Uploading of videos never ends

[internetmosquito]

Many mentors complain that they can't upload videos because they're kept uploading forever

We need to know why this happens, from Joshua, only 2 out of 20 videos were uploaded

[internetmosquito]

More occurences, based on Joshua's email

I have taken the labtab from Los Altos to help upload week one videos. Fredy was only working week one. Ryan worked week two and that is when I retrieved the labtab after his week was over to catch up. I noticed when I went into the Gallery folder that there were no videos at all stored. I logged in with his account and saw the videos in his "video list" but only 3 were showing a green 100%, all other videos (about 50 or so) were still in the red "uploading."

I connected the tablet to a laptop and asked to see all hidden files but there were no videos to be found.

In the video list on the tablet, videos marked 100% did not show a thumbnail in the video display as if there were no videos in the tablet to pull images from. Do you think they were erased and that is why I cannot find any in gallery as well as the reason why the thumbnail is not showing for 100% uploaded videos?

Adding logs, @kapoorutd please let me know what you see wrong here. it was mentor Fredy in Los Altos lab. 1530816687159_logs.zip

However, last time as per our diagnosis in android app I found below mentioned reason regarding this issue - The Category and Knowledge Nuggets criteria corresponding to Category and components criteria in wizbots api doc are not available like Theme option in Category and Brace Strength option in components are not available in wizbots api doc, similarly Planning option in components is not available in Knowledge Nuggets in android application. Please find below the url response which represents if we put criteria which are available in api doc the request goes successful otherwise we are getting 400 status code(Bad request).

and Category option from String-array which is mentioned in string.xml file in res/value folder -

[internetmosquito]

@kapoorutd Thanks for reseach, but still unsure what's going on here:

1.- Not enough memory issue? Do we have a memory leak? 2.- So whenever you choose any other category than Challenge, creating a video fails? 3.- How is metadata endpoint related with category? I get this calling that endpoint

I see no categories anywhere? Not sure what you're trying to say here

[alexey-ku77]

There is still used old categories, being added to app assets as string array. I already have told to trim it for now to version that is supported by server.

[internetmosquito]

@alexey-ku77 and what version would that be? What is the list of supported categories as of today?

[alexey-ku77]

@internetmosquito Production now supports - challenge, contraption, game. It can be checked at https://wizbots.com/api/doc#!/projects/post_project_collection

[alexey-ku77]

@internetmosquito I think we should probably extend metadata endpoint to include categories too. Also I have thoughts on server/client app compability: As we can see - app and server releases are out of sync. This why we have a mess with nuggets and categories. To get rid of that - app should not be storing categories and nuggets in static assets. Only fetched from server and stored in local database. I am not familiar with the features app provides. But once it have special behavior for some categories or nuggets - app should provide feature based functionality. I.e. if category or nugget is missing - feature module is disabled and vice versa.

[internetmosquito]

@alexey-ku77 agreed, and I always assumed all this data was obtained from API

@alexey-ku77 please extend metadata to include categories in the response

@kapoorutd Please use this endpoint to get categories available. Store it in database and update whenever we have FCM working

[alexey-ku77]

@internetmosquito ok, I will make an issue for api change.

[alexey-ku77]

@kapoorutd Regarding https://github.com/wizbots/labtab/issues/95#issuecomment-403378322 As I understand - 400 responses caused OOM to happen. Does it correct?

[alexey-ku77]

If so, can you give more details(I.e. the chain of events) of the issue? But please don't simplify anything. Hope this way it will be easier to explain the problem.

[kapoorutd]

@alexey-ku77 OOM will be solved on our end by compressing the video, It doesnt mean App has memory leak but maybe device has low memory..We can compress the video but that may impact the quality of video.

Also,400 bad request is because client and Server are not sync with categories and Components. Which API we need to call to get this info? Please share one example as right now we are using metadata for the same.

[alexey-ku77]

It doesnt mean App has memory leak but maybe device has low memory.

It is possible to record video directly to disk? Or record in chunks measured by free ram for concrete device. Or maybe add ram guard to restrict or limit recording by memory parameters?

We can compress the video but that may impact the quality of video.

I don't like that idea. Need to know what thinks @internetmosquito

@alexey-ku77 OOM will be solved on our end by compressing the video,

But what the mechanism of getting OOM caused by 400 bad request?

Which API we need to call to get this info? Please share one example as right now we are using metadata for the same.

The same that is used to get level and nuggets metadata. It will be extended to include categories.

For Example you can refer that Calibration is a nugget according to matadata response from api, but we are unable to find it in api doc and it is not listed in component list for creating a video project api

@internetmosquito The new api matadata response is matching with the createProject production api doc, that means this new changes may work for productions credential. As we don't have any production credential, please test and confirm.

@kapoorutd can this be considered as solved in respect to recent update on staging server?

@alexey-ku77 If you think its working well, please mark it as fixed .
