missing:
    software deinterlace (yadif, ...)
    software decoder with software deinterlace
    auto crop
    zoom/fit-zoom 4:3 (SetVideoDisplayFormat, SetVideoFormat?)
    ITU BT601, ITU BT709 (HD), RGB studio levels (16-235)?
    suspend output / energie saver: stop audio, stop video, configurable
    Option deinterlace off / deinterlace force!
    Make output drivers better modular.

video:
    subtitle not cleared
    subtitle could be asyncron

vdpau:
    VdpPreemptionCallback handling
    hard channel switch
    suspendoutput didn't show logo or black picture.

libva:
    hard channel switch
    yaepghd (VaapiSetOutputPosition) support
    can associate ony displayed part of osd

libva-intel-driver:
    intel still has hangups most with 1080i
    1080i does no v-sync (workaround written)
    OSD has sometimes wrong size (workaround written)

libva-vdpau-driver:
    G210/GT520 OSD update too slow (needs hardware problem workaround)
    hangup on exit (VaapiDelDecoder -> VaapiCleanup
	-> vaDestroyContext -> pthread_rwlock_wrlock)

libva-xvba-driver:

x11:
    disable screensaver

audio:
    write TS -> PES parser, which feeds audio before the next start packet
    CodecAudioOpen can fail "can't open audio codec" and does Fatal exit.
    Combine alsa+oss ringbuffer code.
    Make alsa thread/polled and oss thread/polled output module runtime
    selectable.

audio/alsa:
    better downmix of >2 channels on 2 channel hardware
    remix support of unsupported sample rates
    libav supports only resample of mono to 2 channels
    ffmpeg didn't support resample of 5 to 2 channels

audio/oss:
    alsa oss emulation mixer "pcm" not working
    ring buffer overflow with alsa oss emulation

HDMI/SPDIF Passthrough:
    only AC-3 written
    Channels are wrong setup, if changing setting during operation.
    split pcm and ac-3 out into two devices
    support oss pass-through

playback of recording
    pause is not reset, when replay exit
    replay/pause need 100% cpu

setup:
    Setup of decoder type.
    Setup of output type.
    Setup of display type.
    Setup 4:3 zoom type
    Some setup parameters are not used until restart.
	Can a notice be added to the setup menu?
    576i, 720p, fake 1080i, 1080i

unsorted:
    Menu -> Setup -> Plugins -> skingenigmang -> General
	-> Try 8bpp single area: no, has missing parts.

future features (not planed for 1.0 - 1.5)

    video out with xv
    video out with opengl
    video out with xvba
    software decoder for xv / opengl
    atmolight support
    multistream handling

    upmix stereo to AC-3
