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.okunevych•4mo 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

mat_hek•4mo ago

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

oleg.okunevych•4mo ago

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

mat_hek•4mo ago

you can try the same name but without the alpine suffix

oleg.okunevych•4mo 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!
