* 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: 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/put_bits: Fix LZW warningSteinar H. Gunderson2020-07-20
| | | | | | | | | | | lzwenc stores a function pointer to either put_bits or put_bits_le; however, after the recent change, the function pointer's prototype would depend on BitBuf. BitBuf is defined in put_bits.h, whose definition depends on whether BITSTREAM_WRITER_LE is #defined or not. For safety, we set a boolean flag for little/big endian instead, which also allows the definition to be inlined. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * Deprecate avctx.coded_frameVittorio Giovara2015-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
