Synopsis: QT_MAX_SEEK_SKIPBACK_TIME_CLIENT constant changed to a smaller value to avoid out of memory failure on low memory devices.

Overview: Current 300000 milliseconds value of QT_MAX_SEEK_SKIPBACK_TIME_CLIENT constant needs memory to buffer 300000 milliseconds of video before start rendering it. It causes out of memory failure on low memory devices.  Modified below specified file as given in the diff file to set a smaller value (20000 milliseconds) to QT_MAX_SEEK_SKIPBACK_TIME_CLIENT.
