I am in the same boat as Wedrownik. I am using the latest Beta with a Pro license and trying to export a video file with audio in it.
I am not sure how everything all works together, so of the many types of video file formats the only one I have found to actually show animations is when I export as a QuickTime using JPG.
In Editor I can get .ogg and .wav to work just fine, but I can't seem to export the audio in the video formats I have. I have done as much research as I can online about various aspects. Downloading several video players, video converters, and video file 'repair' software hasn't worked. I am of the impression that either there is a 'switch' within Spine itself to export Audio that I haven't turned on, or just isn't available right now.
If it is impossible to Export audio from Spine right now. What would be a good work-around to know that the audio lines-up properly with the frames of the video? Would I be able to take the animation/video in something like Flash and be able to see the frames and add audio in the same frames as it would have been in Spine and then export from there?
I haven't used Flash in several years, but I'm just trying to think of how I might be able to accomplish video with audio, if Spine doesn't allow it yet.
Please help steer me in the right direction. Also, thank you for sending me my license key that I had lost.
