Apache DVB http video Streaming bandwidth or priority problem
- by igino manfre'
I'm streaming few precompressed DVB videos from cloud. The streams are generated from VLC on "impossible" ports (such as 64085, 64086 etc) reverse proxed by Apache on port 80 and 8080.
All the generated streams are listed in "http://95.110.164.61/indexv.html".
From an ADSL connection with enough downlink bandwidth, recalling the stream generated by VLC (such as "http://95.110.164.61:64087/mpg2_6.4") it flows fluently.
Recalling the same stream proxed by Apache ("http://95.110.164.61/mpg2_6.4") the stream stops and goes.
The only situation in which the Apache proxed streams flow regularly is from a site connected through 64 Mbps warranted bandwith with RTT to the server less than 10 mseconds.
Please note that streams below 2 Mbps are fluently proxed.
The system is a single core xeon with windows 2008 R2 on 4 GB of RAM with 1 Gbps of network bandwidth. The drain of computational and bandwidth resources is negligeable, the RAM usage always lower than 50%.
On the system I run many VLC streamers. Any of them drains a variable amount of RAM (from about 25 to 70 MB). On the contrary the couple of httpd.exe processes drain no more than 7 MB.
Using Wireshark (on the server) I see that VLC directy send to the client much more packets than Apache, and the stream is framgmented on many frames.
I'm not a programmer, a newby of Apache.
Can anyone please address me to a specific portion of the Apache's huge documentation?
Thank you.
