Thanks for the reply
I tried as shown below ffmpeg -i rtsp://192.168.0.160:554/stream -f matroska -async 1 -vsync 1 -vcodec copy -acodec copy /mnt/sd2/sync1.mkv But still the same issue. I even tried flush_packets but no use, ffmpeg -i rtsp://192.168.0.160:554/stream -f matroska -flush_packets 1 -vcodec copy -acodec copy /mnt/sd2/sync1.mkv ________________________________ From: ffmpeg-user <[email protected]> on behalf of Carl Eugen Hoyos <[email protected]> Sent: Thursday, June 21, 2018 6:10:36 PM To: FFmpeg user questions Subject: Re: [FFmpeg-user] FFmpeg save livestream issue 2018-06-21 14:37 GMT+02:00, ashas <[email protected]>: > I am running FFMPEG on ARM based board (booting from SD card). > I have cross compiled ffmpeg source and the binaries are place in > SD card. > > I wanted to save the RTSP live stream to a video file and below is > the command used on ARM target > > *ffmpeg -i rtsp://192.168.0.160:554/stream -f matroska > -vcodec copy -acodec copy /mnt/sd2/sample2.mkv* Complete, uncut console output missing. > This command generates the video file and I am able to play it. > The issue I am facing is the time duration of output file.
