Crate mp4parse_capi

C API for mp4parse module.

Parses ISO Base Media Format aka video/mp4 streams.

Examples

extern crate mp4parse_capi;
use std::io::Read;

extern fn buf_read(buf: *mut u8, size: usize, userdata: *mut std::os::raw::c_void) -> isize {
   let mut input: &mut std::fs::File = unsafe { &mut *(userdata as *mut _) };
   let mut buf = unsafe { std::slice::from_raw_parts_mut(buf, size) };
   match input.read(&mut buf) {
       Ok(n) => n as isize,
       Err(_) => -1,
   }
}
let capi_dir = std::env::var("CARGO_MANIFEST_DIR").unwrap();
let mut file = std::fs::File::open(capi_dir + "/../mp4parse/tests/minimal.mp4").unwrap();
let io = mp4parse_capi::Mp4parseIo {
    read: Some(buf_read),
    userdata: &mut file as *mut _ as *mut std::os::raw::c_void
};
let mut parser = std::ptr::null_mut();
unsafe {
    let rv = mp4parse_capi::mp4parse_new(&io, &mut parser);
    assert_eq!(rv, mp4parse_capi::Mp4parseStatus::Ok);
    assert!(!parser.is_null());
    mp4parse_capi::mp4parse_free(parser);
}

Functions

mp4parse_avif_free⚠	Free an Mp4parseAvifParser* allocated by mp4parse_avif_new().
mp4parse_avif_get_image⚠	Return a pointer to the primary item parsed by previous mp4parse_avif_new() call.
mp4parse_avif_new⚠	Allocate an Mp4parseAvifParser* to read from the supplied Mp4parseIo.
mp4parse_free⚠	Free an Mp4parseParser* allocated by mp4parse_new().
mp4parse_get_fragment_info⚠	Fill the supplied Mp4parseFragmentInfo with metadata from fragmented file.
mp4parse_get_indice_table⚠	Fill the supplied Mp4parseByteData with index information from track.
mp4parse_get_pssh_info⚠	Get 'pssh' system id and 'pssh' box content for eme playback.
mp4parse_get_track_audio_info⚠	Fill the supplied Mp4parseTrackAudioInfo with metadata for track.
mp4parse_get_track_count⚠	Return the number of tracks parsed by previous mp4parse_read() call.
mp4parse_get_track_info⚠	Fill the supplied Mp4parseTrackInfo with metadata for track.
mp4parse_get_track_video_info⚠	Fill the supplied Mp4parseTrackVideoInfo with metadata for track.
mp4parse_is_fragmented⚠	Determine if an mp4 file is fragmented. A fragmented file needs mvex table and contains no data in stts, stsc, and stco boxes.
mp4parse_new⚠	Allocate an Mp4parseParser* to read from the supplied Mp4parseIo and parse the content from the Mp4parseIo argument until EOF or error.
