title: The renderer thread don't call SbDecodeTargetGetInfo() while playing 360 video
body: <p>While testing 360 video on our device with cobalt, the application renderer thread will call function SbPlayerGetCurrentFrame() frequently, but there is no SbDecodeTargetGetInfo() and SbDecodeTargetRelease() even we returned SbDecodeTarget object by function SbPlayerGetCurrentFrame(). In howto_decode_to_texture.md, it told that:</p>
  
  <pre><code>Once the application has acquired a valid SbDecodeTarget object through a call to SbPlayerGetCurrentFrame(), it will call SbDecodeTargetGetInfo() on it.
  </code></pre>
  
  <p>Does this mean that we don't return a valid SbDecodeTarget in function SbPlayerGetCurrentFrame(), if so, how does renderer thread check the SbDecodeTarget is valid or not?
      The Cobalt version is 10.56829.</p>
