Nothing shameless about the plug! Yes, I have tried softdevice (recent
CVS and recent SVN of ffmpeg). It is actually what I use for viewing
streamed TV (from my main VDR) on my not-so-perfect laptop LCD. The
crop to 4:3 feature works in the way I hoped (4:3 shown as is, 16:9
cropped to show central 4:3 portion).
However, as most things in life, there are some things that do not work
as I would like for main TV viewing:
1. The default deinterlace options, IMHO, do not compare to the tvtime
plugin available using xineliboutput (compare fast-action streams such
as tennis, snooker and football)
2. I cannot watch HDTV content, which I am able to do with the
For sure the deinterlace is of more importance than viewing HDTV (why
would I want to do that on a standard CRT in any case? Proof of concept
and anticipation of a future TV upgrade is the answer).
Both xineliboutput and softdevice, as many users I am sure will testify,
are good pieces of software. However, for my use, both have their
pros and cons.
I usually explore as many configuration options as I can, but please if
there is something I have missed that will allow me to have,
1. Excellent deinterlacing
2. Watchable HDTV/H264
3. 16:9 cropped to 4:3
then please let me know!
In the mean time I am looking at the patch Darren Salt brought to my
attention for xine-lib, and the xine post plugin 'expand' (with special
attention to Reinhard Nissl's center_cut/crop_out mode') to see if I can
hack something for xineliboutput, re cropping 16:9 to 4:3. Noone hold
their breath though.
Thanks to everyone for their help and suggestions. More welcome too.
