* avfilter/zoompan: add in_time variableexwm2020-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the zoompan filter exposes a 'time' variable (missing from docs) for use in the 'zoom', 'x', and 'y' expressions. This variable is perhaps better named 'out_time' as it represents the timestamp in seconds of each output frame produced by zoompan. This patch adds aliases 'out_time' and 'ot' for 'time'. This patch also adds an 'in_time' (alias 'it') variable that provides access to the timestamp in seconds of each input frame to the zoompan filter. This helps to design zoompan filters that depend on the input video timestamps. For example, it makes it easy to zoom in instantly for only some portion of a video. Both the 'out_time' and 'in_time' variables have been added in the documentation for zoompan. Example usage of 'in_time' in the zoompan filter to zoom in 2x for the first second of the input video and 1x for the rest: zoompan=z='if(between(in_time,0,1),2,1):d=1' V2: Fix zoompan filter documentation stating that the time variable would be NAN if the input timestamp is unknown. V3: Add 'it' alias for 'in_time. Add 'out_time' and 'ot' aliases for 'time'. Minor corrections to zoompan docs. Signed-off-by: exwm <thighsman@protonmail.com>

* fftools/ffmpeg_filter: add -autoscale to disable/enable the default scaleLinjie Fu2020-06-18
| | | | | | | | | | | | | | | | | | | | | Currently, ffmpeg inserts scale filter by default in the filter graph to force the whole decoded stream to scale into the same size with the first frame. It's not quite make sense in resolution changing cases if user wants the rawvideo without any scale. Using autoscale/noautoscale as an output option to indicate whether auto inserting the scale filter in the filter graph: -noautoscale or -autoscale 0: disable the default auto scale filter inserting. ffmpeg -y -i input.mp4 out1.yuv -noautoscale out2.yuv -autoscale 0 out3.yuv Update docs.

* hwcontext: add av_hwdevice_ctx_create_derived_optsLynne2020-05-23
| | | | | | | | | | | | | This allows for users who derive devices to set options for the new device context they derive. The main use case of this is to allow users to enable extensions (such as surface drawing extensions) in Vulkan while deriving from the device their frames are on. That way, users don't need to write any initialization code themselves, since the Vulkan spec invalidates mixing instances, physical devices and active devices. Apart from Vulkan, other hwcontexts ignore the opts argument since they don't support options at all (or in VAAPI and OpenCL's case, options are currently only used for device selection, which device_derive overrides).
