...n how to use libtheora but I'm having some problems: I believe to have encoded a video, but I can't decode it. I've tried 2 things: to record a .ogg file and to write a libtheora decoder, using the encoded ogg_packets present in memory. The source code is here: http://opensvn.csie.org/ribamar/projects/streaming/cvaenc.c (it has a makefile in http://opensvn.csie.org/ribamar/projects/streaming/Makefile and requires highgui and opencv to compile, in debian and ubuntu with universe it must be trivial to install them with apt-get install libhighgui-dev libcv-dev) 1) generating the ogg file...

.../www.fourcc.org/fccyvrgb.php I get an accurate color conversion but the contrast seems to be decreased. If i write, e.g., the pixel directly into an sdl yuv_overlay, I get a well-contrasted frame, however, if I convert the pixel to rgb and call SDL_MapRGB, I get a contrast-decreased frame. Thanks, Ribamar

...hen programming the decompress process, the strides were negative, and, so, yuvbuf.y[0] indicated the end of the y channel data. Is this true: positive strides => y[0] starts y channel data; negative strides => y[0] ends it? (again, are strides values specified anywhere?) Thanks in advance Ribamar

Hey, Commenting a SoC application about improvement of Etheora, Conrad Parker said the development should focus first on the encoding features since liboggplay is overlapping with Etheora. I'm transcripting the here so the Etheora's priorities can be better discussed by everyone (and searchable on the web). _____ Conrad, you mean concentrating first on encoding part, or pehaps
