I do not use snaps at all, so please help me understand what you need.

First of all, the chromium ffmpeg snap provides the following versions of the codecs, which respectively match chromium's versions like so

ffmpeg version	chromium version
ffmpeg-92142	chromium 69
ffmpeg-92393	chromium 70
ffmpeg-92972	chromium 71
ffmpeg-93464	chromium 72

Right?

Second, you want to "connect" the proper codec version to each opera version, right? That means you will have to connect

opera (stable) > v58 > based on chromium 71 > ffmpeg-92972
opera-beta > v60 > based on chromium 73 > not available as it seems
opera-developer > v60 > based on chromium 73 > not available as well.

And third, in order to make the above connections, you have to do

for opera (stable)
snap connect opera:chromium-ffmpeg-92972 chromium-ffmpeg:chromium-ffmpeg-92972
for opera-beta
snap connect opera-beta:chromium-ffmpeg-XXXXX chromium-ffmpeg:chromium-ffmpeg-XXXXX
for opera-developer
snap connect opera-developer:chromium-ffmpeg-XXXXX chromium-ffmpeg:chromium-ffmpeg-XXXXX

where "chromium-ffmpeg-XXXXX" is the 5-digit number that would match chromium 73, but it is not available for the time being.

@jimunderscorep said in Broken autoconnection with chromium-ffmpeg in snap version:

proper codec version

It's error in opera snap packges.

Version	Based on Chromium	Interface names in snap packages (WRONG!!!)	Correct names for snap packages
Stable	71	chromium-ffmpeg-91124	chromium-ffmpeg-92972
Beta	73	chromium-ffmpeg-91124	chromium-ffmpeg-{XXXXX for 73}
Developer	73	chromium-ffmpeg-91124	chromium-ffmpeg-{XXXXX for 73}

And command for connection with wrong names is

snap connect opera:chromium-ffmpeg-91124 chromium-ffmpeg:chromium-ffmpeg-92972

And now it working because chromium-ffmpeg slots have been changed in snap store.

snap interfaces chromium-ffmpeg
Slot                                   Plug
chromium-ffmpeg:chromium-ffmpeg-91124  opera,opera-beta,opera-developer
chromium-ffmpeg:chromium-ffmpeg-91696  -
chromium-ffmpeg:chromium-ffmpeg-92142  -
chromium-ffmpeg:chromium-ffmpeg-92393  -
chromium-ffmpeg:chromium-ffmpeg-92972  -
chromium-ffmpeg:chromium-ffmpeg-93464  -

snap interfaces opera-developer | grep chromium-ffmpeg
chromium-ffmpeg:chromium-ffmpeg-91124  opera-developer

@adasiko - Your information was a key part of my solving my webcam problem.
just to add some details for others who may be less technical.
ever volunteered the solution in a simple form.

to make your webcam work in Opera browser:
(1st half of the solution:)
open your SNAPS (software) GUI
find Opera in the list of installed SW (click on it)
click on the Permissions tab
verify Opera is allowed to talk to your webcam & bonjour devices
(2nd half of the solution:)
in a terminal window enter
'snap interfaces chromium-ffmpeg'
it will give you a list, you need to patch the connections between the one listed as "opera" and the last one in the list
'snap connect opera:chromium-ffmpeg-95241 chromium-ffmpeg:chromium-ffmpeg-98516'
the numbers will be different depending on the various version you are using
*** it is okay if you use trial and error process to keep patching connections until it work.
