Incorrect frame rate in video (Xuggler + MPEG 4 + H.264)

Question

I have a problem with incorrect value of frame rate in output file, after converting. I made a really simple example to describe a problem:

public static void main(String[] args) {
    // reader
    IMediaReader reader = ToolFactory.makeReader("/tmp/1/i3.avi");
    IMediaWriter writer = ToolFactory.makeWriter("/tmp/1/o3.mp4", reader);
    reader.addListener(writer);

    while (true) {
        try {
            final IError error = reader.readPacket();
            if(error != null) {
                System.err.println("Error decoding packet " + error.getDescription());

                if (!reader.isOpen()) {
                    break;
                }
            }
        } catch (final Exception ex) {
            System.err.println("Error decoding packet " + ex.getMessage());
            if (!reader.isOpen()) {
                break;
            }
        }
    }
}

Any additional parameters for video or audio streams/codecs aren't configured .

The input video file ("/tmp/1/i3.avi") has the following features:

• General
  • Container: Audio Video Interleave (AVI)
• Video
  • Dimensions: 624x352
  • Codec: XVID MPEG-4
  • Framerate: 24 frames per second
  • Bitrate: N/A
• Audio:
  • Codec: MPEG-1 Layer 3 (MP3)
  • Channels: Stereo
  • Sample rate: 48000 Hz
  • Bitrate: 112 kbps

The output video file ("/tmp/1/o3.avi") has the following features:

• General
  • Container: Quicktime
• Video
  • Dimensions: 624x352
  • Codec: H.264
  • Framerate: 8 frames per second
  • Bitrate: 378 kbps
• Audio:
  • Codec: MPEG-4 AAC
  • Channels: Stereo
  • Sample rate: 48000 Hz
  • Bitrate: 127 kbps

So, the frame rate in output file is 8 instead of 24. How can I fix it? Please, help me..

PS: I've already tried Xuggler H264 FPS encoding issue and few another solutions, it doesn't help..

UPD: After a long war with Xugler I wrote my own pure-java interface to the avconv and it works fine for me: https://github.com/vbauer/avconv4java
