• FFmpeg on Azure Function call running slowly and producing an empty output file

  7 novembre 2017, par The Lemon

  I’m trying to make a function which uses ffmpeg, so far I haven’t been able to get anything other than the -version command to work properly. When I try to run a simple ffmpeg -i {input file path} {output file path} command, the function seems to get stuck for 3-4 minutes (in the process creating an empty output file), then try again and produce the error ’file already exists’. I’ve tried switching between the 64 bit ffmpeg.exe and the 32 bit ffmpeg.exe with the function running as both a 32 and 64 bit function. My code and the associated logs from trying to run the code are included below, if anyone can tell me what I’m doing wrong or how to get the process to work it would be greatly appreciated. Thanks in advance, Cuan

  edit : The process works on kudu with the same files, the output is shown at the bottom. On kudu the process ran in under half a minute, clearly something is causing the function process to hang, if anyone has advice it would be greatly appreciated. Thanks again, Cuan.

  second edit : I tried adding the -y to the end of my command, this works in that it no longer complains about overwriting, but alas it now just hangs twice due to timeout. (output at the bottom)

  edit the third : azure has a way to let you run functions locally, my function ran into the same issues on the local version but : as it turns out the actual processing is done within a few seconds, it just takes forever to decide to write to a file - if you terminate the process manually after the process had been running for 10 seconds the file immediately gets written. Again, any help is appreciated. Cuan.

• Revision e956c00762 : Set and use uv_crop_[width|height] Ensure consistent border extension by roundi

  16 juillet 2014, par Johann

  Changed Paths :
   Modify /vpx_scale/generic/yv12config.c

  
   Modify /vpx_scale/generic/yv12extend.c

  
  
  Set and use uv_crop_width

  Ensure consistent border extension by rounding uv_crop_* at image
  creation time. Where it was rounded problems could arise with the right
  and bottom extensions.
  When padding = 32, y_width = 64, and y_crop_width = 63 :
  (padding + width - crop_width + 1) / 2
  32 + 64 - 63 + 1 should equal 32 *but*
  32 + 1 + 1 equals 34 giving a right buffer of 17 instead of 16.
  By calculating uv_crop_* earlier we round up at the appropriate time and
  for the same values :
  (y_crop_width + 1) / 2
  63 + 1 / 2
  64
  (padding / 2) + uv_width - uv_crop_width
  16 + 16 - 16
  16
