I assume fix-csi-interlaced.2 is a newer version, isn't it?
I merged it and I think I can't set the correct config:
media-ctl -r -l '"adv7180 2-0020":0->"ipu2_csi1_mux":1[1],
"ipu2_csi1_mux":2->"ipu2_csi1":0[1],
"ipu2_csi1":2->"ipu2_csi1 capture":0[1]'
media-ctl -V "'adv7180 2-0020':0 [fmt:UYVY2X8/720x480 field:seq-bt]"
media-ctl -V "'ipu2_csi1_mux':2 [fmt:UYVY2X8/720x480]"
media-ctl -V "'ipu2_csi1':2 [fmt:AYUV32/720x480 field:interlaced]"
produces:
"adv7180 2-0020":0 [fmt:UYVY2X8/720x480 field:interlaced]
"ipu2_csi1_mux":1 [fmt:UYVY2X8/720x480 field:interlaced]
"ipu2_csi1_mux":2 [fmt:UYVY2X8/720x480 field:interlaced]
"ipu2_csi1":0 [fmt:UYVY2X8/720x480 field:interlaced]
"ipu2_csi1":2 [fmt:AYUV32/720x480 field:interlaced]
Do I need to patch ADV7180 for field type "sequential"?
It seems setting seq-bt on ADV7180 sets "interlaced" on ADV -> MUX input
-> MUX output. Setting "'ipu2_csi1_mux':2 [fmt:UYVY2X8/720x480]" sets
interlaced on all elements of the pipeline. The effect is a pair of
fields, not an interlaced frame.
