Hi

I have just set up a new system (Pentium G4560 Kaby Lake, internal graphics, Win10), installed the latest MC from JRiver (22.0.105) and set up my tv-tuner sucessfully (Hauppauge WinTV soloHD).
If I start live TV, MC shows an error saying that it was unable to connect the video codec with the splitter/source. I am trying to watch the new DVB-T2 here in Germany which uses a hevc/h.256 codec. I have tried red october hq and standard, with and without hardware acceleration.
If I record programs in ts-format, I can watch them without issues (3% CPU!). If I use the standard jtv-format, I get the same error in playback.
I have tried the tuner with the VLC media player, it works.
Can you help?

@yaobing: I will send you a log file.

Thanks
Kai

Have you been able to play the channel previously, using a previous version of MC, or on a different computer? 

Are you not able to play all channels that use H.265 video?

Have you been able to play the channel previously, using a previous version of MC, or on a different computer? 

No, my old computer was not powerful enough - hence the upgrade.

Are you not able to play all channels that use H.265 video?

Yes, none of the channels is working.
I used the same tuner with the old dvb-t standard (H.264) in MC 20 since they switched to hd and the new encoding a few weeks ago.

[Yaobing]

I will investigate.  We have had users who reported success in watching H.265 channels, but I do not know if they are in the same country as you are.  Can you upload some short recordings (to a file share service - Dropbox, or OneDrive for example) and share with me?  One recording in TS format, and one in JTV should be enough.  Please zip up the entire folder for JTV recording.

[Kai]

I will send you a link to some files via email.
Note: The ts recording is playing fine in mc, the jtv not. Problem is, I cannot use timeshift with ts.
btw: If I start live tv with timeshift disabled, I get no error message - but no picture either, just sound. Weird...

[Yaobing]

Please download from this link, un-zip, and
1. Copy JRTelevision.dll into MC22 installation folder.
2. Copy the two .ax files into <MC22 installation>\TV\ subfolder.

Thank you so far. It looks promising, but I get a lot of crashes.
- Timeshift TV: If I start TV, MC crashes about one out of four times (tested in red october hd and standard, makes no difference). Sometimes this also happens on switching channels. Is there a way I can send you a crash report?
- Watch recordings (jtv): seems to work, no crashes yet
- TV with timeshift disabled: crashes every time. In this case I get a crash report from madVR. I will send it to you via email.

Best,
Kai

edit: forgot to say - if MC does not crash, TV is now working fine!

[Yaobing]

I got the madVR crash report.  It is not much help because we do not build madVR.  To reduce complication, stay with Red October Standard and try reproducing a crash (running live time-shifting for example).  Immediately after the crash, start MC up, go to Help > Logging, and click "Report problem...".  It will create a zipped package of log files and possibly a crash dump file.  Email me the entire package.

[Kai]

Ok, send you the logs.

[Yaobing]

Thanks for the logs.

It appears to be a case of version mismatch.  I built the DLLs based on newer code than build 105 that may not be compatible with 105.

Please try these new DLLs that I built using 105 code base.

Thank you Yaobing! I tested the new files and nearly everything works now. Great!
There is only one small problem: If I turn timeshift off (in the preferences), MC becomes unresponsive and crashes if I switch channels. I will send you another crash report. But this is really a corner case, since I normally keep timeshift on.
Best,
Kai

[Yaobing]

Thanks.  Yeah, keeping time-shifting on is the way to go.  There is no real reason to turn it off.

Does switching channels work in time-shifting mode?  In the particular case in the last log you sent, channel switching involved an audio format change (from EAC3 to AAC).  I wonder if that was what triggered the problem.

[Kai]

Yes, switching in time-shifting works.
