* avfilter/drawbox+drawgrid - add option to prevent overwriting of source pixelsGyan Doshi2017-12-14
| | | | | | | | | | If the user-supplied color in drawbox and drawgrid filters is non-opaque, the box & grid painting overwrites the input's pixels (including alpha). Users typically expect the alpha of the specified color to only act as a key for compositing on top of the main input. Added option allows users to select between replacement and composition. Tested and documented.

| * avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>.
