MP1 Upgrade to 1.17 causes playback of recordings to stop (1 Viewer)

I uploaded 2 short US ATSC programs 2 or 3 years ago. Both SHOULD have ATSC-CC but I have not looked. The following google drive link should have shared access enabled

From the two sets of logs I've looked at, it looks like the Core CC Parser + video decoder filter path is hanging (refusing to accept samples) after a seek sometimes - the TsReader log shows a lot of buffered video samples (> 600) when it hangs because they can't go anywhere.

I'll try and reproduce the problem...

I've managed to reproduce the hang a couple of times (with one of my old ATSC CC test files) so I'll create a JIra entry for it and do some debugging...

Great

Interestingly I couldn't get it to hang with the two test files RonD supplied, so the problem seems to be file/stream dependant (to some extent).

It's not a deadlock ? then ?

*I think* I've worked out what is happening and hopefully fixed it.

@OTA Watcher - Please try this new v1.0.0.1 version of the Core-CC-Parser filter (cccp.ax).

To install it, copy the cccp.ax from the attached zip file into C:\Program Files (x86)\Team MediaPortal\MediaPortal (after making a backup copy of the original).

Please let us know if it fixes the problem.

(The Git branch with the changes is here - GitHub - MediaPortal/MediaPortal-1 at MP1-4892-BUG-TV_CC_hang_after_seek )

I'll give this a try on my US ATSC systems, I also see some problems with ATSC CC and time skipping.

@Owlsroost On a different topic since core-cc source is available. On some USA NBC shows, most of the closed captions are displayed but many are missing. I'd guess its 70% work 30% missing. For 1 or 2 shows I've watched the same recording with vlc.exe and all the closed captions show up. If this is something that can be fixed, I'll start a new thread. I'd need to find consistent failing video

It may be possible to fix it, but as you say you need to find a suitable test recording so we can investigate the problem. The base CC parsing code in the Core CC Parser filter is quite old (the original CCCP source files were copyright 2004).

Bump - any feedback on the new Core CC Parser filter?
