* | ffmpeg: Allow "-to" on input files in addition to "-t"Vitaly _Vi Shukela2017-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For some strange reason "-t" option was only implemented for input files while both "-t" and "-to" were available for use for output files. This made extracting a range from input file inconvenient. This patch enables -to option for input so one can do ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

| * lavc: external hardware frame pool initializationwm42017-10-19
| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.

| * Remove all output devicesDiego Biurrun2017-10-13
| | | | | | | | | | | | The libavformat API is not suitable for exporting output devices as muxers. Some practical problems are e.g. lack of timing/synchronization mechanisms or interaction with output-specific features.

| * lavc: Add coded bitstream read/write support for MPEG-2Mark Thompson2017-08-20
| | | | | | | | Also enable MPEG-2 support in the trace_headers filter.
| * lavc: Add hevc_metadata bitstream filterMark Thompson2017-08-13
| | | | | | | | | | This is able to modify some header metadata found in the VPS/SPS/VUI, and can also add/remove AUDs.
| * lavc: Add h264_redundant_pps bitstream filterMark Thompson2017-08-13
| | | | | | | | | | | | | | | | | | This applies a specific fixup to some Bluray streams which contain redundant PPSs modifying irrelevant parameters of the stream which confuse other transformations which require correct extradata. A new single global PPS is created, and all of the redundant PPSs within the stream are removed.
| * lavc: Add h264_metadata bitstream filterMark Thompson2017-08-13
| | | | | | | | | | This is able to modify some header metadata found in the SPS/VUI, and can also add/remove AUDs and insert user data in SEI NAL units.
| * lavc: Add trace_headers bitstream filterMark Thompson2017-08-12
| | | | | | | | | | Supports all streams that the coded bitstream infrastructure does (currently H.264 and H.265).
| * vaapi_encode: Move quality option to common codeMark Thompson2017-08-06
| | | | | | | | | | | | | | | | | | Use AVCodecContext.compression_level rather than a private option, replacing the H.264-specific quality option (which stays only for compatibility). This now works with the H.265 encoder in the i965 driver, as well as the existing cases with the H.264 encoder.
| * imgutils: add function to clear an image to blackwm42017-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

| * 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>

| | | | | | | | | | | | | | | | | | | | | | 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.
