  • Merge remote-tracking branch ’rdp/dshow_crossbar’

    23 janvier 2015, par Michael Niedermayer
    Merge remote-tracking branch ’rdp/dshow_crossbar’
    

    * rdp/dshow_crossbar :
    dshow : fix docu escapes
    dshow : some devices only list themselves under "Video sources" but actually have both video and audio output pins, so make the audio pins accessible by video source name.
    dshow : add options for allowing filter popup configuration dialogs to be presented to the user
    dshow : introduce support for crossbar [multiple input selectable] devices
    dshow : drop initial audio packets with weird timestamps
    dshow : use non deprecated api
    dshow : miscellaneous tweaks
    dshow : allow selecting devices by an alternative name (workaround for devices with symbols in them), allow specifying capture pins by name and alternative (unique) name
