Subject: [Helix-server-dev] Helix Server Stream .3gp file over rtsp
Message-ID: <200905210947.39704.manuel.arguelles@gmail.com>

Hello, I need to stream a .3gp video file over rtsp, I downloaded the helix dna 
server, but I haven't found the way to make it work.

Also I can't any user guide about helix dna server use.

Could you please show me the way?

Subject: [Helix-server-dev] ASMRuleNumber and live archive
Message-ID: <505897.35994.qm@web706.biz.mail.mud.yahoo.com>

Hello,

We are working on helix server live sink plugin. One question comes up is when we get packet from PacketReady callback, each packet has ASMFlags and ASMRuleNumber associated with. Based on our tracking, it seems that ASMRuleNumber = 2 means it is part of keyframe, and but not sure what are the definitions for other values, ASMRuleNumber = 0 and 1.

While archiving the stream,  we found by experimenting that we can only take all the packets with ASMRuleNumber equal to 2 or 1 (after starting from packet with ASMRuleNumber=2 first, so skipping all 0 or 1 packets), then we need to skip all packets with ASMRuleNumber=0, otherwise, the archived file will be polluted with incorrectly decoded blocks, but we don't know why this is way it seems to be?  Also are there any particular usage with ASMFlags's value? thanks much,

alan
