+# Jello
+
+A WIP video client for jellyfin.
+
+(Planned) Features
+
+1. Integrate with jellyfin
+2. HDR video playback
+3. Audio Track selection
+4. Chapter selection
+
+Libraries and frameworks used for this
+1. iced -> primary gui toolkit
+2. gstreamer -> primary video + audio decoding library
+3. wgpu -> rendering the video from gstreamer in iced
+
+
+### HDR
+I'll try to document all my findings about HDR here.  
+I'm making this project to mainly learn about videos, color-spaces and gpu programming. And so very obviously I'm bound to make mistakes in either the code or the fundamental understanding of a concept. Please don't take anything in this text as absolute.
+
+```rust
+let window = ... // use winnit to get a window handle, check the example in this repo
+let instance = wgpu::Instance::default();
+let surface = instance.create_surface(window).unwrap();
+let adapter = instance
+    .request_adapter(&wgpu::RequestAdapterOptions {
+        power_preference: wgpu::PowerPreference::default(),
+        compatible_surface: Some(&surface),
+        force_fallback_adapter: false,
+    })
+    .await
+    .context("Failed to request wgpu adapter")?;
+let caps = surface.get_capabilities();
+println!("{:#?}", caps.formats);
+```
+
+This should print out all the texture formats that can be used by your current hardware  
+Among these the formats that support hdr (afaik) are  
+```
+wgpu::TextureFormat::Rgba16Float
+wgpu::TextureFormat::Rgba32Float
+wgpu::TextureFormat::Rgb10a2Unorm
+wgpu::TextureFormat::Rgb10a2Uint // (unsure)
+```
+
+My display supports Rgb10a2Unorm so I'll be going forward with that texture format.  
+
+`Rgb10a2Unorm` is still the same size as a `Rgba8Unorm` but data is in a different representation in each of them
+
+`Rgb10a2Unorm`: 
+R, G, B => 10 bits each (2^10 = 1024 [0..=1023])  
+A => 2 bits (2^2 = 4 [0..=3])  
+
+Whereas in a normal pixel
+`Rgba8Unorm`
+R, G, B, A => 8 bits each (2^8 = 256 [0..=255])
+
+
+For displaying videos the alpha components is not really used (I don't know of any) so we can use re-allocate 6 bits from the alpha channel and put them in the r,g and b components.  
+In the shader the components get uniformly normalized from [0..=1023] integer to [0..=1] in float so we can compute them properly
+
+Videos however are generally not stored in this format or any rgb format in general because it is not as efficient for (lossy) compression as YUV formats.
+
+Right now I don't want to deal with yuv formats so I'll use gstreamer caps to convert the video into `Rgba10a2` format
+
+
+## Pixel formats and Planes
+Dated: Sun Jan  4 09:09:16 AM IST 2026
+| value | count | quantile | percentage | frequency |

+| yuvj444p | 10 | 0.0027917364600781687 | 0.28% |  |
+
+For all of my media collection these are the pixel formats for all the videos
+
+### RGBA
+Pretty self evident   
+8 channels for each of R, G, B and A  
+Hopefully shouldn't be too hard to make a function or possibly a lut that takes data from rgba and maps it to Rgb10a2Unorm  
+
+```mermaid
+packet
+title RGBA  
++8: "R"
++8: "G"
++8: "B"
++8: "A"
+```
+
+
+### YUV
+[All YUV formats](https://learn.microsoft.com/en-us/windows/win32/medfound/recommended-8-bit-yuv-formats-for-video-rendering#surface-definitions)  
+[10 and 16 bit yuv formats](https://learn.microsoft.com/en-us/windows/win32/medfound/10-bit-and-16-bit-yuv-video-formats)
+
+Y -> Luminance
+U,V -> Chrominance
+
+p -> Planar
+sp -> semi planar
+
+j -> full range 
+
+planar formats have each of the channels in a contiguous array one after another
+in semi-planar formats the y channel is seperate and uv channels are interleaved
