rtmpdump project rtmpdump DOWNGRADE

Affected: 2.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.4

1. Check installed version

apt-cache policy rtmpdump || rpm -q rtmpdump || rtmpdump --version

2. No fixed release: DOWNGRADE to a release before 2.4 (Debian / Ubuntu)

apt-cache madison rtmpdump sudo apt install rtmpdump=<VERSION_BEFORE_2.4> sudo apt-mark hold rtmpdump

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list rtmpdump sudo dnf downgrade rtmpdump-<VERSION_BEFORE_2.4> sudo dnf versionlock add rtmpdump

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
