• 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

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

  1er mars 2020, par theapache64

  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!

  Any help will be highly appreciated.

• Serve media collection to an old iphone 3gs [on hold]

  25 février 2019, par Ale

  I’d like to serve a media collection, hosted in a home network, to an old iphone. I’m pretty much able to do this using apache web server, html, javascript, and jwplayer. But most of the media is in a format that the iphone doesn’t support and so I run into the problem of transcoding each movie I want to play but I would like it to happen on the fly to save time as well as be able to seek or fast forward to different parts of the movie. How can I go about doing this using the tools I already mention ? Php and ffmpeg are also welcome. Other tools are fine but please suggest open source if posible. I’m on a windows pc at this time. I’m sorry for not being too specific. I’m looking for a method or a different set of tools to point me in the right direction.

  Thanks in advance.
