segfault armhf #22

Closed grafoo closed 7 years ago

grafoo commented 7 years ago

hi! i compiled the example from https://github.com/arturoc/gstreamer1.0-rs/blob/master/examples/playbin.rs for armv7-unknown-linux-gnueabihf but unfortionally it segfaults when e.g. using it like ./playbin http://www.podtrac.com/pts/redirect.mp3/traffic.libsyn.com/jnite/bsd-0166.mp3

can this be related to the gst_init in https://github.com/arturoc/gstreamer1.0-rs/commit/7a435054aafac1335a7f6761ea92262a43658fcf ? i also tried your new approach with c_char but that didn't work either.

here is the processor information just for completeness:

there could be a bug in that example, usually loading resources from the web is more complex than loading local resources. can you try to load something locally and see if that crashes too? also can you debug the application and post the stack trace?

thanks!

sorry for the delay :D

but finally:

Hi,

same problem on x86 (32 bits). The main problem is that the Message parse function (src/message.rs) matches always the default case (unknown message).

I suppose that one of the field of the Struct__GstMessage is defined with a type that does not match the actual C type used by gstreamer on 32 bits platforms.

Regards.
