Extra steps to reproduce the problem?
N/A

What is the expected result?
All generated TS segments should contain a PCR field in the TS Adaptation Field where the 6 reserved bits (between the base and extension) are set to '1' not '0' (As per ISO 13818-1 section 2.1.46 "reserved" ... Unless otherwise specified, all reserved bits shall be set to '1') and the Adapation Field spec section 2.3.4.5, table 2-6)

What happens instead?
The bits are set to '0' instead of '1'

In src/media/formats/mp2t/ts_packet_writer_util.cc in WriteAdaptationField() function, the local variable "pcr_last_bit_reserved_and_pcr_extension" takes only the LSB of the base << 15 and does not also assert the reserved bits.

I believe the code line should read:
const uint16_t pcr_last_bit_reserved_and_pcr_extension =
((pcr_base & 1) << 15) | 0x7e00; // Assert reserved bits
