Universal Media Server | Forum

Hiya,

I'm on a 2015 iMac running Big Sur.

I realize that Mencoder is not particularly important & that I've generally been able to run most files I've needed through UMS but I still would like to fix this issue so that I know the system is optimized & that when I do run into issues it's not because Mencoder isn't being recognized.
I feel I've done everything I can to make sure Mencoder/Mplayer is installed properly & I have uninstalled/reinstalled multiple versions of UMS.. older versions up to the current beta.

On the Transcoding Settings page of UMS the Mencoder Video header (& Mencoder Web Video) have the warning symbol next to them & when selected the display shows:
"This engine is not loaded!
Transcoding engine MEncoder Video is not available because it failed with the following error:Unknown error"

I've dug through several web opages & forums trying to understand Mplayer/Mencoder & see if I should be doing something else to install them but all roads have led to "install through HomeBrew" which I have, apparently successfully, at least according to HomeBrew telling me it's installed. Also, I have verified that it is the latest version of Mplayer.

Any ideas? Thanks for any help.

I'm sure the issue is with apple no longer allowing certain programs running on their newest OS.
IIRC Mencoder is currently a 32 bit only program and these are being disallowed.

I think I have seen a better explanation on this forum somewhere but I believe that was the reason.

Thank you mik_s.

Spurred by your reply I did some searching & have seen peeps confirming that in no way is 32 bit supported anymore & I haven't been able to 100% confirm that Mplayer is 32 bit but obviously that seems very likely.

Best regards!

Our MEncoder for macOS should be 64-bit now unless you're using the "pre-10.15" build. Can you atach logs?

I do have the same issue and the logfile states an error whilst loading usr/local/opt/x264/lib/libx264.160.dylib
All was fine until I upgraded to V10.x lately. A downgrade to V9.x does not help

Ah that error message is helpful. That indicates that our version of MEncoder is not fully statically built, which is my fault, but in my defense it is really hard I'll try to fix it

Just as a follow up (but I guess you were not able to find a fix yet ) the issue is also present with the official 10.0.0 release.
If I could try to install something in the OS manually to narrow the root-cause down, let me know.

Thanks for confirming. I do intend to fix this, and will post in here when I have a test build

Hello
I have the same problem
Osx 11.2 (Big Sur)
UMS 10.0.1
and the error is
This engine is not loaded: Transcoding engine MEncoder Video is not available because it failed with the following error:Unknown error

I have installed the version "Universal Media Server macOS 10.15+ (disk image)"

Please help

I have started working on this. Will post when there's something to test
