Not sure, how to disable video recording completely?

[bushev]

I call the API like (video: false):

wpt.runTest(
        options.url,
        { location: 'us_east_1_Firefox', pollResults: 5, timeout: 60, video: false, private: true },
        (err, data) => {
          if (err) {
            reject(err);
            return;
          }
          resolve(data);
        }
      );

, but I stil see logs from ffmpeg like:

How to disable the video recording completely?

[pmeenan]

I don't think the node API wrapper exposes it but "disable_video=1" is what needs to be passed to completely disable video capture. Usually video=1 (or 0) just controls if video is uploaded but it is still captured and analyzed so that the video-based metrics will be available (start render, speed index, visually complete, etc). disable_video will completely disable video capture and the metrics won't be available.

Thank you for answering that!

I also found an option strict_video=1 in a settings.ini file, it disables all the video capture.
