not bug,when the gmediarender playing on my mips ,the CPU occupancy rate upto 90%

My mips CPU frequency is 400MHz.Sometimes,the playing music not smooth.Have some idea to reduce the CPU occupancy rate?

Decoding music is CPU intensive. Often these older CPUs don't have a floating point unit, which makes it extra hard: a lot of decoders use floating point operations.

• Make sure to use Alsa directly and no pulseaudio, as this tries to do re-coding and stuff, which is expensive.
• Use Audio formats that are cheap to decode, such as flac
• For other audio formats: make sure to compile all necessary libraries with whatever floating point flags your compiler supports.

My CPU not has hardware floating point unit,and I use Alsa directly. When I using gst-launch playing music ,it about 40% CPU occupancy. I dont understand why the cpu occupancy is so high when using gmediarender play. I thank may the libupnp or libxml has not optimized

Interesting, I need to look into this. gmrenderer itself only has one thread that checks every 1/2 second the current position of the stream, but I don't know what else is going on in the libraries. I'll have a look (but not before the next weekend).

I found it is my driver's problem,thankyou!

Glad that it got resolved.
