  • Why is the filesize different when swapping audio tracks using ffmeg ?

    20 août 2021, par Brian

    I have a movie that I have encoded using Handbrake on a Mac a long time ago. When I encoded the movie, I put the stereo audio as track 1 and the 5.1 audio as track 2. The starting filesize is 853,320,914 bytes. Below is the data from ffprobe.

    My goal is to swap the stereo audio track with the 5.1 audio track and make the 5.1 audio track the default without having to reencode. To do this, I used the following command :

    


    ffmpeg -i "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019)_old.m4v" -map 0:v:0 -map 0:a:1 -map 0:a:0 -disposition:a:0 default -disposition:a:1 none -c copy "Annabelle - Comes Home (2019)/Annabelle - Comes Home (2019).m4v"

    


    Everything works as it should, I think anyways as I didn't get any errors...

    What I don't understand is why is the file size different ? The resulting file is larger at 854,292,790 bytes. Shouldn't the file sizes be the same since I literally just swapped tracks 0 and 1 ?

    I have an array of urls. I download them with fetch and then get blob from each response with await res.blob(). I need to concat all these blobs together to make a full video out of it, I tried to push each blob into an array and make a file new File(blobArray, "test") but the result has a gap between each blob.

    


    I've tried to save each blob as a separate file and concat them with ffmpeg -f concat -safe 0 -i text -c copy out3.mp4 and the result was perfect. So I know that my blobs are correct and the problem is how I am combining them together.

    


    This is my full code :

    Unfortunately links will expire soon but I think it is obvious what I am trying to do.

    


    So Is there any way to cancat blobs in JS and create the entire video smoothly like the ffmpeg does ?

    


    Thanks in advance.
