AM5726: Gstreamer capture resolution

Christian Alford

Part Number: AM5726

Hi,

Quick question for the team:

I have found that using g-streamer, we can support capture resolutions up to 1920x1080 only.

The video capture supports resolutions up to 1920x1080, and video formats NV12 and YUY2.  I could find this on one of the TI’s wiki links for AM57xx,

http://developer.ridgerun.com/wiki/index.php?title=Gstreamer_pipelines_for_AM572x#VIDEO_CAPTURE_.28V4L2SRC_-.3E_VIP_-.3E_VPE.29

Can you please verify this?. Our capture resolution is 4080x992 and format is YUYV-4:2:2, 8-bit.

Regards,

Christian

    Hi Christian,

    The VIP hardware IP can support 4K capture if no other processing like color conversion or scaling is enabled in VIP, however the VIP software driver restricts the size limitation to 2048x1536. You can try modifying the macro for max width limitation in vip.c file (line #54 - MAX_W) inside linux driver/media/platform/ti-vpe/vip.c file and see of that takes care of it. If it doesn't, please share the kernel log and we can look into other places if there's more dependency in driver code.
