Re: AW: MediaPortal Audio renderer - better video playback quality

Megaupload seems to have some problems these days.
File should now be working again...

Still the same issue, not able to download it. Could someone who has access to that file upload it to:

Address: ftp.team-mediaportal.com

WMA 6CH 48000hz - The Dark Knight 2008.wmv
uploading now

DONE

I can reproduce the issue, seems to be related to the IMediaSeeking implementation that is not complete on audio renderer's side. To me it looks like a codec bug since audio renderer is correctly returning the E_NOTIMPL to show that the interface implementation is not complete. Not sure if there is any other way to workaround that than to provide the full implementation of that seeking interface

Hi tourettes,

I am also a happy user of this great audio renderer.
I have a question and could not find the answer in the thread or the first post. What speeds can this audiorenderer adjust?
Have seen 23.97fps to 25fps to 50hz display. But can it do 29.97 to this 50hz display also? I have a 720p mpeg video (toy story 1 and 2) 29.97fps and i see the renderer does nothing with it. Shift+1 shows 29.97-30.00 fps.

Greetings,

Wouter

You can control the speed up / slow down limits by following two registry settings:

MaxBias

Maximum allowed speed that the playback can reach, this value is divided with 10000 to get the real value. Default value is 11000 (1.1x) - 10% speed up at maximum.

MinBias

Minimum allowed speed for the playback, this value is divided with 10000 to get the real value. Default value is 9000 (0.9x) - 10% speed down at maximum.

Slowing down 29.97 to 25 is quite big step, so it would make the movie itself look quite bad / strange.

Thanks for the reply Tourettes, i'll try that, or else i have to use the refreshrate changer in MP for that to switch to 60hz and do it from that point. My plasma can do both.
I read something about telecine is that not usable for translating 29.97 to 25 ?

Thanks for all the work Tourettes. 99% of all files play perfect now!

I have one one 'issue' remaining. I own a WMV file (Dark Knight) which contains:
Format : WMA3
Format profile : M2
Codec ID : 162
Codec ID/Info : Windows Media Audio 3
Description of the codec : Windows Media Audio 10 Professional - 768 kbps, 48 kHz, 5.1 channel 24 bit 1-pass CBR
Duration : 2h 32mn
Bit rate mode : Constant
Bit rate : 768 Kbps
Channel(s) : 6 channels
Sampling rate : 48.0 KHz
Resolution : 24 bits

When I select Mediaportal Audio Renderer, it always starts from the beginning. FF/RWD is not possible as well.
When I select any other renderer (Xonar in my case) all is fine and it does FF/RWD as well.
Is this an issue cause by the renderer which can be fixed or something else?

Here's a audio renderer binary that should fix the issue (duration should be now reported correctly with audio decoder's who don't understand what not implemented means ))

Please test and report for two things:

1) no new issues are seen (seeking or duration related, others shouldn't be result of the fix)
2) duration is working ok for files that contain WMA3 audio

Log will contain following information to identify the correct binary being in use:

MP Audio Renderer - v0.994 - duration test

If the testing goes well I'll release this binary as version 20 (unless something critical pops up before that).

tourettes,

I will test tonight. Any special cases youd like me to test? DVD/TV/Video rates? Is there perhapes a kind of 'standard' test set available?

Seeking and duration are working now

I will report if there are any "new" problems.

Test as much as possible. But at least few different audio formats and skipping / seeking in those - different video rates doesn't need to be tested.

I had used the test version yesterday evening with many different filetypes/refreshrates.
No problems
