  • Loseless FFMPEG compression that supports windows media player

    12 juin 2018, par nmr

    I am trying to create a movie file (avi, mp4, etc as long as it support windows media player) from a sequence of png files using ffmpeg.I am using C++ "System("ffmpeg command")" to create the movie files once I create the png files (this shouldn’t effect movie creation). I was able to create a .avi file using the following command,

    ffmpeg.exe -r 30 -i frame_%7d.png test1.avi

    Once you create the file it runs in windows media player but does not run in VLC. I have realized, it does lossy compression and the movie is not that high quality (quality decreases with frame rate). I want to have lossless compression (or no compression at all) but needs to be able to play in windows media player. So I tried the following commands,

    ffmpeg.exe -framerate 30 -i frame_%7d.png -codec copy test2.avi

    This file ran in VLC but didn’t run in windows media player. Then I tried put in "-pix_fmt yuv420p" but still couldn’t get it to run in windows media player.

    ffmpeg.exe -framerate 30 -pix_fmt yuv420p -i frame_%7d.png -codec copy test2.avi

    I have also tried using "ffv1" codec and it ran in VLC but not in windows media player

    ffmpeg.exe -i frame_%7d.png -c:v ffv1 -qscale:v 0 test4.avi

    So, how do I create a lossless movie file from a sequence of png files using ffmpeg that will run in windows media player ?

  • After ffmpeg conversion to mp3, winamp shows half frequency

    8 octobre 2012, par user404781

    I'm converting movie in flv to mp3 format (just to extract soundtrack) with this options :

    ffmpeg -i movie.flv -acodec libmp3lame -ac 2 -ab 128000 -ar 22050 -vn soundtrack.mp3

    When I check with some free tool I get 44100kHz, but winamp shows half of that - 22050kHz. Which one should I trust ? Maybe ffmpeg options are wrong ?

  • FFmpeg - How to scale a video then apply a watermark ?

    28 août 2016, par Olibanum

    Im trying to scale a video so that it is always 512 wide where the height changes in proportion to the original video.
    Once scaled, I then want to apply a watermark/overlay to the video, therefore the video will scale but the watermark wont.

    I am able to achieve each of these separately using the following filters :

    Scale

    -vf "scale=512:-1"

    Watermark

    -vf "movie=watermark.png [watermark]; [in][watermark] overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2 [out]"

    They work successfully on their own.

    However when trying to combine the two, Im having a bit of trouble.

    Having both as parameters of course does not work as one will override the other.

    Ive tried :

    -vf "scale=512:-1,movie=watermark.png [watermark]; [in][watermark] overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2 [out]"

    my thinking was that the scale would be applied first then the watermark but all I get is an error

    Too many inputs specified for the "movie" filter.

    Error opening filters !

    Then changing the , to a ; resulted in :

    Simple filtergraph ’scale=512 :-1 ;
    movie=watermark.png
    [watermark] ; [in][watermark]
    overlay=(main_w-overlay_w)/2 :(main_h-overlay_h)/2 [out]’ does not have
    exactly one input and output.

    Error opening filters !

    I presume I need to do something more with filterchains but Im struggling to figure it out.

    Any ideas anyone ?

    Many thanks in advance.
