Bodecs Bela	d723994449	avfilter/avf_concat: add next command This patch makes it possible to dinamically close the current segment and step to the next one by introducing command handling capabilities into the filter. This new feature is very usefull when working with real-time sources or live streams as source. Combinig usage with zmqsend tool you can interactively end the current segment and step to next one.

Gyan Doshi	1c76134fe3	avfilter/drawbox+drawgrid - add option to prevent overwriting of source pixels 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.	7 years ago

Mark Thompson	3650cb2dfa	lavu,lavfi,ffmpeg: Remove experimental OpenCL API 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).	7 years ago

Gyan Doshi	84556ef059	lavu/timecode: clarify error msg for timecode_rate 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. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Bjorn Roche	aba926e7d6	lavfi/paletteuse: fix to support transparency 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.
