Re: [FFmpeg-user] FFmpeg pipeline debugging

awesome, though I would also need the actual filter graph. How would I get that (assuming I’m not building/specifying filter graph in the ffmpeg command). So rephrasing the question: does ffmpeg produce an internal filter graph when user specifies a command line like below and if so how can I

[FFmpeg-user] Can't make zmq listen on anything but port 5555

Hi All I have an ex where ffmpeg using zmq listens on port . Command is only used to demonstrate opening of local port: ffmpeg -y -video_size 320x240 -i /dev/video0 -filter_complex "zmq,setpts=PTS-STARTPTS" -c:v libx264 -s 320x240 -r 25 -f mpegts /dev/null ffmpeg version

[FFmpeg-user] FFmpeg pipeline debugging

Hello, I am trying to figure out how FFmpeg command line tool chains commands and runs them behind the scene and I'm wondering if it has concept of pipeline and pipeline graphs much like Gstreamer has; For example, https://gstreamer.freedesktop.org/documentation/tutorials/basic/images/playbin.png

[FFmpeg-user] Average N frames of RTSP video for better snapshot quality?

After 7.5 years of waiting, my banana plant is finally flowering! I want to do a time-lapse capture of the flowering and fruiting process. Due to its location, the easiest way for me to get a camera out there is to use a little WyzeCam v3 with the RTSP firmware and the Wyze lamp socket.
