Methods
concat(…varArgs) → {Uint8Array}
Concatenate buffers.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
varArgs |
BufferSource |
<repeatable> |
- Source:
Returns:
- Type
- Uint8Array
concatRange(arraynon-null, startopt, endopt) → {Uint8Array}
Concatenate a range of buffers from a flat array.
Avoids a subarray allocation compared to concat(...array.slice(s, e)).
Parameters:
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
array |
Array<!BufferSource> | |||
start |
number |
<optional> |
0 | Inclusive start index. |
end |
number |
<optional> |
Exclusive end index. |

Returns:
- Type
- Uint8Array
fromBase64(str) → {Uint8Array}
Convert a base64 string to a Uint8Array. Accepts either the standard
alphabet or the alternate "base64url" alphabet.
Parameters:
| Name | Type | Description |
|---|---|---|
str |
string |
- Source:
Returns:
- Type
- Uint8Array
fromHex(str) → {Uint8Array}
Convert a hex string to a Uint8Array.
Parameters:
| Name | Type | Description |
|---|---|---|
str |
string |
- Source:
Returns:
- Type
- Uint8Array
removeEmulationPreventionBytes(datanon-null) → {Uint8Array}
Removes H.264/H.265/H.266 emulation prevention bytes (the 0x03 that follows
a 0x00 0x00 sequence) from a NAL unit, i.e. converts EBSP to RBSP.
Builds the result in a single pass into a freshly allocated array. Using a
new array (rather than shifting bytes in place) keeps Chromium (VDA) happy
about NAL unit length conformance.
Parameters:
| Name | Type | Description |
|---|---|---|
data |
Uint8Array |
- Source:
Returns:
- Type
- Uint8Array
toBase64(data, paddingopt) → {string}
Convert a buffer to a base64 string. The output will always use the
alternate encoding/alphabet also known as "base64url".
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
data |
BufferSource | ||
padding |
boolean |
<optional> |
If true, pad the output with equals signs. Defaults to true. |

Returns:
- Type
- string
toHex(data) → {string}
Convert a buffer to a hex string.
Parameters:
| Name | Type | Description |
|---|---|---|
data |
BufferSource |
- Source:
Returns:
- Type
- string
toStandardBase64(data) → {string}
Convert a buffer to a base64 string. The output will be standard
alphabet as opposed to base64url safe alphabet.
Parameters:
| Name | Type | Description |
|---|---|---|
data |

Returns:
- Type
- string
