  <title>Codec Interface</title>

  <note>

    <title>Suspended</title>

  <para>A V4L2 codec can compress, decompress, transform, or otherwise

convert video data from one format into another format, in memory. Typically

such devices are memory-to-memory devices (i.e. devices with the

<constant>V4L2_CAP_VIDEO_M2M</constant> or <constant>V4L2_CAP_VIDEO_M2M_MPLANE</constant>

capability set).

</para>

    <para>This interface has been be suspended from the V4L2 API

implemented in Linux 2.6 until we have more experience with codec

device interfaces.</para>

  </note>

  <para>A memory-to-memory video node acts just like a normal video node, but it

supports both output (sending frames from memory to the codec hardware) and

capture (receiving the processed frames from the codec hardware into memory)

stream I/O. An application will have to setup the stream

I/O for both sides and finally call &VIDIOC-STREAMON; for both capture and output

to start the codec.</para>

  <para>A V4L2 codec can compress, decompress, transform, or otherwise

convert video data from one format into another format, in memory.

Applications send data to be converted to the driver through a

&func-write; call, and receive the converted data through a

&func-read; call. For efficiency a driver may also support streaming

I/O.</para>

  <para>Video compression codecs use the MPEG controls to setup their codec parameters

(note that the MPEG controls actually support many more codecs than just MPEG).

  <para>[to do]</para>

  <para>Memory-to-memory devices can often be used as a shared resource: you can

open the video node multiple times, each application setting up their own codec properties

that are local to the file handle, and each can use it independently from the others.

The driver will arbitrate access to the codec and reprogram it whenever another file

handler gets access. This is different from the usual video node behavior where the video properties

are global to the device (i.e. changing something through one file handle is visible

through another file handle).</para>
