  • How to change mp3 bitrate in android ?

    12 avril 2013, par Doãn Thiên Sầu

    I have a problem that need your help :

    In my project, I have a mp3 file with 320kps (it's big size). So how can I change its bitrate to lower (about 80kps).
    I know a library to do this, it's ffmpeg. But to use this library very complex in Android.

    My question is " is there another way to change mp3 bitrate that not use ffmpeg in Android ".

    Thank you for your help !

  • Is there a faster video rendering solution than using AndroidBitmap_xxx functions ?

    25 juillet 2012, par Alex

    In my native thread I have FFMpeg getting and decoding frames then putting them in a queue.

    On Java side I have a GLSurfaceView and from Renderer.onDrawFrame I'm calling into the native code passing a bitmap (that bitmap I create only once, then pass it every time).

    In the native code I get the head of the queue, copy data to the java bitmap using AndroidBitmap_xxx functions, then render that Bitmap on Java side as a texture.

    I wonder is there a faster way to render video ? Shall I do it entirely in the native code, if yes, why it will be faster ?

    Edit : I now don't copy RGB frame pixels to the locked bitmap pixels, rather I decode YUV frame directly into the locked bitmap pixels. This makes rendering significantly faster (because no unneeded memcpy anymore) still the question remains.

  • Need help understanding HTML 5 audio/video meta data use and placement

    27 juin 2012, par nicoz

    I have spent a significant amount of time researching HTML 5 audio and video, however I am stuck understanding the encoding of the meta data. It seems that in my research, using programs like Handbrake (ffmpeg) it is recommend to check of "web optimized" (There is also a similar type of setting when exporting from other types of software, like imovie). I have concluded (and correct me if I am wrong) that this has to do with moving the file's meta data to the beginning of the file. This then gives the player/browser the info it requires to play immediately without having to wait to load the entire file.

    So here is where I am confused and the question I need help with

    Does this only apply to the mp4 MOOV atom ? Or is there something similar in .ogv and .webm files ?
