Disable IPv6 DNS lookup in gstreamer

Original problem: When reading HTTP streams using the gstreamer

( gst-launch

) command on a specific client network, I saw very often (not always) a 5 second initial delay before the stream started loading.

After some investigation, I discovered (with wireshark) that it was caused by DNS resolution issues and in particular AAAA (IPv6) requests failing (no response) at high frequency (on this network) and causing a wait and try again via 5 seconds.

I noticed the same problem when using "wget", but not with "wget ​​-4" because it doesn’t make AAAA requests.

Changing your network infrastructure is not an option. So I would like to know if it is possible to somehow skip the AAAA / IPv6 DNS lookup at startup gstreamer

like the wget option "-4".
