◆ start_skip_samples

int64_t AVStreamInternal::start_skip_samples

If not 0, the number of samples that should be skipped from the start of the stream (the samples are removed from packets with pts==0, which also assumes negative timestamps do not happen).

◆ first_discard_sample

int64_t AVStreamInternal::first_discard_sample

If not 0, the first audio sample that should be discarded from the stream.

This is broken by design (needs global sample count), but can't be avoided for broken by design formats such as mp3 with ad-hoc gapless audio support.

◆ last_discard_sample

int64_t AVStreamInternal::last_discard_sample

The sample after last sample that is intended to be discarded after first_discard_sample.

Works on frame boundaries only. Used to prevent early EOF if the gapless info is broken (considered concatenated mp3s).

◆ pts_wrap_behavior

int AVStreamInternal::pts_wrap_behavior

Options for behavior, when a wrap is detected.

Defined by AV_PTS_WRAP_ values.

If correction is enabled, there are two possibilities: If the first time stamp is near the wrap point, the wrap offset will be subtracted, which will create negative time stamps. Otherwise the offset will be added.
