  • ffmpeg blend to exclude the top videos background

    2 février 2016, par user2995705

    I want to blend two videos, the top video named "top.mp4" was combined with some PNG files,but the combined video’s background was black ? why ?

    then i try to overlay the top.mp4 on another video (named bottom.mp4,was capture by android camera with QUALITY_480P)

    but when I use Overlay filter i find the top.mp4 was not transparent and have a black background on the result.mp4.

    I try to use blend filter to combine top.mp4 and bottom.mp4 to exclude the top.mp4’s black background , but i don’t know how to use the blend filter.

    here is my question :
    1.is it possible to combine PNG files to a video and the video has transparent background ? and then just use overlay filter,the result.mp4 will not have a black mask under the top.mp4 ?

    2.if 1 is impossible, how to blend top.mp4 and bottom.mp4 to exclude the black background of top.mp4

    my all output log

  • audio extracted from flv file via ffmpeg is of shorter duration than the actual flv video [closed]

    11 janvier 2013, par user1961143

    I have extracted audio from flv file via ffmpeg using this command :-

    ffmpeg -i 164_29.flv v19.mp3

    The flv videos duration is 3 minutes but the audio is of 2 mins 20 seconds only. On searching i found that the silent pieces of audio are removed when generating audio from ffmpeg. But i need the audio file to be of exactly same duration as flv video as later i need to put this audio in the flv video itself. Please help as this is urgent for our project. I am running the FFMpeg via .net windows service, so in case you know any other tool which can extract the audio of same duration as video and can be run via .net, it would be useful too.

    If you see the duration of video is of 3:04 but audio extracted from it is of 2:25 only.
    Actually i am using ffmpeg overlay to show two videos side by side in our debate project for the client. Now ffmpeg takes audio from first video by default. But we want the audio from both videos together as a debate going on. Hence I thought of a solution to extract audio from both videos and merge them and than apply them to the overlayed video. This will all work perfectly only if I get the complete audio from the video file i.e. of equal duration.
    For more information i am writing here the overlay command we are using :-

     **ffmpeg -i 164_29.flv  -vf "[in] scale=359:320, pad=2*iw+6:ih
    
  [left];    movie=164_30.flv, scale=359:320 [right]; [left][right] 
    
  overlay=365:0  [out]" -b:v 3600k -y a1.flv**
    

    
 **This is the console output of this overlay command:-**

    C :\Users\ritika.thakur>ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6
    :ih [left] ; movie=164_30.flv, scale=359:320 [right] ; [left][right] overlay=365:0
    [out]" -b:v 3600k -y a1.flv

    Everything is working fine except that we want audio from both videos playing together in final overlayed file. I would be highly grateful if you can help in this and let me know if its possible to do via ffmpeg or not.

  • ffmpeg mp4 to mpeg and back again

    5 décembre 2012, par brux

    I am concatenating mp4 files, from research I have found out you must first encode to mpeg and contatenate those, then convert the larger mpeg file back to mp4.

    For simplicity I am just attempting to convert a.mp4 to mpeg and then back to mp4 (i dont need to worry about the concatenation for now)

    Here is how I first convert to my intermediary mpeg from mp4 :

        ffmpeg -i a.mp4 -q:v 2 -vcodec mpeg2video -acodec copy b.mpg

    The file is encoded with no errors, to convert back to mp4 I do :

        ffmpeg -i b.mpg -vcodec libx264 -acodec copy out.mp4

    Everything seems to work with no errors but out.mp4 just plays the first few frames and then freezes, and the time is skipping randomly as the duration passes for the file. No sound is heard also.
