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)
