Thank for your response Victor,
Unfortunately the processing would still be performed by the CPU unless I’m
Hardware acceleration of H.264 would be more practical as it would be useful to
all ffmpeg users. Consider that decoding a H.264 stream at a res. of 1080p with
a high bitrate creates about a 100% load on single core CPU, about 80% for
dualcore CPU, 30%~40% for qaudcore CPU which doesn't leave much room for
post-proc. With hardware decoders the CPU would be free to perform other task
like real-time NLE. I hop someone dev’s understands the importants of such
implementations and the different way this can be useful to ffmpeg users...
