Andreas Rheinhardt	56e9e0273a	avcodec/encode: Always use intermediate buffer in ff_alloc_packet2() 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>	4 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs 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.
