* hwcontext_vaapi: add a quirk for the missing MemoryType attributeAnton Khirnov2016-10-02
| | | | | | The Intel binary iHD driver does not support the VASurfaceAttribMemoryType, so surface allocation will fail when using it.

* doc: escape left brace in texi2pod.pl regexJanne Grunau2016-07-10
| | | | | Unescaped literal left braces are deprecated and a warning was added in Perl 5.22.
* hwcontext_vaapi: Add driver quirks to the hwdeviceMark Thompson2016-07-02
| | | | | | | | | | | The driver being used is detected inside av_hwdevice_ctx_init() and the quirks field then set from a table of known device. If this behaviour is unwanted, the user can also set the quirks field manually. Also adds the Intel i965 driver quirk (it does not destroy parameter buffers used in a call to vaRenderPicture()) and detects that driver to set it.
* pixfmt: add P010 pixel formatHendrik Leppkes2016-07-02
| | | | | | | P010 is the 10-bit variant of NV12 (planar luma, packed chroma), using two bytes per component to store 10-bit data plus 6-bit zeroes in the LSBs. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* Add an OpenH264 decoder wrapperMartin Storsjö2016-06-28
| | | | | | | | While it is less featureful (and slower) than the built-in H264 decoder, one could potentially want to use it to take advantage of the cisco patent license offer. Signed-off-by: Martin Storsjö <martin@martin.st>
* avconv: buffer the packets written while the muxer is not initializedAnton Khirnov2016-06-25

* lavc: export the timestamps when decoding in AVFrame.ptsAnton Khirnov2016-06-21
| | | | | | | | | | | Currently it's exported as AVFrame.pkt_pts, which is also the only use for that field. The reason it is done like this is that lavc used to export various codec-specific "timing" information in AVFrame.pts, which is not done anymore. Since it is confusing to the callers to have a separate field which is used only for decoder timestamps and nothing else, deprecate pkt_pts and use just AVFrame.pts everywhere.
* hwcontext: add a QSV implementationAnton Khirnov2016-06-21

* lavc: allow using AVCodecContext.hw_frames_ctx for decodingAnton Khirnov2016-06-21
| | | | | For now it will only be used by the default get_buffer2 callback for allocating hw frames.

* avio: Allow custom IO users to get labels for the output bytestreamMartin Storsjö2016-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This allows callers with avio write callbacks to get the bytestream positions that correspond to keyframes, suitable for live streaming. In the simplest form, a caller could expect that a header is written to the bytestream during the avformat_write_header, and the data output to the avio context during e.g. av_write_frame corresponds exactly to the current packet passed in. When combined with av_interleaved_write_frame, and with muxers that do buffering (most muxers that do some sort of fragmenting or clustering), the mapping from input data to bytestream positions is nontrivial. This allows callers to get directly information about what part of the bytestream is what, without having to resort to assumptions about the muxer behaviour. One keyframe/fragment/block can still be split into multiple (if they are larger than the aviocontext buffer), which would call the callback with e.g. AVIO_DATA_MARKER_SYNC_POINT, followed by AVIO_DATA_MARKER_UNKNOWN for the second time it is called with the following data.

* file: Add an option for following a file that is being writtenMartin Storsjö2016-03-24
| | | | | | | | Using this requires setting the rw_timeout option to make it terminate, alternatively using the interrupt callback (if used via the API). Signed-off-by: Martin Storsjö <martin@martin.st>
* avio: Add an option 'rw_timeout'Andrey Utkin2016-03-24
| | | | | | | | | | | If set non-zero, this limits duration of the retry_transfer_wrapper() loop, thus affecting ffurl_read*(), ffurl_write(). As soon as one single byte is successfully received/transmitted, the timer restarts. This has further changes by Michael Niedermayer and Martin Storsjö.

* lavc: introduce a new decoding/encoding API with decoupled input/outputwm42016-03-23
| | | | | | | | | | | | | | | | Until now, the decoding API was restricted to outputting 0 or 1 frames per input packet. It also enforces a somewhat rigid dataflow in general. This new API seeks to relax these restrictions by decoupling input and output. Instead of doing a single call on each decode step, which may consume the packet and may produce output, the new API requires the user to send input first, and then ask for output. For now, there are no codecs supporting this API. The API can work with codecs using the old API, and most code added here is to make them interoperate. The reverse is not possible, although for audio it might. Signed-off-by: Anton Khirnov <anton@khirnov.net>
