Animation/Video HEIC is not fully supported

[LoveStep]

Thank you very much for your hard work and world best heif plugin. All Nokia HEIC/HEIF examples working fine, but with a small exception.
http://nokiatech.github.io/heif/examples.html

1. "Image bursts"
   Each file contains a short video, thumbnails of each frame in the video and high quality version of the “selected best shots” from an image burst.
   http://nokiatech.github.io/heif/content/image_sequences/bird_burst.heic
   http://nokiatech.github.io/heif/content/image_sequences/rally_burst.heic

"bird" - provides a choice opening only 4 intra(?) frames from 90 all frames.
"rally" - provides a choice opening only 4 intra(?) frames from 60 all frames.

2. "Image sequences"
   Sequence of images can be stored just like Cinemagraphs or Animated GIFs.
   http://nokiatech.github.io/heif/content/image_sequences/starfield_animation.heic
   http://nokiatech.github.io/heif/content/image_sequences/sea1_animation.heic

open only first intra(?) frame from all available frames.

This is rather a feature request for upstream libheif:
https://github.com/strukturag/libheif

We can keep it here for reference.

@farindk do we have support for such images on the roadmap?

This is not a high priority item, because I do not see anybody using this yet.
When there are more files around apart from the Nokia streams, or if anybody makes a good case why they will need it, I will add support.

Open the animation it would be nice, of course, but it's really not important at this moment. In any case, thanks!

I suggest reporting to upstream.

Waiting for animation support. Some customers using my iOS framework request the HEIC animation support.

@dreampiggy could you please provide some sample animation files besides the Nokia streams? Best would be to open an issue at upstream libheif (https://github.com/strukturag/libheif) and attach the samples there.
