Re: [Swftools-common] Cannon extract images using swfextract

Hi,

please disregard my last post :-(

Sometimes reading the nice and informational comments would really help
to understand the code :-(

Ok, next try:
There was no code to handle the case that the id was an ST_DEFINEBITSJPEG3
but there is only one stream instead of two.
This should fix it

*** 675,682 ****
      else if(tag->id == ST_DEFINEBITSJPEG3 && tag->len>6) {
        U32 end = GET32(&tag->data[2])+6;
        int pos = findjpegboundary(&tag->data[6], tag->len-6);
!       if(pos<0)
            return;
        pos+=6;
        fi = save_fopen(filename, "wb");
        fwrite(&tag->data[6], pos-6, 1, fi);

Sorry,
