Timedelta formats:
(a) Win64: 64 bits unsigned integer, number of 1/10 microsecond
- file format: Microsoft Word document (.doc), ASF video (.asf)
(b) 64 bits float, number of seconds
- file format: AMF metadata used in Flash video (.flv)
Other file formats use multiple numbers to store a duration:
[AVI video]
- 3 integers (32 bits unsigned): length, rate, scale
- seconds = length / (rate / scale)
- (seconds = length * scale / rate)
[WAV audio]
- 2 integers (32 bits unsigned): us_per_frame, total_frame
- seconds = total_frame * (1000000 / us_per_frame)
[Ogg Vorbis]
- 2 integers: sample_rate (32 bits unsigned), position (64 bits
unsigned)
- seconds = position / sample_rate |
