CPU usage too high!

[daWsOn_s]

Hello,
first of all thanks for your work here Rel, I'm glad you added recording in TS with all audio pids I like to know if there is some option to disable mpeg2 decoding like ProgDVB does. I mean, when I schedule recording with the option "disable video render" (renderless) the CPU usage is still 30-35% (watching video is about 40%) insted of ProgDVB that when I disable mpeg-2 decoder it records whit 8-10% of CPU.

Thanks.

Already reported in beta testers forum - I see - by you.

Yes, Rel said I had to post bugs in public forum

[daWsOn_s]

so...is it normal?

does it happen only when you start renderless recording from scheduler ? or everytime also with record button or shorcut?

Everytime. Now in 1.3a 35-40% if renderless mode disabled, almost the same if enabled (FTA channel).

When just watchig FTA channel, it's 10-20%, renderless mode enabled (still no recording) 0%, so renderless mode is not broken completely.

I tried also with disabled timeshift, results: 25-35%, with renderless mode enabled 20-30%.

Yes, I confirm

[daWsOn_s]

So what happens now?? It's impossibile that a dvb software uses 90-95% of CPU recording in mpeg2 during watching!

But this bug has been already fixed.

Watch values in Windows Task Manager, not in DD's status bar - there is a global CPU usage! It might be some other program, you can check it in Processes tab in Task Manager.

v1.3c - FTA channel - recording - 5-15%! Recording+Renderless mode 0-2%!

[dwarves]

in my case server4pc usage about 45% cpu!!! so.. i disable it... and everything fine..!


GREAT WORK with DVBDREAM...!

[daWsOn_s]

Yes I confirm, i didn't update the software when I wrote. But...why the watching CPU usage is so high? I mean with progdvb or altdvb with FTA-mpeg2 channels the cpu remain in 25-29% while in dvbdream stays always over 60%!!

I can't find your PC config, right now (in v1.3c) CPU usage at FTA channel is 2-6%! With ATI codec and overlay renderer, I tried also InterVideo, CPU usage has increased to about 15%, so try other codecs, renderers...

[daWsOn_s]

Yes, you were right, it was a render problem, now with the mixing render cpu at mpeg2 fta channel is 26-29%

[Dreamer]

OK, so can I close this topic?

[daWsOn_s]

Yes you can! Just for the records, renderless mode takes only 5-8% of CPU! GREAT!
