MP1 EVR Presenter/dshowhelper community development (1 Viewer)

[Holzi]

Hello!
First I wanna thank you for your amazing work! I just did some tests two weeks ago because I got bored and I saw a lot of people say v92 works great and they use it. But for me the original files coming with MP 1.2.2 (I just replaced the TSReader.ax with the fix from here) do perfect and I use them now.
Hopefully disaster123 can provide you useful logs as I don't have access to my HTPC this week.

Same with V0092a_no_dwm. I can't provide a screenshot as is still don't know how to make a screenshot with remote and IRSS.

Here are the Loglines:

i could "fix" the 2 minute stuttering by using the latest available git Accurate_Sync branch and applying the following patch (it just groups the important settings) and enables MCSS for the threads (except DWM) and sets all priorities to HIGH for them.

If that works on your system it's fine, but be careful with MMCSS - it's a pretty 'aggressive' scheduler so it's easy to mess up the performance of other threads if you go too high with the priorities (been there, got the tee-shirt )

Hi disaster123,
could you please post your new dll. thanks in advance.

Hi disaster123,
could you please post your new dll. thanks in advance.

Remember to add some logging information so Tony doesn't have to wonder about possible odd reports people are writing (behavior not matching the actual code )

For sure. Added Disaster123 v0.01 dshowhelper as an additional log line.

Hi Guys, I don't like jumping to conclusion but, dshowhelper_092 with DWM (what's this DWM ???) has improved my viewing experience in LiveTV using the Hauppauge Colossus and my HD STB. I was pleased with the orignal one of MP1.2.2 (055f) all lines was flat with some drop here and there. But the 092w/DWM gives me almost no drops. My 3 lines graph is kind of "wavey" ~~~~~~~~~~ but the result is great.

I'll stay with dshowhelper_092w/DWM and report my experience back.

again, keep up the great work.

DWM = Desktop Window Manager = 'Aero' desktop. (Aero isn't just eye candy - it changes the way rendering to the screen works).

The 'DWM' versions of dshowhelper enable 'queued mode' rendering in the DWM, which seems to improve performance with some video cards/drivers. The standard and 'no_DWM' versions don't have this enabled.
