[FFmpeg-user] FFmpeg save livestream issue

[ashas]

Hi,

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*

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. For example ,If I run ffmpeg
for 50 seconds and quit safely (pressed 'q' to stop) the generated *.mkv
file contains only ~20 sec video. 

Another observation is ,terminate ffmpeg and unmount the sd card where
output file is stored  then the complete 50 sec data is available. 

My understanding is I need to flush the incoming packets immediately to
output file and I don't want to umount the sd card . How to do it ?  
Kindly help me to resolve this issue.

Thanks
Asha
