            Compress & Upload large videos to Google cloud storage using Flutter/Dart
            Asked 2022-Feb-20 at 03:41

            There are a couple of notable packages on pub.dev that offer video compression. I've tried them, and other sketchy packages, and none work well once a video gets around 300MB. They crash or have other issues on various platforms and hardware. Namely, video compress and light compressor. The GH commits and support are concerning as well on the packages I've seen for video compression in pub.dev. PR's not being pulled in and issues not being resolved in a timely manner and some quite serious for recent android APK updates. So not something I want in my dependency stack.

            I am uploading to Google Cloud Storage using FlutterFire. While my code does upload using FireBaseStorage upload task it does not have any ability to compress on the client side or handle background uploading when the app is closed.

            So, currently on the server side, I have a GCF that triggers on file uploaded. Then I use nodejs ffmpeg, which is baked into GCF's to compress server side and convert to H264. And finally delete the original large upload video and save the compressed video to storage.

            This solution works, but depending on a user's connection and whether they are on wifi, can take an awful long time and when it fails or the user closes the app, my current solution is useless.

            I wish there was a solid native library on Android and iOS, that I could tap into, to confidently perform compression and conversion from any format to H264 and also allow uploading, whether my app is closed or in the background, to GC storage. Any thoughts? I wish this was standard in FlutterFire's cloud storage handling!

            I have yet to test flutter_ffmpeg, but only because some have said it runs so slowly on client. So again, Flutter/Dart can access natively written code, but I don't know where to start on Android/iOS to do this the right way. And I understand this is what some of the packages are doing, but they do not work with large videos, so I'm hoping someone can point me in the right direction on Android and iOS.

            My code for handling upload tasks to GC storage.

            Answered 2022-Feb-20 at 03:41

            I did resolve, to some degree, my original post's questions and frustrations by using the ffmpeg_kit_flutter_full_gpl package on the client side, and then ffmpeg again in GCF on the server side. In summary:

            • Within 60 seconds, I can now compress a 2 minute video by 90% before uploading to firebase storage.
            • Using onFinalize via GCF on the server side I run ffmpeg again on the uploaded video and gain another 77% reduction in file size on the server side without any loss in video quality.
            • My solution does not yet upload while the app is closed.
            • On the client side, this solution requires setting the camera ResolutionPreset to high (720p), rather than max, which can be a minimum of 1080p, and setting the ffmpeg -preset veryfast rather than the medium default.

            Camera & ffmpeg solution settings:

            Transcoding results stats for 2 minute video:

            • Before transcode: 255MB
            • After client side transcode: 25MB (90% decrease in size before upload)
            • Time to transcode: 60 seconds
            • onFinalized GCF ffmpeg transcode: 19MB (77% reduction in size)
            • In total a 93% reduction in size while keep high quality 720p video.

            flutter_ffmpeg is archived, the new ffmpeg flutter package is ffmpeg_kit_flutter.

            That being said, I used ffmpeg_kit_flutter to build my solution on the client side, rather than the server side, and transcode the video before uploading.

            Cons:

            1. Doubled my app size to use ffmpeg, because I needed access to both lame and x264 so I had to install the full-gpl package to gain access to these libraries.
            2. A two minute video can take up to 60 seconds to transcode.

            The pros:

            1. Low bandwidth connections will operate much better after a video is reduced in size by 90%.
            2. Large videos will transcode and ffmpegkit does not crash like other flutter packages I've tried.
            3. The second pass with ffmpeg on GCF gains another 77% reduction in size taking a video of 100's of MB's down to just 10-20 MB max for eventually delivery.
            4. Costs lower on the front and back end.

            So, you'll have to decide if the pros outweighs the cons and if 720p is high enough quality for playback. For me 720p looks perfect for video playback on a mobile phone and 1080p or higher was big time overkill.

            I've provided sample code (not full classes) to give anyone looking to implement my solution a try. It became very important, due to the amount of time to transcode, to display a progress meter so the user does not give up on the process. You'll see my simple solution to displaying transcoding progress.

            The Firebase Function deployment failed because it cannot find the image built based on your function app. There might be a problem building in your app, it could be your dependencies or files.

            I replicated your issue, received the same error and solved it. There's a problem with the package.json file and package-lock.json. If you just add(without installing) your dependency in package.json you should delete or remove your package-lock.json that will be found in function directory before you deploy it again using the deployment command:

            Cloud Functions uses another product called Cloud Build to build the server images that actually get deployed. Those images are stored in Cloud Storage, and that storage is billed to your account.

            Read more about it:

            Watch:

            You should be able to locate and delete the files manually in the Google Cloud console. But it sounds like there is a bug here with the files not being cleaned up automatically, so you contact Firebase support directly.

            Receiving HTTP 401 when accessing Cloud Composer's Airflow Rest API
            Asked 2021-Dec-04 at 01:32

            I am trying to invoke Airflow 2.0's Stable REST API from Cloud Composer Version 1 via a Python script and encountered a HTTP 401 error while referring to Triggering DAGS with Cloud Functions and Access the Airflow REST API.

            The service account has the following list of permissions:

            • roles/iam.serviceAccountUser (Service Account User)
            • roles/composer.user (Composer User)
            • roles/iap.httpsResourceAccessor (IAP-Secured Web App User, added when the application returned a 403, which was unusual as the guides did not specify the need for such a permission)

            I am not sure what is wrong with my configuration; I have tried giving the service account the Editor role and roles/iap.tunnelResourceAccessor (IAP-Secured Tunnel User) & roles/composer.admin (Composer Administrator), but to no avail.

            EDIT: I found the source of my problems: The Airflow Database did not have the credentials of the service account in the users table. However, this is unusual as I currently have a service account (the first I created) whose details were added automatically to the table. Subsequent service accounts were not added to the users table when they tried to initially access the REST API, thus returning the 401. I am not sure of a way to create users without passwords since the Airflow web server is protected by IAP.

            As mentioned in the comment section by @LEC this configuration is compatible with Cloud Composer V1 which can be found in GCP Documentation Triggering DAGs with Cloud Functions.

            At the moment there can be found two tabs Cloud Composer 1 Guides and Cloud Composer 2 Guides. Under Cloud Composer 1 is code used by the OP, but if you will check Cloud Composer 2 under Manage DAGs > Triggering DAGs with Cloud Functions you will get information that there is not proper documentation yet.

            This documentation page for Cloud Composer 2 is not yet available. Please use the page for Cloud Composer 1.
