Updated version of video preview covering frame writing every 3 keyframe and a xsl typo. Best regards :) kysucix -- Make things as simple as possible, but no simpler. - Albert Einstein

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

...ease: * first draft of the Theora I Format Specification * API documentation generated from theora.h with Doxygen * fix a double-update bug in the motion analysis * apply the loop filter before filling motion vector border in the reference frame * new utility functions: theora_packet_isheader(), theora_packet_iskeyframe(), and theora_granule_frame() * optional support for building without floating point * optional support for building without encode support * various build and packaging fixes * pkg-config support * SymbianOS build support We still plan to make incompatible api changes before the first beta rele...

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

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

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
