[Tremor] ov_open fails to open a named pipe

[Bernd Löhr]

Hi,

I'm trying to decode a (Ogg/Vorbis) radio stream with Tremor but always 
get error -132 (...not a Vorbis stream).
When writing the stream as a file everything works fine (also other 
ordinary Ogg files work well).
When writing the stream into a FIFO (with mkfifo) the ov_open (and all 
its relatives) fail. There is only one 1024 Byte block read - and 
that's it.
I also exchanged the callbacks (using read/fread)- no change. It looks, 
as if it cannot sync to a Vorbis header...

The FIFO on our Linux system is 8kB, I tried writing 1, 2 or 4kB 
packets. The FIFO works fine when decoding MP3 streams, so I can rule 
out a fundamental flaw.

I also forced Tremor to read from a file with seekable set to false - 
this also worked up to the end of a song, then Tremor crashed.
Anyway, ov_open succeeded on the same data while it fails if it is a 
FIFO.

Any idea or hint is appreciated.

Thanks
Bernd

PS: I'm new to this list - I looked through the archives and didn't 
find anything similar to this problem, but maybe it turned up later - 
sorry then.
