On iPhones running iOS 11, if a video is pre-recorded and uploaded I get the following errors:- ( ie, the video is recoded on the iPhone and then uploaded as an attachment ).
$ ./ffmpeg -i <input-file>.mov -vcodec h264 -acodec mp4 test-output.mp4 FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard Mac OSX universal build for ffmpegX configuration: --enable-memalign-hack --enable-mp3lame --enable-gpl --disable-vhook --disable-ffplay --disable-ffserver --enable-a52 --enable-xvid --enable-faac --enable-faad --enable-amr_nb --enable-amr_wb --enable-pthreads --enable-x264 libavutil version: 49.0.0 libavcodec version: 51.9.0 libavformat version: 50.4.0 built on Apr 15 2006 04:58:19, gcc: 4.0.1 (Apple Computer, Inc. build 5250) [mov,mp4,m4a,3gp,3g2,mj2 @ 0x5597b8]mov: header not found !!!

If I use a ‘live’ recording then all is OK. I found this… https://www.howtogeek.com/327689/how-to-make-your-iphone-use-jpg-and-mp4-files-instead-of-heif-and-hevc/ <https://www.howtogeek.com/327689/how-to-make-your-iphone-use-jpg-and-mp4-files-instead-of-heif-and-hevc/> Which seems to suggest iOS 11 will use different formats, but this appears to make no difference whatever the settings are for ‘High Efficiency / Most Compatible’. My experience is that it’s iOS 11 devices which are causing this issue. Any ideas ?
