ffmpeg/ffserver does not crop video before streaming
Posted: Thu Jan 28, 2021 12:13 am
I'm getting the h264 video from IP camera. I need to crop it and retranslate with ffserver for viewing in zoneminder. Here is ffserver's config:
Launching ffserver:
Here is the ffmpeg command:
The video is shown in Zoneminder, but not cropped, however the size is reduced.
I've tried to record video with these parameters:
This video is recorded and played without problems and it is cropped, as it should be.
How to crop the video before sending it to stream?
