I’ve got a pipeline that has textoverlay elements. I want to dynamically change the text.
Easy, well no …
I thought the least intusive way might be:
gstreamer process get a signal
handler grabs semaphore
reads work to be done
continues with gstreamer code
but no such luck:
"I don't think sem_wait() is async-signal safe.” … oops
I can think of setting a call back timer function but the are probably ways unknown to me.
