But now my need is converting these videos to 3GP. I googled my issue but i couldnt get any solution. How can i do this? Any help will be appreciated.


Solution

  • I suggest that you use xuggler (java wrapper library for ffmpeg). With their bundled ffmpeg you can test one of your videos with this command.

    ffmpeg -i input.mov -acodec libamr_nb -ar 8000 -b 120000 -vcodec h263 -ab 10.2k -ac 1 output.3gp
    
    Here is a simple class you can use with xuggler
    public class AnyMediaConverter {
        public void main(String[] args) {
            //assumes the following: arg0 is input file and arg1 is output file
            IMediaReader reader = ToolFactory.makeReader(args[0]);
            IMediaWriter writer = ToolFactory.makeWriter(args[1], reader);
            writer.open();
            writer.setForceInterleave(true);
            IContainerFormat outFormat = IContainerFormat.make();
            outFormat.setOutputFormat("3gp", args[1], null);
            IContainer container = writer.getContainer();
            container.open(args[1], IContainer.Type.WRITE, outFormat);
            writer.addVideoStream(0, 0, ICodec.findEncodingCodecByName("h263"), 320, 240);
            writer.addAudioStream(1, 0, ICodec.findEncodingCodecByName("libamr_nb"), 1, 8000);
            reader.addListener(writer);
            while (reader.readPacket() == null);
        }
    }
    
    If your source audio sample rate and channels are not equal you will need to add an audio resampler (also ez to do with xuggler)
