I was wondering about the onStatus messages that are sent by mod_rtmp to Flash Player. The RTMP Spec (see page 38 of http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/rtmp/pdf/rtmp_specification_1.0.pdf) says that the transaction ID for onStatus messages is supposed to be 0, but mod_rtmp uses 1. It seems to work fine, but I wanted to check if anyone knew if it might lead to problems not by following the spec.
This is in rtmp_sig.c, for example in rtmp_i_play.
