* avcodec/vorbisdec: export skip_samples instead of dropping framesJames Almer2023-03-22
| | | | | | | | | | | | | | | 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. Fixes ticket #10251. Suggested-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: James Almer <jamrial@gmail.com> (cherry picked from commit cbcc817353a019da4332ad43deb7bbc4e695d02a)

| | | | | | | | | | | | It is currently abused to store packet size, which breaks AV_CODEC_FLAG_COPY_OPAQUE. Use stream_index instead, which is unused in libavcodec and has the same type as size.

Before calling MFXVideoENCODE_Reset, The application needs to retrieve any cached frames in the SDK encoder. A loop is added before MFXVideoENCODE_Reset to retrieve cached frames and add them to async_fifo, so that dynamic configuration works when async_depth > 1.

* avutil/{color_utils, csp}: merge color_utils into csp and expose APILeo Izen2023-02-09
| | | | | | | | | | | | | | | | | | | | | | | | libavutil/color_utils contains some avpriv_ symbols that map enum AVTransferCharacteristic values to gamma-curve approximations and to the actual transfer functions to invert them (i.e. -> linear). There's two issues with this: (1) avpriv is evil and should be avoided whenever possible (2) libavutil/csp.h exposes a public API for handling color that already handles primaries and matricies I don't see any reason this API has to be private, so this commit takes the functionality from avutil/color_utils and merges it into avutil/csp with an exposed av_ API rather than the previous avpriv_ API. Every reference to the previous API has been updated to point to the new one. color_utils.h has been deleted as well. This should not break any applications as it only contained avpriv_ symbols in the first place, so nothing in that header could be referenced by other applications.
