Android surface corruption

[Damien Dejean]

Hi gstreamer team !

We’re currently using GStreamer 1.4.5 on Android to read a RTP/VP8 stream from the network, decode it and display it on an Android native surface using the glimagesink. We’re facing a strange interaction between GStreamer and the surface we delegated to it. The typical use case for us is to set up the pipeline, and when the pipeline is READY we’re injecting him the surface. When the network stream comes, the pipeline move from PAUSED to PLAYING and it plays correctly. Then we stop playing, remove the surface and we destroy the pipeline.

But if after the injection, in PAUSED state, we remove the surface and we destroy the pipeline, the surface is set to a wrong state, and Android is not able to use it anymore. In the logs joined below, we see that the thread that runs the GST loop issues an eglTerminate() which does not happen on the « normal » use-case described above.

Below are the log generated by our app, do you have any hint on what’s going on there ? Do we made a bad use of the pipeline or is there a bad behavior in glimagesink ?

Thanks in advance for your help

Best regards,

Damien.
