  • FFmpeg overlaying image onto video fadeout than fadein not functioning

    15 août 2020, par Kursat Turkay

    got a video and png image as an overlay.
    
when I fade in at start of video and fade out at the end, the overlay works as expected.
    
but when I try to reverse the fade effect no error throws but output video does not show any overlay.

    


    ffmpeg -i input.mp4 -i overlay.png -filter_complex
"[1:0]format=rgba,fade=t=in:st=0:d=5:alpha=1,fade=t=out:st=95:d=5:alpha=1[my1]
 [0:0][my1]overlay=W-w-100:H-h-100:shortest=1"


    


    code above works as I expected. but what I want is reverse the effects. the code below not throws any error and produces a video. but no overlay shown at start or end or anywhere.

    


    code below what I guess should work. but not.

    


    ffmpeg -i input.mp4 -i overlay.png -filter_complex
"[1:0]format=rgba,fade=t=out:st=0:d=5:alpha=1,fade=t=in:st=95:d=5:alpha=1[my1]
 [0:0][my1]overlay=W-w-100:H-h-100:shortest=1"


    


    any clues ?

    


  • When creating a Xing or Info tag in an MP3, may I use any MP3 header or does it have to match other frames ?

    13 décembre 2019, par Alexis Wilke

    I have a set of bare MP3 files. Bare as in I removed all tags (no ID3, no Xing, no Info) from those files.

    Just before sending one of these files to the client, I want to add an Info tag. All of my files are CBR so we will use an Info tag (no Xing).

    Right now I get the first 4 bytes of the existing MP3 to get the Version (MPEG-1, Layer III), Bitrate, Frequency, Stereo Mode, etc. and thus determine the size of one frame. I create the tag that way, reusing these 4 bytes for the Info tag and determining the size of the frame.

    For those wondering, these 4 bytes may look like this :

    FF FB 78 04

    To me it felt like you are expected to use the exact same first 4 bytes in the Info tag as found in the other audio frames of the MP3, but when using ffmpeg, they stick an Info tag with a hard coded header (wrong bitrate, wrong frequency, etc.)

    My question is : Is ffmpeg really doing it right ? (LAME doesn’t do that) Could I do the same, skipping the load of the first 4 bytes and still have the greater majority of the players out there play my files as expected ?

    Note : since I read these 4 bytes over the network, it would definitely save a lot of time and some bandwidth to not have to load these 4 bytes on a HEAD request. Resources I could use for the GET requests instead...

  • How to see FFmpeg command MovePY uses ?

    16 novembre 2019, par user319862

    I am trying to figure out why moviepy doesn’t output expected results. How can I log the FFmpeg command that it uses so that I can compare ?
