Combining filters with buffer does not work normally

[Umio-Yasuno]

Hello.
I tried to implement the combination of filters by referring to the link below.
https://radeon-pro.github.io/RadeonProRenderDocs/en/rif/combining_filters.html

The unbuffered version works fine.
However, the buffered version does not work normally

The unbuffered version works fine if not combined with a size-affecting filter (e.g. Resampling, Rotate, Flip), so I'm going to use that for now.

/*
 *    without buffer
 */
   
   if (i % 2 == 0) {
      rifCommandQueueAttachImageFilter(queue, filter[i], inputImage,  outputImage);
   } else {
      rifCommandQueueAttachImageFilter(queue, filter[i], outputImage, inputImage);
   }

   if (i == filter_count - 1 && i % 2 == 1) {
      rif_image_filter fill_filter = nullptr;

      rifContextCreateImageFilter(context,
                                  RIF_IMAGE_FILTER_CONVERT,
                                  &fill_filter);

      rifCommandQueueAttachImageFilter(queue, fill_filter, inputImage, outputImage);
   }

/*
 *    with buffer
 */
   if (i == 0 && filter_count == 1) {
      rifCommandQueueAttachImageFilter(queue, filter[i], inputImage, outputImage);

   } else if (i == 0) {
      rifImageFilterSetParameterImage(filter[i], "srcBuffer", inputImage);

   } else if (0 < i && i < filter_count - 1) {
      rifImageFilterSetParameterImage(filter[i], "srcBuffer", (rif_image)(filter[i-1]));

   } else if (i == filter_count - 1) {
      rifCommandQueueAttachImageFilter(queue, filter[i],
                                       (rif_image)(filter[i-1]), outputImage);
   }

@Umio-Yasuno thanks for that test.
This is expected to fail as we don't support joining the bloom effect with other effects.
However we currently don't report that information to developers and it is big problem on our side. We will expose that better in our next version
Most of our filter can be combined, only a few cannot
