Hey all!

I'm not sure if this isn't a feature (yet) or if it's simply a bug. However, I know it works with the original OBS, so I'm assuming it's one of the two. I've been trying to play a MOV file in OBS Studio (64-bit) by adding as a Media source and neither the video nor sound will play. The file itself has a transparent background (alpha channel) and works fine in the original OBS. Any suggestions?

Can you provide small sample (~500 KByte) of the file? (maybe static image, resolution 320x240, low sound bitrate, ~2 sec length etc.)

test example (v0.14.2 Studio 32bit, W7x86) works well.

Can you post a log file (add 'Video Capture Device' to the current Scene Collection to see any errors from 'Media Source' in log).

Hmm, oddly enough the test.mov works for me, too. I wonder if it has something to do with the filesize or the bpp (only two things I changed). Would you like to try the full size?

OK. It rises for me:
Code: 
error:   could not start slave clock as master clock was never started before being released or aborted
and doesn't play.

Maybe it's a bug.

By now, I can only suggest to change Audio encoder for your example video. I think it cause the problem for current OBS Studio build.

Yes! Changing the audio codec on rendering made all the difference. So the file plays fine, however, it will not play again unless the properties are opened and closed. Hide/show the source doesn't affect it playing again and I'm not sure how to fix that.

Media plays on activate (current build), if Restart playback when source becomes active is checked. 'Activate' - event rises when you switch scenes or close properties dialog with OK button.

If you switch scenes very fast (all devices in audio Mixer list not initialized yet and you switching back to previous scene) then activate not rises (video don't play) this is current issue (even with Cut scene transition).

Switching Scenes and waiting and then switching back still does not activate the video source to allow playback. I've tried waiting various amounts of time and still cannot get it to work.

Strange, I haven't such issue.

Can you add 'Video Capture Device' to the current Scene Collection (where your 'Media Source' lies). Then switch scenes few times (about 5 sec pause) and post a log from this attempt?
