2021-04-27avcodec: Constify AVCodecsAndreas Rheinhardt
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.

2020-04-10pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov
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).

2014-06-16huffyuvdec: use unsafe bitstream readerChristophe Gisquet
The reader reads in chunks of 11 bits at most, and at most 3 times. The unsafe reader therefore may read 6 chunks instead of 1 in worst case, ie 8 bytes, which is within the padding tolerance. The reader ends up being ~10% faster. Cumulative effect of unsafe reading and code block swapping on 3 sequences is for 1 thread, decoding time goes from 23.3s to 19.0s.
