720p MPEG Issue - ABC HD (Live TV PVR) #6

Closed darrenkdean closed 9 years ago

darrenkdean commented 10 years ago

When watching Live TV (PVR), ABC HD (SEC Football) has significant buffering issues ultimately leading to the G-Box freezing. Audio & Video appear to continually fall out of sync leading to images stuttering and fast forwarding to try & re-sync, before finally crashing. ABC HD appears to be broadcasting as a 720p MPEG which is different than the majority of channels & has been an issue across many Android & Linux builds. Thank you in advance for trouble shooting this issue.

Which front end are you using?

Simple IPTV , TVHEADEND HTS , Vnsi or XVDR?

it is very important to know because first 2 of them are having issues from the producers of the addons.

For me VNSI and VDR performing quite fine with vdr backend even in high bitrate 1080i channels

Good Morning,

We are currently using Windows Media Center Client - linux arm Edition for the front end with Server WMC running on a Windows 8 WMC Hyper V Host. Had previously been using NextPVR for both back end & front end & had experienced the same issue.

Upgraded to the latest test build 4.2 Beta 6 yesterday & do not seem to be experiencing these issues. 1080 has not had any problems in the past, only 720 broadcasts. The issue came up again for the first time in awhile last weekend on a SEC Football broadcast on ABC HD. Will wait for another game to broadcast on ABC HD & report back to determine if it is certain types of 720 broadcasts. Would it be helpful to record & send part of the stream if I can isolate where it's coming from?

Best-

Darren

720 Dolby Digital 5.1

I'm using Simple IPTV PVR addon. You can try to play with the following settings in your advancedsettings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<advancedsettings>
  <pvr>
    <minvideocachelevel>20</minvideocachelevel>
    <minaudiocachelevel>20</minaudiocachelevel>
  </pvr>
</advancedsettings>

Updated to the latest test build & added the settings above to advancedsettings.xml. Have not been able to recreate the sync issues since making these changes. I would consider this issue resolved. Thank you for your assistance.
