Hi Nicolas,

1) Do reverse playback seek is supported with gst-v4l2 decoders and ever
verified on any of the supported hw platforms.

If not supported with gst-v4l2 decoders currently then let us know if you
have any plans to support it with gst-v4l2 decoders?

NOTE: Tried to check reverse playback with gst-v4l2 decoder on Exynos but
found not working. 

2) Also, with earlier communication on gst-devel thread titled "Gstreamer
V4l2 Codec elements for video encoders/decoders" you informed that currently
the most tested platforms (non scientific) for gst-v4l2 decode/encode
implementation would be:
 - IMX.6/8 CODA driver
 - Qualcomn Venus driver (dynamic resolution is broken)
 - Exynos (some stability issue, which seems to be in IOMMU driver)
 
Do gst-v4l2 decode/encode implementation now been verified on any other hw
platforms(specifically for 64-bit) other than the listed above?

-Thanks
