* | hwcontext: Improve allocation in derived contextsMark Thompson2017-06-14
| | | | | | | | | | | | | | | | | | Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves. (cherry picked from commit c5714b51aad41fef56dddac1d542e7fc6b984627)
* | hwcontext: Make it easier to work with device typesMark Thompson2017-06-14
| | | | | | | | | | | | | | | | Adds functions to convert to/from strings and a function to iterate over all supported device types. Also adds a new invalid type AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value. (cherry picked from commit b7487f4f3c39b4b202e1ea7bb2de13902f2dee45)
* | hwcontext: Add device derivationMark Thompson2017-06-14
| | | | | | | | | | | | | | Creates a new device context from another of a different type which refers to the same underlying hardware. (cherry picked from commit b266ad56fe0e4ce5bb70118ba2e2b1dabfaf76ce)
* | videotoolbox: add hwcontext supportwm42017-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.

* | avcodec, avutil, avformat: remove AVOption requirement for some fieldswm42017-03-02
| | | | | | | | | | | | | | | | | | | | Allow all struct fields to be accessed directly, as long as they're public. Before this change, many fields were "public", but could be accessed via AVOption only. This meant they were effectively not public, but were present for documentation purposes, which was incredibly confusing at best.
* | AVFrame: add an opaque_ref fieldwm42017-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.

| * 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Return a channel layout and the number of channels based on the specified name. This function is similar to av_get_channel_layout(), but can also parse unknown channel layout specifications. Unknown channel layout specifications are a decimal number and a capital 'C' suffix, in order to not break compatibility with the lowercase 'c' suffix, which is used for a guessed channel layout with the specified number of channels.

* | avutil: add P016 pixel formatPhilip Langdale2016-11-22
| | | | | | | | | | | | | | | | | | P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using two bytes per component. It may, and in fact is most likely to, be used in situations where there are less than 16 bits of data. It is the responsibility of the writer to zero out any unused LSBs.
