unable to play some videos asking for some codec about docker-firefox HOT 5 CLOSED

I'm having the same issue, looks like we might need ffmpeg docker-mod for this docker image.

from docker-firefox.

@rahul1996pp figured out a workaround:

Using web page
open xterm by right-clicking outside firefox window in the web page and selecting xterm
run the following to install ffmpeg:
sudo apk add --update ffmpeg
restart firefox

Alternatively, inside the terminal get the container id and open bash and install package:
list docker containers, and make note of CONTAINER ID for firefox
docker ps -a
open bash for container
sudo docker exec -it <CONTAINER ID> bash
install ffmpeg package
sudo apk add --update ffmpeg

from docker-firefox.

You can use the container built in overrides to make this automatic.

Under the config directory for firefox, create a file called custom-cont-init.d/install_ffmpeg

with the contents like:
#!/bin/bash
echo "**** installing ffmpeg ****"
apk add --no-cache ffmpeg

Then ffmpeg will get installed automatically after upgrades, etc.

sudo apk add --update ffmpeg
