Lagging multiple BGA file playback issue.

[parksh01]

Hello, I've been played BMS on beatoraja for a while, but there's a problem while playing multiple movie files on one bms file.
For example : G.X. - sa10 (download : https://sound.jp/lobsak/bms.html)
This bms uses multiple video files and switches frequently while playing bms.

I tried to make such bms of my own, but this leads lagging and frame drops while movie file is being switched.
This issue occured especially when the video file is H.264 codec and HD resolution, but even if it is MPEG-1 codec(like LR2), this issue occured.
I hope someday this issue is resolved
thank you!
