mobile app can't open video and html content

[Chris K]

hi all, 

I have compiled open edx android mobile app and have enabled the following setting on the mobile app: 

COURSE_VIDEOS_ENABLED = true 

Also in EDX studio, I have enabled the course setting as follow:

Mobile Course Available = true 

I can login using mobile app and view and enter the course. 

I have 2 problems right now:

1. Video is not displayed: I have put alternative url for video, with .webm and I confirm I can load the video if I type video URL directly on browser.

It will always display: The video isn't yet available on mobile

2. Multiple choices problem and html content can't be displayed. It always says "Page not found. The page that you were looking for was not found"

Anyone have a clue how to resolve these 2 issues? 

thanks,

Chris

Hi Chris,

1. Could you try with a .mp4 video?

2. Beside Oauth2 client, did you add an application (with the same client id) in Django admin -> Django OAuth toolkit (DOT) -> Applications ? If not, pls add one, because DOT token is required. Set Client type to public, and grant type to Resource owner password-based.

Hi Nguyen,

So I added 2 different URLs,  the mp4 for desktop and alternate url with webm. 

And there is one item under Django admin-> Django OAuth toolking -> Applications, which is Login Service for JWT Cookies.

I added another one with client id the same as OAuth client id for the mobile. Still the problem persists. 

Also there is this error in the mobile app console:

415 Unsupported Media Type

{"detail":"Unsupported media type \"application/merge-patch+json\" in request.

Hi Chris,

Could you upload the full .yaml configuration you use?

This is my working configuration with a mp4 video stored on amazon S3. I assume that you enable the video pipeline.

About the problem "problem not found", is there any other error in the logcat, at the time you click to see the multiple choice problems?

Hi Nguyen, 

Here is my config: 

COURSE_VIDEOS_ENABLED: true

USING_VIDEO_PIPELINE: false

if I set 

USING_VIDEO_PIPELINE: true 

video still not playable, but it can be downloaded. 

>>is there any other error in the logcat,

What do you mean by logcat? 

Thanks,

Chris

Hi Chris,

I mean the Logcat tab in the Android Studio. Without the full log, it is hard for us to see what's wrong. If your service is available online, you can censor sensitive information, such as sessionid or authentication token,..

About the video problem, The USING_VIDEO_PIPELINE should be set to false. could you put the debug points at getItem (CourseUnitPagerAdapter.java) and getPreferredVideoInfo (EncodedVideos.java), and see what happens?

Also,   "Video Available on Web Only" (in advanced setting when adding video) option should be set to false.

Hi Nguyen, 

Thank you for your input. 

Video Available on Web Only  already set to false.  It goes to fallback section 

if(isPreferredVideoInfo(fallback)){

return fallback;

}

Here is the logcat result

Hi Chris,

It seems strange to me... At this point, getItem (CourseUnitPagerAdapter.java) should return an instance of CourseUnitVideoFragment, and either the video either played or some other errors may appear, but not "This video isn’t yet available on mobile" anymore. Could you try to replace your video URL with an example from edX: https://s3.amazonaws.com/edx-course-videos/edx-edx101/EDXSPCPJSP13-G030300.mp4

If it still not work, maybe we need to wait for some more experienced people to help.

Hi Nguyen, I have changed the video to the S3 URL that you give me. Thank you. Still the same error displayed.

Does it have anything to do with this error in server (CMS module) :

Hi Chris. I also see this error in my Open edX instance. This is a warning for not having transcript, but in my case, the video is still played normally.
