Gif creation still fails with -lavfi

[johndanek]

Unfortunately, the suggestion given in https://github.com/fluent-ffmpeg/node-fluent-ffmpeg/issues/588 did not fix the issue. It now produces a different, more vague error. (I commented on that issue, but since it was closed, I'm guessing no one got notifications about it)

The FFMPEG command being outputted is:

ffmpeg -i ./tmp0/input/trimmedFile.mp4 -i ./tmp0/input/palette.png -y -lavfi "fps=10 [x]; [x][1:v] paletteuse" ./tmp0/output/test.gif

And the error given is: Error: ffmpeg exited with code 1: Error initializing complex filters.

My code for creating the command is:

ffmpeg()
    .addInput(that.tmpDirNameInput+"/trimmedFile.mp4")
    .addInput(paletteFileName)
    .addOutputOption('-lavfi', '"fps='+that.instructions.params.fps+' [x]; [x][1:v] paletteuse"')
    .on('start', function(ffmpegCommand){
        console.log(new Date().toISOString()+" "+"Beginning gif creation:\n\t"+ffmpegCommand)
    })
    .on('end', function() {
        console.log(new Date().toISOString()+" "+"GIF created: "+that.instructions.params.filename+" complete! Check "+that.tmpDirNameOutput)
        resolve()
    })
    .on('error', function(error) {
        console.log(new Date().toISOString()+" "+"Error: "+error)
        reject(error)
    })
    .output(that.tmpDirNameOutput+"/"+that.instructions.params.filename)
    .run()

I've tried a few variations, but have yet to find a solution to be able to use -lavfi to create a gif with a palette using fluent-ffmpeg. I can provide more information if necessary.

Can you paste the full stderr output please ?

(btw don't hesitate to reopen issues when the problem is not solved)

Upon reading the error, I realize that I needed to remove the inner double quotes around the filter. It now works. Thanks for your patience!

Thanks for your patience, I'm not the one that waited 15 days to have their problem solved ;)
