hi:
i bring up the raw8 sensor,1024*768 30fps,then v4l2-ctl -d /dev/video0 -V --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100. I didn’t get the frame rate,
the trace log upload,please check the log,thanks. trace.log (339.0 KB)
even though there’re FS/FE in the VI tracing logs, there’s no CHANSEL_PXL_SOF/ CHANSEL_PXL_EOF to indicate a good frame received by VI engine.
besides, CHANSEL_NOMATCH is outputting with 0x549, is your Raw8 as RGB888? if yes, the data-type should be 0x489
hi:
raw8: data type: 0x2a
now i can get frame rate,bug the kernel log have a log error
tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 0, flags: 0, err_data 131072,
upload the log,please check log,thanks trace-1.log (961.1 KB)
may I confirm what’s the frame-rate reported below v4l2 pipeline? is it as same as your sensor capability? $ v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100
discarding frame logs it’s sometime a warning messages, due to unsuccess capture state, it’s dropping frames and issue a requeue for new buffers.
since it looks okay by checking reported frame-rate, could you please setup a terminal for gather logs, i.e.$ dmesg --follow
