// If we want to change representations with different codec extra
// configuration in adaptive streaming scenarios, then we have to modify each
// packet data by inserting before video samples SPSes and PPSes in the
// following way:
// for each SPS:
// write length of SPS on lengthSizeMinusOne + 1 bytes in MSB format
// (BigEndian)
// write SPS NAL data (without any modifications)
// for each PPS: (do similar operation as for PPS)
// write length of PPS on lengthSizeMinusOne + 1 bytes in MSB format
// (BigEndian)
// write PPS NAL data (without any modifications)
// append video packet data
//
// For example:
// - VideoCodecConfig::extra_data_:
// 01 4D 40 20 FF E1 00 0C
// 67 4D 40 20 96 52 80 A0 0B 76 02 05
// 01 00 04 68 EF 38 80
// - length_size: 4
// - SPS count 1, SPS data: 67 4D 40 20 96 52 80 A0 0B 76 02 05
// - PPS count 1, PPS data: 68 EF 38 80
// - modified packet structure (in hex):
// 00 00 00 0C 67 4D 40 20 96 52 80 A0 0B 76 02 05 00 00 00 04 68 EF 38 80
// | | | |
// | | | |
// | | | | PPS NAL
// | | |
// | | | PPS length (4 bytes)
// | |
// | | SPS NAL
// |
// | SPS length (4 bytes)
