Hi!
I am trying to stream a file which I donwloaded from a eVTR IMX machine.

The file should be an MPEG4 wrapped into MXF.

I receive from the player this error:

Server cannot render this media source
Extended error: Cannot render the file. The format is not supported.


What type of error is it?

Is it a client codec error or a server error?
Is this format supported?

Thank you!

Regards,
Camillo

This is server error, which one can clearly see from the message.
MXF format is not supported because your server machine does not have DirectShow MXF splitter installed. If you happen to find and install the splitter server should be able to stream MXF files.

So... I am a little bit confused Confused

You always stated the server is codec agnostic...
Not to install codecs on the server machine.
Why do I have to install the MXF splitter?

How is the story?
Could you please be more specific?

Thank you!

Regards,
Camillo

Yes you do not need decoders on the server side.
But you do need DirectShow splitter components, which can demultiplex container formats to exctract individual streams from it.

So if you have any MXF-related DirectShow package, install it on the server side; it will install the splitter too.

I installed the Sony codecs on the machine, but the message is still the same.

Look here for the graph:

Any ideas?

Thank you!

Can you play MXF files on streaming machine with Microsoft Media Player?

What a strange behaviour... Windows media Player does not play the file.
I have to build the graph manually to play the file.

Don't you have some custom configuration file to tell the server which filters to use?

Or do you have any idea?

Thank you!

If WMP cannoty play the files your MXF filters are not 100% DirectShow compliant or registered incorrectly with DirectShow.

We don't provide configuration that would allow you to choose filters or build the graph on either server or client side.
