"Coming and going".
Defined as : "On the same stream, parity can be OK for a few seconds up
to the minute, and then goes wrong, for a similar period. Pausing the
stream can get it right again. Or not."
So, it's not a parity detection problem from the stream, but it may be a
hole in the stack from viafb to softdevice (both included) that make the
whole parity broken.
Since some people (Laz, at least) are positively happy with field parity
on the same setup (versions excluded), that may be :
* either something I missed somewhere in the stack described in my
[update] post (missing patch ?)
* either a bug introduced in the recent CVS versions I grabbed.
Note that dfbinfo and softdevice both report/enable the field parity
capability.
I just tested without libcle266mpegdec (0.4) (setting "-vo dfb:viatv"
instead of "-vo dfb:viatv:cle266" in softdevice's arguments) :
* it mainly works, after the first few seconds playing a stream (during
these few seconds, there are very short glitches)
* there are very few other glitches from time to time (like a few frame
drops)
* without hardware decoding, it may be related to CPU load (Via EPIA
M10k, C3 Nehemiah 1GHz)
