I am currently testing the Mythtv addon. I am running a Mythtv 0.25 backend, clean install Mint 14 frontend (Ubuntu 12.10), and installed Frodo nightly and the addon using the instructions here:

HD Live TV works fine. I am having a problem with SD (analog) streams. Although I don't seem to be having the famous ReadLiveStream: Read 0 Bytes! problem anymore, I do still seem to have some kind of buffering issue. It will tune to the channel every time, but every few seconds the stream will get choppy (video mostly, audio is ok). I'm really not seeing much in the /temp/xbmc.log however.

Is anyone else having this problem, or did I miss a post somewhere on how to fix it?

Thanks.

Hi, please could you tell me which is the last commit of your clone of the git repo. Type:

git log | head -1

I cannot reproduce the lock with my master ! Also is it on raspi or others ? Is the lock is for long time or only few second ?
Thanks.

I looked into the reported lock-ups a bit today and could reliably reproduce them whenever the backend switches recording files when one program ends and a new one starts, based on EPG data. I'm seeing this logged when the switchover happens:

Then the "event file size update" - "no more file" - "wait until livetv_watch is up" sequence repeats. Hope this helps and can be fixed.

I was trying to debug why my recordings list seems to pause about every 10 seconds fro 10-15 secs, so I added some extra logging to pvrclient-mythtv.cpp but nothing was showing up in the xbmc log, so I checked the log for a commonly logged string and found "Event file size update".

So I grepped my files and found the line in "pvr.mythtv.cmyth/src/cppmyth/MythEventHandler.cpp"

I changed line 153 in MythEventHandler.cpp from
XBMC->Log(LOG_NOTICE,"%s - Event file size update: %i", __FUNCTION__, databuf);
to
XBMC->Log(LOG_NOTICE,"%s - Event file siz update: %i", __FUNCTION__, databuf);

I removed the 'e' from size, but after recompiling and reinstalling, the xbmc log still shows it as 'Event file size update'.

I am having this exact same issue, with choppy SD video and HD is fine, using mythtv back end. Using MythTV .25 and I have a PVR-500 for SD. Did you happen to figure this out?

I did not figure this out yet. I assume it's a buffering issue, but am not sure.

Perhaps because I didn't attach a log file on my original post. I am still using a quite old version of the Add-On on my main TV that is working well enough for me...

Can anyone give us any insight into this? Is this a known problem? Would you like me to attach some log files?

This issue is specific to playback via the PVR interface.
I am using the cMyth plugin. Backend is MythTV 0.26 Debian over GigE.

When playing back a HD recording, playback pauses/rebuffers randomly.
Frequency of occurence is once about every 1-2 minutes.
Playback is through the PVR interface using the cMyth plugin.
All my feeds are captured using a HD Homerun on FIOS TV.

I can play the same files through the XBMC "Videos" interface with no issues.
(I have my MythTV captures cross-mounted via NFS)

I have reproduced this issue on OpenELEC and RaspBMC.

I cannot duplicate this issue using VLC on windows, over SMB share.
I cannot duplicate this issue using XBMC Frodo RC2 on Windows.
I cannot duplicate this issue using Myth frontend on my Linux laptop.

This only occurs on high bitrate (~18Mb/s) HD recordings.
I cannot reproduce on lower bitrate (~2.5Mb/s) SD recordings.

NOTE this issue is unrelated to the other playback issue documented in several
other threads, where a hard pause occurs at commercial breaks in recordings.

As far as I can tell, this is NOT a recent regression.
I still see this problem as of latest OpenELEC nightly (r12735)
which includes the latest cMyth plugin (v.1.6.6)

Sorry if this already being worked on, but I have spent a lot of time trying to
figure out this issue, and wanted to make sure this was written down.

Happy holidays to all the developers and contributors!
