This fixed it and the content is now there ... relevant things:
Streams:00020001
Video: dss: 36d, timeres: 33333333d, fhsize: 8, fmxsize: 1048558,
phsize: 6, pmsize: 1048576, palign: 1
17: dss: 36d, timeres: 33333333d, fhsize: 8, fmxsize: 1048558, phsize:
6, pmsize: 1048576, palign: 1
So the camera supports PTP v1.1 streams, here the preview stream. (Not sure
what format 17 is, perhaps a different format)
Supported Streams(0x5020):(read only) (type=0x6) Range [0 - 983041,
step 1] value: 131073
This is 0|17 from above (0 = Video, 17 = vendor specific)
Enabled Streams(0x5021):(readwrite) (type=0x6) Range [0 - 983041, step
1] value: 0
Here we would enable the streaming, by setting 1 or so.
Video Format(0x5022):(read only) (type=0x6) Enumeration [1196444237]
value: 1196444237
This is the format we will get, "MJPG" ... meaning concatened
jpeg frames as we currently generate.
Video Resolution(0x5023): error 201b on query.
Video Framerate(0x5025):(read only) (type=0x6) Enumeration
[25000,30000] value: 30000
interval between frames in microseconds...
1.000.000/30.000 would mean around 33 fps.
The whole stream handling is new to me, your camera is the first I see that
supports it.
So there currently is no code in libgphoto2 for it ... although it might not be
hard to add it.
Can you try one more thing:
gphoto2 --set-config 5021=1 --set-config opcode=0x1025,1 --debug
--debug-logfile=stream.log
If it works, it will start endless streaming, so you will need to press ctrl.c
and truncate the logfile before sending ;)
As the streaming is tricky, I can implement over easter perhaps some small non
optimal testcode.
Ciao, Marcus
