• ffmpeg slideshow on raspberry pi raspbian

  29 novembre 2017, par mysterious_guy

  i’m trying to make slideshow video from few (in this case 3) .jpgs. To do this i’m using

      ffmpeg -r 1/5 -i bat%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p proba12.mp4

  and actually it works on windows (it plays every image for 5seconds) but on raspbian it doesnt work neither on omxplayer nor hello_video.bin (in h264).

  Here is what console shows :

  pi@raspberrypi:~/Downloads $ ffmpeg -r 1/5 -i bat%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p proba12.mp4

  what is also strange if im trying to concatenate those files using text file and i set duration to 5 for every single file it makes different display time... in this example first one displays for 15 seconds, second one for 5seconds and the last one for 10seconds... of course this way of merging images doesnt work under raspbian either

  i’m using raspberry pi 3b with latest raspbian noobs on board

  can you guys please direct me on a solution ? im ran out of ideas... cheers

• why ffmpeg is not working in new installation

  3 août 2013, par Hitesh Gupta

  I was working on live encoding from FFmpeg from last few days. One day I re-installed my OS and tried to run FFmpeg commands again after configuration. My publish points get in starting but could not started. Why ? Am I missing any configuration required ?

  The command I am trying to run is :

  ffmpeg -y -re -i D:\video2.mp4 -pix_fmt yuv420p -movflags isml+frag_keyframe -f ismv -threads 0 -c:v libx264 -preset fast -profile:v baseline -map 0:v -b:v:0 800k http://localhost/PPS/PublishPoint.isml/Streams(Encode

  Output what I got in command prompt is :

• Converting vob to mp4 with ffmpeg

  The following are some information about the input file :

  After the conversion, I open the new file output.mp4 with VLC : but there is a problem with the audio ! If I skip forward the video, the sound disappears or (sometimes) it is distorted. The only way to have the right sound is to disable the audio stream in VLC, and then re-enable it.

  I have found a solution for this problem :

  ffmpeg -i input.vob -c:v libx264 -preset veryfast -crf 19 -c:a aac -b:a 256k -threads 0 output.mp4

  But obviously this isn’t a real solution, because what I obtain is not what I want.
