I am wanting to buy some new hardware for a server but I hear that these particular files can be troublesome for lower power CPUs to transcode. (I believe it’s the only file format that the FFMpeg decoder doesn’t do multi-threading on?)
I would love to know if there’s plans to fix this by the FFMpeg team (I googled, it seems unlikely) or what third party Windows tool I can run to identify these files and see just how much of a problem I have, over my very extensive library.
Anyone got any ideas? (I found a few posts here about Intel Atom C2750 motherboards, many cores, quite cheap and powerful but single threaded stuff is mediocre and it can’t cut it)

Only the ffmpeg team can answer that.

ExportTools will export your libry(s) into a CSV file which you can sort and filter in a spreadsheet application. Among the exported data is also the codec (and a shedload of other info)

‘single thread rating’ needs to be at min. ~1350 points to be able to transcode a VC-1 video at 1080p and burn a PGS/VOBSUB subtitle into it.
Look up your prospective server cpu here http://cpubenchmark.net/
But no, an Atom won’t cut it.

Understand ffmpeg team would be the ones dealing with it, was curious if someone here was also following it closely.
I’ll check out the tool, thank you.
The Atom C2750 only gets a 579 on that chart unfortunately, thanks for the info. Is that a pretty fixed rule overall? Like 1600 points would be safe kind of thing?

Like I wrote: 1350 is the minimum to safely transcode VC-1 and burn in pixel-based subtitles. It is kind of a worst case.
(Unless we are moving to HEVC-encoded videos, that is. Then it gets much, much worse.)
Thanks for your help, I suspect I’m going to simply throw too much power at this.
I’ll wait till others on these forums and elsewhere try with the Denverton 4/8 core CPUs in 3 to 9 months, fingers crossed.
(It’s probably going to be a Xeon - D though, I suspect)
