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

Fri Apr 28 18:28:49 EEST 2017

Thank you for your response,
Ive tried a lot of different parameters.

for the command line:
ffmpeg -i rtsp://admin:admin@192.168.32.228:554/live -c:v copy -movflags +faststart -f mp4 /home/equipoprueba/Desktop/outfile.mp4

The result is

 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
