Hi all.<br>
<br>
To start with, I have found a work around to my
issue, but I still don't understand what is going
on. While typing this email and listing out what all
I tried, I discovered that changing the playback
profile from vdpau to opengl seems to correct the
issue. CPU runs higher, and I am concerned that may
cause problems with some recordings, but it is
working for now. I just don;t understand why vdpau
isn't working like I think it should. The below is
all with the vdpau playback profile (slim, normal,
high all do the same)<br>
<br>
Graphics Card: GT1030 using HDMI out and audio over
hdmi<br>
<br>
I am having issues with playback of 720p video. When
watching it is most obvious with the sound. Using a
video camera, I recorded the playback to share. I
also have the playback data displayed on the screen.
It is a small file (22.2MB) that may be downloaded
using the link below.<br>

<br>
I started mythfrontend from the terminal with
--loglevel debug: No errors showing up.<br>
<br>
Both frontend and backend are connected to wired LAN
at 1000Mbps<br>
<br>
It did not used to do this. I briefly thought it was
my graphics adapter because my cooling fan was going
out, so I went ahead and upgraded to an nvidia
GT1030. No change.<br>
I've tried different versions of the nvidia driver.
No change.<br>
<br>
I have audio upconversion turned off. Realtime
priority threads is off.<br>
<br>
I also ran across an email in this forum where
advice was given to do some check on vdpau setup. I
ran several of those checks and saved the text to a
file that can be downloaded from the following link:

Sorry for such a long message. Any help would be
appreciated.<br>
<br>
Thanks,<br>

Please start the frontend with -v playback and view the
recording under vdpau. The log will show more information
about what is happening here. Please post the log
somewhere (e.g. pastebin) and let me know where it is.<br>

<div>Thanks the extra info from -v playback looks helpful.</div>

<div>Based on that log file, it looks to me like the audio
is actually the root of the problem, not vdpau, but I
still don;t know what to do about it.</div>

<div>Thanks for the help.</div>

If you are running master:<br>
On frontend navigate to Setup->Video->Playback->General
Playback<br>
Increase the value in Audio read ahead (ms). The default is 100 but
you can go up to 5000. Hopefully this will resolve the problem.<br>
<br>
On previous versions this was called <span class="pl-s">Extra audio
buffering. Make sure that is checked if you are on a previous
version.<br>
<br>
If you have a previous version and Extra audio buffering is
checked already, try in playback to change audio sync. If
changing audio sync in a positive direction gets rid of the
stuttering but messes up lip sync, then using the audio read ahead
would fix it if you were using master.<br>
