Bug ID: 751241
Summary: vtdec: handle non-consecutive GstBuffer input without
copying
Classification: Platform
Product: GStreamer
Version: git master
OS: Mac OS
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-bad
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: ilya.konstantinov at gmail.com
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
CMBlockBuffer offers a model similar to GstBuffer, whereas it can consist of
multiple non-consecutive memory blocks.
Instead of using gst_buffer_map, we should:
- iterate over the GstBuffer's memories
- map the GstMemory objects individually
- create a CMBlockBufferCustomBlockSource {
.AllocateBlock = nil,
.FreeBlock = { wrapper function that does gst_memory_unmap + unref },
.refCon = gst_mem
} for each memory
- call CMBlockBufferAppendMemoryBlock, passing the mapped pointer and the
custom block source
This complements bug 751071. Possibly, this function should be moved out into
the applemedia library.
