Hugh cpu difference between MSVC and MINGW version 1.18.2

[marc lievens-2]

 

On windows 10 prof with cpu Intel i7- 6 core, I see a huge cpu difference between the msvc and the mingw libraries.

For 64 cameras I see that :

- msvc uses 30% cpu

- mingw uses 20% cpu

 

Used pipeline is Rtspsrc ! rtph264depay! h264parse ! qtmux ! filesink

 

Any idea about this cpu difference and can this be solved in the future?

I prefer to use the msvc version, but this is now not possible due to the cpu load.

 

Cheers

marc

That is rather surprising, especially since none of these element
really *do* much.

Where do your GStreamer binaries come from, did you build them yourself
or do you use our packages?

Hi Tim,

The used Gstreamer binaries are comming from the official gstreamer web side.

We do not build or make changes to Gstreamer..

Cheers ,

Hi Tim,

 

The problem about cpu difference is also the case with the original libraries from Gstreamer 1.18.3.

 

For 64 cameras I see that:

- msvc uses 30% cpu

 - mingw uses 20% cpu

 

Used pipeline is Rtspsrc ! rtph264depay! h264parse ! qtmux ! filesink 

We also use rebust muxing

 

Cheers ,

 

marc
