Will updating FFMPEG break my current setup?

[zerofell]

Here's the context. 
I am running  via Windows server. I am playing back on a Roku 4K Streaming stick and an Onn Roku 75" 4K TV
98% of my files will playback without any issue.
2% will either give a playback error or give a black screen.

After much searching from the old Reddit threads, I think the issue is transcoding from the box to the player. This 2% are Dual Audio 10 bit files (the only thing I can think of that is different from my other 1080 files)

Here's the question:

As I am running FFMPEG 5.1.3-3, if I were to upgrade to the current 6.0.4 release, will this break my setup overall? My reasoning for updating is to eliminate the transcoding bit all together. Newer decoder package, updated file info, thus easier playback. I haven't excused that this may be a Roku limitation by any means, but I just want to verify and the like, Feel me?

The ffmpeg logs in C:\ProgramData\Jellyfin\Server\logs would tell us more.

ffmpeg 5.1.3 supports 10-bit video and multi audio stream files. But does your hardware? What are your server specs?

[Shadowghost]

Are those files h264 10 bit aka Hi10p by chance?

[zerofell]

I think I got the pertinent data here ... I cleared all the logs and started one of the files that's having the issue ..

I should also point out .. as I just tested this ... the files play just fine via the web client in my Opera browser ...

[TheDreadPirate]

I just noticed this bit.  Emphasis mine.

....

My reasoning for updating is to eliminate the transcoding bit all together. Newer decoder package, updated file info, thus easier playback. I haven't excused that this may be a Roku limitation by any means, but I just want to verify and the like, Feel me?

Upgrading ffmpeg will not eliminate transcoding.  Since ffmpeg only runs when transcoding is occurring.  I also noticed in your log that you are software transcoding instead of hardware accelerated.

You said your server is on Windows.  Which version of Windows, what are the hardware specs, and what do your transcode settings in Jellyfin the dashboard look like? Settings > Dashboard > Playback.

---

One more thing. In the log directory, the "log_(date).log" file will contain the "TranscodeReason". That will help us figure out why these 2% of files are transcoding while the other 98% are direct playing.

[zerofell]

And here is the log from the other known fie giving me grief ....

We just cross paths. See my post above yours.

frame= 796 fps= 19 q=31.5 size=N/A time=00:00:33.18 bitrate=N/A speed=0.778x

Because you are software encoding, you are not keeping up. Slower than the real time.

If your library is entirely H264, you should have hardware acceleration enabled.  I'm pretty sure Kepler supports pretty much every profile H264 has.

You should have the following codecs checked for hardware decoding.

H264
MPEG2
VC1

And "Allow encoding in HEVC format" should be UNchecked.  Since the 750TI doesn't support accelerating that and your CPU is not fast enough to encode that in software.
