  • ffmpeg concat takes too much time

    7 juillet 2021, par DavidB

    Trying to concatenate large mp4 files. Before 48000 if it takes about 500ms to be done, then after 48000 time increases dramatically to 10000ms. What I am missing ?

    


    ffmpeg -f concat -safe 0 -i cn.txt -c copy concated.mp4

$cn_txt = 
"ffconcat version 1.0
file t.mp4
outpoint 48000
file ad.mp4";
  // outputs in 500ms

$cn_txt = 
"ffconcat version 1.0
file t.mp4
outpoint 49000
file ad.mp4";
  // outputs in 10000ms


    


  • Ffmpeg issue : At the time of convert from .webm to .mp4 it getting 0 MB size

    27 janvier 2019, par amit kumar

    At any time I get video file whereas video as .webm. So, files have different different size.

    Now the issue is : I have a pair of video files whose video size is 7 mb when they execute to create mp4, then it success whose mp4 size become 5.18 MB.

    At the same time again I have a files whose size is 4.65 MB of video as .webm then, when they execute then Mp4 files are create but size becomes 0 MB.

    So I need help why this becomes 0 MB.

    Note : whereas I am using this command :

     (-i  407118_agentPL27_2018-09-26T16-18-17.webm  407118_agentPL27_2018-     
    
  09- 26T16-18-17_in.mp4)

    I have many of files whose size lies between 1 MB to 1 GB, they also not create MP4. But, in between if give 7 MB to 9 MB file it creates with Proper size.

    I need the command as above which I send, from that command if I pass into ffmpeg between 1 MB to 1GB .webm file then the MP4 file should must be created.

    Note : I don’t have console output because I am implementing this command with C#.
