SAP deletion messages
Posted: 14 Nov 2012 11:48
Hi,
I'm am currently implementing a SAP server, and using VLC as a SAP receiver to test against.
It seems to me that VLC is treating SAP deletion messages (as indicated by the flag in the first byte of the message) as further announcements, and adding another copy of the channel to the list when I'm actually trying to delete it.
I've had a quick look at the code, and it appears to ignore deletion messages as these (apparently) 'can easily be used to highjack an announcement by a third party'. However, it then appears to go on and treat the deletion message like any other announcement.
Finally, I'm sending announcements every 5 seconds, and based on my reading of the code I'd expect the stream to be removed after 15 seconds if I stop sending the announcements. However, this doesn't appear to be happening.
Can anyone offer any advice on this? Is there another 'reference' SAP receiver that I can use for testing against? I have access to both linux and Windows platforms.
Thanks
Andy
