• Linking FFMPEG library for Android

  24 février 2016, par HARSHA HN

  Can you be requested to look into this issue ? I am trying to integrate our custom application into Teaonly’s Streaming application. But, this app compresses using H264 compression (which is required for our app). But, I have been unable to integrate FFMPEG into our solution.

  Can somebody be requested to let us know the steps in simple terms ? (I am new to NDK Android) [Experts are requested to be kind to us]

  Thanks for your time and consideration.

  (By the way, the ffmpeg has been built and the following links are sounding too complicated :

• Why do I get a black box when I tile pictures with -filter_complex tile=2x1 in FFmpeg ?

  19 juin 2016, par Mateusz Piotrowski

  As I was trying to write a script (which attempts to join two pictures eventually) using FFmpeg I came across a very weird behaviour.

  I’ve found a command in an accepted answer for the very same problem I had (How to join two image into one by ffmpeg ?) :

  ffmpeg -i a.jpg -i b.jpg -filter_complex scale=120:-1,tile=2x1 output.jpg

  • Input : a.jpg, b.jpg

    

  • Output : output.jpg

    

  What happened to the B cat ? Why is it missing from the output image ? I couldn’t find any information why tile=2x1 behaves like this.

  I want to build x265 for Android in Ubuntu so that I can use this build for ffmepg. I can’t find any document how to build or cross-compile for Android
