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.

Examples:

demuxing_decoding.c, filtering_audio.c, filtering_video.c, muxing.c, qsvdec.c, remuxing.c, transcode_aac.c, and transcoding.c.

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).

Examples:

filtering_audio.c, filtering_video.c, muxing.c, remuxing.c, transcode_aac.c, and transcoding.c.

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.

• demuxing: Set by libavformat when the stream is created.
• muxing: May be set by the caller before avformat_write_header().

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).

Intended for use with formats such as mp3 with ad-hoc gapless audio support.

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.

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).

Number of internally decoded frames, used internally in libavformat, do not access its lifetime differs from info which is why it is not in that structure.

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.
