However when i test this on IOS (Iphone SE) the imagepicker seems to compress the video
first e.g. 150MB to 25MB. Which I then attempt to compress the 25MB again with above
command with params "veryfast" and 18.
The file always gets larger that the original 25mb and it takes forever to execute
(>3min). Similar behaviour is experienced when I use different params e.g. 24
and faster.
If I manually record a video the imagepicker doesn't compress it and it works
the same as android.
Does sound a bit like an imagepicker issue, not ffmpeg, but I'm not an apple
person. And data compression is often like that; if the data is
"uncompressable" you still get a new header and (re)packetized data.
As always with this list, please post the complete/untrimmed text output of
the commands, they have a wealth of debugging info.
