Error initializing filter 'gltransition'

Snappers-tv commented 6 years ago

I've managed to build ffmpeg with gltransition and I get the right ffmpeg header

The problem is that when I run your examples I get

Error initializing filter 'gltransition' Error initializing complex filters. Operation not permitted

Any ideas what's wrong?

Hmmm, can you post the ffmpeg command you're trying to run?

I've only tested it on Mac OS, so it may be a minor issue with differences on ubuntu.

I see in the configuration output, it has the --extra-libs flag specified twice, so it's possible one of them is getting overwritten, in which case maybe glew or glfw aren't being included properly?

Also note that depending on your platform, there may be slight variations in how GLEW and glfw are named (with regard to --extra-libs, above), e.g. -lglew or -lglfw3 - check pkg-config.

Also, can you try running your command with the -v debug flag which should provide more console output?

My OS is ubuntu 16.04

I'm running this command: ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4

I've tried to change to this config but I still get the error:

pkg-config --libs glew -lGLEW -lGLU -lGL

And:

pkg-config --libs glfw3 -L/usr/local/lib -lglfw3

I tried -v debug but there is no additional information about the filters

Is this on a headless ubuntu instance?

OpenGL requires either a GPU or something like xbfb+libmesa in order to run, so I'm guessing this is your issue. The gltransition filter is failing to initialize which would only happen if OpenGL isn't supported at runtime.

Check this thread to see if you have OpenGL support on your server.

Snappers-tv commented 6 years ago

Yes,

I've installed xvfb and mesa and it works!

Thanks

More tips for whom reaches here by searching.

Install xvfb: pkg install xorg-vfbserver(FreeBSD) apt install xvfb(Ubuntu)

Run xvfb: Xvfb :1 -screen 0 1280x1024x16 Execute ffmpeg-gl-transition example: env DISPLAY=:1 ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4

@Snappers-tv Can you tell how you installed above packages ? I am doing

sudo apt-get install xvfb
sudo apt-get install xorg-dev libglu1-mesa-dev

but the error prevails

Did you run Xvfb like @sutra explained?

Mine is ubuntu machine. So I installed xvfb similar to the @sutra way. When I type xvfb I get command not found

EitanGoldfrad commented 5 years ago

It's Xvfb (upper case x), read about it before you use it.

akashdexati commented 5 years ago

@EitanGoldfrad I have tried reinstalling everything; even the change is caps doesnot work for me. Can you share the basic System/Processor requirements for the setup to run ?

hey , I have same problem by using this dockerfile " https://github.com/transitive-bullshit/ffmpeg-gl-transition/blob/master/Dockerfile " I enter the container and run

apt-get install xvfb
apt-get install xorg-dev libglu1-mesa-dev

but still got
