[FFmpeg-user] Problem with ffmpeg command when recording live streams

[DopeLabs]

Have you tried a stream copy or only encoding the audio to mp3/aac since the video looks like its already in h264?

Stream copy video and re-encode audio

ffmpeg -I rtsp:/ip -c:v copy -c:a mp3 -b:a 128k -movflags +faststart -f mp4 outfile.mp4
