Running Docker image with Membrane RTMP Plugin

Hello, I am trying to run a Docker container with membrane_rtmp_plugin library, it builds successfully, however I am getting following error:

I've seen similar kind of error related to bundlex in this group, however I am not using Bundlex and it seems to be another kind of error.

membrane_rtmp_plugin uses bundlex under the hood. What image are you using? Are there any warnings from building the rtmp plugin?

oleg.okunevychOP•2y ago

thanks for quick answer 🙂

membrane_rtmp_plugin uses bundlex under the hood.

membrane_rtmp_plugin uses bundlex under the hood.

Does it mean that BundlexProject module is required to be configured in the application? I am using elixir:1.16.2-otp-26-alpine image. There are no warnings when building rtmp plugin:

#24 149.7 ==> membrane_rtmp_plugin
#24 149.7 Bundlex: Building natives: rtmp_sink

For Alpine and other systems that use MUSL instead of GLIBC, we unfortunately don't provide precompiled C deps, so you need to manually install them in the system or use a different image, for example debian-based. See https://github.com/membraneframework/membrane_rtmp_plugin?tab=readme-ov-file#manual-instalation-of-dependencies

That's weird you don't get any warnings though 🤔

for build stage following libs are used:

RUN \
  apk add --no-cache \
  build-base \
  git \
  npm \
  make \
  cmake \
  openssl-dev \
  libsrtp-dev \
  libsrt-dev \
  ffmpeg-dev \
  fdk-aac-dev \
  opus-dev \
  openssh-client \
  ca-certificates \
  curl

RUN \
  apk add --no-cache \
  build-base \
  git \
  npm \
  make \
  cmake \
  openssl-dev \
  libsrtp-dev \
  libsrt-dev \
  ffmpeg-dev \
  fdk-aac-dev \
  opus-dev \
  openssh-client \
  ca-certificates \
  curl

for app stage we have:

RUN \
  apk add --no-cache \
  libstdc++6 \
  openssl \
  libsrtp \
  ffmpeg \
  fdk-aac \
  opus \
  openssh-client \
  curl \
  ncurses \
  mesa \
  mesa-dri-gallium \
  mesa-dev

RUN \
  apk add --no-cache \
  libstdc++6 \
  openssl \
  libsrtp \
  ffmpeg \
  fdk-aac \
  opus \
  openssh-client \
  curl \
  ncurses \
  mesa \
  mesa-dri-gallium \
  mesa-dev

Mateusz Front•2y ago

possibly you need ffmpeg-dev for the app stage as well? not sure what apk installs

oleg.okunevychOP•2y ago

still the same results. What other Docker image would you suggest to try?

Mateusz Front•2y ago

you can try the same name but without the alpine suffix

oleg.okunevychOP•2y ago

I think I found the problem, error dissapeared after updating app alpine image from alpine:3.17 to alpine:3.18.5 Thank you for help!
