Stream from simulator appears distorted  #867

Description

The iOS simulator stream encoded by ffmpeg and played by VLC appears distorted. I need to automate IOS device and view it live inside my application but the stream appears distorted when displayed.

Reproduction

Start an idb companion on grpc port 10082.

idb_companion --udid 48DC4B33-CF71-42EA-BED9-5461FF48EF3C --grpc-port 10082

After that start a stream for iphone 15 simulator piped to be played by VLC via ffmpeg.

idb --companion localhost:10082 video-stream --format rbga --fps 6 --udid 48DC4B33-CF71-42EA-BED9-5461FF48EF3C | ffmpeg -f rawvideo -pix_fmt rgba -s 1178x2556 -r 6 -i - -vcodec libx264 -tune zerolatency -f mpegts - | vlc - --network-caching=1000

Expected Behaviour

A visual stream like this.
