Re: [Ekiga-devel-list] Some points on the EKIGA/OPAL video plugin

[Matthias Schneider <ma30002000 yahoo de>]

Hi, 

thank you for the quick answers. First of all I would like to comment on my question about the
missing video codec in the ekiga codec list with a dynamic payload type - I tried opalcodecinfo on
a video codec with dynamic payload type and it reported everything quite fine (dynamically
assigning payload types) - so the problem must be something with the ekiga video codec list... The
only thing I did is (it can be tried out with H.261 for example) to change the RTP PT from 31 to 0
and changing the RTPTypeExplicit flag to RTPTypeDynamic.

For the other points see my comments inline..

Ok I will file an OPAL bug report...

Thank you very much, so there is no more need for further action from my part?

Ok, its not that important right now, video can be transmitted with a fixed payload size of 1400
bytes.

Ok, so what would have to be done? Where should we run the framecounter, in the plugin or in OPAL
(e.g. increase it every time a packet with a markbit is received)? Where should I look for the
interface to ekiga? Over what timeframe are the bitrate values calculated?

Ok, I will trust you on this one.
