Intel JMedia Player

Known Problems

Version 1.3.1

The following are known bugs or deviations from the documented behavior. Unless otherwise indicated, we intend to correct these in subsequent releases.

• Under ActiveMovie 1.0, setDB() and setLevel() do not work on a Realized Player (although they work on a Prefetched Player). There are two possible workarounds for this problem:
  1. Prefetch the Player prior to calling these APIs.
  2. Install Microsoft DirectX 5.0.
• Windows 95 can hang if the browser is closed while streaming an MPEG clip over a modem connection. If this happens reboot your system.
• Reset of stop time after StopAtTime event changes the current media time. The problem occurs in the following scenario: Use setStopTime() to set a value, then start the Player. When the target stop time is reached, the StopAtTime event is sent. Next, change the stop time and restart the Player. The media time is changed immediately to the stop time and the StopAtTime event is sent. To work around the problem, reset the media time and call start().
• MPEG-1 clips may have different duration when accessed locally and remotely. The duration of the same MPEG-1 clip (obtained with the Player.getDuration() API) may be slightly different if accessed locally (using FILE protocal) and remotely (using HTTP).
• JMF Players are not serializable. This is a limitatation of the Java* Media Framework API 1.0 specification.
• Installing the Java Media Framework SDK or runtimes may fail if the Internet Explorer 4.0x ActiveDesktop is installed.  This can happen because ActiveDesktop prevents removing or replacing the JMF DLLs.  There are two workarounds for this problem:
  1. Uninstall Internet Explorer ActiveDesktop.
  2. Reboot your system, uninstall JMF, then reinstall JMF.
• When compiling Java applets that use the javax.media package, the JDK 1.0.2 compiler will give an error on the import statement (for example, "import javax.media"). To workaround this problem, the SDK installation program creates two empty subdirectories javax\media and intel\media. It includes the path to these directories in your CLASSPATH. This is only a problem during compilation. It will not affect execution of applets that use the Java media classes.
• Some Java Media Framework applications or applets may cause Symantec Cafe* 1.51 Appletviewer to crash. To work around the problem, upgrade to the latest Symantec JIT (JIT 2.0 B54 is available from Symantec). If upgrading the JIT does not fix the crash, disable the Symantec JIT. To do so, add the following line to your autoexec.bat:

    set JAVA_COMPCMD=disable

  and reboot your system.
