* Use separate NVDEC contexts per channel (for FFMPEG) * Remove NVDEC -> VIC frame override hack * Add missing bottom_field_pic_order_in_frame_present_flag * Make FFMPEG logging static * nit: Remove empty lines * New FFMPEG decoding approach -- call h264_decode_frame directly, trim surface cache to reduce memory usage * Fix case * Silence warnings * PR feedback * Per-decoder rather than per-codec ownership of surfaces on the cache
