Yes, and taapat's isn't using it either, so I guess I'll drop it for now

However I'm still getting the infinite spinner when I stop playing a video (after it runs for a minute or longer).

[gRC] main thread is non-idle! display spinner!

 

I guess it must be the flush in the mediasink or something..

@MastaG

Thank you very much for your effort.

By the way is there any link to your build system ???

I'm interested on your work for STi7162 STB.

Thank you very much

[MastaG]

hyperonex, I'm using taapats build system: https://github.com/T...openpli-oe-core (which uses https://github.com/T...openpli-fulan).

With only a small patch on top of his Enigma2 to bring it in shape for PLi-4 a bit (see attachment).

Also I've edited the stlirc recipe to use a different lirc.conf for the 7162, this one: https://github.com/o...ircd_spark.conf

Furthermore I'm building both libeplayer and gstreamer 1.7 builds now. (simply add/remove libeplayer from MACHINE_FEATURES in meta-fulan/conf/machine/include/oem-fulan.inc).

 

My experience with libeplayer is that it sometimes crashses enigma2 when activating external .srt subtitles.

However with gstreamer 1.7 I'm currently facing a nasty bug where I get an infinite spinner when I stop playing a video file (with or without subtitles).

I'm still looking into this (currently setting up a debug environment).

With gstreamer git head, you need to update opencore-amr to 0.1.3. Otherwise

 

gstreamer1.0-plugins-ugly-amrnb

 

and

 

gstreamer1.0-plugins-ugly-amrwbdec

 

does not build.

 

I don't know if this is related to problem, or you already noticed this...But just in case.

[MastaG]

Thank you Beeker, this really helps me out since I don't have much time to spend on this lately.

I didn't noticed the amrnb plugins not being built anymore myself.

 

Regarding the gstreamer issue, it only happens on spark.

When a h264 video is playing for more than 2 or 3 minutes, I'm getting an infinite spinner once I stop it.

[eServiceMP3] stop /run/movies/A.Bronx.Tale.1993.720p.x264.AC3-Riding High/A.Bronx.Tale.1993.720p.x264.AC3-Riding High.mkv
[gRC] main thread is non-idle! display spinner!

The CPU load goes up to 150% and enigma2 will turn into a zombie when I kill it.

However when I stop playing to movie within a minute or so this won't happen.

 

The exact same build for dm800, dm800se, zgemma h2h and h3 don't have this issue.

 

The only difference between the builds are the receivers' drivers and the mediasink patch.
This patch: https://raw.githubus...k_sh4_fix.patch

Maybe Christophecvr can have a quick look at the patch.

 

Also there's a small difference between the spark's servicemp3.cpp and PLi's servicemp3.cpp:

Anyways I hope to do some gdb debugging tonight.

Any tips or advice is welcome

[mx3L]

@MastaG

I would suggest you to do remote debugging, since then you don't need to install dbg packages, also symbols are loaded on host, so you will certainly not run out of memory.

 

On target:

1. install gdbserver

opkg install gdbserver

2. start gdbserver

gdbserver localhost:2345 /usr/bin/enigma2

On host:

1. setup cross-development environment, toolchain, and sysroot:

MACHINE=machine bitbake image_name -c populate_sdk
cd openpli-oe-core/build/tmp/sdk
./oecore-x86_64-mips32el-toolchain-nodistro.0.sh #select your $SDK directory

2. setup your environment

source $SDK/environment-setup-mips32el-oe-linux

3. enter directory with enigma2 with debugging symbols

cd $SDK/sysroots/mips32el-oe-linux/usr/bin/.debug

4. create .gdbinit file with sysroot set at $SDK/sysroots/mips32el-oe-linux

echo "set sysroot $SDK/sysroots/mips32el-nf-oe-linux/" > .gdbinit

5. start gdb

mipsel-oe-linux-gdb enigma2

6. in gdb connect to target

(gdb) target remote target-host:2345
(gdb) continue

Hope it helps ,

[MastaG]

Thanks a million mx3L.
Your post made my day ! :-)

[lostman]

any expected date for the new image ?

[MastaG]

Soon my friend, I just need to have the spark freeze solved

[oxejatte]

MastaG could you implement VFD-Controls on next release for Spark (Sti 7111) your image is really great on web streams for low ressources boxes.

