</div>Because the logo detection code requires a significant number of frames<br>
to accurately identify any logos to use for logo detection.<br>
<br>
If it's really a problem for you, disable logo detection commercial<br>
detection method. Or, feel free to try out the gpu-commflag branch,<br>
which has an unfinished rewrite of commercial detection, which includes<br>
a different logo detection algorithm that tries to identify logos<br>
without having to scan a huge number of frames. But note that that<br>
branch isn't expected to work, so it's probably a bit premature for bug<br>
reports.<br>
