Olivier Crête	d6187c00a6	dmabuf: Make it not a singleton ... Makes it easier to track how many users there are Also make it possible to create a dmabuf struct on systems without mmap, it just won't be possible to map it. https://bugzilla.gnome.org/show_bug.cgi?id=707793	2013-09-18 15:08:53 -04:00
Michael Olbrich	3c66c2a43d	dmabuf: fix mmap counting ... A successful gst_dmabuf_mem_map must always increment the mmap count. Otherwise the first gst_dmabuf_mem_unmap will unmap the memory and all other user will access unmapped memory. https://bugzilla.gnome.org/show_bug.cgi?id=706680	2013-08-26 09:29:32 +02:00
Benjamin Gaignard	84a0934883	allocators: dmabuf: allow testing allocator type ... In decide_allocation function some element may when to test the proposed allocator. For example like this: if (gst_query_get_n_allocation_params (query) > 0) { GstAllocator * allocator; GstAllocationParams params; gst_query_parse_nth_allocation_param (query, 0, &allocator, &params); if (g_strcmp0(allocator->mem_type, GST_ALLOCATOR_DMABUF) == 0) GST_DEBUG("got dmabuf allocator"); else GST_DEBUG("got an other allocator"); } https://bugzilla.gnome.org/show_bug.cgi?id=703659	2013-07-15 15:43:07 +02:00
Benjamin Gaignard	e90e2bb822	dmabuf: Make sure that memory is unmapped before releasing it ... Be sure that memory is unmapped before releasing it. https://bugzilla.gnome.org/show_bug.cgi?id=700411	2013-05-17 09:50:23 +02:00
Michael Olbrich	ced858fa65	dmabuf: set the initial memory size to the full size ... https://bugzilla.gnome.org/show_bug.cgi?id=700427	2013-05-16 11:17:57 +02:00
Michael Olbrich	25dd73521d	dmabuf: don't touch the GstMemory size ... mem.size is the content size and should not be touch. Save the mmap size instead. https://bugzilla.gnome.org/show_bug.cgi?id=699566	2013-05-03 13:13:13 +02:00
Michael Olbrich	a4ba85b151	dmabuf: fix memory initialization ... Without this the shared memory is broken https://bugzilla.gnome.org/show_bug.cgi?id=699565	2013-05-03 13:11:14 +02:00
Michael Olbrich	72e32060b8	dmabuf: fix formating	2013-05-03 13:10:06 +02:00
Michael Olbrich	347898d516	dmabuf: handle mmap failure ... Otherwise gstreamer may segfault trying to access MAP_FAILED. https://bugzilla.gnome.org/show_bug.cgi?id=699470	2013-05-03 11:05:55 +02:00
Sebastian Dröge	c72aefb620	dmabuf: Use the fallback GstMemory copy function instead of our own ... dup() on a dmabuf only gives a new handle, not a copy, thus doesn't do what copy() is supposed to do.	2013-04-25 17:04:50 +02:00
Sebastian Dröge	5d499f1e14	dmabuf: Some code cleanup	2013-03-30 12:08:06 +01:00
Josep Torra	cd1f9ec992	dmabuf: Use correct print format specifier to fix a compiler warning	2013-03-10 18:05:28 +01:00
Sebastian Dröge	354d7ba302	dmabuf: The dmabuf allocator has a custom alloc function, mark it as such	2013-02-22 09:07:40 +01:00
Benjamin Gaignard	9a69f66ed1	dmabuf: Include config.h	2013-02-19 12:41:58 +01:00
Tim-Philipp Müller	1b1bb98256	allocators: add guard and minor clean-ups	2013-02-19 10:45:23 +00:00
Tim-Philipp Müller	4179fe42e0	allocators: add some since markers and misc other doc clean-ups	2013-02-19 09:40:31 +00:00
Tim-Philipp Müller	320c992b94	allocators: header clean-up	2013-02-19 09:35:10 +00:00
Sebastian Dröge	26ff0ced15	allocators: Integrate into the documentation	2013-02-19 10:05:38 +01:00
Sebastian Dröge	37f0067946	allocators: Add single-include header	2013-02-19 10:05:38 +01:00
Sebastian Dröge	76400ef226	dmabuf: Improve documentation and annotations a bit	2013-02-19 10:05:38 +01:00
Benjamin Gaignard	ceecdb8e1d	allocators: Add dmabuf-based GstMemory and GstAllocator ... Create new GstMemory and GstAllocator base on dmabuf. Memory is not allocated/freed by userland but mapped/unmmaped from a dmabuf file descriptor when requested. This allocator is included in a new lib called libgstallocators https://bugzilla.gnome.org/show_bug.cgi?id=693826	2013-02-19 10:05:38 +01:00
