    AW: MediaPortal Audio renderer - better video playback quality

    Hi,

    I have a problem playing a DVD.
    The DVD has only one Track: 2.0 LPCM

    In MP I get only cracked sound and ffdshow thinks it is 5.1 PCM as input. :confused:
    I think thats the problem.
    Graphsudio seems to be fine. Only ffdshow Audio -> MP Audio renderer.

    With Graphsudio, MPC and so on, no problems. All is correct, ffdshow detects 2.0 input and the sound is fine.

    Code:

    Hi,

    I have a problem playing a DVD.
    The DVD has only one Track: 2.0 LPCM

    In MP I get only cracked sound and ffdshow thinks it is 5.1 PCM as input. :confused:
    I think thats the problem.
    Graphsudio seems to be fine. Only ffdshow Audio -> MP Audio renderer.

    With Graphsudio, MPC and so on, no problems. All is correct, ffdshow detects 2.0 input and the sound is fine.
    Click to expand...

    Audio renderer shouldn't be able to affect ffshow any way when it comes to the audio stream format. But if it works with other audio renderers then I need a sample of that DVD.

    just as a side note..i DO in fact have the dts/etc passthru options ON in ffdshow and the guide says not to...wondering if theres a reason for this?
    Click to expand...

    When passthru formats are enabled the audio renderer will refuse those formats as input.

    But everso often with using this audio render, the audio does not work/recover after a channel change. The audio beomes quiet, with a click type noise every few seconds from that point onwards. Video still lays fine.
    Click to expand...

    Can anyone else reproduce this issue? I cannot. From log it would look like the audio renderer is receiving the data too late and therefore it will drop the samples. Could be TsReader or audio codec issue as well.

    Ok, here is a "sample".
    I deleted all big VOB Files, so it's only the still menu with the sound.
    If thats plays fine, the wohle disc shoul play too.

    well i cant fault much with this audio renderer atm apart from the passthru restriction
    Click to expand...

    Unfortunately that restriction is there from a theory point of view already (as explained in more detail in the 1st post). Since audio needs to be resampled it is not possible to bitstream it. I can only alter the actual audio data, not the HW that plays it (that would allow playback speed change for the bitstreamed data :)).

    Hi - just installed the MP audio renderer which has solved stutter in my HD and SD freesat viewing - thank you :)

    Is there anyway to use this and still have DTS-HD in mkv's sent to my amp (not hdmi, I use 5.1 analog connections) and is there any way to get auto fps switching working either in MP itself (50hz, 60hz, 24hz) or using another program for mkv playback?

    thanks for solving my stutter though, made me a happy man!

    Hi there,

    I will do some more testing and capture more logs for you. I can appreciate audio/video getting screwed on the channel change, but I would have hoped the audio would "recover" after a very short period of time and play ok.

    It might just be a "quirky" thing with my HTPC :(

    Many thanks,

    J.
