Universal Media Server | Forum

I have had a holiday from UMS for some time because of unresolved issues but thought I would try it again with V11.5.0.
I am running UMS on a headless Linux server.

This issue is the same as previous versions after version 7.4. Up to V7.4 playing videos from a browser was OK.
Videos will not play using Firefox, Edge or Chrome.

Does anyone have any suggestions?
The log file in TRACE mode is attached.

Thanks

Is anyone else having problems running video files from a browser?
From my logs, it seems as though this might be an issue:

Guess I am going back on holidays again.

Sorry I missed this, not been on that often recently.
I think there may be something wrong with your FFmpeg installation as it does not understand the 'preset' option. I compared the FFmpeg command line used with what is used on my computer and it is almost the same and works fine. The only real difference is the extra options "-hwaccel auto -threads 1 -ss 18" in mine.
Since you are on Linux I don't really know how UMS is installed, if it installs FFmpeg itself or if you already had an old version on your computer that it chose to use instead and not update it.
The version you have installed is Where mine is using See if you can manually update it, or try deleting that version and reinstall UMS.
I'm not sure if UMS is using a custom build of FFmpeg for the HLS transcoding used for the web player.

Thanks for the reply.
After 2 years someone (yourself) has finally drilled down the issue.
I uninstalled ffmpeg (which is the latest stable Linux version) so UMS used its own included ffmpeg.
Watching videos from a browser worked fine after that,

Now to find out what is the problem with my Linux ffmpeg.

I will report back.

Thank you.

I got to the bottom of it.
The ffmpeg version included in UMS is a large file with support for xvid, x264 and x265 built in.
root root 50848812 Sep 6 09:20 /opt/ums/ums/linux/ffmpeg

The ffmpeg version with Gentoo Linux is a much smaller file and extra packages (eg: xvid, x264 and x265) have to be installed separately.

The UMS version has the following built in.

Before I installed the xvid, x264 and x265 packages and enabled them in ffmpeg, it was:
--disable-libx264 --disable-libx265 --disable-libxvid

It seems to be working fine now with just those 3 packages enabled in my Gentoo Linux ffmpeg.

Thank you for checking and giving me some direction with this.

Cheers

Glad that was it.

It was a hunch I had after seeing the command was the same but yours did not understand one of the options giving an error.
That option was probably only used for HLS in V11 so the main cause remained hidden in your previous logs.

I think if FFmpeg is already installed on Linux then it will take priority over the version UMS installs. I don't know enough to be sure though.

I'm sure I have seen that UMS uses a fork of FFmpeg for some features so that may be why the version you had appeared to be the latest and never got updated.

I found a bit in the UMS.conf that would allow you to tell UMS which version to use. Its in the "Non-GUI Options" section if you need to use the other version.

Yes, UMS uses the system ffmpeg by default unless configured otherwise.
Seeing as it seems to be working OK now I will leave UMS using the system ffmpeg.

Thanks again
