• How to mux video and audio without using FFMPEG ?

  20 janvier 2019, par Yekta Sarıoğlu

  I need to mux video(mp4) and audio(wav) into a single MP4 file on the Android platform. I don’t want to use FFMPEG due to its legal issues. I tried to do with MediaMuxer. And I used this solution as an example Muxer Example but I could not succeed and got an error failed to instantiate extractor where you set data source as a string path. I looked up for more answers but wherever I search on the Internet, all I found was FFMPEG based on solutions. I could not find any reliable answers. I hope you guys can help with it. Thanks in advance.

• How to stream multiple inputs to multiple outputs on Windows ?

  17 janvier 2019, par Samoussa Binou Mymusicisinme

  I’m used to using ffmpeg and stuff to broadcast/do testing.. but I don’t understand how iptv servers succeed at having 50+ input streams, making 50+ output streams and sharing them, as I can’t even run 3 ffmpeg commands with encoding without having the CPU crying for help...

  I’ve tried to get infos, but except Wowza that seems to do what I’m trying to understand, I don’t find any info...

  I hope that you can enlight me on understanding how this whole thing works. Also, I’d like to test it out so if you got any recommendations on how to do this, I’ll be thankful to you !

• Failed to compile x264 library for android, error description : clang:error no such file or directory

  12 janvier 2019, par Lee.Saipeng

  I use a shell script to compile the x264 library to the android platform, the architecture is armeabi-v7a,The x264 library was cloned from github。

  I am sure I have those directories,and I checked the search engine such as google,No one encountered the same situation

  cp -f $PREFIX/libx264.a $PREFIX

  The error is here
  enter image description here
  The result is that this x264 library cannot be used. Can someone help me ? thanks very much

  Ok, I generated the config.log file during the compilation of x264, I hope it is an error log file, the log content is as follows :
