@section graphmonitor, agraphmonitor
|
||||
Show various filtergraph stats.
|
||||
|
||||
With this filter one can debug complete filtergraph.
|
||||
Especially issues with links filling with queued frames.
|
||||
|
||||
The filter accepts the following options:
|
||||
|
||||
@table @option
|
||||
@item size, s
|
||||
Set video output size. Default is @var{hd720}.
|
||||
|
||||
@item opacity, o
|
||||
Set video opacity. Default is @var{0.9}. Allowed range is from @var{0} to @var{1}.
|
||||
|
||||
@item mode, m
|
||||
Set output mode, can be @var{fulll} or @var{compact}.
|
||||
In @var{compact} mode only filters with some queued frames have displayed stats.
|
||||
|
||||
@item flags, f
|
||||
Set flags which enable which stats are shown in video.
|
||||
|
||||
Available values for flags are:
|
||||
@table @samp
|
||||
@item queue
|
||||
Display number of queued frames in each link.
|
||||
|
||||
@item frame_count_in
|
||||
Display number of frames taken from filter.
|
||||
|
||||
@item frame_count_out
|
||||
Display number of frames given out from filter.
|
||||
|
||||
@item pts
|
||||
Display current filtered frame pts.
|
||||
|
||||
@item time
|
||||
Display current filtered frame time.
|
||||
|
||||
@item timebase
|
||||
Display time base for filter link.
|
||||
|
||||
@item format
|
||||
Display used format for filter link.
|
||||
|
||||
@item size
|
||||
Display video size or number of audio channels in case of audio used by filter link.
|
||||
|
||||
@item rate
|
||||
Display video frame rate or sample rate in case of audio used by filter link.
|
||||
@end table
|
||||
|
||||
@item rate, r
|
||||
Set upper limit for video rate of output stream, Default value is @var{25}.
|
||||
This guarantee that output video frame rate will not be higher than this value.
|
||||
@end table
|
||||
|
||||
@section greyedge
|
||||
A color constancy variation filter which estimates scene illumination via grey edge algorithm
|
||||
and corrects the scene colors accordingly.
