[Live-devel] current position, time problem

[Ross Finlayson]

> We have "Amino A139 STB" , and live555 server running on "Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-32-generic x86_64)”.

Linux ‘distributions’ (such as ‘Ubuntu’) usually contain old, out-of-date versions of the LIVE555 Streaming Media software.  Please make sure that you are running an up-to-date version of the software.

I suggest using the pre-built Linux binary “live555MediaServer” application, available from
	http://www.live555.com/mediaServer/ <http://www.live555.com/mediaServer/>

Note also that to perform ‘trick play’ operations when streaming a MPEG Transport Stream file, you will need a corresponding ‘index file’.  This is described here:

Amino apparently uses a RTSP “GET_PARAMETER” command - with a parameter name of “position” - to request that a server return the ‘Normal Play Time’ (i.e., current position in the stream).  This is completely non-standard, and I will not consider adding *any* such support to the “LIVE555 Streaming Media” software unless I am contacted *directly* by ‘Amino Corporation’ (not just by some intermediary).

I recommend that you instead use some other - more standards-compliant - set-top box client, other than ‘Amino’.
