Just make a passthrough filtering (ff_filter_frame(in)), and do not map
its output
Can you elaborate a bit more as I have this code as my base code
static int filter_frame(AVFilterLink *inlink, AVFrame *frame)
{
DrawBoxContext *s = inlink-dst-priv;
int plane, x, y, xb = s-x, yb = s-y;
unsigned char *row[4];
// Detect Stationary Object
// Here I would like to dump the frame as it is no longer needed
return ff_filter_frame(inlink-dst-outputs[0], frame);
}
You do exactly that and that's all. Then ffmpeg -i foo -vf bar -f null -
There are a lot of detection only filters. volumedetect, signalstats,
blackdetect, ... just copy their behaviour

Yes but this is my problem, an example command line I need at the moment
fmpeg -i .ts -vcodec libx264 -b:v 1000k -acodec libfaac -async 1 -vf
'split [mark], detection [dontneed];delay=5, markregion
[vid];[dontneed][vid] overlay' -y -f mpegts processed.ts
What I would like
fmpeg -i .ts -vcodec libx264 -b:v 1000k -acodec libfaac -async 1 -vf
'split [mark], detection; delay=5, markregion' -y -f mpegts processed.ts
I am working on the delay filter at the moment, as i need 5 frames to detect
the block, but i need to mark all frames, including the 4 previous frames. I am
trying to get rid of the overlay as the input source could be HD.
