[Swftools-common] a bug about swfextract

[sunny]

Dear Sir or Madam:

         It seems that there is a bug in swftools.c (line 489, under swftools-2005-10-16-1929\lib\modules\):

         case ST_DEFINEBUTTONCXFORM: {                // the operation for case ST_DEFINEBUTTONCXFORM is not correct.

             int t;

             callback(tag, tag->pos + base, callback_data);

             for(t=0;t<4;t++) {

                   int flags;

                   callback(tag, tag->pos + base, callback_data);

                   swf_GetU16(tag); //sound id

                   flags = swf_GetU8(tag);

                   if(flags&1)

                       swf_GetU32(tag); // in point

                   if(flags&2)

                       swf_GetU32(tag); // out points

                   if(flags&4)

                       swf_GetU16(tag); // loop count

                   if(flags&8)

                   {

                       int npoints = swf_GetU8(tag);

                       int s;

                       for(s=0;s<npoints;s++)

                       {

                            swf_GetU32(tag);

                            swf_GetU16(tag);

                            swf_GetU16(tag);

                       }

                   }

             }

        } break;

 

Best wishes,
