Hello Mozilla!
Ive been struggling for over 1 week trying to get the Codec Support Information field in about:support to populate with codecs/decoders. Sometime ago i did have it displaying AAC,MP4,etc. but i cant figure out what i did before that im not doing now.
Perhaps it could be some setting in about:config that i touched?
Im running Firefox ESR v115 source on Ubuntu 24 inside Docker.
I have built firefox with ac_add_options --enable-ffmpeg but codecs/decoders are not showing up.
Previously , some weeks ago, i had codecs showing without me using the ac_add_options --enable-ffmpeg build option.
prior to build, i installed:
apt install -y
libavcodec-dev
libavformat-dev
libavutil-dev
libswresample-dev
libswscale-dev
Also previously i tried getting GStreamer to work/show codecs to no luck.
apt install -y
gstreamer1.0-tools
gstreamer1.0-libav
gstreamer1.0-plugins-base
gstreamer1.0-plugins-good
gstreamer1.0-plugins-bad
gstreamer1.0-plugins-ugly
apt install -y dbus dbus-x11 xdg-utils
i remember i verified via:
gst-inspect-1.0 --version
gst-inspect-1.0 avdec_h264 | head
gst-inspect-1.0 faad | head
and it was installed, yet no codecs were showing up in about:support
in about:support i only see: Configure options --enable-application=browser --without-wasm-sandboxed-libraries --disable-updater --disable-crashreporter --enable-official-branding
yet i did this last build with ac_add_options --enable-ffmpeg.
What am i missing?
What could i try?
Im beyond frustrated with this. Its not working and i dont know why….
Please can somebody shed some light?!
Perhaps running an older Firefox source would be better? because there are many ac_add_options flags that are not available on this version. Previously i also remember i needed IOUtils but it doesnt come with this version.
