ffmpeg - DF vs NDF (Drop Frames) vs (Non Drop Frames), how to simply pass input timecode to output
24 septembre 2020, par SelenePlease help with this issue. The broadcaster just rejected my submitted video because their validation tool threw this kind of error :




was configured as "Non drop Frame". "Drop Frame" expected.




I'm only processing video, and I expect the audio to just be copied from input to output.
Running and comparing input with output using ffprobe shows difference in timecode :

Please help !

How to install ffmpeg on Google App Engine ?
1er avril 2024, par london_utkuI intend to install ffmpeg and ffprobe to my Google App Engine flex environment, how can I do this with requirements.txt as a package ?



I am currently using ffmpeg-python yet, this is only a wrapper.



ffmpeg-python==0.2.0
ffprobe-python==1.0.3




Below is the error when I try to use ffmpeg-python wrapper, which is expected as there is no ffmpeg and ffprobe available :

Can you please suggest a way, so I can use ffprobe on Google App Engine.
