Recording RTSP steam with Python
6 mai 2022, par ロジャーCurrently I am using MediaPipe with Python to monitor RTSP steam from my camera, working as a security camera. Whenever the MediaPipe holistic model detects humans, the script writes the frame to a file.


i.e.


# cv2.VideoCapture(RTSP)
# read frame
# while mediapipe detect
# cv2.VideoWriter write frame
# store file



Recently I want to add audio recording support. I have done some research that it is not possible to record audio with OpenCV. It has to be done with FFMPEG or PyAudio.


I am facing these difficulities.


- 

-
When a person walk through in front of the camera, it takes maybe less than 2 seconds. For the RTSP stream being read by OpenCV, human is detected with MediaPipe, and start FFMPEG for recording, that human should have walked far far away already. So FFMPEG method seems not working for me.


-
For PyAudio method I am currently studying, I need to create 2 threads establishing individual RTSP connections. One thread is for video to be read by OpenCV and MediaPipe. The other thread is for audio to be recorded when the OpenCV thread notice human is detected. I have tried using several devices to read the RTSP streams. The devices are showing timestamps (watermark on the video) with several seconds in difference. So I doubt if I can get video from OpenCV and audio from PyAudio in sync when merging them into one single video.








Is there any suggestion how to solve this problem ?


Thanks.

Reduce cpu load when playing video
2 mai 2022, par hvlifeI'm using mpv playing video as a wallpaper on my system (Arch + swaywm), just for fun. And my question is how can I reduce cpu load (video size isn't important, they are few secends long), just because i don't have dedicated gpu, just integrated intel graphics (i7-10xxx) and beefy monitor (3440x1440).
I've tried encoding videos with diffrent encoders, and I've reduced cpu load from 70% to 16% without loosing much quality with this "command" :


ffmpeg -i [source] -c:v libx264 -profile:v baseline -r:v 24 -filter:v "crop=3440:1440" [output]



Cropping is there just because my source is 4k res.
Can I go any further, or I will be loosing to much quality ?


Thanks in advance

Playing a music on speaker,record it with ffmpeg and save as
music.mp3
in current directory.

device_speaker="alsa_output.pci-0000_09_00.6.analog-stereo.monitor"
ffmpeg -f pulse -i $device_speaker music.mp3



I turn off the speaker and play the music on my headphone,how can record it with ffmpeg ?
