* avio_open2() or a custom one.
* - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must
* be created with the avformat_new_stream() function. The caller should fill
- * the @ref AVStream.codec "stream codec context" information, such as the
- * codec @ref AVCodecContext.codec_type "type", @ref AVCodecContext.codec_id
+ * the @ref AVStream.codecpar "stream codec parameters" information, such as the
+ * codec @ref AVCodecParameters.codec_type "type", @ref AVCodecParameters.codec_id
* "id" and other parameters (e.g. width / height, the pixel or sample format,
* etc.) as known. The @ref AVStream.time_base "stream timebase" should
* be set to the timebase that the caller desires to use for this stream (note
* that the timebase actually used by the muxer can be different, as will be
* described later).
* - It is advised to manually initialize only the relevant fields in
- * AVCodecContext, rather than using @ref avcodec_copy_context() during
+ * AVCodecParameters, rather than using @ref avcodec_parameters_copy() during
* remuxing: there is no guarantee that the codec context values remain valid
* for both input and output format contexts.
* - The caller may fill in additional information, such as @ref
* increasing dts. Callers doing their own interleaving should call
* av_write_frame() instead of this function.
*
+ * Using this function instead of av_write_frame() can give muxers advance
+ * knowledge of future packets, improving e.g. the behaviour of the mp4
+ * muxer for VFR content in fragmenting mode.
+ *
* @param s media file handle
* @param pkt The packet containing the data to be written.
