Struct mp4ra_rust::SampleEntryCode

pub struct SampleEntryCode(pub FourCC);

Codes identifying sample entries registered with ISO.

The handler() method will give you the code for the handler specified for this kind of sample entry, if a single handler is defined for it by MP4RA.

For example, to test if the sample entry is audio or video,

use mp4ra_rust::HandlerCode;

let sample_entry1 = SampleEntryCode::AVC1;
assert_eq!(sample_entry1.handler(), Some(HandlerCode::VIDE));

let sample_entry2 = SampleEntryCode::MP4A;
assert_eq!(sample_entry2.handler(), Some(HandlerCode::SOUN));

Implementations

impl SampleEntryCode

pub fn handler(&self) -> Option<HandlerCode>

Return the identifier of a handler for this type of sample entry, if a single handler type is defined. For those sample entry types where MP4RA notes there are ‘various’ handlers, this method will return None
