Mark Thompson	4926fa9a4a	hwcontext_vaapi: Add driver quirks to the hwdevice 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.	9 years ago
Hendrik Leppkes	b7c5f88523	pixfmt: add P010 pixel format 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>	9 years ago
Martin Storsjö	82b7525173	Add an OpenH264 decoder wrapper 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>	9 years ago
Anton Khirnov	398f015f07	avconv: buffer the packets written while the muxer is not initialized	9 years ago
Anton Khirnov	32c8359093	lavc: export the timestamps when decoding in AVFrame.pts 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.	9 years ago

Martin Storsjö	db7968bff4	avio: Allow custom IO users to get labels for the output bytestream 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.

Martin Storsjö	933dec0e29	file: Add an option for following a file that is being written 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>	9 years ago
Andrey Utkin	ccea588f83	avio: Add an option 'rw_timeout' 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.

wm4	05f66706d1	lavc: introduce a new decoding/encoding API with decoupled input/output 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>	9 years ago
