Add Video transcoding match attribute for variable framerate

[JezzaT]

My Bravia doesn't play variable framerate h264 at the right speed (Files like the one below play something like 4X fast) so I want to transcode those files rather then remuxing but I still want the constant frame rate h264 to just remux

To get around not having this attribute I remux constant frame rate 16:9 videos into m2ts and transcocde h264 in all other containers which is not ideal

[Illico]

Could you try to remux your file with TSMuxer tool (Tsmux/h264/ac3/sub), and then change/force fps value on "General Track options" tab ?

I drop the file onto tsMuxerGUI and get this error -
---------------------------
Unsupported format
---------------------------
Can't detect stream type. File name: "E:\Video\Test\Aspect\Cats And Dogs.m4v"
---------------------------
OK
---------------------------
Presumably because it is a mp4 file - I could remux it into mkv first I guess. I'll let you know how that goes.

Yep

Setting FPS to 25 worked! (I suspect any FPS setting other than 90000 would).
I even had a video my Viera wouldn't play (it played all the other 10 or so) which got sorted by doing this remux. Wish I had thought of trying it myself.
I did have one mkv TSMuxer wouldn't read - gave me

But that's OK - actually scrap that, file has a constant Frame rate.

Sadly, in a lot of cases, the files still need transcoding on the Bravia anyway because the aspect ratio >16:9: viewtopic.php?f=5&t=5403&p=68524#p68524 and for the Viera they need remuxing back into mkv or mp4 for the same reason.
