Hi,

I hope you can help me.

I set the the maxchunkcount to 1 in application.xml.

Although this works for .m4v, it doesn’t seem to work for .mp3.

Converted an mp3 to .mp4 and still get more than 1 ts chunks.

Should I set the maxchunkcount size somewhere else, or specify the file extension?

Thanks for your help.

Are you following this guide?

I don’t think setting cupertinoMaxChunkCount is a good idea, you might get choppy or broken playback in iOS
