• Could not find codec parameters for stream 0 (Video : hevc, none) : unspecified size

  5 avril 2020, par bzc0fq

  I try to use ffmpeg to feed ffserver on CENTOS 6.10. When I run ffmpeg on stream I got an error message : Could not find codec parameters for stream 0 (Video : h264, none) : unspecified size.

  



  The full ffmpeg output is here :

  I tested the stream with vlc on windows and it looks it works fine.


  



  Any hints on the issue ?

• ffmpeg video&audio streaming from webcam

  23 février 2016, par johncarrie

  I am new to ffmpeg and I want to stream webcam video&audio by using ffmpeg and ffserver.

  ffserver config is the following :

  <stream>
  
  Feed feed1.ffm
  
  Format avi
  
  VideoSize 176x128
  
  VideoFrameRate 15
  
  VideoBufferSize 40

  AudioChannels 1
  
  AudioSampleRate 11025
  
  VideoQMin 1
  
  VideoQMax 20
  
  NoDefaults
  
  </stream>

  ffmpeg process is the following :

  ffmpeg -vcodec mjpeg -v verbose -r 15 -s 176x128 -f video4linux2 -i /dev/video0 -f

  I am using a FEBON168 UVC HDMI GRABBER CARD as Webcam.

  1. MJPEG 1280x720 up to 30fps (full screen)
  2. YUV 1280x720 up to 10fps (full screen)

  How can I fix it ? What am I doing wrong ?
