HOW TO APPLY TRANSITION EFFECTS IN FFMPEG ? [closed]
8 janvier 2023, par SMARTI have 7 videos with audio, i tried to apply transition effects on these files, written code in python for this , i got error .


python code :
import subprocess as sp


def runffmpeg(cmd):
 try:
 pipe = sp.Popen(cmd, stdout=sp.PIPE, stderr=sp.STDOUT,
 universal_newlines=True)
 
 ffmpeg_output, _ = pipe.communicate()

 viddur, _ = pipe.communicate()
 
 print(viddur)

 except:
 auddur = 0
 
 print(auddur)
 
 # if (len(auddur) == 0):
 # auddur = 0
 
 return float(viddur.strip()), (auddur)
 
 except sp.CalledProcessError as err:
 print("FFmpeg stdout output on error:\n" + err.output)

these functions creates ffmpeg code like :
ffmpeg -i out1.mp4 -i out2.mp4 -i out3.mp4 -i out4.mp4 -i out5.mp4 -i out6.mp4 -i out7.mp4 -filter_complex " [0:v][1:v]xfade=wipedown:duration=3:offset=6.006009000000001 [x1] ;[1:v][2:v]xfade=dissolve:duration=3:offset=14.030023 [x2] ;[x2][2:v]xfade=pixelize:duration=3:offset=20.572042000000003 [x3] ;[x3][3:v]xfade=vuslice:duration=3:offset=21.621068000000008 [x4] ;[x4][4:v]xfade=radial:duration=3:offset=14.188099000000015 [x5] ;[x5][5:v]xfade=vertopen:duration=3:offset=-5.737862999999978 [x6] ; [0:a]adelay=0|0 [a1] ;[1:a]adelay=9509.509|9509.509 [a2] ;[2:a]adelay=18531.014000000003|18531.014000000003 [a3] ;[3:a]adelay=27552.519000000004|27552.519000000004 [a4] ;[4:a]adelay=36063.026000000005|36063.026000000005 [a5] ;[5:a]adelay=45084.531|45084.531 [a6] ;[6:a]adelay=53595.038|53595.038 [a7] ; [a1][a2][a3][a4][a5][a6][a7]amix=inputs=7 [faud] " -pix_fmt yuv420p -map "[x6]" -map "[faud]" -y trans.mp4


this ffmpeg command generates error :

Building ffmpeg iOS libraries for armv7, armv7s, arm64, i386 and universal
4 février 2015, par sandyI have seen several scripts to build FFmpeg API for armv7, 7s and i386 but couldn’t find anything which would work for armv64 as well. Some of the answers on other threads of this forum suggested to prepare a separate library for arm64 but it does not work well with rest of the architectures. Hence I need a script which can work for all the supported architectures for iOS including armv7, armv7s, armv64 and i386.
