[PATCH] media: venus: only set H264_TRANSFORM_8X8 on supported hfi versions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Setting the H264_TRANSFORM_8X8 property only works on HFI versions
>=4xx. The code used to unconditionally set the property in
venc_set_properties, which meant that initializing the encoder would
always fail unless the hfi_version was >=4xx.

This patch changes venc_set_properties to only set the
H264_TRANSFORM_8X8 property if the hfi version is >=4xx.

I have an APQ8016-based board. Before this patch, the Venus driver
would simply fail with EINVAL when trying to request buffers
(VIDIOC_REQBUFS). With this patch, encoding works
(tested using gstreamer's v4l2h264enc).
