* avcodec/encoders: Remove redundant setting of AV_PKT_FLAG_KEYAndreas Rheinhardt2021-09-28

* 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: Remove redundant freeing of extradata of encodersAndreas Rheinhardt2021-04-28
| | | | | | | | AVCodecContext.extradata is freed generically by libavcodec for encoders, so it is unnecessary for an encoder to do it on its own. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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.

* avcodec: Remove cumbersome way of checking for amount of bytes leftAndreas Rheinhardt2021-03-30
| | | | | | | | | | | | | Several encoders used code like the following to check for the amount of bytes left in a PutBitContext: pb->buf_end - pb->buf - (put_bits_count(pb) >> 3) Besides the fact that using the pointers directly might pose a maintainence burden in the future this also leads to suboptimal code: The above code reads all three pointers (buf, buf_ptr and buf_end), but touching buf is unnecessary and switching to put_bytes_left() automatically fixes this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| * Gather all coded_frame allocations and free functions to a single placeVittorio Giovara2015-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | | | | | This is probably not the simplest solution but as this is needed for a bugfix, simplification is left for later. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* | rename sub_hfyu_median_prediction_int16 to sub_hfyu_median_pred_int16Michael Niedermayer2014-05-29
| | | | | | | | | | | | This makes the naming more consistent with the 8bit variant Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
