* avutil: merge slice threading implementation from avcodec and avfilterMuhammad Faiz2017-07-194-1/+313
| | | | | | | | | | | | 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 Sebechlebsky2017-07-191-3/+4
| | | | | | | | | | | | | 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.

* avcodec/dca: avoid using bitstream reader in a non-standard wayfoo862017-07-184-8/+11

* avcodec/dca_core: probe extension headers directlyfoo862017-07-181-15/+16
| | | | | | | Avoid using bitstream reader in a non-standard way by directly accessing index. Use bit shifting/masking operations instead. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca_parser: avoid use of magic valuesfoo862017-07-181-3/+4
| | | | | | | Duration computation can be simplified because number of PCM blocks is only allowed to be a multiple of 8. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca_parser: export profile informationfoo862017-07-181-5/+39
| | | | | | | Permits applications to access DTS profile information without having to decode a frame. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/dtsdec: switch to common frame header parsing functionfoo862017-07-181-30/+9
| | | | | | | | | | | 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.

* avcodec: add avpriv_dca_parse_core_frame_header()foo862017-07-183-2/+111
| | | | | | | | There are 3 different places where DCA core frame header is parsed: decoder, parser and demuxer. Each one uses ad-hoc code. Add common core frame header parsing function that will be used in all places. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca: move bits per sample array to dca.cfoo862017-07-184-6/+6
| | | | | | | It will be used by the parser. This change avoids unwanted parser dependency on dcadata. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/dca: move some enumeration typedefs into headersfoo862017-07-184-55/+55

* pixdesc: Improve scoring for opaque/unknown pixel formatsMark Thompson2017-07-181-4/+12
| | | | | | | | | | | | | 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.
