Struct gstreamer_base::Adapter [−]
pub struct Adapter(_, _);
This class is for elements that receive buffers in an undesired size. While for example raw video contains one image per buffer, the same is not true for a lot of other formats, especially those that come directly from a file. So if you have undefined buffer sizes and require a specific size, this object is for you.
An adapter is created with Adapter::new
. It can be freed again with
gobject::ObjectExt::unref
.
The theory of operation is like this: All buffers received are put
into the adapter using Adapter::push
and the data is then read back
in chunks of the desired size using Adapter::map
/Adapter::unmap
and/or Adapter::copy
. After the data has been processed, it is freed
using Adapter::unmap
.
Other methods such as Adapter::take
and Adapter::take_buffer
combine Adapter::map
and Adapter::unmap
in one method and are
potentially more convenient for some use cases.
For example, a sink pad's chain function that needs to pass data to a library in 512-byte chunks could be implemented like this:
static GstFlowReturn
sink_pad_chain (GstPad *pad, GstObject *parent, GstBuffer *buffer)
{
MyElement *this;
GstAdapter *adapter;
GstFlowReturn ret = GST_FLOW_OK;
this = MY_ELEMENT (parent);
adapter = this->adapter;
// put buffer into adapter
gst_adapter_push (adapter, buffer);
// while we can read out 512 bytes, process them
while (gst_adapter_available (adapter) >= 512 && ret == GST_FLOW_OK) {
const guint8 *data = gst_adapter_map (adapter, 512);
// use flowreturn as an error value
ret = my_library_foo (data);
gst_adapter_unmap (adapter);
gst_adapter_flush (adapter, 512);
}
return ret;
}
For another example, a simple element inside GStreamer that uses Adapter
is the libvisual element.
An element using Adapter
in its sink pad chain function should ensure that
when the FLUSH_STOP event is received, that any queued data is cleared using
Adapter::clear
. Data should also be cleared or processed on EOS and
when changing state from gst::State::Paused
to gst::State::Ready
.
Also check the GST_BUFFER_FLAG_DISCONT flag on the buffer. Some elements might need to clear the adapter after a discontinuity.
The adapter will keep track of the timestamps of the buffers
that were pushed. The last seen timestamp before the current position
can be queried with Adapter::prev_pts
. This function can
optionally return the number of bytes between the start of the buffer that
carried the timestamp and the current adapter position. The distance is
useful when dealing with, for example, raw audio samples because it allows
you to calculate the timestamp of the current adapter position by using the
last seen timestamp and the amount of bytes since. Additionally, the
Adapter::prev_pts_at_offset
can be used to determine the last
seen timestamp at a particular offset in the adapter.
The adapter will also keep track of the offset of the buffers
(GST_BUFFER_OFFSET
) that were pushed. The last seen offset before the
current position can be queried with Adapter::prev_offset
. This function
can optionally return the number of bytes between the start of the buffer
that carried the offset and the current adapter position.
Additionally the adapter also keeps track of the PTS, DTS and buffer offset
at the last discontinuity, which can be retrieved with
Adapter::pts_at_discont
, Adapter::dts_at_discont
and
Adapter::offset_at_discont
. The number of bytes that were consumed
since then can be queried with Adapter::distance_from_discont
.
A last thing to note is that while Adapter
is pretty optimized,
merging buffers still might be an operation that requires a malloc
and
memcpy
operation, and these operations are not the fastest. Because of
this, some functions like Adapter::available_fast
are provided to help
speed up such cases should you want to. To avoid repeated memory allocations,
Adapter::copy
can be used to copy data into a (statically allocated)
user provided buffer.
Adapter
is not MT safe. All operations on an adapter must be serialized by
the caller. This is not normally a problem, however, as the normal use case
of Adapter
is inside one pad's chain function, in which case access is
serialized via the pad's STREAM_LOCK.
Note that Adapter::push
takes ownership of the buffer passed. Use
gst_buffer_ref
before pushing it into the adapter if you still want to
access the buffer later. The adapter will never modify the data in the
buffer pushed in it.

pub fn take_buffer(&self, nbytes: usize) -> Option<Buffer>
[src]
pub fn take_buffer(&self, nbytes: usize) -> Option<Buffer>
Returns a gst::Buffer
containing the first nbytes
bytes of the
self
. The returned bytes will be flushed from the adapter.
This function is potentially more performant than
Adapter::take
since it can reuse the memory in pushed buffers
by subbuffering or merging. This function will always return a
buffer with a single memory region.
Note that no assumptions should be made as to whether certain buffer flags such as the DISCONT flag are set on the returned buffer, or not. The caller needs to explicitly set or unset flags that should be set or unset.
Since 1.6 this will also copy over all GstMeta of the input buffers except
for meta with the gst::MetaFlags::Pooled
flag or with the "memory" tag.
Caller owns a reference to the returned buffer. gst_buffer_unref
after
usage.
Free-function: gst_buffer_unref
nbytes
the number of bytes to take
Returns
a gst::Buffer
containing the first
nbytes
of the adapter, or None
if nbytes
bytes are not available.
gst_buffer_unref
when no longer needed.
pub fn take_buffer_fast(&self, nbytes: usize) -> Option<Buffer>
[src]
pub fn take_buffer_fast(&self, nbytes: usize) -> Option<Buffer>
Returns a gst::Buffer
containing the first nbytes
of the self
.
The returned bytes will be flushed from the adapter. This function
is potentially more performant than Adapter::take_buffer
since
it can reuse the memory in pushed buffers by subbuffering or
merging. Unlike Adapter::take_buffer
, the returned buffer may
be composed of multiple non-contiguous gst::Memory
objects, no
copies are made.
Note that no assumptions should be made as to whether certain buffer flags such as the DISCONT flag are set on the returned buffer, or not. The caller needs to explicitly set or unset flags that should be set or unset.
This will also copy over all GstMeta of the input buffers except
for meta with the gst::MetaFlags::Pooled
flag or with the "memory" tag.
This function can return buffer up to the return value of
Adapter::available
without making copies if possible.
Caller owns a reference to the returned buffer. gst_buffer_unref
after
usage.
Free-function: gst_buffer_unref
nbytes
the number of bytes to take
Returns
a gst::Buffer
containing the first
nbytes
of the adapter, or None
if nbytes
bytes are not available.
gst_buffer_unref
when no longer needed.
pub fn take_buffer_list(&self, nbytes: usize) -> Option<BufferList>
[src]
pub fn take_buffer_list(&self, nbytes: usize) -> Option<BufferList>
Returns a gst::BufferList
of buffers containing the first nbytes
bytes of
the self
. The returned bytes will be flushed from the adapter.
When the caller can deal with individual buffers, this function is more
performant because no memory should be copied.
Caller owns the returned list. Call gst_buffer_list_unref
to free
the list after usage.
nbytes
the number of bytes to take
Returns
a gst::BufferList
of buffers containing
the first nbytes
of the adapter, or None
if nbytes
bytes are not
available

[src]
pub fn take_list(&self, nbytes: usize) -> Vec<Buffer>
Returns a glib::List
of buffers containing the first nbytes
bytes of the
self
. The returned bytes will be flushed from the adapter.
When the caller can deal with individual buffers, this function is more
performant because no memory should be copied.
Caller owns returned list and contained buffers. gst_buffer_unref
each
buffer in the list before freeing the list after usage.
nbytes
the number of bytes to take
Returns
a glib::List
of
buffers containing the first nbytes
of the adapter, or None
if nbytes
bytes are not available
