  • Android Video Compression [on hold]

    10 mars 2015, par Arif Gencosmanoglu

    I am planning to build a small Android JAVA application that compresses images and videos. I did the image compression part and my .apk size is 1.5MB. However when I do the video compression part by using ffmpeg the application size goes up to 20.0MB. This library has tons of features that I am not using. I only need a simple video compression module to add.

    Is there any other video compression methods or functions that will be useful ?

    Thanks.

  • EM28xx input source, ffmpeg raspbian issue [on hold]

    19 mars 2015, par kamilw7

    I have a big problem with USB2861 video grabber connected to RPI (em28xx module).

    Grabber has two input : 0=svideo, 1=composite.

    When I use command :

    mplayer tv:// -tv device=/dev/video0:input=1

    everything works very good - I’ve got a composite stream on my screen, but I have no idea, what should I do to get this stream in ffmpeg.

    ffmpeg -f video4linux2 -i /dev/video0 use 0 input (svideo), I want to use 1 input (composite), but command :
    ffmpeg -f video4linux2 -i /dev/video0:input=1 show me an error.. (No such file or directory).

    It is possible to change input of device in ffmpeg ?
    Thanks in advance !
