| | | | | | | | | ff_h264_decode_mb_cabac() and ff_h264_decode_mb_cavlc() are very long functions. Declaring decode_chroma as const makes it clear the variable doesn't change after initialization.

* avfilter: Add blue and violet noise generation filtersGeorge Boyle2017-07-19
| | | | | | | | | For the blue and violet noise, I took the pink and brown noise respectively and subtracted the offsets instead of adding them. When I eyeball the frequency spectrum of the resulting outputs it looks correct to me, i.e. the blue graph appears to be a mirror image of the pink, and the same can be said of the violet and the brown. I did not do anything else to confirm the correctness.

| | | | | | | | | | | | | | | | | | | | | | | | Also remove pthread_cond_broadcast(progress_cond) on uninit. Broadcasting it is not required because workers are always parked when they are not in thread_execute. So it is imposible that a worker is waiting on progress_cond when uninitialized.

* avutil: merge slice threading implementation from avcodec and avfilterMuhammad Faiz2017-07-19
| | | | | | | | | | | | Rework it to improve performance. Now mutex is not shared by workers, instead each worker has its own mutex and condition variable. This reduces lock contention between workers. Also use atomic variable for counter. The interface also allows execute to run special function on main thread, requested by Ronald.

* libavformat/fifo: Fix initialization of underlying AVFormatContextJan Sebechlebsky2017-07-19
| | | | | | | | | | | | | Muxers may want to directly access filename in stored in AVFormatContext. For example in case of RTSP, the filename (url) is used by the muxer to extract parameters of the connection. These muxers will fail when used with fifo pseudo-muxer. This commit fixes this issue by passing filename from AVFormatContext of fifo pseudo-muxer to all AVFormatContext(s) of underlying muxers during initialization.

* avformat/dtsdec: switch to common frame header parsing functionfoo862017-07-18
| | | | | | | | | | | This makes probing for regular DTS more strict because more header fields are checked and values not supported by decoder are now rejected. Also fixes an issue original code had with 14-bit streams: 96 bits of header were expected, however only 84 bits were converted, which was not enough to parse LFE flag.

* pixdesc: Improve scoring for opaque/unknown pixel formatsMark Thompson2017-07-18
| | | | | | | | | | | | | Hardware pixel formats do not tell you anything about their actual contents, but should still score higher than formats with completely unknown properties, which in turn should score higher than invalid formats. Do not return an AVERROR code as a score. Fixes a hang in libavfilter where format negotiation gets stuck in a loop because AV_PIX_FMT_NONE scores more highly than all other possibilities.
