Troubleshooting, known problems, bugs, and workarounds related to this driver:
------------------------------------------------------------------------------
* There's no sound.
Workaround (well, not really a workaround because in the vast majority
of cases this is not a problem with the plugin): check that the version of
ffmpeg's libavcodec that the plugin uses at runtime is the same or /really/
compatible one that you compiled it with. One simple but perhaps a
draconian way to do this is to ensure that you have exactly one version of
ffmpeg/libavcodec installed, remove extra ones if needed, rebuild the
plugin, and try again.
* The MP3 plugin's "show live TV" option while playing stuff doesn't work.
Workaround: none known, but the black screen isn't that bad if you
make the MP3 progress stuff/playlist visible...
* VCD plugin does not work.
Workaround: use the MPlayer plugin to play VCDs.
* No sound with the DVD plugin with VDR >= 1.3.18.
Workaround: use the MPlayer plugin to play DVDs.
Workaround 2: use VDR < 1.3.18.
* When cutting old recordings (made with VDR < 1.3.28 or something, newer
ones should not be affected) from some channels, the still picture is
stuck and won't move when you press 4 or 6 to fine tune the cutmarks.
Workaround: apply Reinhard Nißl's dvbplayer patch for VDR, see
http://home.vr-web.de/~rnissl/vdr-1.3.28-dvbplayer.patch
* If the TV aspect ratio does not automatically adjust according to the
video stream, and you have a ADV7170-based DXR3 and a PAL system, see
em8300-adv7170-wss.patch and vdr-dxr3-wss.patch in the patches/ dir.
* OSD instability, flicker, tearing colors etc can in some cases to some
extent be reduced by using (increasing) the OSD flush rate option in
plugin settings. Many people have reported that the text2skin plugin
with the enElchi skin has worked for them much better than other skins
(even with OSD flush rate set to 0). Some have reported similar success
with the skinelchi skin plugin. Other things to look at include turning
antialiasing off in VDR's setup, and applying
patches/vdr-dxr3subtitlehack.patch to VDR sources, especially if using
DVB subtitles.
* If VDR becomes unresponsive when using the MP3 or Muggle plugins, or
there are stuttering/stickiness problems with the DVD plugin, and
you're using a NPTL system, try disabling NPTL if possible (eg.
export LD_ASSUME_KERNEL=2.4.19 before starting VDR). NPTL cannot be
disabled on all systems, and anyway it would be very nice if someone
found what the problem is, and would submit a patch.
* Wide screen signaling (WSS) requires patching the em8300 driver, and
probably works only with ADV7170, see patches/em8300-adv7170-wss.patch
and http://thread.gmane.org/gmane.linux.vdr/17095
Other (some possibly stale) TODOs:
----------------------------------
* set bcs
* clean unneeded log entries
* stillpicture
* grab screenshot
* add much more comments!
* rewrite some parts of plugin like
- demuxer
- palettemanger
- colormanger
- spuencoder
* osd via
- ffmpeg
- vga overlay
* optimize (is it worth it?)
Rgb2YCrCb
YUV2Rgb
* use xine OSD scaler unconditionally
