* avcodec/pnmenc: Avoid intermediate buffer, allow user-supplied buffersAndreas Rheinhardt2021-05-23
| | | | | | | | | | | For all p*m encoders a very sharp upper bound for the size of the output packets is available before the packet is allocated. This can be used to avoid an intermediate buffer when encoding by using ff_get_encode_buffer() instead of ff_alloc_packet2() (without min_size); this also adds support for user-supplied buffers.

* avcodec/jpeglsenc: Avoid intermediate buffer, allow user-supplied buffersAndreas Rheinhardt2021-05-15
| | | | | | | | | | | | | | | | | | | Up until now, the JPEG-LS encoder allocated a worst-case-sized packet at the beginning of each encode2 call; then it wrote the packet header into its destination buffer and encoded the actual packet data; said data is written into another worst-case-sized buffer, because it needs to be escaped before being written into the packet buffer. Finally, because the packet buffer is worst-case-sized, the generic code copies the actually used part into a fresh buffer. This commit changes this: Allocating the packet and writing the header into it is deferred until the actual data has been encoded and its size is known. This gives a good upper bound for the needed size of the packet buffer (the upper bound might be 1/15 too large) and so one can avoid the implicit intermediate buffer and support user-supplied buffers by using ff_get_encode_buffer().
