Support for iOS platform to use kvssink plugin

[sbelbin]

The GStreamer project supports Apple's iOS platform* such as iPhone and iPad devices whereas the AWS Kinesis Video streams producer SDK project (referred to as this SDK project) already supports Mac OS platform, but I haven't found any documentation/topic about building and deploying the AWS kvssink plugin for iOS platform.

The GStreamer provided package contains static libraries, without any dynamic libraries (.dylib) with several common GStreamer plugins built-in. The fact that GStreamer only provides static library becomes an issue that I'll explain later on.

For building this SDK project, I followed the guidelines along with option to build the GStreamer plugin (kvssink). This produces a dynamic library (libgstkvssink.dylib).

I use an iPad app to validate GStreamer in which I can provide a GStreamer pipeline using some of the common GStreamer plugins to ensure that GStreamer on iPad works.

When I include the libgstkvssink.dyilb into the iPad and when I put the kvssink directive into the pipeline, the app fails because it lacks dependencies such libgstreamer-1.0.0.dylib & libgstbase-1.0.0.dylib.

I'd anticipated this since the GStreamer provides an iOS package along with an XCode framework thats contains static libraries without dynamic libraries.

My questions for this discussion group:

• Has anyone faced this issue of using kvssink GStreamer plugin on iOS platform?
• If so how did your resolve it?

I'm reaching out to this group before exploring into other avenues. One of which is to incorporate the kvssink as a GStreamer's subproject is built into GStreamer as a static library. Thus GStreamer iOS package contains the kvssink as static libraries alongside the other common plugins of the other subprojects.

I've progressed on this matter so that it can be deployed and running on iOS devices on ARM64 (Apple M processors), see the recipe below.

At this point my test app on the iPad starts where it defines a pipeline in which the sink is to an AWS Kinesis video stream that is already created (which I've already verified on my MAC OSx). However, on the iPad it fails due to certificate issues see below:

kvssink stream-name=****************** storage-size=128 aws-region=****** access-key=**************** secret-key=********************************

2024-12-10 15:27:26 [0x16c93f000] WARN - curlCompleteSync(): [******************] curl perform failed for url https://kinesisvideo.*****.amazonaws.com/describeStream with result SSL peer certificate or SSH remote key was not OK:

I'm looking into possibly using the iot-certificateoptions to the kvssink plugin & provide the necessary certificates file.

However, this seems to me as heavy handed solution. I'd rather find another option.

Any suggestions?

Recipe to get AWS Video Stream AWS Video Stream GStreamer plugin build and deployed for iOS platforms

Build the AWS Video Stream GStreamer plugin as a static library libgstkvssink.a as well as all of its dependencies such as:

• libKinesisVideoProducer.a
• libcproducer.a
• libkvspic.a
• libkvspicUtils.a
• libkvsCommonCurl.a
• libcurl.a
• liblog4cplus.a

Adapt the XCode project(s) as to reference as to provide the library folder path(s) to those static libraries and directives for each static library.

After which, provide the following code to declare & register the kvssink plugin. This is usually done in the gst_ios_init.m file, see GStreamer's iOS examples.

...

#if defined(GST_IOS_PLUGIN_KVSSINK)
GST_PLUGIN_STATIC_DECLARE(kvssink);
#endif


void
gst_ios_init (void)
{
...
#if defined(GST_IOS_PLUGIN_KVSSINK)
    GST_PLUGIN_STATIC_REGISTER(kvssink);
#endif
...
}
