* avcodec/vdpau_mpeg4: fix order of quant matrix coefficientsrelease/6.0Hendrik 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/vorbisdec: export skip_samples instead of dropping framesJames Almer2023-03-221-8/+3
| | | | | | | | | | | | | | | pts may not be set on input packets, which could result in the entire stream being discarded. This reverts commit 8fc2dedfe6e8fcc58dd052bf3b85cd4754133b17, reintroducing the behavior it replaced but now allowing the caller to manually drop the preroll samples by looking at the skip_samples side data at the start while ignoring it on seek, by setting the skip_manual avctx flag.

| | | | | | | | | | | | | | | | | | | already present Current mpegtsenc code only inserts SPS/PPS from extradata before IDR frames if AUD is also inserted. Unfortunately some encoders may preface a key frame with an AUD, but no SPS/PPS. In that case current code does not repeat the "extradata" and the resulting HLS stream may become noncompliant and unjoinable. Fix this by always inserting SPS/PPS and moving AUD to the beginning of the packet if it is already present. Fixes ticket #10148.
