• choosing outbound IP (eth0 or eth1) in FFMPEG

  4 septembre 2018, par Ba Ta

  I have 2 IP addresses on my server.

  $curl --interface eth0 ifconfig.co      
  
  111.111.111.111
  
  
  
   $curl --interface eth0:0 ifconfig.co      
  
  222.222.222.222

  So via curl I can switch via interfaces so my IP address changes when I visit any url based on eth IP

  How can I use same thing via ffmpeg ?

  For example, if want to access this video via ffmpeg (it uses 111.111.111.111 to access it)

   ffmpeg -i 123.com/video.mp4

  how can I access same video from my second IP 222.222.222.222 ?

  Is there any command like this, perhaps ?

  ffmpeg --interface eth0:0  -i 123.com/video.mp4

  ah ben c’est peut-être ça la solution : on duplique rien mais on mais une chaine neuve dans le core, plus générique (qui ne mentionne pas explicitement le champ, et permet de passer un nombre de caractères) :

  'attention_champ_mini_nb_caractères' => 'Attention ! @nb@ caractères au minimum'

  Claro, car pour l’instant on fait un peu "morte quoi" comme dirait quelqu’un, cf `forum_attention_dix_caracteres` VS `forum_attention_nb_caracteres_mini` ici https://git.spip.net/spip/forum/src/branch/master/lang/forum_fr.php#L42 ; donc une chaîne neutre (ou générique ^^) permettrait de faire du ménage.

  (au passage b_b si on créé une nouvelle chaine que trad.spip.net connait déjà, il recopie toutes les trads qu’il connait à l’import)

  ha usper, thx pour l’info :)

• Automatic encoder selection failed for output stream #0:1

  9 juin 2018, par Rafael Lima

  I’m trying to use ffmpeg for edit some videos on android...
  It is working fine but if I try to use drawtext i get error

  the command is :

  path/ffmpeg -y -i /path/asd.mp4 -map 0 -segment_time 15 -f segment -c:v libx264 -preset veryfast -crf 30 -vf "drawtext=text='test message ':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h" -r 30 -force_key_frames expr:gte(t,n_forced*15) -an /path/temp%03d.mp4

  and the error is :

   Error selecting an encoder for stream 0:1

  things to considere :
  1. I’ve checked 3 times all the paths are valid
  2. I’ve tested the same command on ffmpeg 4.0 on windows and it works [with the same video]
  3. If I remove the drawtext filter it works fine...

  I tought it ffmpeg was built without drawtext or with some error so i spent 10 days in order to build it bymyself and guarantee every dependency is ok... but at end i got the same error

  does anyone have any idea please

  ==============================
  UPDATE

  I keep testing and if I remove the quotes from the filter and use a text without spacing it works

  ex :
  drawtext=text='test_message':fontfile=/path/arial.ttf:box=1:boxborderw=30:boxcolor=0xE86F67@0.7:fix_bounds=true:fontcolor=0x2A363B:fontsize=32:x=0:y=h

  so I believe there is something related to how android is escapes quotes and simple quotes because i compiled ffmpeg with same parameters and it runs on ubuntu with spaces at the text (just need to use simple quotes)

  does anyone know about it ?
