  • FFMpeg mixing audio to video creates silent video after audio is added,

    25 mars 2018, par 1234567

    mixing audio to video creates silent video after audio is added, using FFMpeg

    this is the command I am using

    "-y","-i",j,"-filter_complex","amovie="+audio+":loop=999,asetpts=N/SR/TB,atrim=0:18,adelay=50000|50000,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.5[a1];[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=2.0[a2];[a1][a2]amerge,pan=stereo:c0code>

    I have a video which is 2 mins 7 seconds ling, I want to ’mix’ audio to a part starting from 50 seconds to 68 seconds

    What i want is to keep original sound from video and mix audio to existing sound of video(not over write) it, (keep old video sound and new audio in video)

    what happens is till 50 seconds video has its own sound, from 50 -68 the audio over writes the video sound and from then till end it is silent

    what i want is video to have its sound through out the video and mix from 50 -68 seconds the audio to it

    this graphic can explain a bit of what i want and what i am getting

    What i want enter image description here
    what i am gettingenter image description here
    another problem that I am facing is
    if i try this on a silent video (video with no sound at all) this code fails this is the error that I am getting

  • invalid data found when processing input ffmpeg

    I’m trying to combine some .ts files using ffmpeg. They’re encrypted, but I have the key in the dir with the other files. I used the info from this page to try to combine these files. This is the full code :

playlist.m3u8: Invalid data found when processing input

    It seems someone else on the question I linked to above had the same error that I’m having but nobody responded to it. Any idea what’s wrong ? Thanks

    EDIT : After looking over some more info, the key is also encrypted. This is the key : AI+UjSUn1lhJ/JHbEf5NyVjRBgqScYEKgx18h85zi5E=

    User kape123 managed to get a plain 16 byte key, but there haven’t been updates on the question linked above since September of 2017. The error with the m3u8 file still persists on my end. Thoughts ?
