ffmpeg "Error reinitializing filters!" on some webm videos

I have a dozen of webm videos I need to resize with the following:

ffmpeg -i input.webm -vf “scale=w=360:h=270:force_original_aspect_ratio=2,fps=10,crop=360:270” output.webm

I tried the command and it worked fine for some webm videos, but most of the returned the following error:

[AVFilterGraph @ 0x7fcb3db076c0] No such filter: '“scale'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
[libopus @ 0x7fcb3c10a000] 1 frames left in the queue on closing
Conversion failed!

I checked that ffmpeg still worked fine with previously successful files.
How can I get ffmpeg to work with the remaining wemb videos?

Solution

  • The issue was that after the first few files I copy pasted the command on a message app (Slack was the app I was copy/pasting on) and it changed the double quotes into something that only looks like double quotes.

    // this works
'command'
"command"
// this doesn't work
‘command’
“command”

    And that seemed to be the issue.
    Thanks to @Gyan for pointing me at the right direction!
