<title>Codec Interface</title> <note> <title>Suspended</title> <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 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>[to do]</para> <!-- Local Variables: mode: sgml sgml-parent-document: "v4l2.sgml" indent-tabs-mode: nil End: -->
