Function Documentation

int lqt_gavl_get_audio_format (  quicktime_t *  file, int  track, gavl_audio_format_t *  format )

Get the audio format for decoding. Parameters: file  A quicktime handle track  Track index (starting with 0) format  Returns the format. Returns: 1 on success, 0 if there is no such track.

int lqt_gavl_get_video_format (  quicktime_t *  file, int  track, gavl_video_format_t *  format )

Get the video format for decoding. Parameters: file  A quicktime handle track  Track index (starting with 0) format  Returns the format. Returns: 1 on success, 0 if there is no such track.

int lqt_gavl_decode_video (  quicktime_t *  file, int  track, gavl_video_frame_t *  frame, uint8_t **  rows )

Decode one video frame. Parameters: file  A quicktime handle track  Track index (starting with 0) frame  The frame rows  Rows (created with lqt_gavl_rows_create) Returns: 1 on success, 0 for EOF.

int lqt_gavl_decode_audio (  quicktime_t *  file, int  track, gavl_audio_frame_t *  frame, int  samples )

Decode one audio frame. Parameters: file  A quicktime handle track  Track index (starting with 0) frame  The frame samples  Number of samples to decode. Returns: The real number of decoded samples, 0 for EOF.

void lqt_gavl_seek (  quicktime_t *  file, gavl_time_t *  time )

Seek all tracks to a specific point. Parameters: file  A quicktime handle time  The time to seek to. This call sets the time argument to the real time, we have now. It might be changed if you seek between 2 video frames.

gavl_time_t lqt_gavl_duration (  quicktime_t *  file  )

Get the total duration. Parameters: file  A quicktime handle Returns: The duration Return the whole duration of the file as a gavl_time_t
