Doubts about Media Cache - VOD Edge

Wowza Streaming Engine
1

Hello friends,

I have tryed thousand times before come here. Now I need help from someone. Please!

I have a mission to access a remote server, get the files from there and then play streamming via Wowza.

I know that I have to use de Media Cache, and then use the VOD Edge application making the “link” to the source of Media Cache.

First of all I tryed access my local folder, and I couldn’t.

Bellow is my configuration and the logs:

Additional commets

I’m using “VODEdge” Application

“Storage1”, Media Cache Source

When I’m trying create the source, I have inserterd:

Prefix

path1/

Base Path

C:/Wowza/

But in validate configuration, Wowza show me:

path1/data/media/sample.mp4

C:/Wowza/data/media/sample.mp4

Even I didn’t want to have the data/media, Wowza show me that. But I created this folder in my server and Wowza still didn’t recognize my folder. I mean, I can’t play the clipe via Test Player.

I think once I can access local folder via Media cache, I will be able to access remote network drive as well.

In advance, thank you so much!

Kind regards,

Roan (becoming crazy)

Hi Roan, if content is in a sub-folder you have to specify an app instance. If the url is in the form protocol://[ip-address]/[app-name]/[stream-name].mp4 Wowza assumes that the app instance is definst and that sample.mp4 is located in the root of the content folder. If there is a part between [app-name] and [stream-name].mp4, Wowza reads that as app instance, and still looks for the [stream-name].mp4 in the root of the content folder.

So you might try a URL like this:

protocol://[ip-address]/[app-name]/_definst_/folder/sub-folder/[stream-name].mp4

Roan, I worked through this and tried to recreate the issue you are having. I was not able to recreate the issue, but instead it works for me.

So that I understand what you are doing:

You have created a folder called “Wowza” and there is a .mp4 file in this directory?

The Prefix is “path1/”

And Base Path is “C:/Wowza/”

If you open the RTMP Test Player, you should be able to view the stream with this info:

Server: rtmp://[ip-address]:1935/[app-name]/_definst_
Stream: mp4:path1/[some-file].mp4

If you are still having trouble, please refer back to this guide:

How to scale video on demand streaming with Media Cache

You will want to make sure you are following this section of the guide:

Adding a File Source

When you are ready to access the content from a remote server you well want to use the HTTP Source:

Add HTTP Source

That’s great new Roan! I am glad I could help and thanks for the update.

Salvadore,

Thank you for your answer.

I think you are talking about to run the media. But befor that, the Media Cache can’t see my Source files. This is my problem at this minute.

I’m trying access local folder, just to test, but I must access a remote server that the files .mp4 are stored.

Do you have skype?

Thank you again,

Kind regards,

Roan

Salvadore,

Thank you so much! I could access my local stream!!!

In the Test Player, was just necessary include the “path1/” on Media File Name: mp4:**path1/**sample.mp4

I have tryed change in my Media Cache from “C:/Wowza/” to “X:/Wowza/” where, “X:/” is my Network Drive mapped in my server but it didn’t works.

Do I need change the sintaxe? Can I use the IP in “Base Path”?

Do I must use HTTP in Media Cache? Because I don’t have HTTP server running in My Storage (X:/).

Once again, thank you so much!!!

Kind regards

Roan

Salvadore,

It works!!!

My base Path" is: “//10.12.80.2/Storage1/Wowza/”

Prefix: “path1”

Thank you so much!!!

Two day to put it to work!

Now I’m gonna drink some beer! :slight_smile:

Maybe in the next future I will need your help again, but in this moment I’m too much happy!

Thank you for your time and assistance!

Have a good weekends!

Roan
