gmediarender openwrt

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


hi,

i spent my weekend trying to xcompile gstreamers upnp interface
gmediarender for openwrt.

i have Makefile i am proud of!

well, it compiles but does not run.

while gst-inspect gives me proper output and i can play music with
gst-launch, the libraries apparently don't find any plugin when linked
with gmediarender. at least due to my understanding. the problem may be
somewhere else.

compiling and linking the exact same sources for ubuntu works great.

this is what i get from gmediarender:

it lies! it definetly is not ready for rendering. the status line is
missing too ('GStreamer: play: State change: OLD: 'NULL', NEW: 'READY',
PENDING: 'VOID_PENDING'
').

this is what i get from gst-inspect:

"gmediarender -I 192.168.200.2 --gst-plugin-load=udp,mad
--gstout-audiosink=alsasink" segfaults :-(

"strace gmediarender -I 192.168.200.2 --gst-plugin-load=udp,mad
--gstout-audiosink=alsasink 2>/tmp/strace.log"

shows that, while it seems to properly find the plugins:

open("/usr/lib/gstreamer-0.10/libgstudp.so", O_RDONLY) = 3
open("/usr/lib/libmad.so.0", O_RDONLY)  = 3
open("/usr/lib/gstreamer-0.10/libgstalsa.so", O_RDONLY) = 3

it still segfaults.

this is a tail on strace.log:
---
write(2, "\n(gmediarender:25649): GStreamer"..., 98
(gmediarender:25649): GStreamer-CRITICAL **: gst_object_unref: assertion

) = 98
write(1, "Setting audio sink to alsasink\n", 31) = 31
socketpair(PF_FILE, SOCK_STREAM, 0, [8, 9]) = 0
fcntl64(8, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
fcntl64(9, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---

to make the picture complete, this is the linker command:

for the sake of my next weekend and all those who wait for an openwrt
upn media renderer, please help,
