- This solution is beta version of signageOS SMIL Player applet.
<smil>
<head>
<layout>
<root-layout width="1080" height="1920" backgroundColor="#FFFFFF" />
<region regionName="video" left="0" top="0" width="1080" height="1920" z-index="1" backgroundColor="#FFFFFF" mediaAlign="center" />
</layout>
</head>
<body>
<par>
Whole playlist goes here

</body>
</smil>- par and seq are fully supported
- smil timings ( wallclock, repeatCount ) are fully supported
- priorityClass and excl are fully supported
- conditional expressions are fully supported https://www.a-smil.org/index.php/Conditional_play
- region name has to be specified in one of these two ways
<region regionName="widget12"..../>
<region xml:id="widget12" .... />
- accepts only url to SMIL file ( form input at main page )
- url to SMIL file can be also passed as smilUrl variable via SoS timings
- all files ( audio, video.. ) must be stored on remote server
- it is possible to specify path to files in two ways, if file url is specified by relative path, absolute path is build by combining smil url and relative path
absolute
<video src="https://static.signageos.io/assets/video-test-1_e07fc21a7a72e3d33478243bd75d7743.mp4" />
relative
<video src="assets/landscape1.mp4" />
if smil path is https://static.signageos.io/testing.smil then absolute path for video will be https://static.signageos.io/assets/landscape1.mp4
- sequential and parallel play of audio, video, image and widget

We are using internal private NPM registry, so please copy the template .npmrc.template to .npmrc and adjust your local PC ~/.bashrc file as below (for unix systems, for Win add environment variables in windows This PC options).
echo 'export NPM_REGISTRY_URL="https://npm.signageos.io"' >> ~/.bashrc
echo 'export NPM_REGISTRY_HOST="npm.signageos.io"' >> ~/.bashrc
echo 'export NPM_AUTH_TOKEN="__PASTE_YOUR_SECRET_TOKEN__"' >> ~/.bashrc
cp .npmrc.template .npmrcnpm install
npm run build --production
// delete "sos" item in package.json
// login to signageOS
sos login
// upload the SMIL Player applet to signageOS
sos applet upload
// once the SMIL Player is uploaded, deploy to any supported device
