Icecast dev - Aug 2004 - Metadata not updating with oss input module inices2

Hello.

I am running an up-to-date cvs snapshot (10 Aug 03) of ices2, and I
cannot get the Metadata update from file to work (indeed this has always
been true on all previous versions of ices2 that I have used).

If I send the ices process a SIGUSR1, then the error log shows that the
update is taking place, but immediately followed by a read error from
the OSS input module, causing ices to die.

I am running ices on a Solaris 8 for x86 machine with OSS sound driver.

Any ideas on how to get this metadata update to work? I am guessing that
the usr1 signal handler is interrupting the oss input stream somehow.

The error log is shown below:

well it's the first I've heard of it. it has been working for many
people just fine.

not a combination I've used for sure.

This isn't nice, the read returned IO error which is a fatal error, and
thats why ices2 terminated. If this always occurs when a signal is sent
then the driver is broken wrt signal handling. Check to see if there are
any fixes to the driver first.

Do you mean the OSS audio driver itself for Solaris x86? If so - can you
think of how I could check this independently of ices2? For instance -
running some other audio capture app, and sending a signal to another
process?

BTW I have tried upgrading to the latest OSS driver, but still no joy.

Should I pursue this through the OSS support folk instead?
