This is done by sending an EOS signal<br>
through the pipeline. For the gst-launch command-line tool, just add -e in<br>
the options, like<br>
gst-launch-1.0 -e appsrc name=ringbuf ! mp4mux ! filesink<br>
location=/tmp/opt/h264.mp4<br>
<br>
On a side note, I prefer MKV containers instead of MP4 because they tend to<br>
be more resistant to errors. If you don't finalize an MKV file, you can<br>
still play the video, scrubbing or other metadata isn't available. If you<br>
don't finalize the MP4 file, the file is unplayable. MKV files can still<br>
play in VLC, so you'd be good there. <br>
<br>
Example:<br>
gst-launch-1.0 -e appsrc name=ringbuf ! matroskamux ! filesink<br>
location=/tmp/opt/h264.mkv<br>
<br>
You might need a parser right before the matroskamux, like h264parse.<br>
