Seek problem 2 - reinitialization of the decoder
...ough data... load some more pages! bufferData(); } else if (result > 0) { theora_decode_packetin(&decoder, &packet); int videoBufferTime = theora_granule_time(&decoder, decoder.granulepos); int frameNo = theora_granule_frame(&decoder, decoder.granulepos); if (theora_packet_iskeyframe(&packet) == 1) { ... The problem is that the time and framenumber are not correct - in fact they are offset with something that's either completely random or influenced by whatever state the decoder had before the seek (I don't know which). So my immediate fix was to just rea...

[PATCH] icecast video preview
Hi. Here it is my patch to put a video preview of a theora stream in status.xsl. I just added a: <video-preview>1</video-preview> parameters in icecast.xml.in that control the previewing function. It encodes a png in $webroot/$mountname.tmp and then move it to $webroot/$mountname.png As for now it saves a frame every theora keyframe, which is probably too heavy for the server but

Skipping Frames
Hi everyone! I'm currently trying to use the theora decoder on PPC. Everything is working perfect now, but I have a problem: I need to skip the decoding of some frames (drop frames) when the device is not powerful enough to decode them all in real time (which in PPC is a frequent issue). Right now, I'm skipping the call to theora_decode_YUVout and the yuv to rgb procedure. That gives me

ogg and keyframes
Hi, When doing a live ogg+theora stream on our server we ran into the following problem: When a client connects we send out the theora header pages followed by the actual live stream pages. The problem is that the first ogg data page does not have the right page number (2), which causes libogg to not want to decode the first _packet_ of that page. Since that first packet happens to contain the

ogg + theora + seeking
Hi all, I'm actually learning how to use ogg, theora and vorbis. My idea is to create a small program running, that is able to concatenate ogg video+audio files. However I have some small questions. Here I will start with the first one: I read the following for seeking in ogg for a theora key-frame: ---- snipp (http://www.xiph.org/ogg/doc/ogg-multiplex.html) ---- [...]The third point
