    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.

    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • 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 :

  • 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.
