| | | | | | | | | | | | A new option -qsv_params <str> is added, where <str> is a :-separated list of key=value parameters. Example: $ ffmpeg -y -f lavfi -i testsrc -vf "format=nv12" -c:v h264_qsv -qsv_params "TargetUsage=1:GopPicSize=30:GopRefDist=2:TargetKbps=5000" -f null - Signed-off-by: Mounika Mandava <mounika.mandava@intel.com> Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* doc/filters: mention scale2ref in replacement exampleNiklas Haas2024-05-041-1/+1
| | | | So ctrl+f "scale2ref" finds it.
* doc/filters: move scale=ref_* to correct secttonNiklas Haas2024-05-041-26/+24
| | | | | This was accidentally filed under scale_npp, instead of scale. (Why is this entire section basically duplicated anyway?)
* avfilter/scale2ref: deprecate in favor of scale=rw:rhNiklas Haas2024-05-031-73/+0
| | | | And remove it from the documentation.
* avfilter/vf_scale: add optional "ref" inputNiklas Haas2024-05-031-0/+26
| | | | | | | | This is automatically enabled if the width/height expressions reference any ref_* variable. This will ultimately serve as a more principled replacement for the fundamentally broken scale2ref. See-Also: https://trac.ffmpeg.org/ticket/10795
* avfilter/vf_scale: switch to FFFrameSyncNiklas Haas2024-05-031-2/+2
| | | | | Preliminary commit, in anticipation of adding support for multiple inputs (with proper synchronization and activate() callback).
* avformat/http: Add support for Retry-After headerDerek Buitenhuis2024-04-251-0/+5
| | | | | | | | | | | | | | | | | 429 and 503 codes can, and often do (e.g. all Google Cloud Storage URLs can), return a Retry-After header with the error, indicating how long to wait, asd either a date, or in seconds, before retrying again. If it is not respected by, for example, using our default backoff stratetgy instead, chances of success are very unlikely. Some references: * https://datatracker.ietf.org/doc/html/rfc6585 * https://datatracker.ietf.org/doc/html/rfc7231#section-7.1.3 This adds an AVOption to respect that header.

* avcodec/codec_internal: Remove FF_CODEC_CAP_ALLOCATE_PROGRESSAndreas Rheinhardt2024-04-191-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before commit f025b8e110b36c1cdb4fb56c4cd57aeca1767b5b, every frame-threaded decoder used ThreadFrames, even when they did not have any inter-frame dependencies at all. In order to distinguish those decoders that need the AVBuffer for progress communication from those that do not (to avoid the allocation for the latter), the former decoders were marked with the FF_CODEC_CAP_ALLOCATE_PROGRESS internal codec cap. Yet distinguishing these two can be done in a more natural way: Don't use ThreadFrames when not needed and split ff_thread_get_buffer() into a core function that calls the user's get_buffer2 callback and a wrapper around it that also allocates the progress AVBuffer. This has been done in 02220b88fc38ef9dd4f2d519f5d3e4151258b60c and since that commit the ALLOCATE_PROGRESS cap was nearly redundant. The only exception was WebP and VP8. WebP can contain VP8 and uses the VP8 decoder directly (i.e. they share the same AVCodecContext). Both decoders are frame-threaded and VP8 has inter-frame dependencies (in general, not in valid WebP) and therefore the ALLOCATE_PROGRESS cap. In order to avoid allocating progress in case of a frame-threaded WebP decoder the cap and the check for the cap has been kept in place. Yet now the VP8 decoder has been switched to use ProgressFrames and therefore there is just no reason any more for this check and the cap. This commit therefore removes both. Also change the value of FF_CODEC_CAP_USES_PROGRESSFRAMES to leave no gaps. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* fftools/ffmpeg_filter: implement filtergraph chainingAnton Khirnov2024-04-091-5/+53
| | | | | | | | | | This allows one complex filtergraph's output to be sent as input to another one, which is useful in certain situations (one is described in the docs). Chaining filtergraphs was already effectively possible by using a wrapped_avframe encoder connected to a loopback decoder, but it is ugly, non-obvious and inefficient.

* avutil/pix{desc,fmt}: add new matrix coefficients from H.273 v3Jan Ekström2024-04-031-0/+4
| | | | | | | | | | | | * SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi Profile 5. Profile 5 can thus now be represented in VUI as {AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084, AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma sample locations are allowed). AVCOL_TRC_SMPTE2084 should in this case be interpreted as 'PQ with reshaping'. * YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the number of bits added to a source RGB bit depth is 2 (i.e., even) and 1 (i.e., odd), respectively.
