Adapter.takeBuffer

Returns a #GstBuffer containing the first @nbytes bytes of the @adapter. The returned bytes will be flushed from the adapter. This function is potentially more performant than gst_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_META_FLAG_POOLED flag or with the "memory" tag.

Caller owns a reference to the returned buffer. gst_buffer_unref() after usage.
