Play each frame once at fixed rate in ffmpeg
8 septembre 2023, par Wei HongI have a bunch of videos at various frame rates, some with variable frame rate.


- 

-
First, I wish to play back every frame only once, at 24 fps, no exceptions. I do not want any extra frames or dropped frames. I know that the play length may well change, and audio is unimportant.


-
Next, I wish to do the above after having thrown out all duplicate frames.








Here's what I've been using in a Windows batch file. It almost always works, but for some videos I've caught it dropping a frame :


for %%i in (*.mp4) do ffmpeg -y -i "%%i" -an -c copy -f h264 "%%i.h264"

for %%i in (*.h264) do ffmpeg -y -r 24 -i "%%i" -c copy "%%i.R.mp4"

for %%i in (*.R.mp4) do ffmpeg -y -i "%%i" -b:v 40M -vf mpdecimate,setpts=N/24/TB "MPD%%i.mp4"



What am I doing wrong ?


EDIT : The dropped frames do greatly differ from the previous frames so it's not just mpdecimate at work.

Excluding ARMv5 and ARMv6 devices from Google Play
14 mai 2015, par TarasI build a
ffmpeg
based library for my project and the outputs are really huge. Is it OK to remove the support of old arm processors and leave only arm-v7 and x86 libraries ?I suspect that arm-v7 won’t work on older arm processors.
The application min sdk is 4.0.3 and the question is whether the percentage of devices with old ARM is too small so I can filter them out on Google Play ?