 

Regards

[MastaG]

mx3L, I've followed the guide but I don't seem to get much useful information.

So I was hoping to see where it actually stalls...

 

Anways when I stop the video within a minute, every is all good, it only happens when I play a video for a longer time.

So here's an example of a video which exits normally:

[MastaG]

Alright so I've loaded up the movie multiple times in gst-launch-1.0's playbin and doesn't lock up there.

So the problem must be within servicemp3.cpp.

Only it's a bit hard to use gdb on enigma2 since it spawns multiple threads and I have to know the function which is stalling when I stop a movie which is playing...

[mx3L]

@MastaG

You have to stop execution once there are spinners by pressing CTRL+C with focused terminal window where you're running gdb.

then use command:

thread apply all bt

It should show you backtrace of all threads

[MastaG]

Thank you mx3L, I was going through all the gdb docs but couldn't find a good example.

So anyways, I think I've found out one of your experimental patches will cause the freeze way more often when stopping a movie.

However it does speed up iptv zapping on all of my other receivers.

I was so caught up in comparing the servicemp3 source code from OpenPLi, OpenATV and Taapat's enigma2 tree that I totally forgot about the patches I was applying myself.

If I don't use the above patch, I can stop my movie and it will go back to the main menu most of the time.

 

Still I got it to freeze once (I had to play and stop my movie many times though).

[gRC] main thread is non-idle! display spinner!

But unfortunately I can't debug it once the spinner comes up since gdb will not go back to the prompt when I press CTRL+C.

I believe this is because enigma2 is using 150% CPU at this time and gdb is unable to halt it.

 

However when I press CTRL+C a second time it will go back to the prompt but I cannot do a backtrace (for the above reason):

(gdb) c
Continuing.
^C
^CQuit
(gdb) thread apply all bt
Cannot execute this command while the target is running.
Use the "interrupt" command to stop the target
and then try again.

 

Now I guess the spark receiver (which is a bit of a slow one) just needs some more time to stop and flush.

I think what happens is that there is a timing problem between the dvbmediasink and enigma2's servicemp3.cpp.

Here's the code in the gstdvbvideosink.c

case GST_EVENT_FLUSH_STOP:
    #ifdef VIDEO_FLUSH
        /* required for spark drivers */
        ioctl(self->fd, VIDEO_FLUSH, 1/*NONBLOCK*/); //Notify the player that no addionional data will be injected
    #endif
    if (self->fd >= 0) ioctl(self->fd, VIDEO_CLEAR_BUFFER);
    GST_OBJECT_LOCK(self);
    self->must_send_header = TRUE;
    while (self->queue)
    {
        queue_pop(&self->queue);
    }
    self->flushing = FALSE;
    GST_OBJECT_UNLOCK(self);
    /* flush while media is playing requires a delay before rendering */
    if (self->using_dts_downmix)
    {
        self->ok_to_write = 0;
        self->playing = FALSE;
    }
    self->flushed = TRUE;
    break;

I guess setting VIDEO_FLUSH to 1 in the spark driver needs a little bit more time.

I'll try and modify servicemp3.cpp to include a little 100 ms sleep and see where it gets me :-)

[lostman]

for me the last image super just need to fix standby and shutdown

i try pkt- openatv- hdmu - eurosat - vix4 - taapat - opendroid and your openpli on my spark sti7111 your image is the best in sharing cccam server and the best in playing iptv but as i say need just to fix the shutdown and standby

[MastaG]

@lostman, the shutdown and standby have been fixed already.

I just need to fix the freezing when stopping a movie before I can release new images.

[christophecvr]

@MastaG

 

Try once to change the spark driver patch:

 

from:

ioctl(self->fd, VIDEO_FLUSH, 1/*NONBLOCK*/); //Notify the player that no addionional data will be injected

to:

if (self->fd >= 0) ioctl(self->fd, VIDEO_FLUSH, 1/*NONBLOCK*/); //Notify the player that no addionional data will be injected

Edited by christophecvr, 5 February 2016 - 12:05.

[MastaG]

christophecvr thank you.

if it solves the problem for good I'll create a nice patch for your sink with a nice "--with-spark" configure option

Will try asap.
