Hello everybody, I've been doing a lot of hacking on DisplayLink USB graphics cards. I'm not an expert on video decoding, so I'd like to hear your opinion on my idea.
The acceleration capabilities of these devices are pretty limited: they can basically do arbitrary framebuffer writes (pixel data can be compressed with a custom Huffman code) and bitblt inside the framebuffer. So any sort of conventional video streaming won't work, at least not really well. However, I've been thinking that at least 720p video might be possible if some of the advanced compression techniques of, e.g., MPEG could be used directly on the device. So what I'd like to get from ffmpeg is the block motion information and not whole frames, but just the pixel data for new blocks. Is this possible/does it make sense?
