Description

I found out one of my application's user tried to open a file with this name رقص_ركادة_في_شارع_ب_باريس_😘😍😍💞(360p).mp4 and this error happened

avformat_open_input() error -2: Could not open input "/storage/emulated/0/VidMate/download/رقص_ركادة_في_شارع_ب_باريس_😘😍😍💞(360p).mp4". (Has setFormat() been called?)
org.bytedeco.javacv.FFmpegFrameGrabber.startUnsafe (FFmpegFrameGrabber.java:876)

Contributor guide

Research direction
Investigate how FFmpegFrameGrabber handles file paths with special characters (Unicode, emoji). Check if the issue is due to UTF 8 encoding not being passed correctly to FFmpeg's avformat open input. Look at existing fixes in similar projects or consider using URI encoding or converting the file path to a consistent encoding before passing to FFmpeg.
