Pulseaudio record multiple xfbv screens with python
10 octobre 2020, par Eric LagardaI’m trying to do something complicated and I need some help.


I’m able to record a session (video and audio) with python using xvfb and ffmpeg.


I just want to visit a page using selenium and record the video and audio. It’s working but when I try to run multiple instances, the audio is mixing between records.


How can achieve that ? I’m using pulseaudio. I know that with alsa you can set like a interface per instance, but I don’t know how to do it.


Thanks for you support and comments.

Freeze frames at a time on videos and slow down videos
24 avril 2020, par Nguyễn TrọngSuppose I have an mp4 video with a duration of 60 seconds.



I want to freeze 1 frame at the 10th second and 40th second and then extend them to about 3 seconds.
At the same time I want to increase the speed of the video to 2 times from the 1 to 20 seconds and 2 times the video slow from 30 to 60 seconds.
The video output I received was 3 + 3 + (20 - 1) * 2 + (30 - 20) + (60-30) * 2 = 108 seconds
Is there a way to do it in one statement ?



Thank in advance and sorry for my bad english.
