Does your mythbackend have libx264 support compiled-in?

Post by marigx » Mon Jan 20, 2020 5:49 pm

I'm exploring the HTTP Live Streaming server built-in to mythbackend.

At the wiki page for it states... "Your backend must have been compiled with "--enable-libx264 and --enable-libmp3lame" to support the H.264 video and MP3 audio used in the HLS streams generated by MythTV v0.25. Without those, you'll never get anything transcoded."

Ok since I am not getting any output when trying to use the live streams, I thought I should confirm that libx264 and libmp3lame support is actually compiled in to my copy of mythbackend:

Code: Select all

[user@host ~]$ mythbackend --version
Please attach all output as a file in bug reports.
MythTV Version : v30.0-v30.0-53-g6bd8cd4993
MythTV Branch : fixes/30

I see libmp3lame in that output, but no libx264. But according the folks at RPMFusion whose packages I use, the mythbackend rpm they build and distribute is indeed built with libx264 support. It's hard to argue with build logs.

If you have a minute, can you run "mythbackend --version" on your MythTV server, and paste the contents here? It would be helpful to see the output from some other installations, especially to know what platform and packager (or self-compiled?) is being used.

Thanks!

From ppa/30, and no libx264 here either, although both libx264-148 and libx264-152 re installed on my system. xubuntu 18.04LTS

FWIW, I don't see libx264 in the output of "mythbackend --version" either:

Code: Select all

mythtv@mythtv:~$ mythbackend --version
Please attach all output as a file in bug reports.

but it still seems to link against it:

Code: Select all

mythtv@mythtv:~$ ldd /usr/bin/mythbackend|grep libx264
	libx264.so.152 => /usr/lib/x86_64-linux-gnu/libx264.so.152 (0x00007fc3404e8000)
