We'd like to request any relevant feedback on this patch. Essentially,<br>we're removing the refresh parameter, since it conflicts with the openGOP<br>parameter.<br>By default, an openGOP will be enabled, which means we could have both<br>
RADL/RASL following CRA pictures. The encoder could control the references,<br>and thus ensure that all leading pictures are decodable (ie that they are<br>always RADL). But IMO, this destroys the purpose of openGOP (?).<br>
Thoughts/opinions welcome.<br>Thanks,<br>Deepthi<br></font></div><br>_______________________________________________<br>
