| AVRational AVStream::time_base |
This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented.
decoding: set by libavformat encoding: May be set by the caller before avformat_write_header() to provide a hint to the muxer about the desired timebase. In avformat_write_header(), the muxer will overwrite this field with the timebase that will actually be used for the timestamps written into the file (which may or may not be related to the user-provided one, depending on the format).

| 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.
