| | | | | | | | | | | Currently, the AV_PKT_FLAG_KEY is automatically set for audio encoders; yet this is wrong, as both MLP and TrueHD have non-keyframes. So set it based upon AV_CODEC_PROP_INTRA_ONLY (from the corresponding AVCodecDescriptor) instead. This also sets it for some video codecs, which is intended.

* avcodec/avcodec: Make sanity check stricterAndreas Rheinhardt2021-09-26
| | | | | | | | | | | | | If an AVCodec has a private class, its priv_data_size must be > 0 and at the end of a successful call to avcodec_open2() the AVCodecContext's priv_data must exist and its first element must be a pointer to said AVClass. This should not be conditional on priv_data_size being > 0 (which is tested by FATE) or on the private context having been successfully allocated (which has to have happened at that point). So remove these preconditions to make the test stricter. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* webp: fix transforms after a palette with pixel packing.Maryla2021-09-25
| | | | | | | | | | | | | | | When a color indexing transform with 16 or fewer colors is used, WebP uses "pixel packing", i.e. storing several pixels in one byte, which virtually reduces the width of the image (see WebPContext's reduced_width field). This reduced_width should always be used when reading and applying subsequent transforms. Updated patch with added fate test.
