| * dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-08
| | | | | | | | | | | | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>
| * lavu: add new D3D11 pixfmt and hwcontextwm42017-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be used with the new d3d11 hwaccel decode API. With the new hwaccel API, we don't want surfaces to depend on the decoder (other than the required dimension and format). The old D3D11VA pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the decoder configuration, and thus is incompatible with the new hwaccel API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D and an index. It's simpler and compatible with the new hwaccel API. The introduced hwcontext supports only the new pixfmt. Frame upload code untested. Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* | aptx: implement the aptX bluetooth codecAurelien Jacobs2017-11-10

* | lavu/timecode: clarify error msg for timecode_rateGyan Doshi2017-11-10
| | | | | | | | | | | | | | | | | | | | | | The user-supplied value for timecode_rate in drawtext is rounded to nearest integer. So, a supplied value of 0.49 or lower is rounded to 0. This throws a misleading error message which says "Timecode frame rate must be specified". Changed message to account for values under one. Also noted supported framerates for drop TC.

| | | | | | | | | | | | This makes the currently semi-public avpriv_aac_parse_header() function private to libavcodec and adds a proper public API function to return the parts of the ADTS header required in libavformat.
| * hwcontext: Improve allocation in derived contextsMark Thompson2017-04-30
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | This only supports one device globally, but more can be used by passing them with input streams in hw_frames_ctx or by deriving new devices inside a filter graph with hwmap.

* | lavfi/paletteuse: fix to support transparencyBjorn Roche2017-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables paletteuse to identify the transparency in incoming video and tag transparent pixels on outgoing video with the correct index from the palette. This requires tracking the transparency index in the palette, establishing an alpha threshold below which a pixel is considered transparent and above which the pixel is considered opaque, and additional changes to track the alpha value throughout the conversion process. This change is a partial fix for https://trac.ffmpeg.org/ticket/4443 However, animated GIFs are still output incorrectly due to a bug in gif optimization which does not correctly handle transparency.

| * lavc: Add hwaccel_flags field to AVCodecContextwm42017-03-20
| | | | | | | | | | | | | | | | This "reuses" the flags introduced for the av_vdpau_bind_context() API function, and makes them available to all hwaccels. This does not affect the current vdpau API, as av_vdpau_bind_context() should obviously override the AVCodecContext.hwaccel_flags flags for the sake of compatibility.
| * hwcontext: Make it easier to work with device typesMark Thompson2017-03-20
| | | | | | | | | | | | 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.
