* 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/flashsv2enc: Fix use of uninitialized valueAndreas Rheinhardt2021-01-28
| | | | | | | | | | | | | | Before 257a83b969157eb76c18158a4e503e908d8b1125, certain buffers were zero-allocated in the init function and only reallocated lateron if they turned out to be too small; now they are only allocated during init, leading to use-of-uninitialized values lateron. The same could happen before if the dimensions are big enough so that the buffers would be reallocated, as the new part of the reallocated buffer would not be zeroed (happened for 960x960). So always zero the buffers in the function designed to init them. Reviewed-by: Marton Balint <cus@passwd.hu> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/flashsv2enc: factorize updating block dimensionsMarton Balint2021-01-23
| | | | | | | | | | | | The patch changes the init function to initialize block dimensions to fixed 64x64 instead of the previously used image width/height based value. This should not cause any actual change in behaviour because block dimensions are recalculated on every keyframe in optimum_block_width() and optimum_block_height() functions and in the current code the result is always 64x64 regardless of the image dimensions used.
