如果需要使用gltransition 是否还需要编译一个支持gltransition的ffmpeg?

ffmpeg -i gl_transitions/ffmpeg-gl-transition/media/1.mp4 -i gl_transitions/ffmpeg-gl-transition/media/0.mp4 -filter_complex "[1][0]gltransition=duration=2:offset=1:source=/home/admin/.conda/envs/test/lib/python3.8/site-packages/ffmpeg/transitions/glsl/ZoomInCircles.glsl[tag0]" -map [tag0] ./a.mp4 -y -hide_banner

仓库里有编译用的 Dockerfile，建议依据命令自行编译。我以前也上传过 Docker 镜像，但比较久没更新了：

docker pull rustlekarl/ffmpeg-gltransition:latest
