  • Create and combine a blank video stream with a subtitle steam

    10 décembre 2014, par CPO

    I have a live .ts stream that contains a video stream, audio stream and subtitle stream. What I want to do is to display the video in full, eg video and audio and subtitles, but in parallel take the same stream and ’blank’ the video to black, but allow the subtitle stream to be rendered into that video stream for display separately from the fully displayed streams. The reason for this is to allow the subtitles to be displayed separately and cropped,from a second projector, but to have a black backgroung to avoid distractions when there is no subtitle present. I believe this can be achieved using FFMPEG but my limited experience with this utility rather limits my progress. I believe that the blanked video stream needs to be the same frame rate and resolution as the original in order that the rendered subtitles stay in synch with the original video stream. Any help or suggestions warmly welcomed. Thank you

  • merge (video and sound) with (background music)

    27 novembre 2016, par Nir di

    i have video file vid.mpg that contain video and audio(speaking) and audio file aud.wav that contain background music.

    now, i want to merge them together.

    here is the command that i use :

    ffmpeg -i vid.mpg -i aud.mp3 -c:v copy  -filter_complex "[0:a]aformat = fltp:44100:stereo,apad[0a];[1]aformat=fltp:44100:stereo,volume=0.1[1a];[0a][1a]amerge[a]" -map 0:v -map "[a]" -ac 2 -t 0 out.mpg

    and this is the error that i get as response :

    [Parsed_amerge_4 @ 00000000003a36e0] No channel layout for input 1
    
[Parsed_amerge_4 @ 00000000003a36e0] Input channel layouts overlap: output layou
    
t will be determined by the number of distinct input channels
    
[mpeg @ 000000000289a4e0] VBV buffer size not set, using default size of 130KB
    
If you want the mpeg file to be compliant to some specification
    
Like DVD, VCD or others, make sure you set the correct buffer size

    in addition i add the full log :

    C:\bina\ffmpeg\bin>ffmpeg -i vid.mpg -i
    
aud.mp3 -c:v copy  -filter_complex "[1:a]aform
    
at = fltp:44100:stereo,apad[0a];[1]aformat=fltp:44100:stereo,volume=0.1[1a];[0a]
    
[1a]amerge[a]" -map 0:v -map "[a]" -ac 2 -t 0 out.mpg

    How to merge audio with video through FFMpeg C library.

    I have tried muxing.c In this example, audio is created every video frame. But I wanna merge with one full mp3 or wav some other audio format.

    And how to encode the audio file (.mp3) while encoding video from images. I encode image to video using muxing.c.
