Gyan Doshi 9e029dc265 doc/filters: clarify behaviour of weights in amix 2022-08-09 13:59:29 +05:30
Fei Wang 26890b6b67 lavfi/overlay_vaapi: set defalut alpha value as 1.0 
The present default value of 0 will render the overlay video invisible.
A default of 1.0 is consistent with most common use cases.

Vignesh Venkatasubramanian aa8905a1b1 avfilter/xstack: Add support for fixed size grid 
Add a short hand parameter for making a fixed size grid. The existing
xstack layout parameter syntax gets tedious if all one wants is a
matrix like grid of the input streams. Add a grid option to the xstack
filter that simplifies this use case by simply specifying the number of
rows and columns instead of specific x/y co-ordinate for each stream.

Also updating the filter documentation to explain the new option.

Niklas Haas 2cb0cebd11 lavfi: add vf_iccdetect for parsing ICC profiles 
This filter is designed to parse embedded ICC profiles and attempt
extracting colorspace tags from them, updating the AVFrame metadata
accordingly.

This is intentionally made a separate filter, rather than being part of
libavcodec itself, so that it's an opt-in behavior for the time being.
This also gives the user more flexibility to e.g. first attach an ICC
profile and then also set the colorspace tags from it.

This makes #9673 possible, though not automatic.

Niklas Haas 5cfeaeef0c lavfi: add vf_iccgen for generating ICC profiles 
This filter is designed to specifically cover the task of generating ICC
profiles (and attaching them to output frames) on demand. Other tasks,
such as ICC profile loading/stripping, or ICC profile application, are
better left to separate filters (or included into e.g. vf_setparams).

Added option db_path allows custom path.
