• How do I build ffmpeg including x264 library for android ?

  27 septembre 2012, par user1093191

  Lots of question and answer available on the ffmpeg and android. But I did not get thing that directly address ffmpeg building with x264 library.

  Actually I want to make a movie from some still images in android.

  Still do not get any solution to resolve this problem. Some of the forum told that it can be do using ffmpeg. If I build ffmpeg after downloading from "http://bambuser.com/opensource", it works fine to decode a video file. But it does not get any codec while it try to encode still image into movie.

  That's why I try to use x264 as encoding library with ffmpeg. While I try to build it with ffmpeg it returns error.

  Could you please provide any detail step by step guide line to build ffmpeg with x264 library in windows or mac for android ?

  If any one knows anything other that can be used to make movie from still images in android please tell me the way. Your help will be highly appreciated.

  Thank you in advance for your kind response.

• Using ffplay as a C++ library ?

  20 janvier 2024, par Victor M

  I want to be able to use the functionality of ffplay as a C++ library, as opposed to a standalone command line tool. Right now in C++, I am able to call ffplay via std::system, but this isn't ideal for performance as is documented extensively here, chief of which is simply that we need to spawn new shell processes in order to execute this.

  


  My application attempts to feed in a bytestream of audio data to a media player. Running a command like cat /tmp/f.mp3 | ffplay -v 0 -nodisp -autoexit - runs smoothly but somewhat slowly/not instantaneously. I would ideally like to be able pass in a bytestream to an ffplay function or via some library that I can link directly to my application. I think ffplay is quite useful here, as it integrates ffmpeg and SDL together.

  


  Is this possible at all ? Or is the only hope to use the command line functionality ?
