I use linux/Ubuntu system with EGL. I ran the given example./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4. Though voice could be saved, output.mp4 shown nothing but black screen. Would you mind help me to solve this problem?3q

maybe because I use CPU?

If you post your example video files somewhere, we can possibly look into why this is happening. It's possible that either 1) your ffmpeg installation or the addon is improperly configured or 2) there's some incompatibility between this plugin and the video inputs you're using. I think possibility 1 is more likely, but at least we will be able to debug this if I can confirm that the filter works for me with the same video files you're using.
