  • Use ffmpeg on OSX Xcode Project for Mac

    25 mai 2016, par cmario

    I am planning to create a new app for personal use on my Mac that uses FFMPEG library, to store a feed from a RTSP IP camera.

    Following this official installation procedure from FFMPEG I have manage to successfully achieve the following 2 steps :

    To get ffmpeg for OS X, you first have to install ​Homebrew. If you don’t want to use Homebrew, see the section below.

    Then :
    - brew install automake fdk-aac git lame libass libtool libvorbis
    libvpx \ opus sdl shtool texi2html theora wget x264 xvid yasm

    Question :
    My question here because I am confused, is how to import a library into Xcode so I can use it in the application I am about to build for my Mac. I can see plenty of GitHub projects related to FFMPEG with IOS/Android, but none for OSX.

    All the FFMPEG commands under terminal are working fine, such as converting a video etc.

  • Video transcoding

    12 mai 2020, par avanjv

    I have successfully implemented video compression commands for android using FFmpeg with following command :

    



    ffmpeg -i input.mp4 -vf "scale=-1:height" -vcodec h264 -b:v 1000k -acodec mp3 output.mp4


    



    It reduces video file size substantially, though after compression video was not playing on some android devices, the issue was resolved by removing codec from the command

    



    ffmpeg -i input.mp4 -vf "scale=-1:height" -b:v 1000k output.mp4


    



    But the processing time is way too longer than expected.
I have found this official linkedin library for video transcoding
https://github.com/linkedin/LiTr

    



    Which can be used for changing resolution and/or bitrate of a video track(s). Has anyone used it ? I am new in this field, I couldn't figure out the methods to be used for scaling and adjusting bitrate of a video file for this lib (Litr). Any help with these methods ?
