MP1 EVR Presenter/dshowhelper community development (3 Viewers)

[Mitchan81]

Hi Folks,

This thread is for discussions related to community development of the MP 1.1.x/1.2.x dshowhelper, particularly the 'EVRCustomPresenter' code.

The most recent versions of my modified MP1 dshowhelper.dll (and source code) are attached below - they work OK on my system (Vista32, nVidia GT430 with 270.90 drivers, with/without ReClock) but have to be regarded as EXPERIMENTAL so tread carefully !

These dll's are compatible with MP 1.1.0 -> 1.2.1 - compatibility with other MP 1.2.x versions is unknown/untested.

ReClock is not required, but if you use it please disable vsync correction in ReClock - the dshowhelper does it's own vsync correction internally.

The various versions are not necessarily better/worse than each other (or the standard dll), they use different logic etc to achieve vsync correction.

MP 1.2.1 uses a version of v0055f dshowhelper (without MP Audio Renderer support)

Tony

I need some clarification. I installed MP 1.2.1. This standard installation already includes the dll modified to the optimized EVR - VSYNCH? Or should I still download and install one of dll linked in the first message? (in this case...WHICH dll should i use?)

Can I use Reclock with vsynch disabled? Today i use Reclock because MP Audio Render does not allow audio bitstreaming

In short, what is the real advantage of MP Audio Render compared to Reclock in Mediaportal?

THX for all, I love MediaPortal

Yes, you can use ReClock with vsynch disabled.

If the standard MP 1.2.1 dll is working OK for you then stay with it.

last night, following the red5goahead's suggetions, I actually encountered a problem (by viewing the chart with shit + 1) with reclock and audio bitstream: when drops or repeats parts to align the timing of audio with the video i see a micro-stutter. No drop frame video, but a clear stutter. Then I set the audio decoding in software mode with the HTPC (MPA Decoder) and send 5.1 PCM via HDMI to the receiver

Result: No stutter, smooth video and smooth audio

At this point I wonder if I should switch to MP Audio Render,can I have a few performance improvements? Maybe your EVR and your MP Audio Render speak better than Reclock? ... I do not know

In case i want to use MP Audio Render I read that the base dll 1.2.1 does not support it ... so what should I install? My PC configuration is: MB Asus P5Q-EM - Intel G45 (X4500HD integrated graphics), Win 7 x64, Panasonic G20 tv

Thank you and congratulations for your work

Using bitstreaming with ReClock is not recommended.

For MP Audio Renderer use these files - https://forum.team-mediaportal.com/attachments/general-development-no-feature-request-here-48/85158d1310686486-mediaportal-audio-renderer-better-video-playback-quality-accurate_sync_ver_21a.zip

I thought I had solved the problem of smooth video, but I was wrong

using MPC-HC (VSynch on) and Reclock (VSynch off) I get a perfect smooth video

using MP with EVR - dll 55f and Reclock (VSynch off) I get a smooth video with frequently stuttering problems

using MP with MP Audio Render I get a video with frequently stuttering problems

i use CoreAVC in DXVA mode

My PC configuration is: MB Asus P5Q-EM - Intel G45 (X4500HD integrated graphics), Win 7 x64, Panasonic G20 tv

Thank you for your support

Need more info please - a set of logs and a screen capture of the render stats screen would be good......

My guess is that the X4500HD graphics are not powerful enough to cope with MP plus HW deinterlacing plus 1920 x 1080 display.

i will give you as soon as possible (week end)

p.s.= my videos are progressive, not interlaced

thx
