  • How can I upscale videos with FFmpeg to a fixed resolution ?

    30 juillet 2020, par Tobias

    Resolution of an example video : 640x788

    


    Desired resolution of the new video : 1920x1080

    


    The aspect ratio of the video should be kept (the area left & right should be filled black).

    


    My current call looks like this : ffmpeg -i input.mp4 -s 1920x1080 -r 60 -aspect 1:1 -strict experimental output.mp4. The problem here is that the video is sometimes made narrower / wider (aspect ratio is not kept).

    


    Since I am no FFmpeg expert I hope for help here (maybe there is a padding property ?)

    


  • How to increase resolution in ffmpeg with rawvideo [closed]

    2 novembre 2020, par Jamie Hutber

    I am using my DSLR with loopback to use as a webcam, however the resolution is locked at 640x426 and I cannot seem to find a way to make this larger as the stream itself is 1080p from the camera.

    


    sudo modprobe v4l2loopback video_nr=2 exclusive_caps=1,1,1 card_label='Screenshare' && gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video2


    


  • FFMPEG reports different (wrong) video resolution compared to how it actually plays

    30 mars 2015, par Emiliano

    Quick question, i have a movie, which was cut and rendered with Sony Vegas from its original format to a .wmv file. Here comes the tricky part, movie when played, either with VLC or WMP, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of 600x480 ....

    I took the time of actually capturing a frame and croping it with photoshop and its 656 and not 600 like ffmpeg its reporting, why would this could be happening ? How could i fix the headers resolution ? Would that have any impact on video re-rendering ? As i said, VLC and WMP seems not to care about the incorrect headers and are playing it right, BUT, jwplayer seems to be using the header information, which i don’t blame him, its correct to do that, but why the video headers could be wrong ?

    ffmpeg -i trailer.wmv
    Input #0, asf, from ’trailer.wmv’ :
Duration : 00:01:04.93, start : 3.000000, bitrate : 2144 kb/s
Stream #0.0 : Audio : wmav2, 44100 Hz, mono, 32 kb/s
Stream #0.1 : Video : wmv3, yuv420p, 600x480 [PAR 59:54 DAR 295:216], 2065 kb/
s, 25.00 tb(r)

    And yeah, the PAR/DAR parameters are also wrong, but honestly, i don’t understand that technical shit, usually watch video and make sure it look good, any feedback would be appreciated :P

    Is there a way to change the container information with ffmpeg so applications that actually do use the container information don’t render video incorrectly ?
