 <p>Packs <em class="parameter"><code>width</code></em>
  pixels from <em class="parameter"><code>src</code></em>
  to the given planes and strides in the
 format <em class="parameter"><code>info</code></em>
 . The pixels from source have each component interleaved
 and will be packed into the planes in <em class="parameter"><code>data</code></em>
 .</p>
 <p>This function operates on pack_lines lines, meaning that <em class="parameter"><code>src</code></em>
  should
 contain at least pack_lines lines with a stride of <em class="parameter"><code>sstride</code></em>
  and <em class="parameter"><code>y</code></em>

 should be a multiple of pack_lines.</p>
 <p>Subsampled formats will use the horizontally and vertically cosited
 component from the source. Subsampling should be performed before
 packing.</p>
 <p>Because this function does not have a x coordinate, it is not possible to
 pack pixels starting from an unaligned position. For tiled images this
 means that packing should start from a tile coordinate. For subsampled
 formats this means that a complete pixel needs to be packed.</p>

 <p>pixel stride for the given component. This is the amount of bytes to the
 pixel immediately to the right, so basically bytes from one pixel to the
 next. When bits &lt; 8, the stride is expressed in bits.</p>
 <p>Examples: for 24-bit RGB, the pixel stride would be 3 bytes, while it
 would be 4 bytes for RGBx or ARGB, and 8 bytes for ARGB64 or AYUV64.
 For planar formats such as I420 the pixel stride is usually 1. For
 YUY2 it would be 2 bytes.</p>

 <p>All video planes of <em class="parameter"><code>buffer</code></em>
  will be mapped and the pointers will be set in
 <em class="parameter"><code>frame-&gt;data</code></em>
 .</p>
 <p>The purpose of this function is to make it easy for you to get to the video
 pixels in a generic way, without you having to worry too much about details
 such as whether the video data is allocated in one contiguous memory chunk
 or multiple memory chunks (e.g. one for each plane); or if custom strides
 and custom plane offsets are used or not (as signalled by GstVideoMeta on
 each buffer). This function will just fill the <a class="link" href="gst-plugins-base-libs-gstvideo.html#GstVideoFrame" title="struct GstVideoFrame"><span class="type">GstVideoFrame</span></a> structure
 with the right values and if you use the accessor macros everything will
 just work and you can access the data easily. It also maps the underlying
 memory chunks for you.</p>
