Unable to capture video on iMX8MP with Android 11

[Charled]

Hi,

I am using a custom board using i.MX8MP chipset, and based on the reference EVK board. I can capture images with the camera, but not video. The issue is the same on the EVK board.

I am using Android 11.0.0_2.6.0.

The error I can see in the logcat is:

E/IMXC2VideoEncoder: mEncoder OpenDevice fail
E/StagefrightRecorder: Failed to create video encoder

And in the dmesg, I can see that (not sure if this is related or not):

hantro_enc driver probe fail! nr=0xb8000000 ret=-1. Use normal mode.
hantroenc: NO ANY HW found!!
hx280enc: module not inserted
hantro vc8000e: init failed
hantro vc8000e probe failed
vpu driver probe fail! nr=0xb7000000 ret=-1. Use normal mode.
hantrodec: Unknown HW found at 0x 38300000
hantrodec: module not inserted
hantro: hantrodec_init failed
hantro probe failed
vpu driver probe fail! nr=0xb7000000 ret=-1. Use normal mode.
hantrodec: Unknown HW found at 0x 38310000
hantrodec: module not inserted
hantro: hantrodec_init failed
hantro probe failed

Does anyone faced such issue?

Any idea why it appears, and how to fix that?

Thanks,

Charles-Edouard

Hello @joanxie,

I have already done this, as mentioned in the document, but without success. Please note that capturing photo works well, and only video is not working.

current bsp only supports  supports daA3840-30mc, did you use this basler? if no, maybe current bsp couldn't support it yet

Hi @joanxie ,

Yes, I have used the Basler camera, with the imx8mp_evk board, and Android 11.0.0_2.6.0.

I can reproduced the same issue also with our own board and another camera device, but here, considering I have the issue with your standard configuration, I would expect some interesting suggestion to find and fix the problem.
