[mythtv-users] Playback drops with news crawl

[Barry Martin]

This problem is more of a ‘rare nuisance’ but it appears some of the 
‘news crawls’ (*) create a problem with MythTV recordings. v34 for 
certain; probably v31 also – LIS the problem occurs rarely.


(*) News Crawl: In the U.S. televisions stations will either add to 
(thus squishing the main display) or overlay (post over the main 
display) announcements such as Emergency Alert tests and weather-related 
announcements (school closings, etc.).


Last night watching Jeopardy! – crawl at the bottom because of the 
snowstorm. No pixelations noted; all of a sudden the display exits to 
the programme select menu (Media Library > Watch Recordings > list of 
recordings to watch). Re-select to play, starts playing at the last 
bookmark, FF to just before where was, plays, exits again – AFAICT same 
spot.


Found if “did a running jump” I could continue past the drop spot – IOW 
Fast Forward – we could continue watching. There were later spots where 
it just exited, but AFAICT not related to anything in the text of the 
crawl nor timing – first exit occurred about 13 minutes in and then 
maybe 5 minutes later, then 3….


Wheel of Fortune aired two hours later, same crawl – might even been 
exactly the same one as there was an error in it – and no issues.



Jeopardy! and Wheel are on an NBC affiliate; also had similar exits on 
CBS and FOX, though locally the FOX station is somehow running through 
(partnered with) the CBS affiliate. I don’t recall any on ABC.



For testing I did:


Tried on two different Frontends: one is a desktop computer running 
Ubuntu 22.04, the other is a Raspberry Pi 4 – both v34.


The original file on the Backend is 2.1GB. I tried to copy so I could 
offer to send to someone to check for the problem but the copies are 
only 786.1 MB – which is that first exit point at 13:44 in. Copying 
methods included mget, then tried to copy to a Thumbdrive to Sneakernet 
to this computer: cp, copy to, drag-and-drop (I know probably all the 
same). All stopped at 786.1 MB. Drag-and-drop did give me a progress bar 
of “786.1MB/2.1GB” and just then sits there, finally erroring with 
“error splicing file”. (So the 786.1 MB point is the same as the first 
exit I experienced,)



If anyone wants a copy of the file for testing I’ll e-mail – or probably 
post to my account at Box as it’s ¾ GB.


Thanks! Barry
