• ffmpeg rtsp stream to YouTube livestream not doing anything

  29 mai 2018, par felixosth

  I’m using C# to initiate ffmpeg. I’ve a onvif bridge server for a CCTV VMS and I’m building a application to enable the user to livestream any CCTV camera to YouTube.

  The rtsp stream to the camera looks like this :

  rtsp ://onvif:bridge@localhost:554/live/xxxxx-xxxguidtocameraxxx-xxxxx

  I’m new to ffmpeg and I’m using this arg :

  -f lavfi -i anullsrc -rtsp_transport udp -i camerastreamurl -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://x.rtmp.youtube.com/live2/streamkey -loglevel debug

  It seems like ffmpeg isn’t finding the camera stream, only the fake audio one. It just freezes.

  This is the result of the debug log :

• using ffmpeg from macOS terminal for uploading youtube short from android just do nothing

  25 juin 2023, par Yogi Arif Widodo

  my component / recording is using blachole plugin on macOS.

  


  engine : 13" Macbook Pro M1 ( macOS 13.2 / Ventura )

  


  step to reproduce

  


  

  1. my output is screenRecordingAudio ( this name is custom name ).

  


  


  // screenRecordingAudio in audioMidi : 
BlackHole 16ch [mark as checked on use]
External Headphones [mark as checked on use]


  


  


  screenRecordingAudio is using on by click on right top of bar UI, click sound, click screenRecordingAudio.

  


  


  OR

  


  


  screenRecordingAudio is using on Settings ➡️ Sounds ➡️ Output ➡️ then choose screenRecordingAudio

  


  


  

  2. my input is quickTimeInput ( this name is custom name ).

  


  


  // quickTimeInput in audioMidi : 
BlackHole 16ch [mark as checked on use]


  


  

  3. then using ⌘ + shift + 5 , on option i use quickTimeInput

  


  4. i use these command to convert into mp4 and also purpose to get more small size video

  


  


  #!/bin/bash

# greet the user
function yoVideo() {
  ffmpeg -i $1.mov -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -movflags +faststart $1.mp4
}


  


  OR

  


  ffmpeg -i yogiarifwidodo.mov -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -movflags +faststart yogiarifwidodo.mp4


  


  

  5. then i move the video into my phone android.

  


  6. then when i tried to upload on youtube as short, its cannot be process to upload ( its just do nothing ) but when i upload on facebook reels its work also on instagram story its still working also for whatsapp story.

  


  


  when i didnt convert into mp4 its also happend and in any other case for example whatsapp story , its lagging to review video before upload . its happend to on instagram .
but when i force upload , the result video is good and smooth . then i re download my video its still best video and when try to upload my download video , there is no lagging in any condition.

  


  how to get ffmpeg perform into mp4 and also no lagging on editing while uploading at whatsapp story or instagram story or facebook , etc ?
by the way i dont know command ffmpeg , the code is copied from stackoverflow and i forgot where is it.

  


• Converting mp4 file downloaded via youtube-dl from periscope by using ffmpeg gives error

  20 mars 2018, par MonsterMMORPG

  This is command i have used to download from periscope by using latest youtube-dl

  youtube-dl -v periscopeurl

  Then i am running this command to convert it to a proper MP4

  ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4

  I am using latest youtube-dl and ffmpeg

  The error i am getting is shown below

  So how can i fix this error ? The file can not be played properly on k lite mega codec player but it can be played on vlc player however can not go to any specific time etc. so it really needs to be properly re-encoded

  C:\temp>ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4
