Android 使用FFMPEG连接两个以上的视频
我一直在做FFMPEG，这确实不是一个容易的任务，因为我已经成功地做了一些工作。我已经完成了使用ffmpeg连接两个视频的工作，但是当涉及到两个以上的视频时，它不起作用。所以我在寻找一些命令来完成我的任务 我所做的是合并两个视频：Android 使用FFMPEG连接两个以上的视频,android,video,ffmpeg,concatenation,Android,Video,Ffmpeg,Concatenation,我一直在做FFMPEG，这确实不是一个容易的任务，因为我已经成功地做了一些工作。我已经完成了使用ffmpeg连接两个视频的工作，但是当涉及到两个以上的视频时，它不起作用。所以我在寻找一些命令来完成我的任务 我所做的是合并两个视频： String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V
