Some MP3 files cause the jp-seek-bar to have no width #209

Closed mintsoft closed 9 years ago

mintsoft commented 10 years ago

I've got a few files which reliably cause the flash player to return 0 width for the .jp-seek-bar; I've unable to track it down to anything particular and it's reproducible with these files in O12, FF 28, Chromium 33.

Is there any known issues with the files or otherwise which would cause this? How can I assist in debugging this issue?

Many Thanks,

Do these MP3s have variable bit rate encoding?

mintsoft commented 10 years ago

Nope, 320kbit/sec CBR: ffmpeg -is output:

Flash Player can sometimes not like the meta data format created by some applications. Editing the meta data and re-saving using a player tool such as Winamp, Clementine, etc. can make an MP3 work properly in Flash Player. This has worked for me in the past when Flash Player is having a hard time determining the duration properly (when you see the duration or progress bar acting funny in a player). So try that.

After that I am out of ideas.

mintsoft commented 10 years ago

@kenmcd I see, so from your explorations the problem is always with the flash player?

kenmcd commented 10 years ago

No, not always, but it is a possibility. Flash Player expects standard format meta tags. For example, Apple iTunes uses its own proprietary format which – surprise, surprise – causes problems in Flash Player. Of course Apple would never cause such problems on purpose. ;-)

What I am saying is to check the meta data as a potential cause of this issue. Make sure the MP3 file has proper ID3v2 meta tags. This fixed a similar issue with MP3 duration and playback in another Flash-based player (Dewplayer).

If that does not fix the issue then the problem is elsewhere.
