Anton Khirnov	1f4cf92cfb	pthread_frame: merge the functionality for normal decoder init and init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).	5 years ago
Andreas Rheinhardt	a1a8815220	libavcodec: Reduce the size of some arrays This commit uses smaller types for some static const arrays to reduce their size in case the entries can be represented in the smaller type. The biggest savings came from inv_map_table in vp9.c.

Vittorio Giovara	e878ec0d47	aic: Fix decoding files with odd dimensions Normally the aic decoder finds the proper slice combination (multiple of some number less than 32) but in case of odd width, it resorts to the default values, which were actually swapped. The number of slices is modified to account for such odd width cases. CC: libav-stable@libav.org	10 years ago
