$Id: $
missing:
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 moduluar.
vdpau:
1080i with temporal spatial and level 1 scaling too slow with my GT 520
1080i with temporal spatial too slow with my GT 520 on some channels
SkipChromaDeinterlace improves performance
Improve OSD handling, show only what is used. Big OSD costs performance
VdpPreemptionCallback handling
hard channel switch
suspendoutput didn't show logo or black picture.
libva:
hard channel switch
yaepghd (VaapiSetOutputPosition) support
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 osd update too slow (needs hardware problem workaround)
OSD update is too slow
hangup on exit (VaapiDelDecoder -> VaapiCleanup
-> vaDestroyContext -> pthread_rwlock_wrlock)
libva-xvba-driver:
x11:
disable screensaver
audio/alsa:
done? video/audio asyncron
random crashes in av_parser_parse2, when switching channels
sometimes alsa hangs
fixed? snd_pcm_state: Assertion `pcm' failed. while switching channels
(thread problem)
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
CodecAudioOpen can fail "can't open audio codec" and does Fatal exit.
audio:
write TS -> PES parser, which feeds audio before the next start packet
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
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
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
