Convert sample frames for a track's current format to milliseconds.
Defined in <SDL3_mixer/SDL_mixer.h>
Sint64 MIX_TrackFramesToMS(MIX_Track *track, Sint64 frames);
MIX_Track * | track | the track to query. |
Sint64 | frames | the track-specific sample frames to convert to milliseconds. |
(Sint64) Returns Converted number of milliseconds, or -1 for errors/no input; call SDL_GetError() for details.
This calculates time based on the track's current input format, which can change when its input does, and also if that input changes formats mid-stream (for example, if decoding a file that is two MP3s concatenated together).
Sample frames are more precise than milliseconds, so out of necessity, this function will approximate by rounding down to the closest full millisecond.
On various errors (MIX_Init() was not called, the track is NULL), this returns -1. If the track has no input, this returns -1. If frames
is < 0, this returns -1.
It is safe to call this function from any thread.
This function is available since SDL_mixer 3.0.0.
