Original commit message from CVS: * configure.ac: Use AC_SYS_LARGEFILE, which will set _FILE_OFFSET_BITS=64 and _LARGEFILE_SOURCE in config.h as required. Do not export those flags in our .pc files any longer (#142209). Remove unused GST_DISABLE_OMEGA_COTHREADS stuff. * gst/elements/gstfilesink.c: (gst_file_sink_class_init), (gst_file_sink_do_seek), (gst_file_sink_event), (gst_file_sink_get_current_offset), (gst_file_sink_render): Redo seek/tell calls with large file support in mind; add some debugging messages; add log message that tells us when large file support is unavailable or not enabled for some reason. * gst/elements/gstfilesrc.c: (gst_file_src_class_init): Add log message that tells us when large file support is unavailable or not enabled for some reason.

* configure.ac:
|

Use AC_SYS_LARGEFILE, which will set _FILE_OFFSET_BITS=64
|
||||
and _LARGEFILE_SOURCE in config.h as required. Do not
|
||||
export those flags in our .pc files any longer (#142209).
|
||||
|

Remove unused GST_DISABLE_OMEGA_COTHREADS stuff.

* gst/elements/gstfilesink.c: (gst_file_sink_class_init),
|
||||
(gst_file_sink_do_seek), (gst_file_sink_event),
|
||||
(gst_file_sink_get_current_offset), (gst_file_sink_render):
|
||||
Redo seek/tell calls with large file support in mind; add some
|
||||
debugging messages; add log message that tells us when large
|
||||
file support is unavailable or not enabled for some reason.
|
||||
|
||||
* gst/elements/gstfilesrc.c: (gst_file_src_class_init):
|
||||
Add log message that tells us when large file support
|
||||
is unavailable or not enabled for some reason.
