Maybe you need to check if your ARM board could support float point numbers correctly. Take a look at function swfdec_matrix_ensure_invertible(), it's not big. --zou <div class="gmail_quote">On Thu, Jan 21, 2010 at 7:29 AM, Paul Brooker <<a href="mailto:paul@thefunnyfish.net">paul@thefunnyfish.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div><div></div><div class="h5">Paul Brooker wrote: > Hi, > Im trying to thumbnail a swf file based on this found at > <a href="http://www.mail-archive.com/swfdec@lists.freedesktop.org/msg00821.html" target="_blank">http://www.mail-archive.com/swfdec@lists.freedesktop.org/msg00821.html</a>. > > #include <stdlib.h> > #include <stdio.h> > #include <swfdec/swfdec.h> > #include <cairo.h> > > void swfdec_player_save (SwfdecPlayer *player, guint width, guint > height, const char *filename) { > cairo_surface_t *surface; > cairo_t *cr; > surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32, width, > height); > cr = cairo_create (surface); > swfdec_player_render (player, cr); > cairo_destroy (cr); > cairo_surface_write_to_png (surface, filename); > cairo_surface_destroy (surface); > } > > int main(int argc, char *argv[]) { > char *input = argv[1]; > char *output = argv[2]; > SwfdecPlayer *player = swfdec_player_new(NULL); > SwfdecURL *url = swfdec_url_new_from_input(input); > swfdec_player_set_url(player, url); > swfdec_url_free (url); > swfdec_player_set_size (player, 800, 480); > swfdec_player_advance(player, swfdec_player_get_next_event (player)); > swfdec_player_save(player, 800, 480, output); > return 0; > } > > Using this i get a blank transparent png output as reported by the > original poster.

The only differences towards the end of the debugging output.

From then on the invalidating regions are incorrect and are set to 0,0->1,1. Im not clear on the inner workings so not sure what is calling the functions incorrectly. Im suspicious of liboil as the oil_test produces failures of some conversion functions.
