Hello,

I have got a problem on my openPli 9.0 (upgraded to lattest so correction here).
 

Context:
Vu+ solo SE V2 updated to the lattest stable version (update done to day)
Record TNT T2 (1080P)

 

When i play record and fast forward, or back forward a time (for exemple to jump the publicity) when i play back, subtitle does not come again. Nothing appear. On my previous rom OpenATV 5.1, it alwas come back after something like 2s after the ui disapear.
But here, If i jump to an epg marker that delimit the start of new program, it come back again.
If i stop, then play again to come back in the record and enable subtitle, of course it works.

 

Is there something i could do to solve this problem?
Thank's

I cannot confirm it here with subtitles… And when you use step skip instead fast forward and backward?

Does "step skip" is not the case i wrote there: "If i jump to an epg marker that delimit the start of new program, it come back again." with the key > on my remote ?
I did not find other key on my remote to "jump". cross right key does the same then fastforward button.

Ok, i found the jump key, it's 1/3 4/5 7/9.
So if i use this key, it works immediatly, so the problem is just with fast and back forward.

Just don't use them/ only use skip instead , please read https://wiki.openpli...weaks#Skip_time

Yep i found that and already found the key as written before, but that does not explain why it was perfectly working before in an old openAtv and not in openPli 9.0.

If the bug could be corrected it would be better.

 

Just to explain why: the vu+ are used my by parents, so forward/backward is a notion that exist since a lot of time, even if they could understand jump key, you could not say that push on 6/9 key is something intuitive and remember every time how much time jump key does is not something easy for somebody that are more then 70 year old.

And is somebody external come and watch a record, samething, you should explain again where as forward/backward is internatial and have been exist since a lot of time.

You still haven't understood what I have been telling you?

 

You are making assumptions that are not correct: you can not compare the behaviour of driver A with stream X, which driver B and stream Y, and then say "the first combination used to work, so the second must work now", it is simply not true.

 

And I doubt there is a box that has a working fast-forward / fast reverse, given the fact you're not dealing with an analog tape you can speed up or reverse, you're dealing with a compressed MPEG data in a stream with 188 byte packages containing different frame types.

 

You can only reliably jump from I-frame to I-frame, and whether or not you have them, how many, and how they are spaced in the stream, depends on the settings of the MPEG compressor at the source. This is what the jump keys do.

 

Fast forward / Reverse jump to arbitrary locations in the stream, landing on most likely not an I-frame, which means a very complete operation must follow to construct something of an image at that point (apart from I-frames, MPEG frames are delta's on the previous frame, so not a complete picture).

 

Most drivers are not very good at this complex operation, which is made worse if there is corruption in the MPEG stream, which could mean assumptions the drivers make about the stream may not be correct.

 

For your parents, you could update the keymap, and map " <<  " to the 1 key, and " >> " to the 3 key? Downside is that it is only one jump, it doesn't keep jumping until you press play again. I understand that jumping is something new to learn, but it is the technology that is limiting it, not the software.
