We specifically opted to use the 2D GPU to do a format conversion, as this yields a RGB internal representation, which means the texture has the same properties as a normal GL texture (e.g. glReadPixels works). This way we can expose YUV format imports as non-external textures. This provides a number of benefits in texture lifetime handling in the upper layers of the stack, which are used to drive those video use- cases, like GStreamer. I don't really care what the blob does, but I do care about having the highest performing solution, which is to have the 2D GPU work in parallel with the 3D GPU and allow efficient texture imports with GStreamer. I would really appreciate a review of my patch series.
