The reference for developers of streaming live TV and VOD Tizen .Net applications.

JuvoPlayer

Introduction

JuvoPlayer is a reference player application designed to be platform and component agnostic, leveraging dependence on device firmware updates (OTNs) and offering greater implementation flexibility. Source code is open and can be included in the software products under the MIT license conditions.

Please read the articles listed below before starting development:

• Dependencies
• Setup
• Launching
• Debugging
• Release notes

Concept

High level conceptual diagram. Dashed lined blocks represent external components/systems. Dotted blocks represent generalised elements. Dotted line surrounded blocks represent JuvoPlayer structures. Dark blue blocks are 3rd party libraries.

User Interfaces

Four grey blocks in the left upper corner represent UIs. UIs differ by underlying framework.

• JuvoPlayerXamarin - XamarinForms implementation. Portable to platforms supported by XamarinForms, i.e. Android, iOS, Windows, Tizen .Net
• JuvoReactNative - React Native Tizen .Net implementation. A fork of MS React Native .Net open source project. React Native Tizen .Net offers basic UI controls and bindings.
• JuvoOpenGLNative - NUI based application with OpenGL UI implemented using custom made C++ UI library. Offers excellent animation performance and UI design flexibility.
• SimplePlayer - Simplistic UI based on XamarinForms app template.

Core: Common Set of Libraries

User Interfaces are implemented as separate Smart TV applications containing common libraries (Core). Responsibilities of the blocks are self-explanatory. As an example, the 'DashDataProvider' class prepares all the data from requested MPEG DASH .mpd (manifest file) for playback.

'Player module' represents the JuvoPlayer/Player folder content. It feeds the Tizen TV platform player with extracted elementary stream packets.

'FFmpeg' - FFmpeg C libraries.

MPEG-DASH, HLS, RTP/RTSP and Progressive HTTP streaming protocols are supported. New streaming protocols can be added and distributed as a part of the JuvoPlayer core.

Secured Content

Premium VOD services use DRM secured content. Secured content playback is executed using Common Encryption Interface (CENC). JuvoPlayer's DRM module provides decryption and key management services. Decrypted content is stored inside TrustZone with no application access to decrypted data. Following DRMs are supported:

• PlayReady
• Widevine

juvoplayer's Issues

Application refers a forbidden assembly directly

When launching the UI Applications on a 2019 Samsung SmartTV, I'm getting the following errors:

[FAIL] SimplePlayer.Tizen.TV.dll refers a forbidden assembly directly - Xamarin.Forms.Core :(

[FAIL] JuvoPlayer.Xamarin.Tizen.TV.dll refers a forbidden assembly directly - Xamarin.Forms.Platform.Tizen :(

[FAIL] JuvoPlayerOpenGLNative.Tizen.TV.dll refers a forbidden assembly directly - JuvoPlayer :(

Launching the ReactNative one just shows a black screen.

Sofware Version: T-MSMDEUC-1315.4, B6912200/050204, BT-S

Unsupported container?

Player return -> Unsupported container but what mean container if i put h264 frame data to elementary stream?

Use hijacked FFImageLoading library

Hello,
Can we have an updated version of FFimageloading?
Because we have to update to use all the features like "DownsampleToViewSize",
with your version, we cannot use it.

I tried before to write, and with the latest version, and "DownsampleToViewSize" work fine, I haven't tried the rest of the features, but this one is important.

About security mechanism,
did you say that development can be disabled and once released (published) will it work on samsung televisions?
I can create a certificate with the partner level, but I don't know how to deactivate this mechanism

thank you.

Performance of JuvoPlayer OpenGL player

Hi,

I checked with JuvoPlayer OpenGL performance is quite good with live streaming.
But because .NET is not supported on older Samsung TV, I want to achieve same using NaclPlayer.

while investigating OpenGL player if i stop OpenGL rendering just after play starts. performance decreases significantly. That means player frames are also being rendered using openGL ? or just the controls ?
I want to know how does openGL rendering is connected with eglSurface of player window.
I think it internal sharing of EGLSurface between openGL and TVGLApplication class (from ElmSharp window).

Need this information to check feasibility of similar improvement on NaclPlayer.

Not able to install Xamarin JuvoPlayer with esplayer partner privilege

Hi,

I have compiled JuvoPlayer with Visual Studio for Tizen with setting up all dependencies.
But when try to install on Real device or emulator it gives me below error.
install failed[118, -14], reason: Signature error :

when I remove all partner privilege from manifest file. It allows to install.

I searched on internet and found that "http://developer.samsung.com/privilege/esplay"it is partner privilege. So created partner certificates (tried both Samsung and Tizen) but still it fails.

Anybody knows the reason here ? I am stuck at this.

Can JuvoPlayer play UDP/RTP on Samsung Tizen TV 2020?

Dear @pbsamsung ,
I'm developing a WebApp on TV Tizen. But it can't play UDP/RTP. When I see JuvoPlayer written by C#. I've seen your update readme. I see it can play RTSP.
But I have two link:
udp://@225.1.2.249:30120
rtp://225.1.1.240:30120

So do you give me your recommend?
Can JuvoPlayer can play UDP/RTP on TV Tizen 2020?

Thanks & Best regards

Signature Error while installing app on Emulator

Hello~

We got "Signature error" below while installing app on the emulator.
I was downloading any other sample applications on the same emulator so guessing there would be no certificate issue on my current setup.
To make test easy, unloaded Junoplayer.OpenGL/XamarinPlayer/ReactNative for now.

JuvoPlayer does supports udp multicast?

Question about JuvoPlayer

I would like to build an IPTV player app using JuvoPlayer. I want to ask you please is this player able to detect subtitles and closed caption (CC) in live streaming links (m3u8/ts)?
Also is it possible to play links such as (rtsp:// or rtmp://)?

I'm looking forward to get an answer as soon as possible
