Understanding ISO mp4 m4a Metadata - ios

I am unable to find a specification to understand the metadata from an m4a file.
This is not being copied across with AVAssetExportSession and I wanted to manually read and write this data to my exported file.
This is what I see in the debugger

looks like the name to an Atom (or block) in an MP4 container. I've seen those 5th through 12th bytes in a file that I made with Yamb and on the AtomicParsley page.

ESP8266 BearSSL MQTT Exception when connecting

I am trying to connect to HiveMQ MQTT Broker from my ESP8266, 2 months ago, this code works fine, but now, when I implement more features, the code run with a lot of Exceptions. Sometimes, Exception (28), I'm newbie in this fields and don't know the way to handle it, thanks for your helps.
RAM and Flash:
Exception:
Sometimes:
My Code:
void setup()

I expect to a successful and stable connection to MQTT Broker

Mtdoops cannot save the full panic log

I add a mtd partition (512kb) to save panic log by mtdoops on an arm based embedded devices(kernel v4.4).
I trigger the panic using "echo c > /proc/sysrq-trigger".
After the device reboot observe the kernel panic logs in the Oops partition by "strings", but the panic log seems to be truncated(limit in 2kb?).
How to change the limit of mtdoops?

Kafka stream window aggregation almost working

I need to aggregate some sensor data and I'm experimenting with windowed aggregation for a PoC/study project.
After researching here and there and a lot of attempts, I came up with the following code, which seems to be working.
I get in fact the peeks showing the expected results and I can also see the deserialisation/serialisation of the SensorData object happening through the stream.
And I can see the final result in the output topic.
Here is the problem though: after the first result is written in the output topic, the stream crashes and it crashes earlier or later depending on the length of the commitMs.
Any idea? Am I doing something wrong here?
I am using a landoop/fast-data-dev docker image to test this.
long commitMs = TBD;
Properties config = new Properties();
config.put(StreamsConfig.APPLICATION_ID_CONFIG, "sensor-data-stream-analyzer");

OS:NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.9.2
PRETTY_NAME="Alpine Linux v3.9"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://bugs.alpinelinux.org/"

I solved my problem and I'm going to share my solution here for whoever ends up having this same problem.
Initially the stack trace line "C [librocksdbjni6827723631295059350.so+0x3e13b5] rocksdb::ParseColumnFamilyOption(std::string const&, std::string const&, rocksdb::ColumnFamilyOptions*, bool)+0xc95" led me to think it was a musl-libc vs glibc related issue as mentioned in the following two issue links:
https://github.com/facebook/rocksdb/issues/3848
https://github.com/facebook/rocksdb/pull/3143
In fact I use a landoop/fast-data-dev:latest docker image, which is Alpine based. But a quick look at the landoop/fast-data-dev, shows that the author dealt with the glibc:
https://github.com/Landoop/fast-data-dev/blob/master/Dockerfile
# glibc : alpine linux has an embedded libc which misses some functions that are
# needed by some apps (e.g jvm's rocksdb jni — HDFS connector, Lenses, etc),
# so we add glibc to make them work. Also now we can add en_US.UTF-8 locale.
# https://github.com/sgerrand/alpine-pkg-glibc
The crash went away by simply replacing the kafka-stream dependency in my pom.xml from
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-streams</artifactId>
<version>2.0.1</version>
</dependency>
to
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-streams</artifactId>
<version>2.2.0</version>
</dependency>

Using range on AnyObject value

I'm working on a bluetooth project at the moment and after getting the value of the kCBAdvDataManufacturerData:
var data = advertisementData.value(forKey: "kCBAdvDataManufacturerData")
The values are hex values:
<00133377 08d704de ff03c200 00000000 00000000 00000000 00000000 00337701 416e746f 6e206465 20426f64 65000000 00000000 00000000>
what I know so far is that the value of kCBAdvDataManufacturerDatakey is an AnyObject
From the above value I need this:
00133377 08d704de ff03c200 00000000 00000000 00000000 00000000 00337701 416e746f 6e206465 20426f64 65000000 00000000 00000000
How can I get this value without converting it to a String? In other word is there a way to use something like Range on a AnyObject value without converting it to a String?

