## Global format options
|
|
|
|
Currently the only global option is `force` and is used to ignore some format assertion errors. It can be used as a decode option or as a CLI `-o` option:
|
|
|
|
```
|
|
fq -d mp4 -o force=true file.mp4
|
|
fq -d raw 'mp4({force: true})' file.mp4
|
|
```
|
|
|
|

|
|

[fq -rn -L . 'include "formats"; formats_sections']: sh-start
|
|
|
|
### aac_frame
|
|
|
|
#### Options
|
|
|
|
|Name |Default|Description|
|
|
|- |- |-|
|
|
|`object_type`|1 |Audio object type|
|
|
|
|
#### Examples
|
|
|
|
Decode file using options
|
|
```
|
|
$ fq -d aac_frame -o object_type=1 file
|
|
```
|
|
|
|
Decode value as aac_frame
|
|
```
|
|
... | aac_frame({object_type: 1})
|
|
```
|
|
|
|
### asn1_ber
|
|
|
|
Supports decoding BER, CER and DER (X.690).
|
|
|
|
- Currently no extra validation is done for CER and DER.
|
|
- Does not support specifying a schema.
|
|
- Supports `torepr` but without schema all sequences and sets will be arrays.
|
|
|
|
#### Examples
|
|
|
|
`frompem` and `topem` can be used to work with PEM format
|
|
```
|
|
$ fq -d raw 'frompem | asn1_ber | d' cert.pem
|
|
```
|
|
|
|
Can be used to decode nested parts
|
|
```
|
|
$ fq -d asn1_ber '.constructed[1].value | asn1_ber' file.ber
|
|
```
|
|
|
|
If schema is known and not complicated it can be reproduced
|
|
```
|
|
$ fq -d asn1_ber 'torepr as $r | ["version", "modulus", "private_exponent", "private_exponen", "prime1", "prime2", "exponent1", "exponent2", "coefficient"] | with_entries({key: .value, value: $r[.key]})' pkcs1.der
|
|
```
|
|
|
|
Supports `torepr`
|
|
```
|
|
$ fq -d asn1_ber torepr file
|
|
```
|
|
|
|
Supports `torepr`
|
|
```
|
|
... | asn1_ber | torepr
|
|
```

|
|
|
|
|Name |Default|Description|
|

Decode value as avc_au
|
|
```
|
|
... | avc_au({length_size: 4})

|
```
|
|
|
|
### avro_ocf
|
|
|
|
Supports reading Avro Object Container Format (OCF) files based on the 1.11.0 specification.
|
|
|
|
Capable of handling null, deflate, and snappy codecs for data compression.
|
|
|
|
Limitations:
|
|
- Schema does not support self-referential types, only built-in types.
|
|
- Decimal logical types are not supported for decoding, will just be treated as their primitive type
