Cannot play multicast stream

[5kinman]

When using the VLC 0.9.8a, the stream plays with only video output.
There is audio track within the stream but the VLC cannot output.

If I update to VLC 1.0.0, the player only show the 1st second.
Here is the message log when playing the stream:

Do anyone know why would this happen and how to fix this?

[VLC_help]

Could you try VLC 1.1.0 nightly builds?

[5kinman]

Thx for the reply.



I have download these 2 versions at the nightly build ftp

1.1.0-rc-20100525-0202-win32

and

1.2.0-git-20100525-0003-win32


Both versions have been tested and they have the same result as the release version 1.0.5:

The video freeze, message box repeating shows these messages

ts warning: lost synchro
ts debug: skipping 104 bytes of garbage
ts warning: discontinuity received 0x8 instead of 0x1 (pid=200)
ts debug: PATCallBack called



The version 0.9.8a can run the same udp multicast stream, but without sounds.

I guest if there is some checking mechanism running after the 0.9.8a version. Is it possible to disable such mechanism, if exists, without re-compiling the binary?

[VLC_help]

If you get

ts debug: skipping 104 bytes of garbage
ts warning: discontinuity received 0xd instead of 0x4 (pid=200)
ts warning: lost synchro
ts debug: skipping 104 bytes of garbage
ts warning: discontinuity received 0x5 instead of 0xe (pid=200)
ts debug: PATCallBack called

with VLC 1.1.0, it would mean, that the stream is against the specs or that there is a bug in VLC.
