• ffmpeg streamaudio video webcam raspberry pi

  5 novembre 2015, par user3291059

  I’m using a webcam on my Rpi to record audio video. I’m using ffmpeg
  and here is my command :

  ffmpeg -y -ac 1 -f alsa -i hw:1,0 -i /dev/video1 -r 10 -s 120*120 -async 1 -strict -2 -c:a aac -pix_fmt yuv420p -threads 0 -ar 44100 -f mpegts out.avi

  This generates a .avi file with video and audio however when I try to stream using ffserver using :

  ffmpeg -y -ac 1 -f alsa -i hw:1,0 -i /dev/video1 -r 10 -s 120*120 -async 1 -strict -2 -c:a aac -pix_fmt yuv420p -threads 0 -ar 44100 -f mpegts http\\some_ip:someport\webcam.ffm

  I get av_interleaved_write_frame(): Broken pip

  How I can fix this ? Any other suggestion to stream audio video (not with Motion please).

  UPDATE

  here is my ffserver config file

      Port 8090
  
  BindAddress 0.0.0.0

  when I save the stream to a local file out.avi I can see video and audio but when I use ffserver vlc on my windows machine is not even able to display video (black screen with some sound glitches from time to time)
  Thanks.

• How do you pipe video from one tool to another on Raspberry Pi ? [closed]

  11 septembre 2024, par Spenser Spratlin

  I'm trying to pipe video from libcamera to ffmpeg to get a consistent video stream from a Pi Camera Module 2 to a Java Program

  


  I'm using the following

  


  

  • OpenJDK/JRE 17

  


  • Raspberry Pi 5 Model B

  


  • Debian 12 (bookworm)

  


  • Arm64

  


  


  Since Raspberry Pi changed their video framework, you can no longer call a single /dev/video0 device. You have to go through the Media Controller using libcamera or rpicam. I'm wondering how I can pipe the video created from libcamera or rpicam into a useable format to intake with ffmpeg.
