MediaPortal Audio renderer - better video playback quality (2 Viewers)

[edterbak]

@ Red5 and seeco,

Thank you both for the clarification. I rarely have time to tinker with or look at the system now. From the top of my head, I thought the judders were visible in the red lines (shift 1) as well, but Im not 100% sure. Can I conclude IF the judders are present in the source, I woulndt see a jump in the red line? If so, I will look for this with more attention.
If I see the judder and the redline is stable, I guess the source is the problem. (am I right?)

Hello,
I use SAF 5 unlock, with MePo Audio Renderer and ffdshow as Audio Codec (no passthrough of course).
I have 2 questions about the synergy between MePo audio renderer and:
1. The "Dynamic refresh rate" of the MePo configuration, I use it to automatically adjust my screen refresh to the video. Is it ok to use it with MePo renderer?
2. The video codec to use. Currently I use ffdshow video for SD video and PDVD10 for HD video and TV SD+HD. Can we use the video codec we want with MePo renderer? Or is there one that is preferred?
Thanks in advance.

The best way to be sure it's open the source with player such as MPC-HC and check the footage frame by frame .
Anyway most Abc releases have that issue. Another good solution to test with better reliability it's using a web-DL mkv release.

@ red5: Thanks for the confirmation! I have already made a habit of avoiding those encodes, favouring web-dl releases instead. My girlfriend seems to be immune to stuttering, she never sees it while I become furious over every little hick-up

Using the dynamic refresh rate functionality in conjuction with the audio renderer will give you the best possible quality of output, providing your TV supports the required refrsh rates.

2. The video codec to use. Currently I use ffdshow video for SD video and PDVD10 for HD video and TV SD+HD. Can we use the video codec we want with MePo renderer? Or is there one that is preferred?

There is no restriction on Video Codec, although it may be better not to use the renderer for TV if your TV refresh rate is faster than the rate from your TV provider i.e. if your TV refresh rate is just over 50Hz and the TV is PAL then the renderer will try to show the TV programme faster than it is available.

Thanks davidf,
It's clear to me now
I will do some tests with the TV with and without MePo Audio Renderer.

Hans, if i look very quickly i see on the screenshots that your display refreshrate is set to 24hz, if i'm correct nothing is speedup then. I don't see why you need this speedup if your display can do 24hz.
Please make sure that the audio output settings are correct for ffdshow and screen refreshrate set to 25hz/50hz. Precise audio settings somewhere in this thread.

The display can handle 24 Hz but the movie is 23,97 fps. If I set the screen to 25 Hz it is indeed more obvious that the renderer does not speed up the movie.
Do you mean that although the renderer is in the graph it still might not work because of the audio settings?

Hans, with 24Hz it will not speed up. With 25/50hz it should speed up. If it does not speed up make sure you did not selected pass through in audio settings of ffdshow and make sure you installed and registered the binaries correctly.

hans.kazan,

It should speed up 23.97 material on both 24Hz and 25Hz displays, could you provide logs when this (doesn't) happen?

cheers

Ok, sorry Davidf, i thought 24hz was not speed up.

Myself i have an issue with the encoding for multichannel audio through SPDIF and HDMI (tried both).
I see mpaudiorenderer is used and working great by the way for video, but i cannot get DD and DTS to work. Only 2 channel audio is seen on the receiver.
Tried multiple versions of SAF 5.00. ac3encode is set to 1 in registry. It still does not work.

Complete logs from DTS and DD source attached.

=====================
Fixed it myself
Had to disable the mixer in de ffdshow audio settings. Decoding to stereo was the setting
For the people with stuttering DTS audio, under ffdshow codecs DTS set it to libdts.

Everything is working fine now. Thanks Tourettes!
