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 (under construction).
video:
subtitle not cleared
subtitle could be asyncron
reduce warnings after channel switch
grab image with scaling support
suspendoutput didn't show logo or black pictures
(must detect video format to show image)
vdpau:
VdpPreemptionCallback handling (under construction)
hard channel switch
libva:
hard channel switch
yaepghd (VaapiSetOutputPosition) support
can associate ony displayed part of osd
auto crop for va-api
grab image for va-api
libva: branch vaapi-ext
add support for vaapi-ext
libva-intel-driver:
intel still has hangups most with 1080i
1080i does no v-sync (workaround written, fixed with vaapi-ext)
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?
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
pip support
grab image with jpeg
upmix stereo to AC-3
