* add libaribb24 ARIB STD-B24 caption decoderJan Ekström2019-02-10
| | | | | | | | | | | | | | | | | | | | | | | | * Outputs ASS lines with basic coloring and font scaling for each given region. * Sets the default style to the resolution of the subtitle plane (for example, 960x540 / 36pt font for profile A). * Has options to: * Disable ruby text (which is coded as regions which have half-height text in libaribb24). Enabled by default as without positioning ruby text only confuses as it is usually coded in the beginning of the decoded subtitle line. * Set the working directory, in which libaribb24 will read configuration as well as into which it may save broadcast extra symbols as PNG. Unset by default. The unconventional library check can be explained by the library's current master branch being licensed as LGPLv3, but at the time of writing the latest official release is still licensed under GPLv3. Thus, one either has to wait for the following release, or enable GPLv3.

* vaapi_encode_h265: Ensure that ref pics are always in the RPSMark Thompson2019-01-27
| | | | | | | | | | | | When making a new P-frame when B-frames are present the previous P-frame is normally in the DPB because it will be referred to by subsequent B-frames. However, this is not true if there are no B-frames, or in edge cases where a GOP ends with two P-frames. Fix this by adding the direct ref pics to the RPS explicitly. Fixes #7699.

* avcodec/vp6: select idct based (loosely) on number of coefficients decodedPeter Ross2019-01-26
| | | | | | | | | | | The VP3/4/5/6 reference decoders all use three IDCT versions: one for the DC-only case, another for blocks with more than 10 coefficients, and an optimised one for blocks with up to 10 AC coefficents. VP6 relies on the sparse 10 coefficient version, and without it, IDCT drift occurs. Fixes: https://trac.ffmpeg.org/ticket/1282 Signed-off-by: Peter Ross <pross@xvid.org>

* lavc/qsvenc: enable QVBR modeZhong Li2019-01-25
| | | | | | | | | | | | | | | | | QVBR mode is to use the variable bitrate control algorithm with constant quality. mfxExtCodingOption3 should be supported to enable QVBR mode. It is neccesary to specify a max_rate for QVBR, else it may be ICQ mode. Example usage: ffmpeg -hwaccel qsv -c:v h264_qsv -i input.mp4 -c:v h264_qsv -global_quality 25 -maxrate 2M test_qvbr.mp4 -v verbose Clip QVBR quality range to be [0, 51] as Mark's commments.

* vaapi_encode: Convert to send/receive APIMark Thompson2019-01-23
| | | | | | | | | | | | | This attaches the logic of picking the mode of for the next picture to the output, which simplifies some choices by removing the concept of the picture for which input is not yet available. At the same time, we allow more complex reference structures and track more reference metadata (particularly the contents of the DPB) for use in the codec-specific code. It also adds flags to explicitly track the available features of the different codecs. The new structure also allows open-GOP support, so that is now available for codecs which can do it.
