```

How To Use
-----

### VideoReader  

```python
from video_toolkits import VideoReader, VideoReaderCV2

video_path = 'path to video'
reader = VideoReader(video_path)            # VideoReader - pyav, only support video file/stream
# reader = VideoReader(0)                   # webcam 0   VideoReaderCV2 support
for img in reader:
    pass
```


### VideoWriter 

```python
from video_toolkits import VideoWriter

img_seqs = []
out_path = '{VIDEO_NAME}.mp4'                     # currently support .mp4/.avi
succeed = VideoWriter.imgseq2video(img_seqs, out_path, fps=30)

# generate video on the fly
frame_size = (720, 1280)
video_writer = VideoWriter.video_writer_generator(out_path, frame_size)
video_writer.send(None)
for img in img_seqs:
    video_writer.send(img)
video_writer.close()
```

### Convert flv to mp4

```python
from video_toolkits import flv2mp4

input_vid = "{INPUT_FOLDER}/{VID_NAME}.flv"
output_folder = "{OUTPUT_FOLDER}"                 # if output_folder == '', will use {INPUT_FOLDER}
succeed = flv2mp4(input_vid, out_folder=output_folder) 
```

### Visualization

```python
from video_toolkits import display, draw_sklts, put_text, draw_bbox
from video_toolkits import draw_points, draw_lines
                                                                   
img = None
kpts = []                       # default (22, 4)
text = ""
bbox = []

display(img)                       # plot image with matplotlib.pyplot
img = draw_sklts(img, kpts, color=None, sklts=None)          # draw skeletons
img = put_text(img, text)                                    # put text
img = draw_bbox(img, bbox)

img = draw_points(img, [[0, 0], [1, 1]])
img = draw_lines(img, [[0, 0]], [[1, 1]], arrowed=False)
```

### load/dump json

```python
from video_toolkits import load_json, dump_json

json_obj = []
file_path = ""

annts = load_json(file_path)
dump_json(json_obj, file_path)
```
