avisynth AverageLuma() function equivalent in ffmpeg libraries ?
3 novembre 2013, par KG6ZVPI am working on implementing some software to analyze videos and would like to transition the project from avisynth to libavformat/libavcodec.
The Problem : I would like to seek through every frame in a given input video, detect black frames and write that list to a file. Is there a function which would allow me to get the light level of the current frame ? I realize that I may have to implement such a function myself, but as of now, I don't even know where I could collect the information on individual pixels in each frame to start that analysis. Help is greatly appreciated !

ffmpeg concat with different codecs in python
14 avril 2020, par Hans Lutz van Tastiquei'm working on a videopipeline project and try to add some stuff for it.
Atm it's running fine until the code reach this point :



os.system('ffmpeg -i ' + self._rendition + ' -i ' + self._outChunk + ' -filter_complex "[0:0][1:0]concat=n=2:v=1:a=0[outv]" ' + self._tempRenditon)




There is no error message or anything else. It is used to link individual chunks with different codec parameters. After this line it's just telling me that it cant find
self._tempRendition
.


Did i made an mistake with the
os.system
call ?


thx and greetz
