Hi,
I need to know that the libuvc is updated to the latest version
because it has support to many formats like Bayer.
If not can you please update it to the latest version.

https://github.com/libuvc/libuvc
This is the libuvc latest version repo

New Version on libuvc Stream.c file (https://github.com/libuvc/libuvc/blob/master/src/stream.c)

Thanks in advance

Hi,

We are using Omnivision OH01A10 and OV5640 in our project which supports Raw 10/8 Bayer Formats but this version of libuvc used in your project does not support these formats

Please have a look at the above issue link for more information

Thank You

Isn't it easier to demistify how libraries are updated?

There's not reference about what version jnilibs use

The simpler way to build them I found is: define android sdk and ndk

export ANDROID_SDK="$HOME/Android/Sdk"
export ANDROID_HOME="$HOME/Android/Sdk"
export ANDROID_NDK="$HOME/Android/Sdk/ndk/21.4.7075529"

clone UVCCamera

git clone https://github.com/saki4510t/UVCCamera

get into jni and build directly

cd UVCCamera/libuvccamera/src/main/jni
ndk-build

I make this changes to support latest ndk:

diff --git i/libuvccamera/src/main/jni/Application.mk w/libuvccamera/src/main/jni/Application.mk
index c6f7c2e..45d46a9 100644

latest libraries will be on:

libuvc.so

I recommend to do commits linking with commit on UVCCamera so anyone can bisect if their needed changes are present here.

Let me know if you want this to be included on wiki for general reference

Hi ,
We have found that https://github.com/saki4510t/UVCCamera also contains the old version of libuvc only which does not have support for the bayer formats.

Thanks you

Sorry, it's not my design. If someone want to use latest code, he can clone code himself. My design is: Everyone can download the code and build without any error, then the app works OK. You must clone many codes and find many errors when building, and is angry on this problem. I will check the latest libuvc this week. And I will update this repository: https://github.com/quantum6/Quantum6-Android-USB-OTG-Camera Good luck.

As you mention please Update the Libuvc to the
latest version from this repo https://github.com/libuvc/libuvc

FYI - https://github.com/saki4510t/UVCCamera this Saki Repository also contains the old version of libuvc only Please Dont use that

Thank you once again.

@quantum6 you know better, just to continue demistifying this.

Is UVCCamera used to build the libs?

I just check uvc_mjpeg2* functions.

On original repo there are:

uvc_mjpeg2rgb
uvc_mjpeg2gray

on UVCCamera:

uvc_mjpeg2bgr
uvc_mjpeg2rgb
uvc_mjpeg2rgb565
uvc_mjpeg2rgbx
uvc_mjpeg2yuyv

I check on this repo for symbols on libuvc and looks it uses UVCCamera "fork":

$ nm -gD libusbcamera/src/main/jniLibs/x86_64/libuvc.so | grep uvc_mjpeg2
00000000000122e0 T uvc_mjpeg2bgr
0000000000011d90 T uvc_mjpeg2rgb
0000000000012810 T uvc_mjpeg2rgb565
0000000000012d40 T uvc_mjpeg2rgbx
0000000000013270 T uvc_mjpeg2yuyv

https://github.com/libuvc/libuvc looks just like a regular lib, without any android ndk support.

libuvc last release is on 2017

last commit on UVCCamera for libuvc is 306ad50 (2016)

There're files called *_original in that could help to find the real libuvc commit
There're changes on libuvc not present on original repo.

fork libuvc and start a branch android or similar to show the needed changes would be great, even contribute back to libuvc

Same for the rest of native libraries

Not sure what that means. Depend on a binary files out of nowhere with changes on top of open source library.

It would be great to push the sources to create those binaries in another repo, but you know better, just suggesting if that helps to maintain the project

@quantum6 just if that helps is ok whatever you do, focus on your priorities. Just if you can publish your sources as they are, we can help to rework on top of a know version
