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.
Here is a simple class you can use with xuggler
ffmpeg -i input.mov -acodec libamr_nb -ar 8000 -b 120000 -vcodec h263 -ab 10.2k -ac 1 output.3gp
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)
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);
}
}
