wse-plugin-mediacachelocalcontent's Introduction

MediaCacheLocalContent

The MediaCacheLocalContent Media Reader is a custom IRandomAccessReader implementation for Wowza Streaming Engine™ media server software that enables you to make locally stored content available before it's transferred to a remote Media Cache source.

This repo includes a compiled version.

Prerequisites

Wowza Streaming Engine 4.0.0 or later is required.

Usage

This Media Reader can be added to new or existing on-demand (VOD) applications. It looks for the requested piece of content in an on-demand application's content storage directory first, and if it can't find it, then tries to retrieve the content from a remote Media Cache source. This is a useful function when you need to stream locally stored content alongside remote content. For example, you could use this module if you have popular content that you need to store locally or if you have content that was just recorded and you need to make it available before transferring it to the remote server.

More resources

To use the compiled version of this module, see Access content locally before trying a remote source with a Wowza Streaming Engine Java module.

wse-plugin-mediacachelocalcontent's Issues

Live support?

From what I'm reading this only enables local cache for vod applications?

I have a scenario where I want to use mediacache S3 backed scheduled streams and multibitrate stream to bind them together.

I create the usual streamschedule.smil with the schedules for mp4:amazons3/... resources. This works fine. But as I have multiple bitrates, I need to create an additional smil file with and would like to load it locally from wowza.

<smil>
        <head></head>
        <body>
                <switch>
                <video src="140e8524014871621dd046df7d7f5805_500" system-bitrate="500000"></video>
                <video src="140e8524014871621dd046df7d7f5805_1500" system-bitrate="1500000"></video>
                </switch>
        </body>
</smil>

Now, I would like to load this smil file from the content/ folder in Wowza, referencing it with smil:140e8524014871621dd046df7d7f5805.smil.

If I try to use mediacachelocalcontent to serve this file I get errors in this form:

MediaReaderH264.open[1]: java.io.IOException: MediaCacheRandomAccessReader.open: MediaCache source not permitted for this application [amazons3]: amazons3/[redacted]: java.io.IOException: MediaCacheRandomAccessReader.open: MediaCache source not permitted for this application [amazons3]: amazons3/[redacted]|at com.wowza.wms.mediacache.impl.MediaCacheRandomAccessReaderFilter.open(MediaCacheRandomAccessReaderFilter.java:77)|at com.wowza.wms.plugin.RandomAccessReaderMediaCacheLocalContent.open(RandomAccessReaderMediaCacheLocalContent.java:78)|at com.wowza.wms.mediareader.h264.MediaReaderH264.open(MediaReaderH264.java:259)|at com.wowza.wms.stream.publish.PublishingProviderMediaReader.a(PublishingProviderMediaReader.java:239)|at com.wowza.wms.stream.publish.PublishingProviderMediaReader.<init>(PublishingProviderMediaReader.java:97)|

If I don't use mediacachelocalcontent and use the default com.wowza.wms.mediacache.impl.MediaCacheRandomAccessReader
