Simple VideoStreamPlayback causes thread panic

[funatsufumiya]

I just created VideoStreamPlayback as just simple as possible (with dummy data), causes thread error.

• code: src/lib.rs

First error shows use the "experimental-threads" feature, but when enabled it, still panic occurs when some audio IOThread interrupted.

Can you elaborate on this error? I assume the panic is different?

@Bromeon
Probably the reason of the panic is the same. But I don't know what is happening behind, maybe some audio event about video processing, while this example doesn't treat any audios or real video decoding (just template).
