Not sure why you put the videoparse in there, it should not be needed.
It's only needed when reading raw unframed video from a file.

It's crashing in a different thread, you should attach gdb and get a
stack trace of all threads with 'thread apply all bt'. You can also run
it with G_DEBUG=fatal_warnings to make it abort at the warning.
