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

Ronald S. Bultje	e639d09199	mdec: stop preferring the simple IDCT. This was added in `e3e3c82555`, probably as a workaround for the fact that the quant table was not permutated and the IDCT coefficients are, meaning that you'd only get correct reconstruction if the IDCT permutation was an identity matrix, which happens to be the case when you use the simple IDCT. The quant table permutation bug was fixed in `42dd1434bf`, meaning this workaround is no longer necessary. In practical terms, before `42dd1434bf`, the PSNR between decodes of the fate-mdec using simple (C) or simplemmx IDCTs was 35. After `42dd1434bf`, it's 90.	8 years ago

Ganesh Ajjanagadde	2cbaa078d1	avcodec: use HAVE_THREADS header guards to silence -Wunused-function When compiled with --disable-pthreads, e.g http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7, a bunch of -Wunused-functions are reported due to missing header guards around threading related functions.
