Playing next file after another

[Sakurazuka]

Hi.

In my pipeline mixing music with input from microphone. I have queue of file paths. I want to open next file after first is finished. How should I do that?

I'm using filesrc. Even when I set pipeline to Ready or Null after first track I got the same warning:

** (<unknown>:5232): WARNING **: Changing the `location' property on filesrc when a file is open is not supported.

How should I close file then?

You should intercept the "about-to-finish" signal and change the URI in the event handler.  I don't have any working example at hand, but I'm pretty sure you should be able to find one after a few minutes of googling.

Sorry I come intho this conversation, but I had a similar problem. I got an error when I did it with video files, it advices me that I can't change the state of the pipeline. I tryed to pause and set play after setting the URI, but then I got a segmentation faul error.
Thanks

You should intercept the "about-to-finish" signal and change the URI in the
event handler.  I don't have any working example at hand, but I'm pretty

Thanks for advice, I'll check it out. Although I think changing uri may be possible only while using playbin.

If it works for you I'd like to know how you did it, thanks

if you get a segfault, then repeat running your code under gdb and paste the backtrace here.
