* doc: use HOSTEXESUF when calling print_optionsTimo Rothenpieler2024-04-241-1/+1

* 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>

| | | | | | | | | | 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.

* avformat/rcwtdec: add RCWT Closed Captions demuxerMarth642024-04-021-0/+30
| | | | | | | | | | | | | | | RCWT (Raw Captions With Time) is a format native to ccextractor, a commonly used OSS tool for processing 608/708 Closed Captions (CC). RCWT can be used to archive the original extracted CC bitstream. The muxer was added in January 2024. In this commit, add the demuxer. One can now demux RCWT files for rendering in ccaption_dec or interop with ccextractor (which produces RCWT). Using the muxer/demuxer combo, the CC bits can be kept for processing or rendering with either tool. This can be an effective way to backup an original CC stream, including format extensions like EIA-708 and overall original presentation. Signed-off-by: Marth64 <marth64@proxyid.net>
* avformat/demux: add duration_probesize AVOptionNicolas Gaullier2024-04-022-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | Yet another probesize used to get the durations when estimate_timings_from_pts is required. It is aimed at users interested in better durations probing for itself, or because using avformat_find_stream_info indirectly and requiring exact values: for concatdec for example, especially if streamcopying above it. The current code is a performance trade-off that can fail to get video stream durations in a scenario with high bitrates and buffering for files ending cleanly (as opposed to live captures): the physical gap between the last video packet and the last audio packet is very high in such a case. Default behaviour is unchanged: 250k up to 250k << 6 (step by step). Setting this new option has two effects: - override the maximum probesize (currently 250k << 6) - reduce the number of steps to 1 instead of 6, this is to avoid detecting the audio "too early" and failing to reach a video packet. Even if a single audio stream duration is found but not the other audio/video stream durations, there will be a retry, so at the end the full user-overriden probesize will be used as expected by the user.
