* avfilter: Add blue and violet noise generation filtersGeorge Boyle2017-07-19
| | | | | | | | | For the blue and violet noise, I took the pink and brown noise respectively and subtracted the offsets instead of adding them. When I eyeball the frequency spectrum of the resulting outputs it looks correct to me, i.e. the blue graph appears to be a mirror image of the pink, and the same can be said of the violet and the brown. I did not do anything else to confirm the correctness.

* libavfilter/scale2ref: Maintain main input's DARKevin Mark2017-07-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The scale2ref filter will now maintain the DAR of the main input and not the DAR of the reference input. This previous behavior was deemed counterintuitive for most (all?) use-cases. Before: scale2ref=iw/4:ow/mdar in w:320 h:240 fmt:rgb24 sar:1/1 ref w:640 h:360 fmt:rgb24 sar:1/1 out w:160 h:120 fmt:rgb24 sar:4/3 flags:0x2 SAR: ((120 * 640) / (160 * 360)) * (1 / 1) = 4 / 3 DAR: (160 / 120) * (4 / 3) = 16 / 9 (main out now same DAR as ref) Now: scale2ref=iw/4:ow/mdar in w:320 h:240 fmt:rgb24 sar:1/1 ref w:640 h:360 fmt:rgb24 sar:1/1 out w:160 h:120 fmt:rgb24 sar:1/1 flags:0x2 SAR: ((120 * 320) / (160 * 240)) * (1 / 1) = 1 / 1 DAR: (160 / 120) * (1 / 1) = 4 / 3 (main out same DAR as main in) The scale2ref FATE test has also been updated.

* libavfilter/scale: Populate ow/oh when using 0 as w/hKevin Mark2017-06-19
| | | | | | | | | | | | | | | | | | | | | | The input width and height is known at parse time so there's no reason ow/oh should not be usable when using 0 as the width or height expression. Previously in "scale=0:ow" ow would be set to "0" which works, conveniently, as "scale=0:0" is perfectly valid input but this breaks down when you do something like "scale=0:ow/4" which one could reasonably expect to work as well, but does not as ow is 0 not the real value. This change handles the 0 case for w/h immediately so the ow/oh variables work as expected. Consequently, the rest of the code does not need to handle 0 input. w/h will always be > 0 or < 0. The second explicit (int) cast ensures that ow/oh appear as integers as a user might expect when dealing with pixel dimensions. Signed-off-by: Kevin Mark <kmark937@gmail.com> Signed-off-by: Ronald S.

* vf_hwmap: Add reverse mapping for hardware framesMark Thompson2017-06-14
| | | | | | | | | | | This is something of a hack. It allocates a new hwframe context for the target format, then maps it back to the source link and overwrites the input link hw_frames_ctx so that the previous filter will receive the frames we want from ff_get_video_buffer(). It may fail if the previous filter imposes any additional constraints on the frames it wants to use as output. (cherry picked from commit 81a4cb8e58636d4efd200c2b4fec786a7e948d8b)

* vf_deinterlace_vaapi: Add support for field rate outputMark Thompson2017-06-14
