What about video? Any examples for using CameraX with video recording coming?

[@khaldounal-nuaimi3594]

I recently used the camera 2 API to build a camera app as part of a university project. I hated every bit of the development process. First of all there are alot of things to account for, i want to develop i a camera app i really don't need to have 2 classes to query the device about its screen size and its resolution output. The one thing that bugged me the most is consistency. I tested the camera app on an HTC u11, samsung note 9, and google pixel 1. unsurprisingly everything worked fine on the pixel BUT the front camera straight up refused to work on the note and the flash refused to work on the htc. After this project i fully understand why instagram and snapchat uses to capture a screen view instead of a photo straight from the sensor. developing android camera app that works well across every android device is semi impossible.

This is amazing! Congrats to the team responsible for CameraX on Google.

Camera2 API was a disaster. Not too hopeful about CameraX - they still like to throw in lots of helper classes for specialized use cases instead of covering the most common uses with defaults. E.g. why not just pass a SurfaceView reference to the builder for the preview destination? Was there a need to introduce a new ImageProxy class instead of using existing ones? And if so, why not place useful methods in it, e.g. rotate & crop the image?

[@alwayz247]

How come Google Pixel devices don't have full CameraX support? Why can I not use Google Camera's night mode (Night Sight) by using CameraX API?

[@realcrys]

I just spend a day today trying to bring camera2 to live for my image analysis demo app. Was a wasted day. Thank you so much.

[@pemadechen9901]

I m just glad I m understanding what is being said .the very fact is making me feel happy😄😄😄

[@lotfii]

So will we eventually se improvement on Instagram stories camera?

[@cruxinterfaces]

Very informative and well done, we will be at Knowledge Fest Thank you for the content

[@xreasezanmoody7633]

I have no idea what this is but I sat through the whole video real interested😐.

[@karatuno]

are the vendor extensions working right now?

[@MauriceWilliams]

Wow! CameraX is impressive!

[@scottbiggs9846]

Hmmm, is it just me, or does the code not even come close to compiling (even after updating the gradle, etc.). The first line at 9:59--PreviewConfig doesn't have a Builder() element. I'm guessing that the libraries have already changed so much that these examples are obsolete. If so, how about an update?

[@user-ud1gn5us4i]

address to download the keynote?

[@mohammadsajibalseraj9813]

Does Pixel 5a support CameraX vendor extension?

[@WaqasAli-ce2qc]

Well its a really Good Effort by Android but there are still things that needed to be focused on. As there is a flipping issue on front camera, there must be a feature to easily turn on and off mirror image. Also in this api front camera crashes.

[@norlesh]

Can anybody comment on whether or not CameraX is able to access front and back camera's concurrently on devices who's hardware supports it?

[@lynetteford6063]

I am a desperato which textbook can I learn this from I look through computer programming ,cobol language I look like you must know programmer to know what your doing theses books really difficulted I guess I won't be taking any picture on my phone.

[@ptdong]

How to use camerax with external camera??

[@UsmanAli-gb4bn]

i just loved this API

[@lynetteford6063]

Is there a textbook or what.

[@mortezamaghrebi9560]

excellent

[@brijeshmorya9737]

amazing

[@mamitripathy6402]

He it is not easy..to use... No proper documentation is there ... I am finding touchtofocus feature in camerax no documentation is therefor that

[@Pulkit__7]

Now atleast Snapchat app can be improved, only if there engineering team works on this.

[@chrislagos44]

Why are they showing an API thats in alpha

[@AlejandraStamato]

So you can use it and report bugs and suggest tweaks yourself. Be a part of it!

[@garrettkajmowicz]

Because they haven't deprecated it yet.

[@fedeuribito]

Good job Camera X is much better than Camera2

[@hugosalazar6911]

thats the all point

[@AlejandraStamato]

Camerax is a layer on top tho😀 achieving things with camera 2 alone was quite painful
