I can try and guide you @vinod jadhav, but not sure I can debug without a support ticket. I’ll need to know what version of Streaming Engine you are using and also what version of Java.

Pulling an mp3 from an S3 bucket does work, we tested it, but your mp3 may not be working properly in Engine first, did you test that first in Engine test players before MediaCache?

http://localhost:1935/vodedge/definst/mp3:{mediaCachePrefix}/{pathToYourFile}/{fileName}.mp3/playlist.m3u8

Some things to note:

• you need to specify the correct path
• you need to include the application instance
• you need to make sure the permissions are set accordingly on the S3 bucket/wse mediacache configuration

By “playable locally” I mean copy it to the WSE install content directory, and try playing it back with the default VOD application.

The file itself may just have a codec that is unsupported.

You can submit a support ticket if you can’t get it to work and we can take a closer look for you.
