> PIX_FMT_YUV422P10 and PIX_FMT_YUV444P10 are 10-bit planar formats, delivered > in 3 (or 4, with alpha) planes of 16-bit integers, in the endianness of the > host platform (the actual pixel format has an endian postifix). The 10 least > significant bits of each integer represent the pixel component's value. > > In the context of OpenGL (on a little endian computer), push the planes onto > the GPU as 16-bit luminance integer textures (floating point may work as > well, with some different scaling). After sampling a single value, multiply > by 1023 to get to a 0.0 - 1.0 range. It's safe to assume that codecs using > this pixel format will be providing video level values, so you would need to > scale and offset as well to match openGL ranges.
<sigh> divide by 1023.0, not multiply. > > Bruce > _______________________________________________ > Libav-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/libav-user _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
