I have an audio file in .3gp format on my Android device which I wish
to upload to YouTube. I know that YouTube is a video upload site and
that I need to convert this sound file to video.
I just want an image to display all the time the audio is playing.
Google tells me there are number of tools that can help me. But I want
to do this via java code from my Android device.
Please help.
Thanks.
There are tools such as FFMPEG available for free that allow you to, essentially, mix and convert heterogenous streams. That is you can add a bitmap to a video, create video from slide shows and then add sound etc. (See a related question I asked here).
These programs can be executed from within java applications by making Runtime.exec(..) calls.
