (no audio). Tried splitting the video from the sound but it got out of synch really quickly. Thanks, -------------- next part -------------- An HTML attachment was scrubb...

Hi folks,I'm joining this list because I've encountered difficulties with the ogg tools. I'm running Windows, and can't find binaries for liboggz tools, such as oggz-merge.exe Can someone provide oggz-merge.exe? So I use ffmpeg (v19289) for muxing ffmpeg -y -i sync2.ogg -i sync.ogv -vcodec copy -acodec copy sync2.ogv but the framerate fluctuates wildly on playback, and ogginfo says its corrupt E:\mediatests\sync>ogginfo sync2.ogv Processing file "sync2.ogv"... Note: Stream 1 has serial number 0, which is legal but may cause problems with some tools. New logical...
