Segmentation fault on Tinycam connecting to Neolink - E1 pro

[aleqcz]

Describe the bug
Segfault immediately after connecting Tinycam mobile app. VLC with same url works

To Reproduce
Steps to reproduce the behavior. Example:

1. Create this configuration file:

# A bind value of 0.0.0.0 means any network this computer can access
# You can chage this to a specfic network e.g. "192.168.1.101" here
# Or to no networks e.g. this computer only "127.0.0.1"
bind = "0.0.0.0"
# Default port is 8554 but you can change it by uncommenting the following
# bind_port = 8554

# Uncomment the following and supply a path to a valid PEM
# to activate TLS encryption.
# The PEM should contain the certificate and the private key
# If TLS is activated you must connect with "rtsps://" and not "rtsp://"
# certificate = "/path/to/pem/with/cert/and/key"

# You can password protect the rtsp server mount points by adding users
# like the following me and someone. If you do not add [[users]]
# then anyone can connect without a password or username
# To access such a stream try using a url such as "rtsp://me:mepass@192.168.1.101/driveway"

[[users]]
name = "admin"
pass = "..."

# [[users]]
# name = "someone"
# pass = "someonepass"

[[cameras]]
name = "e1"
username = "admin"
password = "..."
address = "192.168.1.82:9000"
# stream = "mainStream"
stream = "both"
format = "h264"

2. Launch Neolink (dockerized): docker-compose up

services:
    neolink:
        ports:
            - '8554:8554'
        restart: always
        volumes:
            - '$PWD/config.toml:/etc/neolink.toml'
        image: thirtythreeforty/neolink
        environment:
            - GST_DEBUG=3

3. Connect Tinycam with following settings

@thirtythreeforty we have had a few duplicate issues about this docker segfault now. Should we add a note in in the docker section of the readme about this know issue?
