Thanks for you help very much !!!


I tried to run the command alone, then for a long time the program did not return, and after using ctrl+c it reported the following error：


[libopenh264 @ 0x555582eec100] Incorrect library version loaded

I have this libprotokit.a in

Why configure does not find this library ?

iOS Recorded Video Playback on Android
1er mars 2015, par NiravI am trying to record video from iPhone device using UIImagePickerController and able to store it in MP4 format. The same video is uploaded on the Amazon S3 cloud.
When I try to play the same video on Android devices, it fails to play with an error, cannot play.
I searched forums/google and found that ffmpeg should be used to compress the video before uploading. I want to do the compression on the phone itself rather than on the server. Which is the best way to achieve this ?
Regards,
Nirav
