[App] TimeShift Player Seek Patch

[sectroyer]

This is stable version of TimeShift Seek patch for E series. It allows settings time values for both KEY_LEFT/KEY_RIGHT and also adds support for KEY_UP/KEY_DOWN. For me it works all the time and allows setting seek values multiple times without the need to restart TV. Please test it, post your TV model, firmware version and debug (-d) output

Sample usage:

Code: Select all

./timeshiftseekpatch -n exeDSP -d

By default the app sets seek values to +/-30 and +/-90 seconds. Sample useage for different values:

Code: Select all

./timeshiftseekpatch -n exeDSP -d -u 120 -o -120 -l -60 -r 60

The output has to be long because I need to patch it in multiple places. TV uses different classes for different scenarios in TimeShift. For instance CPVRTSMgrNormal is used when you are watching "live" TimeShift. If you rewind it uses CPVRTSMgrPast, etc. That's why it's important to check whether it works in all scenarios

Works here too.

Works here too.

Look for a situation where it doesn't work Let me know if you find one
