Can someone help me convert this gstreamer command to C code?
>gst-launch-1.0 -e v4l2src device=/dev/video0 ! videoconvert ! queue ! tee name=t t. ! queue ! matroskamux ! queue ! filesink location=test.mkv t. ! queue ! autovideosink sync=false
I managed to almost do it myself but it produces corrupted files and I don't know how to fix that.

Lol, no. Maybe I should have been more precise. GStreamer is a library and has its own API and I want to know how to write the above command using that API. Also, GStreamer provides its own function for calling gst-launch-1.0 from code if it's needed (but I don't want that) so you shouldn't use system() even if you wanted to execute that command (which is, again, something I don't want, I want to do this by creating pipeline and the elements manually, adding elements to the pipeline, linking them and playing the pipeline).

Pastebin maybe?
I'm amateur in C and have never used gstreamer directly, but there's no problem patience can't solve. Patience and a lot of manpages

Thanks for your concern anon.
I have the code but since I've mostly finished this (still not completely, though I'm there) do you know why the program hangs when I try to send EOS to pipeline that looks like this:
> /-> queue -> autovideosink
>v4l2src -> videoconvert -> queue -> tee
> \-> queue -> valve -> matroskamux -> queue -> filesink
> alsasrc -> audioconvert -> queue -> valve /
If I send EOS to the pipeline without the last line (without the audio part) everything works fine. If the audio part is there the program hangs when it tries to send EOS.

Waiting for EOS from the audio stream? Just a wild guess, sorry if it's stupid

I'm waiting for EOS on the entire pipeline, I don't think it's possible to wait on just one element.

You're a few years late, but thanks anyway.

He means your matroskamux is waiting for an EOS from both its inputs.

So you mean that I should send EOS to both sink pads of matroskamux instead of sending EOS to the entire element matroskamux?
That may work, I'll try it. Thanks.
