missing:
software deinterlace (yadif, ...)
software decoder with software deinterlace
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
auto crop for va-api
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
