Hi Flavio,
I am still not able to reproduce the seg-fault. Is seg-fault happening always ?
Please find my reply to your queries inline below.

Thanks & Regards,

Yep, it's happening always i use the edje_player with the multisense
example.

The problem is:

+   length = count * sizeof(RemixCount);

it makes length be greater than PA_PLAYER_BUFFERLEN then:

+        *(player->playbuffer + i) = (PLAYER_PCM) value;

will access invalid memory.

I rewrote this function and worked as expected. Please check if it makes sense.

static void
pa_player_playbuffer(RemixEnv *env __UNUSED__, PA_Player_Data *player, RemixPCM *data, RemixCount count)
{
   int ret;
   RemixCount i, j;
   RemixPCM value;
   size_t length, total_written;

Re: [E-devel] enlightenment-devel Digest, Vol 74, Issue 116

Hi,

I would like to set context for new feature haptic/vibration play in multisense.
As we know multisense feature is already in edje which support only audio play.
In this patch, I am adding haptic play support in multisense module.

Regards,
Prince

Hi,

Please review the attached patch for new feature haptic/vibration support added to edje multisense module.
This patch includes a sample haptic module which shows the haptic input parameters. This module can be
replaced with an actual haptic interface for haptic effect.
Change Description:
1. New Feature: Haptic play support added to edje multisense module.
2. Multisense support enabled by default.
3. Disabling of Multisense module initialization/shutdown(include remix module initialization which
is required only during runtime) in EDC compilation mode.

there was no attachment :-)

Also, don't just patch Edje.  Raster now wants a ecore_audio to
abstract audio from multisense and later be usable from outside it
(I've heard Stefan is working on that). Then it would be nice to have
the ecore_haptics to provide the haptics feedback, and that used by
Edje.

Getting things right from the beginning are way less painful than fix
it later ;-)

actually I'm going to be working on ecore_audio. :-)

I'm currently looking at edje_multisense to understand what is needed.
Having haptics support in a separate library rather than inside edje 
makes sense to me as there are probably more users of that API.

Agreed, though the definition of "right" might evolve over time. :-)
