• AWS Lambda and Fluent FFMPEG error "cannot read property "isStream" of undefined"

  29 mai 2021, par Travis Lee

  so here's the goal : convert a .webm file hosted in an S3 into a gif and upload that to a new bucket. This all works fine when run locally, but when trying to translate it into a lambda, fluent-ffmpeg throws errors when it runs the command.

  


  Here's the code snippet :

  


  ffmpeg(new URL(vid))
  .outputOptions("-vf", "scale=320:-1:flags=lanczos,fps=14")
  .on('progress', () => {
      console.log('progress');
  })
  .on('end', () => {
     //Do stuff with the result when it is done
  })
  .output(newKey)
  .run(newKey);


  


  in this snippet, "vid" is a presigned GET url for an S3 bucket containing the .webm video file, and "newKey" is the name of the new bucket (and a temporary writeStream/File that is created in the lambda to store the new .gif file until we upload it to S3 - not super relevant to this issue).

  


  What should happen (and does locally) is that a new output is created containing the converted .gif file

  


  What happens when it is deployed in a lambda is that it reaches the .outputOptions call and throws a type error saying that it cannot read property isStream of undefined.

  


  At first glance, this seems like I simply don't have FFMPEG installed in the lambda, but I do. I have tried with the prebuilt layer using NodeJS 10 found here : https://serverlessrepo.aws.amazon.com/applications/us-east-1/145266761615/ffmpeg-lambda-layer ,
with a NodeJS 12 layer that was built by some engineers here previously, and tried building a NodeJS 14 FFMPEG layer myself and using that. I tried for all three using no configuration and letting it call the PATH ffmpeg, using the FFMPEG_PATH and FFPROBE_PATH environment variables set to either what was specified in the previous layers, or what I made it in the newly built one, and even manually setting the path to the executables using the setFfmpegPath and setFfprobePath functions found on the fluent-ffmpeg object.

  


  Lastly, I even tried bundling the executables in with the actual lambda code itself and uploading it through an S3, trying all three above methods of getting it to point to the correct paths once again to no avail.

  


  I'm seriously in need of help if anyone else has encountered something similar or just might know what is going on. I'm at wit's end here trying to figure this out.

  


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

  cedric - a écrit :

  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 ?
