Description

Flash MP3 Player Bug Report:

When playing the following file, the last word does not get played when using the small MP3 player.

http://www.cdlponline.org/audioFiles/99_basic.mp3

..../filter/mediaplugin/mp3player.swf?src=http://www.cdlponline.org/audioFiles/99_basic.mp3

Note that the Flash player on their page plays the file completely, so it doesn't seem to be a problem with the MP3 file or with Flash.

I ran into this problem as well, where the MP3 player cut off the end of the audio. I only changed Lines 65 & 66 in the ActionScript, and it took care of the problem, but more testing would be needed to determine if other problems were created. However, my sound files play through to the end now, which is what I needed. If this is helpful to the wider community, I'm glad to be of service.

Hi, how did you test a microsecond?
On the file given in the introduction, I can hear all well. I tested on 1.6 and 1.9

Hi Jerome. I think "microsecond" was a bit of an exaggeration...lol. The MP3 player was cutting off the last word or two, the same problem reported on this thread: http://moodle.org/mod/forum/discuss.php?d=51595; in the example given in this post (http://moodle.org/mod/forum/discuss.php?d=51595#p430679), you can hear how the entire last sentence of the MP3 is cut off by the player. This problem was caused by the original Flash coding resetting and pausing when the playhead reached the end, not when the audio was finished. I suspect there is a problem with the original coding not factoring in the buffer time, but it doesn't matter because the playhead reaching the end is not as accurate as when the audio file itself reaches the end. My code removes checking when the playhead reaches the end. Instead, the MP3 player resets and pauses when the audio file itself is finished.

Here is the Action Script diff for the Peter's patch:

if (playMode == "play") {
slider.handle._x = s.position / s.duration * slider.track._width;
// if we've reached the end of the file

  • if (Math.round(slider.handle._x) == Math.round(slider.track._width)) {
    + s.onSoundComplete = function()
    + { // reset the slider to the beginning and pause slider.handle._x = 0; pauseBtn.onPress(); }
    }

Ii looks and sounds find to me. I'll do a bit more tests and I'll commit it.

I added Peter's fix to the flash player. Note that I saved the new fla file under CS3 format. I also republished the swf file with flash CS4.
Thanks Peter for the fix

Hi,
I retested the small and big player on a fresh install of the latest 1.9, it works well.
Please if anyone has still a problem, attach the concerned mp3 to this issue and describe what's the missing words. Also indicate accurately where you display the small player. Thank you.

Dom just reported to me it was still not working. I tested, Helen retested. It could be a Flash player problem... please let me know your flash player version number. retesting with the last 1.9, I'll let you know...

Hi,
I've just tested the attached file with the big flash player, I confirm I can't hear the end of the music in a resource file (it works for the small player in a forum). It seems like the issue appears only on certain mp3. I reopen this issue.

Reassigned to nobody. Any Flash contribution will be appreciated.

If someone attach a patch, I'll review it (please comment your Flash code for a beginner ). In this case reassign the issue to me when you attach the patch. Thank you.
