  • Is it possible to split frame accurate an AAC file using FFmpeg ?

    12 mai 2019, par CAHbKA

    What I did :

    # create source material
    
ffmpeg -y -i some.file -c:a libfdk_aac -profile:a aac_he -b:a 128k -ar 44100 source.m4a
    

    
# split into two parts 
    
ffmpeg -y -ss 00:00:00 -i source.m4a -to 6 -c copy part1.m4a
    
ffmpeg -y -ss 00:00:06 -i source.m4a -c copy part2.m4a
    

    
# re-encode only the first part with the same setting as source file
    
fmpeg -y -i part1.m4a -c:a libfdk_aac -profile:a aac_he -b:a 128k -ar 44100 part1reencoded.m4a
    

    
# create file list to be concatenated
    
echo 'ffconcat version 1.0
    
file part1reencoded.m4a
    
file part2.m4a' > my.list
    

    
# finally concatenate both parts
    
ffmpeg -y -f concat -safe 0 -i my.list -c copy parts.m4a
    

    
# play the result
    
ffplay parts.m4a

    Unfortunately, the result file has noises at 00:00:06.

    Is it possible to split frame accurate an AAC file using FFmpeg ?
