Sony A7M4 camera Could not get photo path or name

[SiuyuenChow]

we want to connect Sony a7m4 protocol is "ptpip" model is "PTP/IP Camera"

gp_camera_new === 0 gp_abilities_list_new === 0 gp_abilities_list_load === 0 gp_port_info_list_new === 0 gp_port_info_list_load === 0 gp_port_info_list_count ===== 2 gp_port_info_list_free ===0 gp_abilities_list_free === 0 gp_setting_set ptpip === 0 gp_setting_setp ptp2 ===0 gp_camera_init ====-7

i dont know why ,error == -7 (Generic I/O error),

Did I set it wrong?

Please help,thanks.

[SiuyuenChow]

I solved the problem,

but the new one come in

---

The new question is

call gp_camera_wait_for_event

get type == GP_EVENT_FILE_ADDED

name = "capt0000.jpg" folder = "/"

Contexterror
You need to specify a folder starting with /store_xxxxxxxxx/

i search question

https://github.com/gphoto/libgphoto2/issues/671

Is this setting causing it? gp_setting_set("ptp2","capturetarget","card");

[SiuyuenChow]

here is the log

you will need to download this file right afterward.

if you could share the code snippet from wait_event file_added to download?

[SiuyuenChow]

you will need to download this file right afterward.

if you could share the code snippet from wait_event file_added to download?

the code is if (evttype == GP_EVENT_FILE_ADDED) { path = (CameraFilePath*)evtdata; fd = open (path->name, O_CREAT | O_WRONLY , 0644); retval = gp_file_new_from_fd(&file, fd); }

It was always ok with Canon, now it's not work with SONY. Did I make a mistake here?

The other errors are just as printed in the previous log

[msmeissn]

And then you run gp_camera_file_get(camera,path->folder,path->name,GP_FILE_TYPE_NORMAL,file,context); or similar?

which libgphoto2 version do you have?

[SiuyuenChow]

And then you run gp_camera_file_get(camera,path->folder,path->name,GP_FILE_TYPE_NORMAL,file,context); or similar?

which libgphoto2 version do you have?

call gp_camera_file_get_info ,canon 200D,5D4,6D,6R is work.

My logic goes something like this, I listened on GP_EVENT_FILE_ADDED and then downloaded the photo via gp_camerA_file_get_info

But I didn't even get the photo information, so I didn't follow the download logic

[msmeissn]

can you just try gp_camera_file_get instead? but the info should also be available, weird. (if that error appears it means the just downloaded image was not cached correctly.)

[msmeissn]

Also capturetarget setting should not cause it, although /capt0000... would be SDRAM and not CARD captured.

yup, I thought it was weird, too,

[SiuyuenChow]

Capturetarget SET SDRAM or CARD, same result

I'll try gp_camerA_file_get later

keep in touch

Since there is no special swift version now, I want to package Gphoto into swift version in the future

[SiuyuenChow]

@msmeissn hello, i try this

    case GP_EVENT_FILE_ADDED:
        path = (CameraFilePath*)evtdata;
        printf("File added on the camera: %s/%s\n", path->folder, path->name);

        retval = gp_camera_file_get_info (camera, path->folder, path->name, &info, context);
        printf ("   info reported flags: %d\n", info.file.fields);
        if (info.file.fields & GP_FILE_INFO_MTIME) printf ("    info reported mtime: %ld\n", info.file.mtime);
        if (info.file.fields & GP_FILE_INFO_SIZE) printf (" info reported size: %ld\n", info.file.size);
        if (info.file.fields & GP_FILE_INFO_TYPE) printf (" info reported type: %s\n", info.file.type);

        fd = open (path->name, O_CREAT | O_WRONLY | O_BINARY, 0644);
        retval = gp_file_new_from_fd(&file, fd);
        printf("  Downloading %s...\n", path->name);
        retval = gp_camera_file_get(camera, path->folder, path->name,
                 GP_FILE_TYPE_NORMAL, file, context);

        printf("  Deleting %s on camera...\n", path->name);
        retval = gp_camera_file_delete(camera, path->folder, path->name, context);
        gp_file_free(file);
        free(evtdata);
        break;

we did not set the info for the sdram captured files, i have added that now to current git. Please test :)

workaround in your code if you cannot update would be to avoid the get_info call

[SiuyuenChow]

@msmeissn hello, I have no idea to solve this problem, can you provide me with the logic of thinking? thanks Best wishes

[Entropy512]

Looking at this, I'm scratching my head at file_list_func - it makes comments like "There should be NO files in root folder" but that's exactly the case for capture to SDRAM.

In my case, I'm doing a capture-and-download using Mr. Easterbrook's python bindings, which somehow seems to be skipping file_list_func (probably by directly retrieving the object via its handle?).

[msmeissn]

in virtual sdram capture mode, the images are in /capt0001.jpg and similar named, so the comment is not quite correct.

[msmeissn]

FWIW The capture API returns the path/folder of the captured image, which is then directly downloaded (no need for listing).

[Entropy512]

Yeah, that was working on A7M3 for me, I'm having some issues with M4 but I think it's a completely different issue to what @SiuyuenChow is having, I've been looking through issues to see if it's a known one, but I think mine is different, will need to take more diagnostics before filing an issue.

I plan on filing a separate issue with more logs next week, but have you ever seen a "stale" ObjectAdded event from a capture come in immediately after a second capture?

First capture and download works fine - I see the capture triggered, followed by some waiting for ObjectAdded, which returns a file handle that can be successfully downloaded.

Whether or not I delete the first file, the second capture and download fails - an ObjectAdded event happens immediately with no delay, with the same file handle as the previous capture. GetObject fails with "Invalid object" leading to a segfault (the segfault may be a flaw in the Python bindings and not gphoto2 itself).

Have you ever seen anything like that? I'll provide more data next week once my family leaves (they are visiting all weekend)

EDIT: Never mind, this seems to be a regression in https://github.com/jim-easterbrook/python-gphoto2 - it does not happen with the gphoto2 CLI, I'm not sure why as I don't see any significant changes in the Python bindings and this did work with an A7M3 back last winter...

[msmeissn]

please open a new issue in this case.

the sony have the issue that there is also the "objects in SDRAM" property which needs to be honored beside the objectadded event.

i dont remember stale events, but it could happen.
