  I’m getting an SAR error when using complex filters in ffmpeg and I can’t quite make sense of it. The input command is as follow (spread over multiple lines for clarity) :

  ffmpeg \
  
  -i '698cc30d2dc966eaf4dc4f6f3571df8d.mp4' \
  
  -i '76a2ffdd0d7e82d31731c6e2c0c6f4c9.mp4' \
  
  -filter_complex "\
  
      [0:v] setsar=sar=1,setpts=PTS-STARTPTS,scale=1080x1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2 [0v]; \
  
      [1:v] setsar=sar=1,setpts=PTS-STARTPTS,scale=1080x1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2 [1v]; \
  
      [0v][0:a][1v][1:a]concat=n=2:v=1:a=1[v][a]" \
  
  -map "[v]" -map "[a]" \
  
  -max_muxing_queue_size 500 \
  
  -strict -2 \
  
  out.mp4

  And I’m getting the following error :

  [Parsed_concat_8 @ 0x7fe35a70b100] Input link in1:v0 parameters (size 1080x1920, SAR 1:1) do not match the corresponding output link in0:v0 parameters (1080x1920, SAR 1216:1215)

  [Parsed_concat_8 @ 0x7fe35a70b100] Failed to configure output pad on Parsed_concat_8

  Error reinitializing filters !

  Failed to inject frame into filter network : Invalid argument

  Error while processing the decoded data for stream #1:0

  The complex filters basically scale the videos to the required dimensions (1080x1920) and add black borders below and above, or on the side to make it fit within the rectangle. It worked with some videos but not in this case for some reason and I can’t make sense of the error message.

  Any idea what it means and how to fix it ?

• Input link in1:v0 parameters (size XXX, SAR XXX) do not match the corresponding output link in0:v0 parameters (XXX, SAR 1:1) [duplicate]

  I’ve two files, a mp4 and a mp3 file. I want to add a 3 seconds intro screen with title Welcome and black background to the head of the video with the mp3 as background. So here’s what I wrote.

  ffmpeg \
  
      -i input.mp4 \
  
      -i bgm.mp3 \
  
      -f lavfi -i color=c=black:s="1280"x"544":d=3.0 \
  
      -filter_complex \
  
          "[2:v]
  
    drawtext=
  
      fontsize=30
  
      :fontcolor=white
  
      :x=(w-text_w)/2
  
      :y=(h-text_h)/2
  
      :text='WELCOME',
  
      geq=0:128:128
  
  [introVideo];
  
  
  
  [1:a]
  
      atrim=0.0:3.0
  
  [introAudio];
  
  
  
  [introVideo][introAudio][0:v][0:a]concat=n=2:v=1:a=1" -preset superfast output.mp4

  but am getting below error when I try to execute the command

  [Parsed_concat_3 @ 0x55c02756fa00] Input link in1:v0 parameters (size 1280x544, SAR 1299:1280) do not match the corresponding output link in0:v0 parameters (1280x544, SAR 1:1)

  Error reinitializing filters!
  
  Failed to inject frame into filter network: Invalid argument
  
  Error while processing the decoded data for stream #0:1
  
  Conversion failed!

  Any help will be highly appreciated.

  PS : I am a beginner in video processing and ffmpeg.

• How to connect ffmpeg to broadcasted rtsp live camera link feeds to users browser ??? These camera link are dynamic so it cannot be defined initially

  9 décembre 2016, par vibhor Gupta

  The following rtsp link gives me feed :
  rtsp ://user:11111@192...***/MPEG-4ch1/main/avstreams

  The following ffmpeg command helps gets me these feed and i can store it on my server :
  ffmpeg -i rtsp ://user:11111@192...***/MPEG-4ch1/main/avstreams -vcodec copy -acodec copy -f mpegts video.mp4

  But when i use the following command broadcast starts but no streaming is received :
  ffmpeg -i rtsp ://user:11111@192...***/MPEG-4ch1/main/avstreams -vcodec copy -acodec copy -f mpegts udp ://127.0.0.1:7000

  I even checked on the server for 7000 port but nothing is running so i am cannot understand what is going.

  To Check I used vlc and in the network stream option i placed udp ://192.168.1.105:7000 as the network url. but it is not working

  So friends i would like to know where i am going and if possible what can be a better solution for this problem ??

  Thank You
