* avcodec/vdpau_mpeg4: fix order of quant matrix coefficientsrelease/4.4Hendrik Leppkes2023-05-151-2/+3
| | | | | | The matrix coefficients are stored permutated for the IDCT, rather then in plain raster order, and need to be un-permutated for the hardware.

* avcodec/libsvtav1: remove compressed_ten_bit_format and simplify alloc_bufferChristopher Degawa2023-05-121-7/+3
| | | | | | | | | | | | | compressed_ten_bit_format has been deprecated upstream and has no effect and can be removed. Plus, technically it was never used in the first place since it would require the app (ffmpeg) to set it and do additional processing of the input frames. Also simplify alloc_buffer by removing calculations relating to the non-existant processing.
