thumbnailer | Go media thumbnailer | Computer Vision library

Basically, before uploading an image to the firebase, I'm trying to control the input as:

I am trying to write a thumbnail provider extension (on macOS) that accesses the Core Data store of the main application, shared via an app group, to find images to base icon thumbnails on. This worked fine until I added one attribute to the Core Data model. Now the extension always crashes with An error occurred during persistent store migration and attempt to write a readonly database.

Creating a new default model version and deleting the Core Data Store doesn't help. Somehow the thumbnailer extension still thinks that the store written by the main application uses an earlier model, which makes no sense.

If I set shouldMigrateStoreAutomatically to NO, I get The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store.

If I set readOnly = YES on the NSPersistentStoreDescription, I get The file couldn’t be saved because you don’t have permission. which I think may be a concurrency isse, caused by lots of thumbnail provider threads trying to migrate the store all at once.

EDIT: Original code here: https://github.com/angstsmurf/spatterlight/blob/quicklook/SpatterlightThumbnails/ThumbnailProvider.m

I'm using easy-thumbnails, the original file is saved correctly but the thumbnails are being saved with a duplicate file extension:

I am using Djano 3.1, Python 3.6, easy-thumbnails 2.7 and django-taggit 1.3

I want to create a fixtures data file for my model.

Here is my (simplified) model:

I want to write a short program, which triggers the Thumbnail creation for all pictures on my network share recursively (e.g. over night) - so that when I access a folder in Thunar, the thumbs are displayed immediately.

I would say, that when I can access the API via gdbus call, then the system is setup correctly:

I have heard its a conventional practice to store program dependent files in /usr/share/application-folder in linux. So I'm trying to do it in my c program in a function called load_interface_files() for example. I am not sure if this is a good practice or not, I've heard about creating configuration files for this kind of issues.

Anyways, here's the the code I wrote to make a directory in /usr/share.

So I am using fallback default image to avoid 500 error and it is not successful. I keep getting the same error "InvalidImageFormatError: The source file does not appear to be an image".

In my case I try to thumbnail an image that does not exist. But it is assumed that if the image does not exist it should use the one that is in default as fallback. Any ideas? Someone who has happened in the same way and found a solution? In my case this is my code {% oscar_thumbnail child_image.original|default:'image/default.png' "450x450" format="WEBP" padding=True as thumb_child %}

I am migrating from sorl-thumbnails which comes by default with django_oscar for easy_thumbnails. The tag OSCAR_THUMBNAIL is used by django_oscar and oscar replaces it with the thumbnailer that is in settings in this case easy_thumbnails. I have debugged the code, and it is entering the easy_thumb classes well ... and the parameters are arriving correctly. The thing is, it doesn't make me fallback when the image it's trying to process doesn't exist. I have a database with products that have associated images, many of these do not exist in my local environment, because in production they are in s3, and I do not have my settings configured for s3 in my development environment. But hey, the question is that it should fallback when there is no image, or there is a reference to an image that does not physically exist. With which I intend to do fallback if it exists but it keeps giving me error 500 and it does not show me the page, I get the django page with the exceptions. Oh and I've also tried the native easy_thumb tag ...

Any ideas? Thanks in advance!

I'm making a movie player with libav. I have decoding video packets working, I have play in reverse working, I have seeking working. All this works no an x86 android emulator, but fails to work on a real android phone (arm64-v8a)

The failure is in sws_scale() - it returns 0. The video frames continue to be decoded properly with no errors.

There are no errors, warnings, alerts from libav. I have connected an avlog_callback

I want to display a String of names in the text view of recycler view. the .xml of this step is below
