* mpegvideo: use the AVVideoEncParams API for exporting QP tablesAnton Khirnov2021-01-01
| | | | | | | | | | Do it only when requested with the AV_CODEC_EXPORT_DATA_VIDEO_ENC_PARAMS flag. Drop previous code using the long-deprecated AV_FRAME_DATA_QP_TABLE* API. Temporarily disable fate-filter-pp, fate-filter-pp7, fate-filter-spp. They will be reenabled once these filters are converted in following commits.
* avcodec/mpegvideo: Don't zero-initialize unnecessarilyAndreas Rheinhardt2020-12-31
| | | | | | | mbintra_table will be memset to 1 a few lines after its allocation. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/mpegvideo: Merge ff_mpv_decode_defaults into ff_mpv_decode_initAndreas Rheinhardt2020-12-31
| | | | | | | | | | | | | These two are always called directly after each other (with the exception of the calls in mpeg_decode_init() where some irrelevant modifications of the avctx (which could just as well be done before ff_mpv_decode_defaults(), because it doesn't have a pointer to the AVCodecContext at all and therefore can't see these modifications at all) are performed in between), so merge ff_mpv_decode_defaults() in ff_mpv_decode_init().

* avcodec/mpeg: Initialize quarter_sample parameter from previous thread.Andriy Gelman2018-12-14
| | | | | | | Fixes #7410. The value of sub-pixel precision for me/mc can change during an Intra frame. In multi-threaded decoding this change is not propagated to other frame threads causing decoding artifacts. This patch initializes the sub-pixel precision parameter from previous thread, which fixes the issue. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
