Hello all, When I'm doing something like: yuv_buffer yuv; theora_decode_YUVout(&td,&yuv); I'm guessing a bunch of stuff gets newed/malloced for yuv.y, yuv.u, and yuv.u. Who is responsible for deleting/freeing that stuff? Cheers, Kos.

...working mostly (I'll explain the process in a bit), but when the app is running I get block artifacts, which look like small square bits of the image have been moved to the wrong place. The process I use for 3 and 4 is: To get the key frame: 1) Put the packet I saved into theora using theora_decode_packetin 2) Grab the decoded packet using theora_decode_YUVout 3) Read the YUV data into my own buffer To force the saved keyframe data back into theora: 1) call theora_decode_YUVout in order to get a YUV structure with its data members pointing somewhere usesful 2) copy the data I saved in (3) abov...

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

Hello, I am programmer working on a product which integrates Theora. I have a question regarding the memory use on some of the internals of Theora. Is this the right forum for this question, and if not, does anyone know where an appropriate place to ask is? Thanks Sam -------------- next part -------------- An HTML attachment was scrubbed...
