1. setFormat方法的作用 setFormat方法允许你指定要处理的媒体文件的格式。这对于处理不同编码格式的视频或音频文件非常有用。通过明确设置格式,FFmpegFrameGrabber可以正确地解析和抓取媒体数据。 2. setFormat方法的参数 setFormat方法接受一个字符串参数,该参数指定了媒体文件的格式。常见的格式包括"mp4"、"avi"、"fl...

grabber.setFormat("mp4"); grabber.start(); The same code works fine for smaller video files (< 2GB). Thanks for your help. Sounds like a problem with FFmpeg on 32-bit platforms. Could you try with that file and theffmpegcommand line tool on x86 and x86_64? If that doesn't work,...
