Converting Quicktime (.mov ) from iPhone to mp4
24 mars 2020, par user3094755On 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 .mov -vcodec h264 -acodec mp4 test-output.mp4

.mov: Error while opening file
$If the video is recorded and then transferred to a Desktop uploaded and then converted it works OK.
If I use a ‘live’ recording then all is OK.
I found this…
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’.
Any ideas ?

IOS streaming video from iPhone to server - ffmpeg
30 mars 2013, par DaveInSydneyI have successfully written code that captures 6 second long mp4 video segments on an iPhone 4S and uploads them to a server without losing any frames between segments. This works well however I am now trying to change the mp4 container to mpeg2 ts and then upload the ts file. I am trying to figure out how ffmpeg works but I am lost. Has anyone got a bit of sample code that takes an mp4 file as input and spits out an mpeg2 ts file.
Any help would be most appreciated.
