Docker + ffmpeg 4.3 broken

[evilworm]

I have Unifi Cloud Key Gen2 and wanted to have my Hikvision camera displayed in my Viewport. Tried the dockerised unifi-cam-proxy version, but I could only get the snapshot image displayed however live streaming did not work. After digging around I found out that the Dockerfile pulls in ffmpeg 4.3 which unfortunately does not work for some reason... running ffmpeg on the stream outputs this:

I tried running the same ffmpeg command locally and it worked. I compared ffmpeg versions and found out that I have 3.4 and docker image has 4.3. Modified the Dockerfile to the following:

FROM jrottenberg/ffmpeg:3.4-ubuntu
WORKDIR /app

RUN apt-get -y update && apt-get install -y \
  python3 \
  pip \
  netcat-openbsd

COPY . .

RUN pip install .

COPY ./docker/entrypoint.sh /

ENTRYPOINT ["/entrypoint.sh"]
CMD ["unifi-cam-proxy"]

... and then docker-compose build && docker-compose up and I got the live image on my viewport

It would probably be a good idea to have fixed ffmpeg version in the Dockerfile apt-get part

hope this helps someone having similar issues...

@evilworm, I have exactly the same issue. I only see the "still" image, but no streaming. I tried your modified docker file, but it did not help. I verified that I really have ffmpeg version 3.4

Did you change something else in addition?

Docker-compose fix will help the video to be transfered to unifi protect however it seems that there are some other issues too 1) I get live video on my Unifi Viewport 2) I dont get live video in web UI, it just keeps "loading" forever 3) I have live video on my phone application 4) on the phone - when scrolling/seeking video to some specific time, it will not play the video but shows still image ... on desktop web ui it does not seek the video at all
