This is a rather radical change: instead of maintaining a whitelist of FFmpeg formats we support, we automatically support all formats. In general, a format which doesn't have an explicit IMGFMT_* name will be converted to a known format through libswscale, or will be handled by code which can treat pixel formats in a generic way using the pixel format description, like vo_opengl. AV_PIX_FMT_UYYVYY411 is a special-case. It's packed YUV with chroma subsampling by 4 in both directions. Its component order is documented as "Cb Y0 Y1 Cr Y2 Y3", meaning there's one UV sample for 4 Y samples. This means each pixel uses 1.5 bytes (4 pixels have 1 UV sample, so 4 bytes + 2 bytes). FFmpeg can actually handle this format with its generic mechanism in an extremely awkward way, but it doesn't work for us. Blacklist it, and hope no similar formats will be added in the future. Currently, the AV_PIX_FMT_*s allowed are limited to a numeric value of 500. More is not allowed, and there are some fixed size arrays that need to contain any possible format (look for IMGFMT_END dependencies). We could have this simpler by replacing IMGFMT_* with AV_PIX_FMT_* through the whole codebase. But for now, this is better, because we can compensate for formats missing in Libav or older FFmpeg versions, like AV_PIX_FMT_RGB0 and others. |
