Transcoding wmv file to mp4 using Jave

I am trying to use Jave to convert a wmv file into h264(mp4). The final version created by Jave plays fine with VLC player but when I try to use it inside the HTML5 video tag, it is not able to play the file.

I am guessing that the issue is with the attributes I am setting for the video attributes.

Java Code:

    videoAttributes.setCodec("mpeg4");
    videoAttributes.setTag("mpeg4");
    videoAttributes.setBitRate(new Integer(5000));
    videoAttributes.setFrameRate(new Integer(30));
    videoAttributes.setSize(new VideoSize(512, 384));
    encodingAttributes.setVideoAttributes(videoAttributes);
    encodingAttributes.setFormat("mp4");

HTML code:

    <video controls="true" width=400 height=200>
        <source src="path_to_converted_mp4_file" type="video/mp4" />
        Not Supported
    </video>

According to the JAVE documentation the name of the format is "mp4" not "mpeg4"

Don't know how Jave identifies codecs but if it uses the same naming as FFmpeg then the codec for HTML5 should be libx264. The mpeg4 codec is "MPEG-4 part 2" according to ffmpeg -codecs.

    ./ffmpeg -codecs | grep -e mpeg4 -e 264
     D V D  h264            H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
     EV    libx264         libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
     EV    libx264rgb      libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 RGB
     DEVSDT mpeg4           MPEG-4 part 2
     DEVSD  msmpeg4         MPEG-4 part 2 Microsoft variant version 3
     D VSD  msmpeg4v1       MPEG-4 part 2 Microsoft variant version 1
     DEVSD  msmpeg4v2       MPEG-4 part 2 Microsoft variant version 2
