When a channel formula ends with a subtraction, the next formula will
otherwise have its first coefficient negated.
(cherry picked from commit 4f4e19914d)
This is an ABI change in libva2: previously the Intel driver had this
behaviour and it was implemented as a driver quirk, but now it is part
of the specification so all drivers must do it.
Allows to specify the action to be performed when reading the last frame
from the internal FIFO buffer. By default the last frame is written to
filter output depending on the timestamp rounding method. When using
"pass" action the last frame is passed through if input duration
has not been reached yet.
Examples using an input file with 25Hz, 1.4sec duration:
- "fps=fps=1:round=near" generates an output file of 1sec
- "fps=fps=1:round=near:eof_action=pass" generates an output file of
2sec

The complex vertical low-pass filter slightly over-sharpens the picture. This becomes visible when several transcodings are cascaded and the error potentises, e.g. some generations of HD->SD SD->HD.
To prevent this behaviour the destination pixel must not exceed the source pixel when the average of the pixels above and below is less than the source pixel. And the other way around.
Tested and approved in a visual transcoding cascade test by video professionals.
SSIM/PSNR test with the first generation of an HD->SD file as a reference against the 6th generation(3 x SD->HD HD->SD):

Use the earliest input with the same status.
If that fails, print a warning and use the earliest source.
With this change, simple filter forward correctly the timestamp
of EOF.
Filters that are supposed to change it should be updated to
actually forward it.
