• linux ffmpeg Live streaming cannot connect to another PC

  9 juin 2019, par Tae-Yeong

  I’m set ffserver and ffmpeg streaming code in the linux console terminal.

  ffserver => ffserver -f ./ffserver.conf (terminal 1)

  ffmpeg => ffmpeg -r 15 -s 640x480 -f video4linux2 -i /dev/video0 http://mylocalhostip:8090/feed1.ffm (terminal 2)

  It was working success in the localhost.
  But It could not connect other PC or Mobile.
  Firewall set disable.

  My desktop and mobile have a normal Internet connection.

  I want to Live-Streaming connect other PC or Mobile.
  How can I do ?

  Hardware = LattePanda
  OS = Ubuntu 16.04

  < ffserver.conf >

  HTTPPort 8090

  bind to all IPs aliased or not

  HTTPBindAddress 0.0.0.0

  max number of simultaneous clients

  MaxClients 1000

  max bandwidth per-client (kb/s)

  MaxBandwidth 10000

  Suppress that if you want to launch ffserver as a daemon.

  NoDaemon

• FFserver : cannot connect via rtsp

  27 avril 2016, par newfoundstory

  so im currrently trying to stream my windows desktop using ffmpeg into a raspberry pi running ffserver.
  The client software im using needs to use RTSP, however i cannot connect to the stream no matter what i try.

  Any help would be greatly appreciated !
  Im attempting to access the stream with rtsp :// 169.254.70.227 :8544/test.flv, as soon as i do it stops the ffmpeg feed

• Artifacts in screen captures from h.264 video using python-ffvideo

  8 juin 2015, par ajt

  I am using a python module called python-ffvieo to capture video stills from mkv files that are h.264 encoded. When I perform my screen captures the image files are heavily pixelated and contain many artifacts.

  I have converted one of the mkv files to a flv file and am able to get screen captures from it with no artifacts or pixilation. I am wondering if this is a codec issue or something similar, but I am not sure how even to go about troubleshooting it.

  Here is the information from ffmpeg on the mkv file that I am trying to get the image captures from :

  Input #0, matroska,webm, from 'mm.mkv':
  
    Metadata:
  
      encoder         : libebml v1.3.0 + libmatroska v1.4.1
  
      creation_time   : 2014-10-13 23:55:52
  
    Duration: 00:48:03.71, start: 0.000000, bitrate: 1370 kb/s
  
      Stream #0:0: Video: h264 (High), yuv420p(tv), 1280x720 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
  
      Stream #0:1: Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s (default)

  And here is an image sample of the pixelation that I am talking about :

  

  I know that this isn’t much to go off of and that the python module that I am using is kind of old, but I could really use some help.
  Are these types of artifacts common when there is an encoding issue ? Can anyone tell me what I should be looking into to troubleshoot this ? I appreciate any and all help.
