  • ffmpeg converting mp4 to gif with color palette results in truncated video

    6 décembre 2019, par Tik0

    I want to generate a gif from my mp4 movie with ffmpeg (ffmpeg version 2.8.15-0ubuntu0.16.04.1) using a color palette. Everything works fine if I do not use a palette :

    $ ffmpeg -i in.mp4 -filter_complex "scale=160:-1" out.gif
    
...
    
frame= 2003 fps=251 q=-0.0 Lsize=   21172kB time=00:01:20.12 bitrate=2164.7kbits/s    
    
video:21155kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.077667%

    But using a palette like so results in Buffer queue overflow, dropping messages and a truncated video

    $ ffmpeg -i in.mp4 -filter_complex "[0:v] scale=160:-1, split [a][b];[a] palettegen [p];[b][p] paletteuse" out.gif

  • Saving highest quality video from video-capture card

    23 décembre 2013, par DusteD

    I have a machine with 2x3 3ghz dual-core xeon and 4x10krpm scsi 320 disks in raid0.
    The capture card is an osprey 560 64 bit pci card.
    Operating system is currently Windows Server 2003.

    The video-stream that I can open with VLC using direct show is rather nice quality.
    However, trying to save this video-stream without loss of quality has proven quite difficult,
    using the h264 codec I am able to achieve a satisfying quality, however, all 4 cores jump to 100% load after a few second and then it start dropping frames, the machine is not powerful enough for realtime encoding. I've not been able to achieve satisfying mpeg1 or 4 quality, no matter which bitrate I set..

    Thing is, the disks in this machine are pretty fast even by todays standard, and they are bored.. I don't care about disk-usage, I want quality.
    I have searched in vain for a way to pump that beautiful videostream that I see in VLC onto the disk for later encoding, I reckon the disks would be fast enough, or maybe something which would apply a light compression, enough that the disks can keep up, but not so much as to loose visible quality.

    I have tried FFMPEG as it seems capable of streaming a yuv4 stream down to the disk, but ofcause FFMPEG is unable to open the dshow device ( same error as this guy Ffmpeg streaming from capturing device Osprey 450e fails )

    Please recommend a capable and (preferably) software which can do this.

  • ffplay -noborder option missing argument

    10 janvier 2021, par Tomás Arturo Herrera Castro

    If I do :

    


    ffplay -i vid.mp4


    


    ffplay works fine, however if I try the borderless option :

    


    ffplay -noborder -i vid.mp4

Failed to set value '-i' for option 'noborder': Option not found


    


    Trying the -noborder option at the end of the command :

    


    ffplay -i vid.mp4 -noborder

Missing argument for option 'noborder'


    


    Any clue on the argument -noborder is waiting for or why isn't this working ?

    


    This is the ffplay version I am using :
