Hi,

I am new to FFmpeg.

I am trying to create a small test ap that uses ATI's UVD hardware H264
bitstream decoder.

So far I have used the CPU FFmpeg decoder to decode the bitstream, and then
render it to the screen with an OpenGL pixel shader doing the YUV to RGB.

Now I am adding the hardware decoding part.

What I need from FFmpeg is:
The H264 stream such as the profile, level, width/height of the frame in
macroblocks, and various other detailed flags
like residual_colour_transform_flag etc. (the ATI docs say these are defined
in the H264 standard).
The raw bitstream divided up into NAL slices.

How can I do this with FFmpeg?

I found some stuff like level and profile in the AVCodecContext struct, but
I am missing all the really low level stuff that ATI need.
I also think that the AVPacket's data is the bitstream in NALs?

Thanks,
Leith Bade
