[Live-devel] OpenRTSP with Open Broadcast Software

[Jeff Shanab]

Does open broadcast need raw video as input? Live555 is a streamer only.
I decoded my frames using libavcodec(FFMPEG) and then apply them to a
texture using opengl or directx on windows,linux,mac,android or iphone.
same procedure for all.
Libavcodec decodes to YUV422 data, That is a luminance value for each pixel
and half as many of each chroma values. I used a shader in HSGL to convert
the YUV to RGBA in video hardware, but libavcodec has a sws_scale function
that can scale and color convert in main memory.
