Why ffmpeg takes so long time to decode 1 frame from high resolution gif
29 août 2018, par Yueh-Ming ChienI am working on gif to png decode. My command is like :
ffmpeg -probesize 20M -y -i "GIF_High resolution_4952x7000.gif" -y
-frames:v 1 %03d.pngInput : gif (4952x7000)
Output : png
And here’s output result :
It takes about 13 seconds.
If I usepythonto callsubprocess.Popen()to execute it, it causes UI to hang.
And I found something weird inProcess Monitor:
It stuck in process profiling for a long time. I don’t know why. Can anyone help ? I’ll appreciate that.

FFmpeg - Change resolution of the video with aspect ratio
18 septembre 2024, par Arthurall.



How to change resolution of the video with aspect ratio with FFmpeg ?



There are options 
http://manpages.ubuntu.com/manpages/oneiric/man1/ffmpeg.1.html



-s size
 Set frame size. The format is wxh (ffserver default = 160x128,
 ffmpeg default = same as source). The following abbreviations are
 recognized:



and



-aspect aspect
 Set the video display aspect ratio specified by aspect.

 aspect can be a floating point number string, or a string of the
 form num:den, where num and den are the numerator and denominator
 of the aspect ratio. For example "4:3", "16:9", "1.3333", and
 "1.7777" are valid argument values.



For example, I have two input videos :



- 

- with 200*400 resolution
- with 400*700 resolution







I need to make output video with 100*200 resolution.



If I will run ffmpeg with -s 100x200, then second video will have bad aspect ratio.



How can I limit output video by width, with auto aspect ratio by height ?



For example, I want specify for the output video only width 100px and ffmpeg must automatically calculate height with right aspect ratio.



For first video it will be :



200/100=2



400/2=200



Ie 100x200



For second video it will be :



400/100=4



700/4=75



Ie 100x75



Is it possible ?
