Re: more on avpes2mpeg

[MK <amk@befree.ch>]

Hi,
Here's some more tests: 
I came upon another recorded stream with errors. They seem quite frequent after
all. This one came from gVideo.
avpes2mpeg doesn't choke on it, but afterwards most software decoders do (with a
notable exception of ligos again). again, no sync mux/remux possible.

I tried the pvademux (recently posted to the list) on the original pva.
First it doesn't find a valid header:
   Header plausibility error.
   Video to audio offset: 0 ms.

Must be gVideo that fails to put a header.
Threw away that verification code, tried again, now it's the audio:

  Audio continuity error.
  Previous packet ID: 106
  Current  packet ID: 100
  Video to audio offset: 0 ms.

Hum...
Too many verifications do no good for those less-than-perfect streams. 
avpes to mpeg2 conversion seems not a trivial task. Most tools seem too
"precise" for handling it.

-

The idea of a RTP-ization extension seems definitely a good one.  Especially
if combined with a web extension for VDR control (for example).

-

hardware:
Yesterday I connected the spdif out of the dvb-s to the spdif in of a sblive on
another computer. it does work fine -excepted for ac3 streams, that the
damn sblive doesn't handle at all as input..

Cheers,

MK
