mpeg-2 playback crashes when pausing if used together with opengl

[dividuum]

Hi.

I'm not exactly sure what happens, but together with a customer was able to reproduce the problem using stock raspbian (wheezy): Download this mpeg2 file: http://hubblesource.stsci.edu/sources/video/clips/details/images/hst_2.mpg

Then start in two different terminals:

/opt/vc/src/hello_pi/hello_triangle/hello_triangle.bin

and

omxplayer hst_2.mpg

Now pause and unpause the omxplayer video by pressing space a few times. The video will get stuck and won't continue to play. You can terminate both programs but restarting won't work as they hang during initialization. I'm not entirely sure if the combination of playing mpeg2 and opengl is to blame here, but that's how we discovered this problem. Converting the same video to h264/mp4 solves the problem as well, so it's most likely mpeg2 related.

I'm using the following versions:

on a Raspberry PI 2 with a Raspbian wheezy installed.

Can anyone confirm this problem? I tried it all my devices and always run into this. Is there a way to fix this?

[popcornmix]

does omxplayer --nodeinterlace hst_2.mpg still have the problem?

[dividuum]

That does indeed help and it seems to work. With deinterlacing it still stops. Any idea what causes the problem?

Test environment was:

Raspbian Jessie on PI2

Deinterlace uses the 3D hardware. In theory these should co-exist (and in fact must do as Kodi uses opengles for rendering GUI and supports deinterlace) but perhaps there is some conflict.

I'll try to reproduce.

Can you try this test firmware:

Extract the contents to /boot directory (the one you see when sdcard is inserted into widnows).

Seems to work for my test case. I'll test it with a actual setup running at a customer site and reopen if I run into problems. Thanks! Is the change going to make it into the next official release?

[popcornmix]

Yes, the changes should be in next firmware update.
