[vlc-devel] [RFC] stream output MTU

[Rémi Denis-Courmont]

	Hello,

Currently, we have a default "MTU" of 1500 bytes in a few places in the 
stream output stuff. As far as I understand, that "MTU" represent the 
UDP payload size, including the potential RTP header, but excluding 
transport and network header, as is customary for a "MTU".

Therefore, it would seem that 1500 is not such a wise default value. For 
a typical fast Ethernet (or Wi-Fi) attachment, the MTU would actually 
be 1472 resp 1452 for IP version 4 resp 6. For more intricate scenarii, 
it could be slightly lower (e.g. PPPoE eats an extra 8 bytes).

Am I being confused? is there any rationale for the current value?
