  • editly - Where can I get the return value after a video is created ?

    21 février 2021, par rom

    Quick question...

    


    Following along the README of editly, I managed to create videos after calling editly like this :

    


        // create video
    editly(editSpec)
        .catch(console.error);


    


    Unfortunately, I am using ExpressJS to do this and I need to send back a response when video creation completes.

    


    However, when I tried to extract any value using .then, it returns undefined :

    


        // create video
    editly(editSpec)
    .then(r => {
        console.log(`Is this undefined? Probably yes! r: `, r)
        res.json(r)
    })
        .catch(console.error);


    


    How can I accomplish this ?

header is detected (the current version just returns
    
AVERROR_INVALIDDATA)

  • Convert long video to 16:9 by blurring sides ?

    13 mai 2019, par JackChap77

    I am taking screenshots in python using selenium and want to convert them to a video. At the moment I have a black border around the top and bottom but I want it to be a blured image of the video in the background (the video is just a still image and audio)

    Used the filter from https://stackoverflow.com/a/30832903/8502422 but it returns ’invalid too big or non positive size’
