[App] Movie Player Seek Patch

[sectroyer]

It looks like this but after this anti-debug fix (and turning off watchdog) everything should work fine... One more think could you post full output of the command that crashes your TV. I want to see what are the values of the registers. And btw how often does the crash happen ?

EDIT:
Just checked the you exeDSP it's "the same" as mine. Patch should work fine for you

The problem is that, as usual, I can't reproduce crash as I wish but let's say an average of 1 crash on 5 tries and 1 on 2 if for example I try to change channel while TV is "held". It seems that TV doesn't like to be asked to do something while it is held
I repeat it, it holds only on first launch of patch after TV start. Never if I patch again.

I've pasted whole command/debug output in my post above:

It this is the output for the "crash scenario" than it is nothing to do with what the patch is doing. And if it works fine latter even if you run it multiple times maybe something is interfering with the patch? Maybe you tried running the patch (manually) to early and it was fighting over exeDSP with some other (probably bugficks') patch that was running (automatically) at the same time ?

As I expected this supposition, I was already trying to disable all other scripts/modules . Sorry no change, even patching alone and looong time after turning on TV.
I always found my TV a bit special, so it may be needed that other ES owners give also feedback.
Anyway, I'm here firstly to test and no matter if that doesn't work on my TV

No patch=no crash . It is always crashing while patch is running/holding though. So, it is related to it.

Yeah that's expectable The only question is why is it holding. If there would be some difference in the output (hold, no hold) than we could work on it

New version uploaded. Please test

[zoelechat]

As expected, perfect!

No more crash/hold, even on first launch...

Here's also a friendly startup script for this patch
-Args/path to be defined on top of script
-USB STOP protection
-stdout/stderr sent to /dtv/logfile and script status)

Maybe it is worth to use not 99... number of exeDSP patch scripts? I used 99 while i was not sure they aren`t stable enough? We`ll save some extra seconds if change number before samba/nfs/apache start... Just a suggestion.

[zoelechat]

You're right, i used 99 when there were "sleep 100" at the top of scripts and before introducing USB STOP protection.
But I don't totally agree for a number before samba/nfs (because it is needed to access files before seeking them )

Let's say... around 90?
