  • How do I upscale an iOS App Preview video to 1080 x 1920 ? [closed]

    12 avril 2024, par Benjamin Thiel

    I just captured a video of my new app running on an iPhone 6 using QuickTime Player and a Lightning cable. Afterwards I created an App Preview project in iMovie, exported it and could successfully upload it to iTunes Connect.

    



    Apple requires developers to upload App Previews in different resolutions dependent on screen size, namely :

    



      

    • iPhone 5(S) : 1080 x 1920 or 640 x 1136

      • 


    • iPhone 6 : 750 x 1334 (what I have)

      • 


    • iPhone 6+ : 1080 x 1920

      • 


    



    Obviously, 1080 x 1920 is killing two birds with one stone. I know that upscaling isn't the perfect solution, but it's meeting my needs. Since I don't own a 6+, another recording session won't do the trick.

    



    Unfortunately, iTunes Connect is extremely picky about what to accept. Here's what I tried, to no avail :

    



      

    • Handbrake, iMovie, QuickTime do not support upscaling

      • 


    • MPEG Streamclip

      • 


    • ffmpeg -i input.mp4 -acodec copy -vf scale=1080:1920 output.mp4

      • 


    



    Strangely enough, iTunes Connect keeps complaining about the wrong resolution when I try to upload the output.mp4 of ffmpeg.

    


  • ffmpeg error - unknow error from vkcache m3u8

    18 juillet 2017, par Robert Smith

    Trying to download this stream to mp4 :

    http://f4h4he.vkcache.com/secip/0/Phhz9wn3_IawaUZtvvlVOw/NjguMjQxLjg3LjE1OQ==/1500346800/hls-vod-s1/flv/api/files/videos/2016/03/15/1458006491172bd.mp4.m3u8

    I am using the following command :

    ffmpeg -user-agent "Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_0 like Mac OS X; en-us)" -i "http://f4h4he.vkcache.com/secip/0/Phhz9wn3_IawaUZtvvlVOw/NjguMjQxLjg3LjE1OQ==/1500346800/hls-vod-s1/flv/api/files/videos/2016/03/15/1458006491172bd.mp4.m3u8" -vcodec copy -acodec copy -bsf:a aac_adtstoasc output.mp4

    But am getting error from ffmpeg : "Unknown error"

    My question is what am I doing wrong or missing in the command ? Thanks.

  • corrupted HEIC tile when converting to JPEG

    27 mars 2018, par Kim Bowles Sørhus

    I’m having trouble converting a .HEIC image to a jpeg. The .HEIC file an image taken with an iphone running the latest ios public beta. I’m using the library nokia provided to parse the file and extract the image tiles from the .HEIC file, convert them to jpeg and glue them together using ffmpeg/montage.

    There is a bit too much code to paste it all into this question so i put all of it in this github repo. Its pretty self explanatory and should be runnable with just a few dependencies. They are explained in the repo’s README. This has all been done on osx btw.

    The .HEIC files contains a 8x6 grid of images(tiles) and if you put them together you get the complete image. Simply put whatever image i input the 7th tile is corrupted as shown below and i really don’t understand why. I’ve filed an issue with nokia, but the repo seems pretty dead and i don’t really expect an answer there.
