RTSP stream from container to the host

[Igor Ok]

Hi all,

I have some problemes with streaming video from dokcer container to the host.

For test case i streamed a video from the host to the same host as follows:

1) Working code (stream to the same host: 127.0.0.1 --> 127.0.0.1)

streamServer.sh:

find ~/.config/vlc -delete

vlc --play-and-exit -I dummy -vvv GoPro_HERO6_Surfing.mp4 --file-caching 300 --start-time 31.000 --sout "#transcode{vcodec=h264,acodec=mpga,scale=Auto,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://localhost:1234/stream}" --sout-all --sout-keep

streamClient.sh:

wait 7s

vlc -vvv rtsp://localhost:1234/stream

Now i use the same code to stream the same video from container to the host but it fails.

2) Not working code (stream from container 172.18.0.2 --> to the host docker0 172.18.0.1)

Docker Container side:

Dockerfile:

# Use an official Python runtime as a parent image

FROM python:2.7-slim

WORKDIR /astream

ADD . /astream

COPY gopro.mp4 /astream/

COPY startStream.sh /astream/

RUN useradd -m vlc

RUN apt-get update && apt-get install -y vlc

EXPOSE 1234

ENTRYPOINT ["/astream/startStream.sh"]

startStream.sh:

#!/bin/bash

find ~/.config/vlc -delete

name=$SCRIPTPATH"/gopro.mp4";

sout="#transcode{vcodec=h264,acodec=mpga,scale=Auto,ab=128,channels=2,samplerate=44100}:rtp{sdp=rtsp://172.18.0.1:1234/test}"

# su vlc -> here vlc is a user name (created in Dockerfile)

su vlc -c "vlc --play-and-exit -I dummy -vvv $name --file-caching 300 --start-time $1 --sout '$sout' --sout-all --sout-keep"

Host side:

streamClient.sh

vlc -vvv rtsp://$1:1234/test

This part is not working. With wireshark i can not even see any incomming packets on docker0.

Can anyone help me with that?

Thanks in advance.
