Is MC genuinely usable for video on linux?

<< < (7/7)

JimH:
For what it's worth, I watched a couple of movies last night without serious problems, on the IdVR.  12th gen NUC with i3 CPU.  No hardware acceleration.  JRVR.  MC 30.0.83  Blu-ray rips.

MC30 was serving the mkv files from a Win10 machine running MC 30.0.87.  Wired connection.

I think the most obvious area where it still struggles is with repeated seeks, e.g. tap right arrow n times. This is really quite slow to respond to the extent you wonder if it is frozen. It doesn't crash or do anything else unpredictable though so it is at least stable/consistent behaviour.

The observed behaviour in this case is like the keypresses aren't debounced/coalesced i.e. I seek forward x second n times, it does n +x second seeks as opposed to 1 or 2 seeks (depending on debounce period and how quickly I press the button). It's certainly much slower than clicking somewhere on the track to jump forward. For me, this operation is more common than a big jump so I'd say this would be a good thing to improve for the end user.

Just for the extra reference point, can you try with Video buffering set off (Media Network Options)?
It reduces the complexity of the seeking (if it works at all which is the main reason video buffering is implemented).

That option is irrelevant for the kind of streaming being used for converted video.

It bypasses the disk buffering code?

Hendrik:
Yes, it hands the stream directly to FFmpeg with no additional buffering.
