From 9e125d30a241de93889d470b1aca684c39ab9e26 Mon Sep 17 00:00:00 2001 From: Antonio Ospite Date: Thu, 7 Apr 2011 12:21:38 +0200 Subject: [PATCH] Add a configurable stream_flag field For now only video stream is supported which has stream_flag = 0x80, but having the value hardcoded in the sd_pkt_scan routine didn't look pretty. This way there is more flexibility in preparation for adding depth stream support.
