Rather than "fixes", maybe should have written... circumvents the transport stream thumbnail issue.

Strongly disagree with this one, it is never a good idea to cover up one f***up with another, just ask Sean Spicer ;) .

It will blow up in someones face (the more stupid OSes out there, like the one from that obscure company in Redmond, who only look at the extension probably wont like that) one way or the other...

IMHO it makes a lot more sense to document this bug in ubuntu (which btw i don't see in LinuxMint, i'm not getting thumbnails on eighter ts nor m2ts) in the wiki.

my two cents...

/hp

But ".ts" files are not always mpeg-2. :) ".ts" means "Transport Stream" and covers ALL content.
The ".ts" extension is well know and most commonly used everywhere, to change it would cause lots of problems for people relying on the (correct) extension of ".ts" for transport stream recordings.

This is an OS (Ubuntu) issue and should be solved there...

Thanks for your replies,

Will abandon this idea then. First considered (and was using) .mts, but noticed .m2ts mentioned/used more frequently, Wikipedia mentions MPEG transport stream (ts) extended to .m2ts. My bad, assumed they were different extensions for the same encoding!
Back to using ~/.local mime-type then. :)

While testing, noticed Kubuntu 17.04 doesn't seem to have a .ts thumbnail issue, maybe there's been an upstream fix, or since mime-types seem the same, a thumbnail generation modification/improvement? Will test other Ubuntu based 17.04 editions in few days and report back.

Must apologise, mentioned I'd report back and didn't. Tested few other Ubuntu based distributions with VirtualBox, they handled my .ts test files in the same way. Few hours ago, tested Kubuntu 17.10 as a live session (bare metal) most of my .ts test files were incorrectly identified as a text file, but one was correctly identified as a video and its thumbnail was generated.

Experimented with using a ~/.local mime-type, but (even though may be seen as an incorrect approach) decided to return to previous method of changing Tvheadend's pass string, so all recordings have a .mts suffix, and all files automatically generate thumbnails without further user intervention.
