Stream Alias - ModuleStreamNameAlias.nameToAlias[play]: Can't find alias entry
Hi,
I have installed Stream Alias by using http://www.wowza.com/forums/content.php?116-How-to-get-the-StreamNameAlias-AddOn method.
My aliasmap.play.txt
ppp.smil file entries
bunny.smil file entries
Errors I'm getting when I tried to play ppp.smil file
Errors I'm getting on bunny.smil file
I'm using JWplayer for the playback and I'm getting "The operation could not be completed" error
Here is my JWplayer code
Could some help me to fix this issue ?
Thanks,
Sathish

Hello there.
You cannot use alias names with .stream extension in StreamNameAlias. There is no way around that right now. Wowza treats stream names with .stream extension as aliases that resolve to the contents of the file, so you can't use them as an alias in StreamNameAlias.
Essentially, you cannot alias a .stream file because it is already aliased.
Kind regards,
Salvadore

Hello Salvadore,
I don't understand your reply. I'm not using any .stream file here. I'm using SMIL files. :confused:
Please clarify.

Hello Sathish.
You are correct, I am sorry for the confusion. I read your post to quickly and miss spoke.
I had to test this myself because I was not sure .smil files would be supported for the same reason as stated above. But it in fact does work.
The only way I was able to reproduce your error was to remove the default entry from the aliasmap.play.txt file. Please try adding this to your aliasmap.play.txt file at the bottom of the list and see if this fixes the issue:
I hope this helps.
