QUESTION

Docker: random Alpine packages fail to install

Asked 2021-Nov-22 at 14:18

Context

I have a jenkins that builds a docker image for a raspberry pi 2. It is using buildx to emulate the ArmV7 environment during build. This worked great until recently I got random errors during installing the apk packages.

ok, looks like i found my solution here: https://gitlab.alpinelinux.org/alpine/aports/-/issues/12406

quote from Lyle Franklin:

I hit this error when trying to build a cross-platform ARM64 docker image from a AMD64 host. However, running docker run --rm --privileged linuxkit/binfmt:v0.8 or update-binfmts --enable prior to running the build seems to avoid the issue. My understanding Docker will try to use upstream QEMU if it is installed and registered with the kernel, otherwise Docker will fallback to using a built-in forked version of QEMU. The build error above only showed up for me with the forked QEMU.

So I will probably add docker run --rm --privileged linuxkit/binfmt:v0.8 && update-binfmts --enable to my pipeline file if I encounter the error again, for now running it once solved the issue.

ALSA dsnoop causes issue with GStreamer video

Asked 2021-Apr-25 at 00:53

I am using GStreamer to stream live video / audio from a Pi3B with a picam module and USB microphone. My end goal is to use the audio from the one USB microphone in both the live video / audio stream AND as the input to a python script. I understand that this can be done with the ALSA dsnoop plugin and have been able to demonstrate it with this /etc/asound.conf config:

For posterity, I received a great tip from the GStreamer developer forum.

Adding provide-clock=false to the alsasrc line did the trick! so the GStreamer call becomes:
