tried with and without sudo, tried changing rtsp ://... to http://
also tried udp but get same output..


chacked that the port is not in use(8888) and different ports (1935...) but still the same.


i installed ffmpeg via brew install...


when i run some test server on my localhost i never have issues ussing an unused port


really stuck here and any help would be amazing...thank you


EDIT :
Problem was in the command i used : "rtsp ://127.0.0.1:8888/live" - but i did not have a running server capable of accepting the data from ffmpeg and redestributing it - so i had to first run such server and only after that to run ffmpeg :


Servers which can receive from FFmpeg (to restream to multiple clients) include ffserver (linux only, though with cygwin it might work on windows), or Wowza Media Server, or Flash Media Server, Red5, or various others. Even VLC can pick up the stream from ffmpeg, then redistribute it, acting as a server.


i used the VLC option. You can read about it here : http://trac.ffmpeg.org/wiki/StreamingGuide

ffmpeg video won't play in certain players
25 janvier 2021, par Thomas TiottoI'm generating a video in
/folder/
from a stack of images in/folder/tmp/
using the following command :

ffmpeg -pattern_type glob -i 'folder/tmp/*.png' -c:v libx264 -preset veryslow -crf 17 -tune stillimage -y -pix_fmt yuv420p folder/weight_evolution.mp4



but my video won't play in, for example, QuickTime ("The file isn’t compatible with QuickTime Player.") and even sending it in Telegram gives really strange results. The video plays fine in IINA and VLC.


As you can see, this is what is encoded by Telegram :




and this is what the video should look like :




The output of the command is :


ffmpeg -pattern_type glob -i 'tmp/*.png' -c:v libx264 -preset veryslow -crf 17 -tune stillimage -y -pix_fmt yuv420p weight_evolution.mp4
