Convert .mov (ios7) to format playable on android 4.2.1
29 novembre 2013, par user3048419I have got an iphone with ios7 and an android with 4.2.1. I want to take a video on the iphone and then play it later on the android. I am converting (via Ubuntu 13.04) the .mov video from the iphone into an mp4 format via the following (taken from Encoding video for Android) :
avconv -i <input />.MOV -vcodec libx264 -profile:v baseline -b 500k -r 30 -vf "setsar=1:1" -acodec libvo_aacenc -ac 2 -ar 44100 -ab 128k <output>.mp4
</output>Unfortunately
<output>.mp4</output>does not seem to play on the android phone (android 4.2.1). Does anyone have any suggestions on how I can convert the .mov file into a format playable on android ? -
How do I upscale an iOS App Preview video to 1080 x 1920 ?
30 août 2016, par Benjamin ThielI 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.
