Using FFMPEG library with iPhone SDK for video encoding
21 juin 2015, par user203349I need to encode several pictures shot by the iphone camera into a mp4 video file and I know FFMPEG can do this (the application TimeLapser and ReelMoments do it already). I plan to use this in my app iMotion (available in the appstore).
I successfully install and compile the ffmpeg for the iphone SDK with this link :
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.htmlBut now I’m stuck here in my XCode project. What should I do next to use the FFMPEG library for video encoding ? The Apple documentation about external library using is very light and I just can find any tutorial on the web wich explain how to do this.
If anybody can help me, I would be very grateful..`
Thanks

Metadata:
creation_time : 2016-01-20 09:21:08
handler_name : Core Media Data Handler
encoder : H.264I want to convert it into Android support format so that all iPhone and maximum androids can read it.
However if i convert to mpeg4 format using
ffmpeg -i vid.mp4 -s 320x320 -vcodec mpeg4 -acodec aac -strict -2 -ac 2 -ar 44100 -ab 128k output.mp4
it really degrades the quality
How can i set the ffmpeg to create atleast as close as possible quality which runs on both android and iPhone
