### Examples
Decode file using avi options
```
$ fq -d avi -o decode_samples=true . file
```
Decode value as avi
```
... | avi({decode_samples:true})
```
### Samples
AVI has many redundant ways to index samples so currently `.streams[].samples` will only include samples the most "modern" way used in the file. That is in order of stream super index, movi ix index then idx1 index.
### Extract samples for stream 1
```sh
$ fq '.streams[1].samples[] | tobytes' file.avi > stream01.mp3
```
### Show stream summary
```sh
$ fq -o decode_samples=false '[.chunks[0] | grep_by(.id=="LIST" and .type=="strl") | grep_by(.id=="strh") as {$type} | grep_by(.id=="strf") as {$format_tag, $compression} | {$type,$format_tag,$compression}]' *.avi
```

### Samples
AVI has many redundant ways to index samples so currently `.streams[].samples` will only include samples the most "modern" way used in the file. That is in order of stream super index, movi ix index then idx1 index.
### Extract samples for stream 1
```sh
$ fq '.streams[1].samples[] | tobytes' file.avi > stream01.mp3
```
### Show stream summary
```sh
$ fq -o decode_samples=false '[.chunks[0] | grep_by(.id=="LIST" and .type=="strl") | grep_by(.id=="strh") as {$type} | grep_by(.id=="strf") as {$format_tag, $compression} | {$type,$format_tag,$compression}]' *.avi
```

$ fq -h avi
avi: Audio Video Interleaved decoder
Options
=======
decode_samples=true Decode supported media samples
Decode examples
===============
# Decode file as avi
$ fq -d avi . file
# Decode value as avi
... | avi
# Decode file using avi options
$ fq -d avi -o decode_samples=true . file
# Decode value as avi
... | avi({decode_samples:true})
Samples
=======
AVI has many redundant ways to index samples so currently .streams[].samples will only include samples the most "modern" way used in the file. That is in order
of stream super index, movi ix index then idx1 index.
Extract samples for stream 1
============================
$ fq '.streams[1].samples[] | tobytes' file.avi > stream01.mp3
Show stream summary
===================
$ fq -o decode_samples=false '[.chunks[0] | grep_by(.id=="LIST" and .type=="strl") | grep_by(.id=="strh") as {$type} | grep_by(.id=="strf") as {$format_tag, $compression} | {$type,$format_tag,$compression}]' *.avi
