For testing, I modified the RTMP URL from YouTube to localhost. def testpipe(): width 32 height 32 framesize width height 3 3 bytes for rgb24 framecount 10 startframe 2 out ( ffmpeg.input( pipe:0. re argument is probably required for live streaming. Related to your question, you can as well pipe OpenCV images to FFMPEG. I opened an issue on Github, turns out it may be a platform issue. The drawback here is that ffmpeg open a whole videostream, so a consequence is that. Assuming you actually need to use OpenCV for the video, you have to add the audio directly to FFmpeg as Gyan commented, because OpenCV does not support audio. Pipe opencv images to ffmpeg using python Pipe opencv images to ffmpeg using python. So im going with a solutin i found here Handle large number of rtsp cameras without real-time constraint. My current solution is based on doing that with opencv, but i want to optimize this. Time1 = "".format(today.day, today.month, today.year, today.hour, today.minute, cond)Ĭommand = "sh -c 'ffmpeg -f pulse -nostdin -i alsa_b-FuZhou_Kingwayinfo_CO._LTD_TONOR_TC30_Audio_Device_20200707-00.mono-fallback /home/pi/sound_recorder/Recordes/'" + time1 + ".mp3" Im looking for a way to extract one single image from an rtsp stream.
