[gst-devel] EOS only on SIGINT and not on socket error causes file created by 'filesink' element to be invalid

[Robert Krakora]

Hello All,


When I execute this pipeline from the command line...

 gst-launch -e rtspsrc location=rtsp://192.168.1.211:8109/camera.sdp ! 
rtpmp4vdepay ! mpeg4videoparse ! mp4mux ! filesink location=myfile

...and send a SIGINT to the process I get a file that is playable because I 
specified the '-e' which indicates that EOS on shutdown.

However, if I execute the same pipeline from the command line and remove the 
RTSP server (i.e. force a socket error) the process exits without performing an 
EOS on shutdown.  A quick look at the code in "gst-launch.c" confirmed my 
suspicion that EOS on shutdown is only performed on a SIGINT.   What if my 
application has recorded valuable video data and the network goes down, does 
this mean I have lost all of that data since the file will not be viewable due 
to the absence of EOS on shutdown processing on anything that is not a SIGINT?

Thanks in advance.

Best Regards,