Unexpected rowpitch from WIC texture to DX11 texture

I am confused as to why I am getting 128 bytes for scan-lines/rowpitch rather than the 8 I am specifying. The BMP in question being loaded is 4 pixels, red top left, green top right, blue bottom left, yellow bottom right.
Code is as follows:
ID3D11Resource *g_pOverlay_Staging = nullptr;
IWICImagingFactory* WICFactory = nullptr;
IWICBitmapDecoder * WICBitmapDecoder = nullptr;
IWICBitmapFrameDecode * WICBitmapFrame = nullptr;
WICPixelFormatGUID pixelFormat;
HR(CoCreateInstance(CLSID_WICImagingFactory, nullptr, CLSCTX_INPROC_SERVER, __uuidof(IWICImagingFactory), (LPVOID*)&WICFactory));
HR(WICFactory->CreateDecoderFromFilename(L"province_map.bmp", nullptr, GENERIC_READ, WICDecodeMetadataCacheOnDemand, &WICBitmapDecoder));
HR(WICBitmapDecoder->GetFrame(0,&WICBitmapFrame));
HR(WICBitmapFrame->GetPixelFormat(&pixelFormat));
DXGI_FORMAT format;
if (pixelFormat == GUID_WICPixelFormat24bppBGR){
std::wostringstream outs2;
outs2 << "pixelformat = GUID_WICPixelFormat24bppBGR" << std::endl;
OutputDebugString(outs2.str().c_str());
format = DXGI_FORMAT_R8G8B8A8_UNORM;
}
IWICFormatConverter * FC = nullptr;
WICFactory->CreateFormatConverter(&FC);
HR(FC->Initialize(WICBitmapFrame, GUID_WICPixelFormat32bppRGBA, WICBitmapDitherTypeErrorDiffusion, 0, 0, WICBitmapPaletteTypeCustom));
std::unique_ptr<uint8_t[]> temp(new uint8_t[16]);
HR(FC->CopyPixels(0, 8, 16, temp.get()));
D3D11_TEXTURE2D_DESC desc;
desc.Width = 2;
desc.Height = 2;
desc.MipLevels = 1;
desc.ArraySize = 1;
desc.Format = format;
desc.SampleDesc.Count = 1;
desc.SampleDesc.Quality = 0;
desc.Usage = D3D11_USAGE_STAGING;
desc.BindFlags = 0;
desc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE | D3D11_CPU_ACCESS_READ;
desc.MiscFlags = 0;
D3D11_SUBRESOURCE_DATA initData;
initData.pSysMem = temp.get();
initData.SysMemPitch = 8;
initData.SysMemSlicePitch = 16;
ID3D11Texture2D* tex = nullptr;
HR(d3d11DeviceInterface->CreateTexture2D(&desc, &initData, &tex));
g_pOverlay_Staging = tex;
D3D11_MAPPED_SUBRESOURCE mapped_subresource;
HR(d3d11DeviceContextInterface->Map(g_pOverlay_Staging, 0, D3D11_MAP_READ_WRITE, 0, &mapped_subresource));
uint8_t * v = reinterpret_cast<uint8_t*>(mapped_subresource.pData);
unsigned int x = 0;
while (x < 256 ) {
std::bitset<8> one(v[x]);
std::bitset<8> two(v[x+1]);
std::bitset<8> three(v[x+2]);
std::bitset<8> four(v[x + 3]);
std::wostringstream outs1;
outs1 << "x[" << x << "] = " << one << " x[" << x + 1 << "] = " << two << " x[" << x + 2 << "] = " << three << " x[" << x + 3 << "] = " << four << std::endl;
OutputDebugString(outs1.str().c_str());
x += 4;
}
Output is:

This is expected. After you've uploaded texture memory to the GPU, if you Map it back for read, there's no guarantee that it will come back with the same pitch that you uploaded it as. This is because on upload, the driver re-lays out memory in a way that's optimal for rendering. When you bring it back to the CPU, the driver efficiently converts it back to linear format, usually in a way that reflects various properties of the texture cache or page size.
