I'm trying to record a browser in Docker container using the Aerokube images when in the browser some audio is being played (e.g., in a YouTube video or a WebRTC application). Is this possible?

The steps I made to try to achieve it are the following:

  1. Start Docker container:
docker run --rm --cap-add=SYS_ADMIN -p 4444:4444 -p 5900:5900 -e ENABLE_VNC=true selenoid/vnc:chrome_92.0
  1. Start recording (supposing that the address of the previous container is 172.17.0.2):
docker run --rm -v `pwd`:/data -e BROWSER_CONTAINER_NAME=172.17.0.2 -e FILE_NAME=myrecording.mp4 selenoid/video-recorder:7.1
  1. Connect to the browser container, start Chrome, navigate to YouTube, and reproduce some video.
  2. Stop the recorder container.

At the end of this process, I have the recording in the file myrecording.mp4, but this media file does not have audio track. Besides, I can see the following errors in the browser container:

I don't know the source of the first group of errors (Failed to connect to the bus: Failed to connect to socket). Any idea about that?

Then, it seems there are some problems related with the audio (ALSA lib confmisc.c:767:(parse_card) cannot find card '0').

Is there any issue in the browser (or recorder) or perhaps I am doing something wrong? Thanks in advance.

PS: Is this issue somehow related to #403?

@bonigarcia try more recent video recorder image.

@vania-pooh I though that version of selenoid/video-recorder was the latest, according to Docker Hub. If not is that, what is the latest version?

@vania-pooh

@bonigarcia in your example command you have: selenoid/video-recorder:7.1.

@bonigarcia

Yes, I though the tag 7.1 (uploaded 8 months ago) was the latest versions, since it is the greater number, and it is also the newest versions according to Docker Hub (even more than the tag latest-release, uploaded a year ago):

Do you mean that I should use latest-release tag instead? I am going to test with that version also.

@vania-pooh

@bonigarcia just checked. Should work with 7.1 and recent browser images. Please try with previous Chrome versions like 91.0. So far as we can see Chrome 92.0 have GPU-related issue. Not sure whether this influences sound recording.

@vania-pooh I have tried with Chrome 91.0, and different setups and recorders (7.1 and latest-release), but I didn't manage to record the sound. I have also tried to use in-memory filesystem (tmpfs) and shared memory, but still, no luck.

docker run --rm --cap-add=SYS_ADMIN -p 4444:4444 -p 5900:5900 -e ENABLE_VNC=true --mount type=tmpfs,destination=/tmp,tmpfs-size=512m --shm-size=1g selenoid/vnc:chrome_91.0

I think the problem is not in recorder, since the media info of the recording file shows an audio track (but it seems is basically silence):

@vania-pooh Any update regarding fixing it for the next release of chrome?

@GhaziTriki not yet. Instead of just summoning us to the issue, you could meanwhile do your own investigation. That's open-source.

@GhaziTriki

@vania-pooh I am not a sys admin expert. Since Aerokube implemented it I thought you would have a better idea about how to bring it back to the product, since having audio working is critical to have in Selenoid. We are planning to do some investigation of course.

For me with applying this fix for chrome made it.
Fixed nicely the audio in recordings: #646
I also updated the recording image build: #647

Looks like #646 fixed it for me!
