## Installation 

### Pip

```bash

$ pip install plot-av

```

### Conda

```bash

$ conda install plot-av -c conda-forge

```

## Usage

```bash

# basic use

$ plot-av -i test.mp4

# help 

$ plot-av -h

usage: plot-av [-h] -i INPUT [-vn | -an | -map STREAMS_SELECTION] [--dpi DPI] [--plots PLOTS] [--interval INTERVAL] [--log LOGLEVEL]

plot audio/video streams.

options:

  -h, --help            show this help message and exit

  -i INPUT              input file url (default: None)

  -vn                   disable video stream (default: False)

  -an                   disable audio stream (default: False)

  -map STREAMS_SELECTION

                        manually select streams, pattern 'input_index:stream_type:stream_index', e.g. '0:v:0', '0:a:0' (default: None)

  --dpi DPI             resolution of the figure. If not provided, defaults to 100 by matplotlib. (default: None)

  --plots PLOTS         subplots to show, seperate by ','. options: dts,pts,size,bitrate,fps,avsync,dts_delta,duration (default: dts,pts,size,bitrate,fps,avsync,dts_delta,duration)

  --interval INTERVAL   calculation interval in seconds for statistics metrics, such as bitrate, fps, etc. (default: 1.0)

  --log LOGLEVEL        log level (default: None)

```

### More examples

- Draw your interested subplots only

```bash

$ plot-av -i test.mp4 --plots dts,pts

```

- Draw video or audio only 

```bash

# disable video

$ plot-av -i test.mp4 -vn

# disable audio

$ plot-av -i test.mp4 -an

```

- Manually select streams from mutiple inputs

```bash

$ plot-av -i test1.mp4 -i test2.mp4 -map 0:v:0 -map 1:a:0 

```
