Haxevideo Overflow with latest flash player

[Daniel Frith]

Hi,
I am getting this error if the latest version of flash player
plays/records using haxevideo 1.1:

[2009-03-02 00:28:21] Overflow

Called from haxe/io/Input.hx line 219
Called from format/Rtmp.hx line 126
Called from hxvid/Client.hx line 638
Called from hxvid/Server.hx line 36
Called from hxvid/RealtimeServer.hx line 283
Called from hxvid/RealtimeServer.hx line 142


Any ideas?

Hello,

Rtmp.hx :

public function readHandshake() {
var uptimeLow = i.readUInt16();
var uptimeHigh = i.readUInt16();
var ping = i.readUInt30(); <-------
line 126 causing an overflow error
return i.read(HANDSHAKE_SIZE - 8);
}


You get an overflow error due the fact neko uses 31 bits for integers.
The value read must be higher.

And moreover the way flash communicates with the server regarding
handshake has been changed.

There was some compatibility in the previous versions of flash player
but maybe the last one breaks it.

As "uptimeLow", "uptimeHigh" and "ping" are not used, you can actually
replace the first 3 lines of this function with:

i.readInt32();
i.readInt32();

Regards,

That seems to have fixed it,
Thanks

Fixed on SVN.
