Error initializing complex filters

[darrinps]

This is similar to a closed issue, but the person never shared their code. I was having the same problem.

Here is what I was doing:

`

         val cmd = "-y -i $inputFileUrl -i $transparencyFullUrl -filter_complex \"[1]format=bgra,colorchannelmixer=aa=1,rotate=0:c=black@0:ow=rotw(0):oh=roth(0) 
         [overlayImage];[0][overlayImage]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2\" 
        $outputPathAndName"
    val command = cmd.split(" ".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()

    Timber.i("*** About to try FFmpeg with the following lines. ***")

    for(line in command) {
        Timber.i(line)
    }

    try {
        FFmpeg.getInstance(context).execute(command, object : ExecuteBinaryResponseHandler() {

            override fun onSuccess(s: String) {
                callback.onFinishOverlay(outputPathAndName, start, end)
            }
   ...

`

The actual text gets spit out by Timber is as follows: 2019-08-19 12:34:24.484 11669-11669/com.android.app I/VideoEditorUtil: -y 2019-08-19 12:34:24.484 11669-11669/com.android.app I/VideoEditorUtil: -i 2019-08-19 12:34:24.484 11669-11669/com.android.app I/VideoEditorUtil: /storage/emulated/0/Android/data/com.android.app/cache/trimmedVideo_20190819_123424.mp4 2019-08-19 12:34:24.485 11669-11669/com.android.app I/VideoEditorUtil: -i 2019-08-19 12:34:24.485 11669-11669/com.android.app I/VideoEditorUtil: /storage/emulated/0/Android/data/com.android.app/cache/transparency.png 2019-08-19 12:34:24.485 11669-11669/com.android.app I/VideoEditorUtil: -filter_complex 2019-08-19 12:34:24.485 11669-11669/com.android.app I/VideoEditorUtil: "[1]format=bgra,colorchannelmixer=aa=1,rotate=0:c=black@0:ow=rotw(0):oh=roth(0)[overlayImage];[0][overlayImage]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2" 2019-08-19 12:34:24.485 11669-11669/com.android.app I/VideoEditorUtil: /storage/emulated/0/Android/data/com.android.app/cache/baked_trimmedVideo_20190819_123424.mp4

The exact error is showing as:

[AVFilterGraph @ 0xf6496080] No such filter: '"' Error initializing complex filters. Invalid argument

Here is the solution for others seeing this in the future.

Just remove the \" before and after the parameters.

So the val cmd line goes to this:

                 val cmd = "-y -i $inputFileUrl -i $transparencyFullUrl -filter_complex [1]format=bgra,colorchannelmixer=aa=1,rotate=0:c=black@0:ow=rotw(0):oh=roth(0)[overlayImage];[0][overlayImage]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2 $outputPathAndName"
