What did not worked at you? Screenshot * Stored to /dtv/usb/sda1/Screenshots/20160503191644_DTV1.jpg
That`s all. No need to take care about errors.

[kurt]

Ok.
ALT and OSD methods do not work. I believe that the reason may be just in the appearance of these errors.
Now take screenshots in accordance rcRemap_capture_EF file (TV is UE32ES6307)

Code: Select all

$SAMYGOSODIR/samyGOso -A -B -l $SODIR/libScreenShot.so PATH:/dtv/usb/sda1/Screenshots JPG HD SOURCE ALERT

It works.
In any case, many thanks to the developers for their work. Great job!

[zoelechat]

I'd be surprised any feature doesn't work on E-MST where I first developed lib. Misusage imho
"Failed" on several symbols is expected, in your case they're non-E ones (lib is multi-series...)

[*]JPG - Save capture as JPEG. (Known to cause crash on some TVs, especially H).

As you already mentioned, H series TVs will crash after using JPG parameter. How can I use your great lib with another .so file(that I believe it can be find in the Internet but I am not familiar with Linux) to convert output bmp(2mb file) to JPG(200kb file) on the fly? Is it possible? How?

Note:I want to run SH script that it generate screenshot with helps of your lib and after that convert it to JPG file and delete bmp file after that!

@smart_lover - I'm working on adding a webend component to stream screenshots of your tv. It will be slow, but will convert the image to jpg. I'll let you know in a couple of weeks if you're still interested.

[mad_ady]

Ok, the web component is done, and can be installed from here: viewtopic.php?f=75&t=11881
Example usage: viewtopic.php?f=79&t=11882

It includes a jpeg converter which converts your bmps to jpeg. It works pretty well. I haven't crashed my TV in a week when grabbing an image every 10 seconds. You can grab even faster, but there is an internal rate limit of about 1fps.

Thank you for this App, my experience:
I had Menu with french language, i took a screenshot with PATH SOURCE and ALERT args, works very good!
I changed Menu language to english i took a screenshot with exactly the same args, put the bmp file correctly in the usb device but crash the TV! After reboot i let english language, took a screenshoot and crash again!
Ok, back to french language and works perfectly!

Hi
i have a small question about the libScreenShot library. In the function

Code: Select all

hCTX.SdDisplay_CaptureScreenE(CDSize, tmpBuffer, CaptureInfo);

in ScreenShot.c one can define the Size of the captured image (with CDSize). As I understood from here the maximum native capture resolution is 960x540 pixels.
If i want to capture let say image with resolution of 83x48 only, what image will i get. An internally downsampled image or just a part of the original 960x540 one?
Hope someone can clarify this for me.
Thanks in advance.

[zoelechat]

I think using 83x48 you'll get none of both but only "crap" because you break ratio therefore offset lines (not talking about split bytes )
You can request lower resolution and get (badly) downsampled thumb, but you must use exact multiples of 16:9.
For example 80/45 or 96/54 (==16/9) are ok.
