When I want to load the former listed mp4 files, the app will crash. In the meanwhile, I cound load other mp4 files successfully. These two files could be played without any problem with mpv or ffplay. I wonder that is the reason this issue.

I use EIRTeam.FFmpeg 1.0.4 with Godot 4.3 stable on a MacOS。

The crash info listed as follows. Could anybody take a look to these two mp4 files ?

 ERROR: Caller thread can't call this function in this node (/root). Use call_deferred() or call_thread_group() instead.

The reason for the crash is likely that the file has a second stream that is unrecognized by ffmpeg, this can be shown with ffprobe:
