* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-03
| | | | | | | | It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFEAndreas Rheinhardt2022-07-18
| | | | | | | This is in preparation of switching the default init-thread-safety to a codec being init-thread-safe. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-05
| | | | | | | | | | | This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

* avcodec/codec_internal: Rename AVCodecDefault->FFCodecDefaultAndreas Rheinhardt2022-03-21
| | | | | | | This structure is no longer declared in a public header, so using an FF-prefix is more appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-21
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/nvenc: add option to disable all extra SEI dataTimo Rothenpieler2021-06-06
| | | | | | | | | | | With these triggering a lot of crashes recently, an option to globally disable all of them is added as a tool to work around those crashes in case the SEI data is not needed by the user. Also re-enables s12m for hevc_nvenc, since the issue is not specifically with that, but it affects all SEI data. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

| | | | | | | | | | | | | | | | This commit follows the same logic as 061a0c14bb, but for the encode API: The new public encoding API will no longer be a wrapper around the old deprecated one, and the internal API used by the encoders now consists of a single receive_packet() callback that pulls frames as required. amf encoders adapted by James Almer librav1e encoder adapted by James Almer nvidia encoders adapted by James Almer MediaFoundation encoders adapted by James Almer vaapi encoders adapted by Linjie Fu v4l2_m2m encoders adapted by Andriy Gelman Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec: Add explicit capability flag for encoder flushingPhilip Langdale2020-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was no way to flush an encoder such that after draining, the encoder could be used again. We generally suggested that clients teardown and replace the encoder instance in these situations. However, for at least some hardware encoders, the cost of this tear down/replace cycle is very high, which can get in the way of some use-cases - for example: segmented encoding with nvenc. To help address that use case, we added support for calling avcodec_flush_buffers() to nvenc and things worked in practice, although it was not clearly documented as to whether this should work or not. There was only one previous example of an encoder implementing the flush callback (audiotoolboxenc) and it's unclear if that was intentional or not. However, it was clear that calling avocdec_flush_buffers() on any other encoder would leave the encoder in an undefined state, and that's not great. As part of cleaning this up, this change introduces a formal capability flag for encoders that support flushing and ensures a flush call is a no-op for any other encoder. This allows client code to check if it is meaningful to call flush on an encoder before actually doing it. I have not attempted to separate the steps taken inside avcodec_flush_buffers() because it's not doing anything that's wrong for an encoder. But I did add a sanity check to reject attempts to flush a frame threaded encoder because I couldn't wrap my head around whether that code path was actually safe or not. As this combination doesn't exist today, we'll deal with it if it ever comes up.
* nvenc: implement flush to help allow an encoder to be re-usedPhilip Langdale2020-01-08
| | | | | | It can be useful to re-use an encoder instance when doing segmented encodings, and this requires flushing the encoder at the start of each segment.

* avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.

| | | | | | | | | | | | | AVCodecContext::refs is used to control the DPB size to be used by the encoder. The default value for AVCodecContext::refs as set in libavcodec/options_table.h is 1. This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in order to let the driver take the decision of the correct DPB size to use in all cases.

* avcodec/nvenc: surface allocation reductionBen Chang2017-04-26
| | | | | | | | | | | | | | | | This patch aims to reduce the number of input/output surfaces NVENC allocates per session. Previous default sets allocated surfaces to 32 (unless there is user specified param or lookahead involved). Having large number of surfaces consumes extra video memory (esp for higher resolution encoding). The patch changes the surfaces calculation for default, B-frames, lookahead scenario respectively. The other change involves surface selection. Previously, if a session allocates x surfaces, only x-1 surfaces are used (due to combination of output delay and lock toggle logic). To prevent unused surfaces, changing surface rotation to using predefined fifo. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
