• Send a file and parameters to a OpenFaas Dockerfile function

  29 juillet 2021, par Johannes Klauß

  I have a ffmpeg Dockerfile function that I deploy to my OpenFaaS :

  


  FROM ghcr.io/openfaas/classic-watchdog:0.1.5 as watchdog

FROM jrottenberg/ffmpeg:4.1-alpine

RUN mkdir -p /home/app

COPY --from=watchdog /fwatchdog /usr/bin/fwatchdog
RUN chmod +x /usr/bin/fwatchdog

# Add non root user
RUN addgroup -S app && adduser app -S -G app
RUN chown app /home/app

WORKDIR /home/app

USER app

# Populate example here - i.e. "cat", "sha512sum" or "node index.js"
ENV fprocess="ffmpeg"
# Set to true to see request in function logs
ENV write_debug="false"

EXPOSE 8080

HEALTHCHECK --interval=3s CMD [ -e /tmp/.lock ] || exit 1

CMD ["fwatchdog"]


  


  But I cannot figure out how I would be able to stream a file to the function and give parameters, so that ffmpeg knows about the file and parameter.
I am fairly new to OpenFaaS and maybe this is trivial, but I cannot wrap my head around it.

  


  Any help would be much appreciated.

  Im trying to reduce a video.mov file (taken with canon dslr).
  Im using x264 like so :

  x264 -o '/home/user/Desktop/MVI_0390.mp4'  '/home/user/Desktop/MVI_0390.MOV'

  And Im getting following error :

  avs [error]: failed to load avisynth

  It seems that it was unable to find openjpeg.h and searched in folder openjpeg-2.0 to openjpeg-2.3. However, when I checked /mxe/usr/i686-w64-mingw32.static/include/, it contains openjpeg-2.4.

  


  The log for /mxe/log/gdal_i686-w64-mingw32.static is present here.

  


  Please help fix this. Thanks.
