Codec context associated with this stream.

Allocated and freed by libavformat.

• decoding: The demuxer exports codec information stored in the headers here.
• encoding: The user sets codec information, the muxer writes it to the output. Mandatory fields as specified in AVCodecContext documentation must be set even if this AVCodecContext is not actually used for encoding.

This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented.

decoding: set by libavformat encoding: set by libavformat in avformat_write_header. The muxer may use the user-provided value of codec->time_base as a hint.

Decoding: pts of the first frame of the stream in presentation order, in stream time base.

Only set this if you are absolutely 100% sure that the value you set it to really is the pts of the first frame. This may be undefined (AV_NOPTS_VALUE).

Note

The ASF header does NOT contain a correct start_time the ASF demuxer must NOT set this.

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 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.
