    5 août 2015, par user1767754

    I read what an Elementary Stream is on Wikipedia. A tool i am using "Live555" is demanding "H.264 Video Elementary Stream File". So when exporting a Video from a Video Application, do i have to choose specific preferences to generate a "Elementery Stream" ?

  • Looking for method to combine images to make a video through phonegap platform for android and ios

    28 novembre 2012, par Pat

    I'm looking to write an application that could combine images and then to form a video. I'm working with Phonegap framework to be available for use on Android and IOS.

    My question is what sort of process is involved to achieve this ?

    At this stage I've tried to read about ffmpeg, most of the questions existing on stackoverflow talk of having to get the source, compiling to make a series of libraries for use. With those libraries it needs to be tied in with the Android/IOS libraries ? (I notice there is an 'android.jar' with the project file in eclipse. Would it exist in there ?) Afterwards my confusion lies with how is this implemented into Phonegap. Develop a plugin ?

    Just to add, libav according to wiki, has hardware accelerated H.264 decoding whilst using x.264 for encoding for Android. How does that work ? Is this something accessed from libav libraries and then have to compiled in within the android.jar ?

    I may have confused terms in trying to describe what I do not know.

    Any help would be appreciated.
