Audio only. The number of "priming" samples (padding) inserted by the
encoder at the beginning of the audio. I.e. this number of leading
decoded samples must be discarded by the caller to get the original audio
without leading padding.
- decoding: unused
- encoding: Set by libavcodec. The timestamps on the output packets are
adjusted by the encoder so that they always refer to the
first sample of the data actually contained in the packet,
including any added padding. E.g. if the timebase is
1/samplerate and the timestamp of the first input sample is
0, the timestamp of the first output packet will be
-initial_padding.
