I stumbled over the Wikipedia-article that the Broadcom GPU has hardware support for encoding H.264/AVC, not only de-coding.
I also found an article where someone gave an example using
ffmpeg to generate a h264/mp4 video files. Ok, its a general-purpose CPU with a specialised GPU, so that's not really the surprise.
But compared to a standard desktop PC with an average Graphics-Card, will the Raspberry Pi potentially encode H.264/AVC maybe even faster? If a desktop user was to optimize his
ffmpeg to his Core-i5xxx with $150 Ati/Nvidia graphics card... does that combination offer anything in the ways of "hardware H.264 encoding support"? If not, will a specially adopted Raspberry-Pi-ffmpeg be even faster? If yes, is there a speed comparison already?
