• ffmpeg Output file #0 does not contain any stream during the extraction of audio from a .webm file

  17 mai 2023, par Leo

  my objective is to extract frames and corresponding audio from a .webm file.

  


  The problem comes when I am extracting the audio from the .webm file.

  


  When I try to extract the audio from the .webm. ffmpeg -i _5rNOD1nsDg.webm -vn -y -ar 44100 -ac 2 output.wav

  


  I get something like below and there is not any .wav file generated.

• Added option to group files in one XHR request based on their file size and the upload file size limit

  15 novembre 2013, par ottens

  Added option to group files in one XHR request based on their file size and the upload file size limit
  If your upload limit is say 1MB and you have 100 files of 20Kb you could set the limitMultiFileUploads to 50 to minimize requests. However is there is one 30kb file the batch containing that group will fail. So I coded an uploadSizeLimitMultiFileUploads option that will calculate the max number of files that fit in one request based on a set upload size. I added a 512 bytes overhead for each file for the calculations to be on the safe side. Hope you find these useful, it is very useful if you want to upload 1000s of small files. Thanks
