QUESTION
How do I configure my short domain to forward to my primary domain but persist the url path? For example...
example.org/ should redirect to example.com/
At the moment, the url path is being thrown out, so I'm seeing this... example.org/ redirects to example.com
Note: my primary domain is hosted and managed at AWS S3/CloudFont/Route-53.
The configuration for the distribution is as follows:
...ANSWER
Answered 2020-Aug-10 at 23:54To redirect from example.org/ to example.com/, simply use S3 routing rules.
- Create a bucket named

The error is as the title says. I've also been actively looking for other questions with similar issues, but I don't seem to be able to fix this one. Most people were using the v7 dependencies and were instructed to change it into androidx, but my dependencies are already up to date ( from what I can see). So what's the issue?

I am trying to import GestureDetectorCompat.class into Android Studio but doesn't work.
I tried adding import androidx.core.view.GestureDetectorCompat; and import android.support.v4.view.GestureDetectorCompat; above class definition of my activity but it shows Cannot resolve symbol 'GestureDetectorCompat' error.
Mousing over the GestureDetectorCompat in the code, I get options to add library to classpath, but clicking it does nothing and still cannot resolve the symbol.
I was trying to add it to ExoPlayer demo app PlayerActivity class.

QUESTION
I know that exoplayer has support for RTSP, but I need C++ code that works on players from lots of OSs, so I need to parse the RTP packet in C++ to NAL units before passing to exoplayer
I found a way to decode RTP packets using live555 and extract its NAL units. According to ExoPlayer's documentation:
Components common to all ExoPlayer implementations are:
A MediaSource that defines the media to be played, loads the media, and from which the loaded media can be read.
A MediaSource is injected via ExoPlayer.prepare at the start of playback. ...
So I need a custom MediaSource that can extract NAL units from my C++ code.
At the class reference for MediaSource we can see that there are already some MediaSources available. I though maybe SmoothStreaming MediaSource could work but there's no description of what it does exactly and in its constructor I have to provide an Uri or an SsManifest (what).
I can see that there exists a NAL unit utility in this library so maybe things are already half done
So how to build or use an already available MediaSource to read NAL units for ExoPlayer to play?
As an additinal, how would you pass the NAL units from C++ to Java? In the code I found it's simply storing them in a C++ buffer. Should I read this buffer in Java somehow?
UPDATE:
I've been researching how this library works. It all begins with a MediaSource which have objects like Extractor and DataSource. Seems that ExtractorMediaSource is a MediaSource where you can provide your own Extractor and DataSource.
As I understood, DataSource is a class that gets the raw bytes from any possible place, be it a file read or a network packet. Based on the available Extractor classes on the library like Mp4Extractor and Mp3Extractor, an Extractor is something that will interpret the data read from DataSource. The two main methods from the Extractor interface are:
ANSWER
Answered 2018-May-18 at 02:25You cannot play NAL units or raw H.264 stream with ExoPlayer.
The picture data must exist within a supported container/format.
It's not clear what your mysterious C++ code is doing, is it an NDK setup? What's its role in Android decoding? Are you saying you're unable to pass [from the C++ function] a data array into some Android function as function parameter? Is it something like this Java to C++ setup? It's not clear what your real problem is...
If you insist on Exoplayer, I can tell you that FLV is the one (on containers list) that might be the best option since it can be built in real-time (re-muxing). You first create an FLV header that holds SPS and PPS data then followed by keyframe (extracted H264 data from the first NAL). You'll have to get familiar with FLV bytes structure, but each frame header is around 13 bytes followed by NAL data, repeat for each frame until end. This woud be realtime transcoding.
As a second option, for Android, you could just use MediaCodec to decode the H264 as extracted from the NAL units. Here is a useful example source. Just use as:

you'd have to uninstall and reinstall API level 27 with the SDK manager, to get around that.
and probably consider getting a new drive - or at least check the integrity eg. with hddscan.
