FMS 3.02 late-starts mp3s with id3

Hi all,

I hope someone else has seen this!

I've found that mp3 files that have id3 tags (i.e. almost all of them) don't stream properly via FMS using rtmp.

Here's an easy way to see the issue. Go to http://jonathan.podomatic.com/ and click the "Play" button at Episode 17. It will play properly. Then try the same thing with Episode 16. Episode 16 is the exact same media file, but 17 has no id3 tag and 16 has one.

We're using the sample "vod" application for streaming using RTMP.

    Deeper investigation reveals that it's the id3v2 APIC frame that is causing FMS to malfunction. On media that has the APIC frame, FMS skips the first few seconds of the media on playback via RTMP. On media without the APIC frame, FMS initiates playback correctly.

    For your listening pleasure, one with the APIC and one without.

    WITHOUT the frame:

    WITH the frame:
