[gst-devel] cdxaparse partial rewrite, using RiffRead

[Stéphane LOEUILLET]

hi ppl,

as foser reported problems on the chan about cdxa not working (mostly
spider not linking it), i tested it with the only cdxa file i had.

it didn't work for me either.

so, i took a look inside and saw that even if CDXA files were RIFF
containers, it didn't use gst-lib/riff/

i saw iain did convert wavparse to use this lib not long ago so i
decided to try to copycat what he did.

in fact, CDXA and WAV have a lot in common : RIFF, fmt & data chunks
(even if fmt format is unknown to me for CDXA files)

you can compare gstwavparse.c to gstcdxaparse.c (after patching) and
you'll know from where it came.

current issues :

when playing from gst-player :
got image and sound but they are not in sync. really don't know why
because it should only be handled by the next element, not cdxaparse
itself.

when playing from gst-launch, using :
gst-launch filesrc location=Karaoke\ FR\ -\ Thierry\ hazard\ -\ Le\
jerk.mpg ! cdxaparse ! spider ! xvimagesink

the full video (which is supposed to last 5min) goes at light speed and
ends in less than 1min

so, perhaps we have to add a time source (like the time stored in CDXA
headers)

i really don't know how to do that (still learning how all this works)

any help, comments appreciated
