1) Install kweb 22.214.171.124 as described in the OP of this thread
2) Download and install the partial Buster Upgrade:
Code: Select all
wget http://steinerdatenbank.de/software/kweb_upgrade_buster_20190823.tar.gz tar -xzf kweb_upgrade_buster_20190823.tar.gz cd kweb_upgrade_buster_20190823 ./install
https://www.raspberrypi.org/forums/view ... 0#p1456860 (But you should not download the upgrade from this post, as it is not compatible with Buster).
The Upgrade will also install gksu from Stretch packages, because kweb requires gksudo which is not available in Buster any more.
omxplayer disables all kinds of OSD (subtitles, Position display etc.) on the RPi 4 and on older RPis, if you enable one of the KMS drivers. Of course omxplayerGUI will also be affected by this.
On the RPi 4B, the additional HW codecs (MPEG2 etc.) are not available any more. omplayer(GUI) won't be able to play video files or streams using one of these codecs.
