• "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

  11 février 2020, par laurent

  I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

  The basic command I have is this one :

  ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  And I’m getting this error :

  [AVHWFramesContext @ 0x32d3f00] Pixel format 'yuvj420p' is not supported
  
  [mjpeg @ 0x2d18480] Error initializing a CUDA frame pool
  
  cuvid hwaccel requested for input stream #0:0, but cannot be initialized.
  
  Error while decoding stream #0:0: Invalid argument

  I’ve tried setting the pixel format like so, but that didn’t help :

  ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?

• FFMPEG Video loop from images files

  27 février 2020, par Nesan Mano

  I am trying to make a video from a bundle of image files and then apply a an overlay on top of it.Another requirement is to make the video loop 3x. It is simply not working.

  The first three paths are pointing toward the same image bundle. (A folder containing images like the following DSC0001_0013.jpg,DSC0002_0013.jpg,etc)

  Observed symptoms :

  The script runs infinitely.I produces a video file of 0 KB.I have to abort script using CTRL+C

  This is my script.

  ffmpeg

• Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

  15 février 2020, par miguelmorin

  I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

  I call this command to concatenate the files :

  ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

  where files_to_combine is :

  file ./short_DSC_0013.MOV
  
  file ./short_DSC_0014.MOV
  
  file ./short_DSC_0015.MOV
  
  file ./short_DSC_0016.MOV
  
  file ./short_DSC_0017.MOV
  
  file ./short_DSC_0018.MOV
  
  file ./short_DSC_0019.MOV

  I call this command from the directory containing the video files and files_to_combine.

  On Windows with a nightly build, I get the error :

  files_to_combine : Invalid data found when processing input
  

  I changed file ./DSC_0013.MOV to these options, all with the same error :

  file 'short_DSC_0013.MOV'
  
  file '.\short_DSC_0013.MOV'
  
  file 'F:\short_DSC_0013.MOV'

  How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

  Update with log-level 48

  I ran the same command with -v 48 and got :

  Update because of wrong command

  I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

  ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4
