  • calling to ffmpeg executable that the user has installed himself

    2 octobre 2018, par user1422101

    I want to convert an uncompressed .avi to .mp4 from my commercial application.

    What i want to do is this :

    1. show instructions to the user to download and install ffmpeg to a specific location
    2. create and use ffmpeg.exe to compress my .avi to .mp4

    Am i allowed (license wise) to do this ?

    Note :
    I checked https://www.ffmpeg.org/legal.html, but it doesn’t cover this.

  • Adding watermark bitmap over video in android : 4.3's MediaMuxer or ffmpeg

    7 avril 2017, par Alin

    Here is my scenario :

    • Download an avi movie from the web
    • Open a bitmap resource
    • Overlay this bitmap at the bottom of the movie on all frames in the background
    • Save the video on extarnal storage
    • The video length is 15 seconds usually

    Is this possible to achieve using MediaMuxer ? Any info on the matter is gladly received

    I’ve been looking to http://bigflake.com/mediacodec/#DecodeEditEncodeTest (Thanks @fadden) and it says there :

    "Decoding the frame and copying it into a ByteBuffer with
    glReadPixels() takes about 8ms on the Nexus 5, easily fast enough to
    keep pace with 30fps input, but the additional steps required to save
    it to disk as a PNG are expensive (about half a second)"

    So having almost 1 sec/frame is not acceptable. From what I am thinking one way would be to save each frame as PNG, open it, add the bitmap overlay on it and then save it. However this would take an enormous time to accomplish.

    I wonder if there is a way to do things like this :

    1. Open video file from external storage
    2. Start decoding it
    3. Each decoded frame will be altered with the bitmap overlay in memory
    4. The frame is sent to an encoder.

    On iOS I saw that there a way to take the original audio + original video + an image and add them in a container and then just encode the whole thing...

    Should I switch to ffmpeg ? How stable and compatible is ffmpeg ? Am I risking compatibility issues with android 4.0+ devices ? Is there a way to use ffmpeg to acomplish this ? I am new to this domain and still doing research.

    Years later edit :
    Years have passed since the question and ffmpeg isn’t really easy to add to a commercial software in terms of license. How did this evolved ? Newer versions of android are more capable on this with the default sdk ?
