* lavc: fix and extend AVCodecContext.get_format doxyAnton Khirnov2021-06-26
| | | | | | | Remove some incorrect (or at least misleading) statements, such as the formats being ordered by quality, or the first format being the native one. Neither of those are true for hardware acceleration, which is the main use of this callback.

* avcodec: Pass HDR10+ metadata to packet side data in VP9 encoderMohammad Izadi2021-06-24
| | | | | | | | | | | | | HDR10+ metadata is stored in the bit stream for HEVC. The story is different for VP9 and cannot store the metadata in the bit stream. HDR10+ should be passed to packet side data an stored in the container (mkv) for VP9. This CL is taking HDR10+ from AVFrame side data in libvpxenc and is passing it to the AVPacket side data.

* avcodec/ccaption_dec: Make real-time latency configurablePavel Koshevoy2021-06-18
| | | | | | | | | | | Un-hardcode the 200ms minimum latency between emitting subtitle events so that those that wish to receive a subtitle event for every screen change could do so. The problem with delaying realtime output by any amount is that it is unknown when the next byte pair that would trigger output will happen. It may be within 200ms, or it may be several seconds later -- that's not realtime at all.

In this case, pairs of two consecutive fields represents a single decoded picture and have identical 'CurrPicIdx', however, only the first field is entirely intra-coded and has the flag 'intra_pic_flag' set and the second field was resetting the flag before it was even read in the function 'cuvid_output_frame'.

| | | | | | | | | | Instead return the dictionary in the state it is at the time the error occurred.

* avcodec/frame_thread_encoder: Remove redundant memcpyAndreas Rheinhardt2021-06-08
| | | | | | | | | | In case the underlying AVCodec has no private class, the private data of both the main as well as each worker AVCodecContext is just zeroed (the codec's init function has not been called on any of them and without a private class there is no way to legitimately set anything before the aforementioned init function).

* avcodec/frame_thread_encoder: Avoid dictionariesAndreas Rheinhardt2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | avcodec_open2() allows to provide options via an AVDictionary; but it is also allowed to set options by simply setting the value of the AVCodecContext or via the AVOptions API if the codec has a private class. Any options provided via an AVDictionary have already been applied before ff_frame_thread_init(), so in order to copy all the options from the main AVCodecContext and its private context, it is enough to av_opt_copy() these options. The current code does this, but it does more: It also copies the user-provided AVDictionary and uses it for the initialization of each of the worker-AVCodecContexts. This is completely unnecessary, because said options have already been copied from the main context. Furthermore, these options were also examined to decide if frame threading should be used for huffman encoding in case this would incur nondeterminism. This is wrong, because options not set via an AVDictionary are ignored. Instead inspect the values stored in the contexts directly. (In order to maintain the current behaviour, the default value of the "non_deterministic" option has been changed to false, because the absence of an entry with said key in the AVDictionary had the consequence of disallowing nondeterminism.) Finally, the AVDictionary has been removed from the signature of ff_frame_thread_encoder_init(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/encode: Always use intermediate buffer in ff_alloc_packet2()Andreas Rheinhardt2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, ff_alloc_packet2() has a min_size parameter: It is supposed to be a lower bound on the final size of the packet to allocate. If it is not too far from the upper bound (namely, if it is at least half the upper bound), then ff_alloc_packet2() already allocates the final, already refcounted packet; if it is not, then the packet is not refcounted and its data only points to a buffer owned by the AVCodecContext (in this case, the packet will be made refcounted in encode_simple_internal() in libavcodec/encode.c). The goal of this was to avoid data copies and intermediate buffers if one has a precise lower bound. Yet those encoders for which precise lower bounds exist have recently been switched to ff_get_encode_buffer() (which automatically allocates final buffers), leaving only two encoders to actually set the min_size to something else than zero (namely aliaspixenc and hapenc). Both of these encoders use a very low lower bound that is not helpful in any nontrivial case. This commit therefore removes the min_size parameter as well as the codepath in ff_alloc_packet2() for the allocation of final buffers. Furthermore, the function has been renamed to ff_alloc_packet() and moved to encode.h alongside ff_get_encode_buffer(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/omx: Remove remnants of old preallocated buffersAndreas Rheinhardt2021-06-08
| | | | | | | | | There are no preallocated buffer packets any more; this feature only worked with the old encode API and only until said API was turned into a wrapper for the new API in 93016f5d1d280f9cb7856883af287fa66affc04c.

* avcodec/dvenc: Avoid copying packet data, allow user-supplied buffersAndreas Rheinhardt2021-06-08
| | | | | | | | | | | | When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data; this also makes it easy to allow user-supplied buffers. Only one thing needed to be changed: The earlier code relied on the buffer having been initially zeroed by av_fast_padded_malloc(), so one now needs to zero the packet at first.
