[vlc-devel] [VLC] #6191: high cpu usage on ts mux output since ver 1.0.0

[James Mrozovich]

Thank you for your super fast response!!! :-)

as per your direction I have used file output instead of a network stream,
both 0.9.9 and newest daily worked and created a playable ts file. both
versions did crank the cpu up during the processing.. both took roughly the
same time. I want to add that when outputting to a file VLC will go as fast
as the system can handle and streams to file 1 minute of 1080i content in
11 seconds, while my network multicast will stream the ts in real time, eg.
1 minute of ts yields 1 minute of streaming. so its hard to say that the
processor spike while outputting to file was due to a VLC bug or simply
using all available resources to dump the output file as fast as possible.
included below  are the output strings used for the test.

VLC 0.9.9 Win32
:sout=#duplicate{dst=std{access=file,mux=ts,dst=C:\Users\owner\Desktop\099.ts}}
11 seconds

VLC Newest 2/22/2012 Win32
:sout=#file{dst=C:\\Users\\owner\\Desktop\\new.ts} :no-sout-rtp-sap
:no-sout-standard-sap :ttl=1 :sout-keep
11 second
