• Code can not read property 1 of undefined [closed]

  25 mai 2023, par Jesse Copas

  I'm a very new programmer and am working on a Tdarr plugin in JS.
Everything works fine until a 4k file tries to get transcoded and it fails with this log

2023-05-24T19:09:54.907Z ZoBKWMMKG:Node\[hidden-hog\]:Worker\[tall-tuna\]:Error TypeError: Cannot read property '1' of undefined


  


  It's saying that it's unable to read property 1 of undefined and I'm looked and looked and looked and can't find what it is referring to. Hoping to get another set of eyes on it
The plugin Code is here

  Tried transcoding 4k files down to 1080p but it fails due to that undefined error. All Res 1080p and lower that I have tried work correctly

  


  EDIT : I used Console.log and got this back

• What would be the correct way to use Exec or Transcode ffmpeg in SRS version of Windows 5.0.128

  29 janvier 2023, par diegosn79

  i was doing tests in different ways, and i can't use the Exec or Transcode option, i highlight that I have copied the ffmpeg.exe in the objs folder.
These are the codes I tried, and I attach the log errors.

  As seen in this output, the 1st frame appears to be a P frame. I'm curious as to how will the decoder decode this frame without a preceding I frame (key frame) ? The P frame will not have enough information to reconstruct the image from its residual data without the key frame.
