Mythweb: Streaming from slave backends

Reported by: Stefan Enzinger <mindoms@…> Owned by: Stuart Auchterlonie

Description

I did write up some patch for mythweb to enable streaming of recordings from slave backends.

My system is mythtv .27 on ubuntu 14.04.3

caveats:

  • requires libwww-perl (was installed on my clean ubuntu/mythtv setup)
  • high cpu usage on mythweb host (I'm trying to contact LWP maintainers)

please let me know what you think or if this is the wrong place.

the diff is against git: e56118573fad47a0272631156b2a390128a5c8ba

but I did only test it on my current ubuntu setup with mythweb: 2:0.27.0+fixes.20140324.8ee257c-0ubuntu3

Lowered cpu usage and increased throughput by increasing a buffer size. Size defaulted to 4k. Small changes didn't make a difference so I increased it to 4M.

I had to copy and modify the code for getprint from ​https://github.com/libwww-perl/libwww-perl/blob/c1006d428cef2290d1b41e4a9cb7b2981262caf6/lib/LWP/Simple.pm#L61
