why ffmpeg is not working in new installation
3 août 2013, par Hitesh GuptaI 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
r1)Output what I got in command prompt is :

ffmpeg slideshow on raspberry pi raspbian
29 novembre 2017, par mysterious_guyi’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 :

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
