I have a video file with audio.
ffprobe reports two different numbers: Sampling rate and Frame rate. I understand the 48kHz rate--there are 48,000 audio samples every second. What is the other number, and what is a "frame" in this context?
Audio ID : 2 Format : AAC ... Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF)
