Configuration appearing to be ignored in docker

Which version are you using?

Architecture

• amd64
• arm64
• arm7
• arm6

Describe the issue

I am mounting a volume with a configuration in it that works locally. Once the volume is mounted it appears to be picked up because the container runs and stars putting out logs. It also says reloading configuration if I edit the config, so im quite sure it is getting the configuration. When I connect a stream to it it says connected and is publishing to path and everything looks fine except it isnt running my command in runOnPublish

Its strange because if I just download the binary and run it it with this same config it works perfectly. The current content in runOnPublished uses ffmpeg to output a file but it also does nothing in the container if i replace it with very simple things like echo 'cat'

Describe how to replicate the issue

1. Make a directory and put the attached config.txtfile in it (rename it to config.yml because GitHub wont let me attach a .yml file. config.txt
2. cd into the directory and run docker run --rm -it -e RTSP_PROTOCOLS=tcp -v ${PWD}:/app -w /app -p 8554:8554 aler9/rtsp-simple-server ./config.yml

Super awesome project btw, thank you so much :D

Hello,

1. I've added to the README the right command to replace the configuration file when using Docker
   https://github.com/aler9/rtsp-simple-server#configuration

2. anyway, this is not your issue: the issue is that you're trying to use ffmpeg, but the Docker image doesn't contain ffmpeg, since there would be license issues and the image would become huge. You have to generate an image that contains both rtsp-simple-server and ffmpeg, in this way

FROM aler9/rtsp-simple-server AS rtsp
FROM alpine:3.12
RUN apk add --no-cache ffmpeg
COPY --from=rtsp /mediamtx /
COPY --from=rtsp /mediamtx.yml /
ENTRYPOINT [ "/mediamtx" ]

[Tuxie]

Yes, you should be able to run this inside the same container that is running rtsp-simple-server. If you run it in a separate container you need to replace "localhost" with the ip of the rtsp-simple-server container.

Hmmm I didn't thought about that... So I would have to run on the producer's terminal (Windows host): ipconfig /all and identify the one that says IPv4 address?
Thank you very much for the help! It has been of great value

[aler9]

I don't think it's possible to access raw devices from within WSL (1 or 2)

Exactly. Docker on Windows uses a Linux virtualization layer (WSL) that doesn't expose most of the devices (GPU, devices, etc). Use the native version or use VirtualBox/VMware, that have better hardware support.

I must be crazy, I can't get this Dockerfile to build. Every time I get an error at the COPY that /rtsp-simple-server doesn't exist:

[stage-1 3/3] COPY --from=rtsp /rtsp-simple-server /:

---

Dockerfile:4

2 | FROM alpine:latest
3 | RUN apk add --no-cache ffmpeg
4 | >>> COPY --from=rtsp /rtsp-simple-server /
5 | ENTRYPOINT [ "/rtsp-simple-server" ]
6 |

ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref moby::xfr910rkjvqzsu5993k99ru85: "/rtsp-simple-server": not found

[aler9]

@noneabove1182 the executable was renamed into /mediamtx since v0.22.0, so you have to change /rtsp-simple-server into /mediamtx

[AndBondStyle]

@aler9 maybe you can CI-build an alternative docker tag with ffmpeg included? That would be very convenient

FYI, in addition to ffmpeg I also added libva and mesa-va-gallium to the Dockerfile to get amd/radeonsi vaapi hardware acceleration working. Used the docker instructions from Frigate to add the /dev/dri/renderD128 device and set LIBVA_DRIVER_NAME=radeonsi

[AdiAbuAli]

can you please share the syntax in docker file to enable HW accelerator?

[Tuxie]

This is my full Dockerfile for AMD GPU hardware acceleration. For Intel or Nvidia you will need some other packages.

FROM aler9/rtsp-simple-server AS rtsp
FROM alpine:latest
RUN apk add --no-cache libva mesa-va-gallium ffmpeg
COPY --from=rtsp /rtsp-simple-server /
ENTRYPOINT [ "/rtsp-simple-server" ]

Then in my docker-compose.yml I have

    privileged: true
    devices:
      - /dev/dri/renderD128
    environment:
      LIBVA_DRIVER_NAME: "radeonsi"

and I believe the docker cli equivalents are --privileged --device /dev/dri/renderD128 --env LIBVA_DRIVER_NAME=radeonsi

[AdiAbuAli]

Thanks ....What was the FFMPEG command you used?

For example this one to transcode a large high bitrate video to a smaller low bitrate mobile version:

  baksidan-mobile:
    runOnDemand:
      ffmpeg -hide_banner -loglevel info
      -hwaccel vaapi -hwaccel_output_format vaapi -hwaccel_device /dev/dri/renderD128
      -avoid_negative_ts make_zero -fflags +genpts+discardcorrupt -flags low_delay
      -stimeout 5000000 -rtsp_transport tcp
      -i "rtsp://127.0.0.1/baksidan"
      -vf "scale_vaapi=w=1280:h=720" -c:a copy -c:v h264_vaapi -b:v 768K
      -f rtsp rtsp://127.0.0.1/$RTSP_PATH
    runOnDemandRestart: yes

[AdiAbuAli]

Thank you dear..I tried allpossible configurations but all failed with device creation failure -12
I opened question thread in Synology

[gLuColte]

Sorry where does this go to?

I am trying to build a single docker that streams local file (video within rtsp-simple-server docker) to a port.

Can this work?

What I want to achieve is a single docker that incooperates rtsp-simple-server and ffmpeg, incooperating with a shell script that fetches video from online storage bucket.

When using this I'm getting a:

ffmpeg: error while loading shared libraries: libblas.so.3: cannot open shared object file: No such file or directory
