• ffmpeg -pattern_type glob not working in Google Colab

  22 février 2023, par John Jannone

  I'm trying to combine images into video using ffmpeg in a Google Colab Notebook ; I'm getting errors but don't see what I'm doing wrong.

  


  !ffmpeg -pattern_type glob  -i 2023021522* -c:v libx264 video2.mp4

  


  returns : Option pattern_type not found.

  


  !ffmpeg -pattern_type glob  -i '2023021522*' -c:v libx264 video2.mp4 or
!ffmpeg -pattern_type glob  -i "2023021522*" -c:v libx264 video2.mp4

  


  return : 2023021522* : No such file or directory

  


  I also tried adding from glob import glob and just import glob

• Google Cloud Platform Storage JSON API upload breaks audio files..?! How to fix ?

  13 octobre 2017, par Zolai

  I did manage to upload files to Google storage with GCP resumable upload (json api) :
  https://cloud.google.com/storage/docs/json_api/v1/how-tos/resumable-upload

  Using jQuery and Plupload http://www.plupload.com

  But now it seems that audio files loses their codecs in upload and those won’t play or ffmpeg can’t probe those. More testing showed that actually .flac files are ok to ffmpeg, but for example .m4a files are not.

  I need to get most of the audio files uploaded to google storage and be able to probe those with ffmpeg. And must be able upload big files over 100Mb. That’s why I believe JSON API is best or only possible way.

  I think I have metadata also added correctly, but now I’m confused how to continue..
  Any ideas what could be the problem here ?

  EDIT (more info) :

  I had working software :

  • Using regular POST > /temp > Google Cloud Storage Client (php).
  • GCP Storage Client uploaded files with perfection.
  • Even that I named uploaded files with random unique name like "woeiwehf.tmp", those did work and ffmpeg could probe them fine.

  THEN something happened, I guess uploading like this was limited (or something) :

  • What meant that my solution couldn’t upload anymore big files, over 32Mb.

  • Well that wasn’t best solution anyway, so that’s okey, that this changed.

  NOW :

  • I have changed software so it uses GCP JSON API upload resumable, and this mainly works
  • But I had to change files to look like "woeiwehf.flac" or what ever type is. ".tmp" didn’t work anymore.
  • For example .flac files work nicely, but .m4a will not.
  • I’ve tested uploading many different ways, and it seems that JSON API upload loses at least codecs and bit rate.

  I would be very grateful if I could get help how to resolve this.
  I guess one solution may could be to fork ffmpeg client and manually set audio codec, but I’m saving that for the last solution.
