I have a "simple" solution for this. The user requested a skip, so why sending EOF event in this case? I see no reason for this.
So change filepush.cpp to:143 if (m_stop) 144 break; 141 sendEvent(evtEOF); 145 if (m_stream_mode)
By the looks of it, that would break end-of-file detection (playback should stop when the file ends)
Or only sending EOF if eofcount=10.
that won't fix things on low-bandwidth channels, you'll easily get more than 10 EOF iterations before the buffer has grown to 188*1024 again, so you'd still get the EOF event.

As I looked at the patch I got the impression that the eof detection was damaged by this.

However, to my big surprise, last week i tried an OE2.0 based image and found out that the timeshift works flawless here!
Sorry but this is the end of Openpli for me (unless issue's are fully resolved ).

thanks for looking into it.
I made several tests:
1. Playing recording with skipping before start of file or after file end. And watching until normal end of file -> no problems
2. Normal live tv -> as expected no problems
3. Normal timeshift -> the problem is fixed
My fix "only" sends no EOF, if there was a stop/pause request. So end of file recognition works as before.
If there is a bigger timeshift buffer, then also no EOF event is sent while skipping.
You and everyone else with an ET9x00 can test it. I have attached the enigma2 binary.

but there is a bug runs all the way with pli even pli2
this happen when you start timeshift a channel that included a dvb subs . I mean when resume play TShift the last sub choosed disappear and to get it back need press yellow button and choose it AGAIN.
hope you understand me.

I would like to use your fix but I`m having a VU+Uno.
My build environement is setup and I was able to successfuly build my first OpenPLi image.
Could you please tell me how I can build only the enigma2 binary with the problematic commit reverted?
Many thanks in advance.

@greatred: Here's the howto for my et9200. Your directories might be named in a different way.
1. Go to your build directory: <path_to_build_dir>/openpli-oe-core
2. Edit site.conf and put a # before last line:
#INHERIT += "rm_work"3. Change to <path_to_build_dir>/openpli-oe-core/build-et9x00 directory
4. Execute this
source env.source; bitbake -f -c compile -b ../meta-openpli/recipes-openpli/enigma2/enigma2.bb5. Enigma2 unpatched binary is now located in this directory:
<path_to_build_dir>/openpli-oe-core/build-et9x00/tmp/work/et9x00-oe-linux/enigma2-2.7+......./git/main
6. Edit this file: <path_to_build_dir>/openpli-oe-core/build-et9x00/tmp/work/et9x00-oe-linux/enigma2-2.7+......./git/lib/base/filepush.cpp
Goto line 141 and change
sendEvent(evtEOF); if (m_stop) break;into this
if (m_stop) break; sendEvent(evtEOF);And save file.
7. Change to <path_to_build_dir>/openpli-oe-core/build-et9x00 directory
8. Execute this
source env.source; bitbake -f -c compile -b ../meta-openpli/recipes-openpli/enigma2/enigma2.bb9. If there were no error messages, binary is located here: <path_to_build_dir>/openpli-oe-core/build-et9x00/tmp/work/et9x00-oe-linux/enigma2-2.7+......./git/main
Please check file date of the binary. It must have the date of the second compile!!
10. You can strip binary to make it smaller (I should be around 40MB. After stripping it's only 2,8MB big). You don't need to do this:
To strip execute this:
<path_to_build_dir>/openpli-oe-core/build-et9x00/tmp/sysroots/i686-linux/usr/bin/mips32el-oe-linux/mipsel-oe-linux-strip<space><path_to_enigma2_binary>11. Put the binary on your stb. E.g. in /tmp and do a chmod 755 enigma2
12. Do a init 4
13. Start enigma2 from /tmp with ./enigma2

seems that thanks to this @pieterg's commit:
http://openpli.git.s...5dab92ecab10ef7
vu last timeshit issues (an incorrect timeshif behavior on un-pausing /ie jump to 'live'/) should be fixed from the next build

assuming you have openpli oe core build enviroment set up:
1. clone (openpli) enigma2 repository
2. make your changes in there
3. bitbake enigma2 pointing to the recipe included in your local e2 repo, something like this:
brt@brt:~$ cd openpli-oe-core/build-vuduo/ brt@brt:~/openpli-oe-core/build-vuduo$ source env.source brt@brt:~/openpli-oe-core/build-vuduo$ bitbake -b ~/enigma2/enigma2.bbit will fail on do_package, but you'll find package content in ~/enigma2/build/package
(and of course on subsequent tests/builds you'll have to remember all these pull / reset / cleansstate etc...)
//and sorry for OT

I don't believe(but cannot exclude) that it fixes the problem with seeking back when you are almost at the end of the timeshift buffer (as described in this thread).
For this you should change the filepush.cpp
It would be great if you can test it.
@blzr: Thanks! That seems easier. My current problem was that everytime someone commited a patch a new folder was checked out and I had to move my changes to the new folder.

@dima: black screen while seeking? I don't have that. I only had black screens when I started normal time shift. What Stb do you use? What do we have to do to reproduce your problem?

Re: Timeshifting problems with OpenPLi 3.0 #180
Posted 3 February 2013 - 15:27
I made several tests:
1. Playing recording with skipping before start of file or after file end. And watching until normal end of file -> no problems
2. Normal live tv -> as expected no problems
3. Normal timeshift -> the problem is fixed
My fix "only" sends no EOF, if there was a stop/pause request. So end of file recognition works as before.
If there is a bigger timeshift buffer, then also no EOF event is sent while skipping.
I've taken a closer look at the evtEOF handling in filepush, and indeed when we avoid emitting evtEOF when the thread is stopping (thus ignoring the decoder being empty, which it is because of the skip attempt), avoids that the timeshift switches to the live point.
And as far as I can see there are no side effects.
Only one thing is remaining, as Dima73 points out, sometimes you cannot rewind from the live point, you'll get a black screen.
In that case, the only way to get away from the live point, is press pause, and wait a few seconds.
