Hey Sébastien, thanks for lending a hand. Here's the situation: I'm using glib binaries from the OpenVista project [1]. I initially used Gstreamer 0.10.13 binaries from <a href="http://freedesktop.org"> freedesktop.org</a> [2], but now I'm building Gstreamer 0.10.13 myself with Visual Studio so that I can debug the problem. I tried to initialize the Gstreamer that I built, but it failed with this error: > Debug Assertion Failed! > File: write.c > Line: 68 > Expression: (_osfile(fh) & FOPEN) The error happens in line 72 of gstregistryxml.c, in the method gst_registry_save. The line is: > written = write (registry->cache_file, str, len); I think the error arises because registry->cache_file has the value 3. registry->cache_file is assigned on line 849 of gstregistryxml.c in the method gst_registry_xml_write_cache. The line is: > registry->cache_file = g_mkstemp (tmp_location); Prior to execution of this line, registry->cache_file is 0. After execution, it is 3. Someone on IRC advised me that this is a problem having to do with the fact that I'm building Gstreamer myself, but not glib. Unfortunately I'm not able to build glib for a number of reasons, so I just got around this problem by inserting > goto fail; before the registry->cache_file assignment. Gstreamer now initializes. Now to the playback problem. Banshee playback is handled in a C library called libbanshee. The relevant file is gst-playback-0.10.c [3]. When a song is played in the interface, the method gst_playback_open is called, and then gst_playback_play (see gst-playback-0.10.c). The error occurs while executing gst_playback_play. I've traced the problem to the method gst_base_src_start in gstbasesrc.c on line 1986: >     result = bclass->start (basesrc); I'm not able to enter that function while debugging (what code is this pointing to?) but when it returns, result is 0. I can provide loads of stack trace info or variable values, but I don't know what would be helpful for you to know. I don't understand what much of the code is doing, but I do know that this is happening during a pad activation (whatever that is). Thanks again for helping out and let me know what other info I can provide.

What's the status of the problems you were having ? This error "GStreamer resource error: OpenRead" makes me think about a LIBC problem as there are some incompatiblities (with files descriptors for ie) between msvcrt.dll and newer versions. What binaries of GStreamer are you using ? Regards, Sebastien Scott Peterson a écrit : > Hey GStreamer folks!
