• Two rtsp streams to youtube on a Pi3

  19 mars 2020, par Sébastien Bonaimé

  I want to stream two rtsp camera from my birdbox to youtube from my raspberry pi 3 with the entrance in Pip (picture in picture) on top left. I don’t need sound.

  192.168.1.13 can do 30 fps with sound that I don’t need
  192.168.1.31 is only 12 fps without sound

  I have some problems of lag between the two camera on the youtube stream which I think is due to the different fps. I compile ffmpeg with h264. Here is what I did

  ffmpeg -re -f lavfi -i anullsrc -rtsp_transport udp -thread_queue_size 1000k -i rtsp://admin:123@192.168.1.13:554 -i rtsp://admin:@192.168.1.31:554 -filter_complex "[1]scale=iw/4:ih/4[pip]; [2][pip] overlay=0:0"   -framerate 13  -bufsize 512k  -b:v 1500k -threads 4 -q:v 3  -c:v h264_omx  -c:a aac -f flv rtmp://a.rtmp.youtube.com/live2/XXX-XXXX-XXX

  and here are the errors

  [h264 @ 0x20ddd30] error while decoding MB 69 67, bytestream -6rate=1589.2kbits/s dup=0 drop=6 speed=0.997x

  [rtsp @ 0x1f2cea0] max delay reached. need to consume packetbitrate=1588.9

  What can I do to improve the stream ? When a bird enter the box, there is also a quality problem when the image is changing and some lagging.

• 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.
