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 Cadhalpun	1ed7fcd42a	hqx: correct type and size check of info_offset It is used as size argument of ff_canopus_parse_info_tag, which uses it as size argument to bytestream2_init, which only supports sizes up to INT_MAX. Changing it's type to unsigned simplifies the check. Reviewed-by: Vittorio Giovara <vittorio.giovara@gmail.com> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	9 years ago
