| AVPacketSideData* AVStream::side_data |
An array of side data that applies to the whole stream (i.e.
the container does not allow it to change between packets).
There may be no overlap between the side data in this array and side data in the packets. I.e. a given side data is either exported by the muxer (demuxing) / set by the caller (muxing) in this array, then it never appears in the packets, or the side data is exported / sent through the packets (always in the first packet where the value becomes known or changes), then it does not appear in this array.

| AVRational AVStream::r_frame_rate |
Real base framerate of the stream.
This is the lowest framerate with which all timestamps can be represented accurately (it is the least common multiple of all framerates in the stream). Note, this value is just a guess! For example, if the time base is 1/90000 and all frames have either approximately 3600 or 1800 timer ticks, then r_frame_rate will be 50/1.

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).

| int64_t AVStream::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.

Options for behavior, when a wrap is detected.

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.
