* 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>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.

* doc/developer: revise mailing list sectionJim DeLaHunt2017-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Developer Documentation had instructions to subscribe to the ffmpeg-cvslog email list. But that is no longer accurate. For the purposes in this section -- review of patches, discussion of development issues -- ffmpeg_devel is the appropriate email list. Some developers may want to monitor ffmpeg-cvslog, but it is not mandatory. This is v3 of this doc, based on discussion in thread <https://ffmpeg.org/pipermail/ffmpeg-devel/2017-November/220528.html> and in response to docs Maintainer comments in <https://ffmpeg.org/pipermail/ffmpeg-devel/2017-December/221596.html>. 1. In doc/developer.texi, add a new section about ffmpeg-devel, based on existing text from ffmpeg-cvslog section regarding discussion of patches and of development issues. Reflect wording from discussion at <https://ffmpeg.org/pipermail/ffmpeg-devel/2017-November/221199.html> but with copy-editing to make wording more concise. 2. In doc/developer.texi, rewrite the ffmpeg-cvslog section to match the current usage of ffmpeg-cvslog. Some developers choose to follow this list, but it is not mandatory. There are a lot of improvements possible to the Developer Documentation page, beyond this refactoring. However, making those improvements is a much bigger and more difficult task. This change is "low hanging fruit". Signed-off-by: Jim DeLaHunt <from.ffmpeg-dev@jdlh.com> Signed-off-by: Timothy Gu <timothygu99@gmail.com>

* doc: reorganize developer.texi chapter hierarchyJim DeLaHunt2017-12-02
| | | | | | | | | | | | | | | | Previously, the Developer Documentation <ffmpeg.org/developer.html> contained a single chapter, "1. Developer Guide," with all content under that single chapter. Thus the document structure was one level deeper and more complicated than it needed to be. It differed from similar documents such as /faq.html, which have multiple chapters. Eliminate the single chapter, and promote each section underneath to chapter, and each subsection to section. Thus content and relative structure remains the same, but the overall structure is simpler. Anchors within the page remain the same.

* | lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-22
| | | | | | | | | | | | | | | | | | | | | | This was added in early 2013 and abandoned several months later; as far as I can tell, there are no external users. Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).

* | doc: Add FAQs about running in background (rev 2)Jim DeLaHunt2017-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two FAQs about running FFmpeg in the background. The first explains the use of the -nostdin option in a straightforward way. Text revised based on review. The second FAQ starts from a confusing error message, and leads to the solution, use of the -nostdin option. The purpose of the second FAQ is to attract web searches from people having the problem, and offer them a solution. Add an anchor to the Main Options section of the ffmpeg documentation, so that the FAQs can link directly there. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
