Yes, to pause a stream using FFmpeg, you can use the “setpts” filter to slow down the stream to a halt.
To put it another way, you can adjust the presentation timestamps of video frames using the FFmpeg “setpts” filter. You can alter the presentation timestamps to speed up or slow down the video playback in an efficient manner. You can set the presentation timestamps to make it look as though the video has stopped when you wish to create a pause effect.
For a more thorough explanation, see this:
ffmpeg -i input_stream -vf "setpts=N/FRAME_RATE/TB" -c:a copy output_stream
- Input stream is specified using the -i option.
- -vf “setpts=N/FRAME_RATE/TB”: The presentation timestamps are altered using the “setpts” filter.
In this instance, N denotes the frame number, FRAME_RATE the video’s frame rate, and TB is the time base. You can alter the formula to regulate the video’s speed.
You can change the command to, for instance, pause the video for five seconds by doing the following:
ffmpeg -i input_stream -vf "setpts=5*PTS" -c:a copy output_stream
Within this altered command:
5*PTS slows down the video to a stop for the predetermined amount of time by setting the new presentation timestamp to five times the original value.
Remember that this method might add extra frames to keep the presentation slowed down, and the exact length of the pause will depend on the frame rate of the video.
It’s important to remember that although this technique produces a visual pause, it’s a simulated effect inside the video stream and might not offer actual interactive control similar to a conventional media player pause button.
