Trying to use dsp_set_timestretch in plugin

(1/1)

sidnancy:
Hello, when I attempt to use rb->dsp_set_timestretch in a plugin, I get:

error: ‘const struct plugin_api’ has no member named ‘dsp_set_timestretch’

when trying to compile for the Emulator.

I was able to use timestretch in the emulator through the standard 'Now Playing' context menu, so I know the code works in general in the emulator.

Any suggestions?
Has anyone been able to get dsp_set_timestretch working in a plugin?

saratoga:
The plugin API probably doesn't export that function, although there is no reason it shouldn't.  You can add it to the plugin_api struct in plugin.c/.h.

sidnancy:
It looks like it does export it.

Checking the API, I see that there is already this:

 #ifdef HAVE_PITCHCONTROL
    void (*dsp_set_timestretch)(int32_t percent);
#endif

in plugin.h and this:

#ifdef HAVE_PITCHCONTROL
    dsp_set_timestretch,
#endif

in plugin.c

I've tried removing the ifdefs  or defining HAVE_PITCHCONTROL as 1 or true and  the whole plugin crashes with this error on startup:

SDL_WaitEvent() error
X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  4 (X_DestroyWindow)
  Resource id in failed request:  0x2023c
  Serial number of failed request:  121
  Current serial number in output stream:  121

On the target (ipod mini)
it dies at plugin start up with error message:

Undefined instruction a
bt pc: 0x000CF364, sp:
bt end


Any suggestions would be appreciated.
