• h264 extracting frames works only on certain operating system / ffmpeg version

  15 juin 2018, par J. S.

  I have received parsed h264 data from my phone, and I am trying to extract frames from the data.

  I used the following ffmpeg command lines :

  ffmpeg -i temp.h264 -ss 5 -pix_fmt yuv420p -vframes 1 foo.yuv
  
  
  
  ffmpeg -s 1280:720 -pix_fmt yuv420p -i foo.yuv output.jpg

  This results in the right output image on Ubuntu (KDE neon User Edition 5.12) with ffmpeg version 2.8.14.

  However, it does not work on macOS High Sierra (10.13.4) with ffmpeg version 4.0 and instead shows an output message :

  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  I am not sure whether this is a mere ffmpeg version-related issue or not because as an experiment, when I converted the h264 data into mp4 format and played it on macOS High Sierra, the video sometimes shows a sequence of black distorted image (screenshot), and other times, a normal video.

  If I play that same video on Ubuntu (KDE neon User Edition 5.12), the video plays perfectly.

  I don’t understand why this problem would occur, and whether this has to do with OS or ffmpeg library version.
  What would be some good ways to approach this problem ? Thanks.

  I have been working on android-ffmpeg to convert images into videos and I have found the code I was looking(links below) and I have tried to execute this command

  val cmd5 = arrayOf("-analyzeduration", "1M", "-probesize", "1M", "-y", "-framerate", "1/3.79", "-i", Utils.outputPath + "image%d.jpg", "-i", audio!!.path, "-c:v", "libx264", "-tune", "stillimage", "-c:a", "aac", "-strict", "experimental", "-b:a", "192k", "-pix_fmt", "yuv420p", "-shortest", outputLocation.path)

  and I got error saying

  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  can any1 please help me

  I have taken code from here -> KotlinFFmpeg and the code snippet is from here -> MovieMaker.kt, please give me a solution, thanks in advance

  here are the logs

  I have skipped few lines of output as there are many frames. So if you see at the end of output on both A and B sides and look at the number of I, P and B frames,the number of P and B frames on receiver B is more than that at sender A. Can anyone please tell me why there is a change in the number of frames ?
