[FFmpeg-user] moov atom not found‏

[juha s.]

Hi

I'm capturing live h264 stream over RTSP protocol and time to time when I stop recordind I get corrupted file. 

Here is ffmpeg line what I use for recording:  ffmpeg -i rtsp://192.169.23.28:8555 -aspect 16:9 -copyts -vcodec libx264 -preset fast -b:v 900k -crf 22 -y /videos/video1.mp4 . I must stop this record using "pkill 2" (=ctrl+c) command, because I like to split this program for peaces.

Moust of files are OK and I can play those without any problem. Here is one of those working files output:

And sometimes from same source and same stream, the recording fails for " moov atom not found":

So what's the trik here or how I should do this to get all files to work without any problem ?
