IS-05-01 test activating Sender transport_params updates SDP file

[garethsb]

The IS0501Test.test_23 checks that Sender transport parameters are changeable, but it doesn't check that they are reflected into the SDP at the /transportfile endpoint when activated.

We need that, unless I've missed it somewhere!

If we are able to add a simple way to check SDP attributes, we should also check that media information matches between the SDP file and the IS-04 Source/Flow attributes.

Yes, absolutely! Thanks for pointing that out!!

Not sure whether to raise this as a separate issue but I discovered recently that SDPoker doesn't report any warning or error for the following file:

v=0
o=- 0 0 IN IP4 0.0.0.0
s=Empty Sdp file
c=IN IP4 0.0.0.0/127
t=0 0

Remaining items:

• Add SDP media attribute checks to IS-05-02
• Add empty SDP check to SDPoker

The final part of this should be resolved by Streampunk/sdpoker#20

Closing this as the remaining part is outside of our control.
