Liquidsoap uses more CPU when streaming silence than when streaming audio?

Romain Beauxis added a comment - 20/Oct/11 5:17 PM Very likely to be related to: "Encoding blank (hide) Encoding pure silence is often too effective for streaming: data is so compressed that there is nothing to send to listeners, whose clients eventually disconnect. Therefore, it is a good idea to use a non-silent jingle instead of blank() to fill in the blank. You can also achieve various effects using synthesis sources such as noise(), sine(), etc." http://savonet.sourceforge.net/doc-1.0.0/faq.html

Dmitry added a comment - 26/Dec/11 3:10 PM I can confirm this behavior with latest Liquidsoap version for Windows. Silence streaming _sometimes_ uses CPU up to 8 times higher causing CPU usage for 100 when several liquidsoap instances are running. If I restart all instances and play silence immediately after restart, it work as usual, but after some time CPU usage is increasing dramatically. I will try to analyze in details and find out when exactly it happens.

Daniel James added a comment - 23/May/12 3:18 PM In Airtime 2.1.0 the CPU usage is much lower when streaming a silent Ogg Vorbis stream than it was in 2.0.3 or earlier, but using the same version of Liquidsoap (1.0.0). So this may have been a different issue to the one reported above for Windows.
