• How to convert webp images to MP4 video using ffmpeg

  12 octobre 2016, par Sunny Tambi

  I have tried many possible command line options with ffmpeg, however not getting this to work. I want to convert series of webp images to a mp4 video.
  Some commands that i tried are :

  ffmpeg -i img%04d.webp out.mp4
  
  
  
  ffmpeg -i img%04d.webp -c:v libx264 out.mp4
  
  
  
  ffmpeg -i img%04d.webp -pix_fmt yuv420p out.mp4
  
  
  
  ffmpeg -i img%04d.webp -c:v libx264 -pix_fmt yuv420p -crf 25 out.mp4
  
  
  
  ffmpeg -i img%04d.webp -c:v libx264 -pix_fmt yuv420p -crf 25 -b:v 0 out.mp4

  None of them creates an mp4 video. A mp4 file, though, gets created, however it is of 0 sec. Here is a sample output of one of the execution :

  ffmpeg -i img%04d.webp -c:v libx264 -pix_fmt yuv420p -crf 25 -y out.mp4

  Need help if someone can tell how to convert a series of webp images to MP4 video.

• ffmpeg : avi to mp4 (h.264/aac) - sound yes, image no

  21 février 2013, par user1711384

  working with ffmpeg at a conversion (any file to mp4 (h.264/aac)) :

  exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null && \ ", $output1);
  
  var_dump($output1);
  
  exec("ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1", $output2);
  
  var_dump($output2);

  With a mpeg and wmv-file its working. With 2 differenz AVIs it didnt work, logfiles from path 1 arent generated and output1 is empty, output2 of course generates an error. After removing -profile:v baseline in both commands, the videofile is successfull generates, but its not possible to play it in jwplayer (sound yes, but no image).

  This is the content of output1 :

  Do you have a idea, why avi makes problems ? what could be a solution ?

• How to play HDR10 videos using ffplay and ffmpeg ?

  6 janvier 2023, par befandy

  I'm trying to play on Windows a HDR10 video. My display support 10 bits HDR content.
The command that I'm using to play the HDR10 video is the following.
ffplay -sws_flags print_info -i video.mp4

  


  But the output looks washed out.

  


  the log are the following :

  With the help of '-sws_flags print_info' flag we can see that there is a downscaling happening from 10 bits to 8 bits "yuv420p10le -> yuv420p"

  


  I have try to play the video using VLC and it is working fine on my display : colour are vivid and display bright.

  


  I have also try to decode first the video and then past metadata directly to ffplay as follow.
Decoding to yuv format with : ffmpeg -i video.mp4 video.yuv
Then play yuv file : ffplay -framerate 60 -video_size 3840x2160 -pixel_format yuv420p10le -color_range tv -color_trc smpte2084 -color_primaries bt2020 -colorspace bt2020nc -i video.yuv

  


  But the result is the same washed out color and "yuv420p10le -> yuv420p" conversion

  


  Is there a way to play a HDR video (encoded or decoded stream) with ffplay ?
