## 🔥 Enjoy animating!

Streamjoy turns your images into animations using sensible defaults for fun, hassle-free creation.

It cuts down the boilerplate and time to work on animations, and it's simple to start with just a few lines of code.

Install it with just pip to start, blazingly fast!

```python
pip install streamjoy
```

Or, try out a basic web app version here:

https://huggingface.co/spaces/ahuang11/streamjoy

## 🛠️ Built-in features

- 🌐 Animate from URLs, files, and datasets
- 🎨 Render images with default or custom renderers
- 🎬 Provide context with a short intro splash
- ⏸ Add pauses at the beginning, end, or between frames
- ⚡ Execute read, render, and write in parallel
- 🔗 Connect multiple animations together

## 🚀 Quick start

### 🐤 Absolute basics

Stream from a list of images--local files work too!

```python
from streamjoy import stream

if __name__ == "__main__":
    URL_FMT = "https://www.cpc.ncep.noaa.gov/products/NMME/archive/2025090800/current/images/NMME_ensemble_tmpsfc_lead{i}.png"
    resources = [URL_FMT.format(i=i) for i in range(1, 8)]
    stream(resources, uri="nmme.gif")  # .gif, .mp4, and .html supported
```

![nmme](https://github.com/user-attachments/assets/ab9a3b5e-3b5c-4deb-b093-891adb936f0c)

### 💅 Polish up

Specify a few more keywords to:

1. add an intro title and subtitle
2. adjust the pauses
3. optimize the GIF thru pygifsicle

Note: This example no longer works because URL changed!

```python
from streamjoy import stream

if __name__ == "__main__":
    URL_FMT = "https://www.goes.noaa.gov/dimg/jma/fd/vis/{i}.gif"
    resources = [URL_FMT.format(i=i) for i in range(1, 11)]
    himawari_stream = stream(
        resources,
        uri="goes_custom.gif",
        intro_title="Himawari Visible",
        intro_subtitle="10 Hours Loop",
        intro_pause=1,
        ending_pause=1,
        optimize=True,
    )
```

### 👀 Preview inputs

If you'd like to preview the `repr` before writing, drop `uri`.

Note: This example no longer works because URL changed!

Output:
```yaml
<AnyStream>
---
Output:
  max_frames: 50
  fps: 10
  display: True
  scratch_dir: streamjoy_scratch
  in_memory: False
---
Intro:
  intro_title: Himawari Visible
  intro_subtitle: 10 Hours Loop
  intro_watermark: made with streamjoy
  intro_pause: 1
  intro_background: black
---
Client:
  batch_size: 10
  processes: True
  threads_per_worker: None
---
Resources: (10 frames to stream)
  https://www.goes.noaa.gov/dimg/jma/fd/vis/1.gif
  ...
  https://www.goes.noaa.gov/dimg/jma/fd/vis/10.gif
---
```

Then, when ready, call the `write` method to save the animation!

```python
himawari_stream.write()
```

### 🖇️ Connect streams

Connect multiple streams together to provide further context.

Note: This example no longer works because URL changed!

```python
from streamjoy import stream, connect

URL_FMTS = {
    "visible": "https://www.goes.noaa.gov/dimg/jma/fd/vis/{i}.gif",
    "infrared": "https://www.goes.noaa.gov/dimg/jma/fd/rbtop/{i}.gif",
}

if __name__ == "__main__":
    visible_stream = stream(
        [URL_FMTS["visible"].format(i=i) for i in range(1, 11)],
        intro_title="Himawari Visible",
        intro_subtitle="10 Hours Loop",
    )
    infrared_stream = stream(
        [URL_FMTS["infrared"].format(i=i) for i in range(1, 11)],
        intro_title="Himawari Infrared",
        intro_subtitle="10 Hours Loop",
    )
    connect([visible_stream, infrared_stream], uri="goes_connected.gif")
```

### 📷 Render datasets

You can also render images directly from datasets, either through a custom renderer or a built-in one, and they'll also run in parallel!

The following example requires xarray, cartopy, matplotlib, and netcdf4.

```bash
pip install xarray cartopy matplotlib netcdf4
```

```python
import numpy as np
import cartopy.crs as ccrs
import matplotlib.pyplot as plt
from streamjoy import stream, wrap_matplotlib

@wrap_matplotlib()
def plot(da, central_longitude, **plot_kwargs):
    time = da["time"].dt.strftime("%b %d %Y").values.item()
    projection = ccrs.Orthographic(central_longitude=central_longitude)
    subplot_kw = dict(projection=projection, facecolor="gray")
    fig, ax = plt.subplots(figsize=(6, 6), subplot_kw=subplot_kw)
    im = da.plot(ax=ax, transform=ccrs.PlateCarree(), add_colorbar=False, **plot_kwargs)
    ax.set_title(f"Sea Surface Temperature Anomaly\n{time}", loc="left", transform=ax.transAxes)
    ax.set_title("Source: NOAA OISST v2.1", loc="right", size=5, y=-0.01)
    ax.set_title("", loc="center")  # suppress default title
    plt.colorbar(im, ax=ax, label="°C", shrink=0.8)
    return fig

if __name__ == "__main__":
    url = (
      "https://www.ncei.noaa.gov/data/sea-surface-temperature-"
      "optimum-interpolation/v2.1/access/avhrr/201008/"
    )
    pattern = "oisst-avhrr-v02r01.*.nc"
    stream(
        url,
        uri="oisst.gif",
        pattern=pattern,  # GifStream.from_url kwargs
        max_files=30,
        renderer=plot,  # renderer related kwargs
        renderer_iterables=[np.linspace(-140, -150, 30)],  # iterables; central longitude per frame (30 frames)
        renderer_kwargs=dict(cmap="RdBu_r", vmin=-5, vmax=5),  # renderer kwargs
        # cmap="RdBu_r", # renderer_kwargs can also be propagated for convenience
        # vmin=-5,
        # vmax=5,
    )
```
