Is i.MX 6S support H/W jpeg decoding?

[yongsukjang]

I'm searhing H/W jpeg decoding information. But I can't.

But, find some interesting samples at "usr/share/imx-mm/video-codec/examples".

@ /rootfs/usr/share/imx-mm/video-codec/examples$ ls
bmp-dec  deinterlace  gif-dec  h264-dec  jpeg-dec  jpeg-enc  mpeg2-dec  mpeg4asp-dec  png-dec  uniform-test  vpu

It seems jpeg-dec example with VPU. But it's not compiled with many errors.

This is my questios.

1. Is i.MX 6S's VPU support H/W jpeg decoding?
2. If possible, how can I get running example and code?

Thanks for your attention.

1. It does not support H/W JPEG decoding.

2. Please check this link https://community.freescale.com/docs/DOC-93790

Hope this can help others with the same question:

VPU can decode JPEG in JFIF format, but not for those in EXIF format.

Seems that there is already a element doing the transform http://gstreamer.freedesktop.org/data/coverage/lcov/everything/gst-plugins-bad/gst/jpegformat/gstjif...
