• Error using ffmpeg in video downloader : 'ERR : spawn ./db/ffmpeg ENOENT'

  25 septembre 2021, par GingerCoffee

  I've been trying to get Floatplane Downloader to work on my NAS and I've managed to get most of the way. I've set up an Ubuntu Server VM in TrueNAS and got it working in a Docker container. Everything is downloading fine to the right folder on the NAS but once the download finishes I get this error : ERR: spawn ./db/ffmpeg ENOENT

  


  It then tries a couple more times but nothing. I made sure I had ffmpeg installe though I don't know if the reason it can't use it is because it's installed on the host and not in the Docker container directly ? Though I've not been able to work out how to do that or even if it's possible.

  


  I tried just copying ffmpeg from /usr/bin to /var/lib/docker/volumes/db/_data where it seems like it wants it to be and then I get this instead : ERR: Command failed: ./db/ffmpeg -i ./videos/Media/LTT/TechLinked/TechLinked - S2021E0925021600 - STEAM Games on Xbox.partial and then lists all the metadata for the video so I'm not sure that was right.

  


  Whenever I start the downloader, the first thing it says is Ffmpeg binary missing! Downloading...' and then Done a few seconds later. So it seems to be detecting that it doesn't have ffmpeg and then downloads it but that doesn't seem to work.

  


  Any ideas ?

  


• Anomalie #3014 : Chaines de langue de "Forums" utilisées dans la "dist"

  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 ?
