Crash after playing a paused video #27

Closed lukas-hetzenecker closed 9 years ago

lukas-hetzenecker commented 9 years ago

I'm using POT 4.5.1 for Raspberry Pi 2 and whenever I try to play a paused video the application crashes with the following error: /home/luca/project/pi/pi/piomxtextures_src/omxplayer_lib/OMXVideo.cpp:81: OMX_ERRORTYPE fill_buffer_done_callback(OMX_HANDLETYPE, OMX_PTR, OMX_BUFFERHEADERTYPE*): Assertionprovider->registerFilledBuffer(pBuffer)' failed.`

The full output is provided here:

The steps for reproducing this bug are as following:

  1. Create a VideoOutput and load a video
  2. Start the playback (video.play())
  3. Pause it (video.pause())
  4. Start it again -> this results in a crash

Can this bug be reproduced by someone else?

Did you also try with POCPlayer? Click on the surface to get the controls and try to pause/play the video. Do you get a crash?

lukas-hetzenecker commented 9 years ago

yes, exactly the same crash happens with the pocplayer

carlonluca commented 9 years ago

Could you please have a look at this version of the library: http://we.tl/a7j9fvdufK. This is the version for Pi1, so use this with the Pi1 package.

@carlonluca I made test with several versions:

So I guess the problem is related to the improvements you made at the latest RPi2 version, and maybe something missing in our compiling environment or target.

lukas-hetzenecker commented 9 years ago

Thanks for testing @Nightmare204 - i unfortunately hadn't time to test the provided binaries yet

carlonluca commented 9 years ago

Yes, only the optimised version should be bugged.

Version 5.0.0-beta1 should fix this. Reopen if needed.
