* lavc/encode: add an encoder-specific get_buffer() variantAnton Khirnov2022-05-11
| | | | | | | | | | | Several encoders (roqvideo, svq1, snow, and the mpegvideo family) currently call ff_get_buffer(). However this function is written assuming it is called by a decoder. Though nothing has been obviously broken by this until now, that may change in the future. To avoid potential future issues, introduce a simple encode-specific wrapper around avcodec_default_get_buffer2() and enforce its use in encoders.

| | | | | | | | | | 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: set correct return value in ff_mpeg_ref_picturePan Bian2017-11-28
| | | | | | | | | | In function ff_mpeg_ref_picture(), it returns 0 on the error path that the return value of av_buffer_ref() is NULL. 0 indicates success, which seems to deviate from the fact. Set ret to AVERROR(ENOMEM) to propagate the error status to the callers. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec: Don't assume separate u and v planes in ff_alloc_picturePhilip Langdale2017-11-14
| | | | | | | | | | | | alloc_frame_buffer in ff_alloc_picture asserts that the linesize of planes 1 and 2 are the same. If the pixfmt has a single uv plane, like NV12, this won't be true. So, let's only do this check if there are more than 2 planes. We never hit this with previous hw formats because they don't set linesize to meaningful values, but the cuda hw format sets the values based on the underlying data layout.

| | | | | | | | | | | | | | | | | | | | | | These field are difficult to interpret, and are provided by a single encoder (mpegvideoenc). In general they do not belong to a structure containing raw data only, so remove them from AVFrame. Mpegvideoenc now uses a private field in Picture for its internal computations.
