Extract a MPEG-4 AAC stream from MMT stream file

  1. Get the MMT information ``` DumpTS 03001.mmts –showinfo Layout of MMT: CID: 0X0(0): #0000 PLT (Package List Table): ——————————————————————————– #00000 MPT (MMT Package Table), Package_id: 0X1(1), packet_id: 0X9000(36864): #00000 Asset, asset_id: 0X8(8), asset_type: hev1(0X68657631): packet_id: 0X100(256) ++++++++++++++ Descriptor: Video component Descriptor +++++++++++++ file offset: 5 descriptor_tag: 0X8010 descriptor_length: 8 video_resolution: 6(0X6), height: 2160 video_aspect_ratio: 3(0X3), 16:9 without pan vector video_scan_flag: 1, progressive video_frame_rate: 8(0X8), 60/1.001 fps component_tag: 0(0X0) trans_characteristics: 3(0X3), Rec.

The total number of TLV packets: 135239. The number of IPv4 TLV packets: 0. The number of IPv6 TLV packets: 910. The number of Header Compressed IP packets: 116378. CID: 0x0000, packet_id: 0x9000, count: 299 - MPT CID: 0x0000, packet_id: 0x0000, count: 299 - PA Message CID: 0x0000, packet_id: 0x0100, count: 114,370 - HEVC Video Stream CID: 0x0000, packet_id: 0x0110, count: 1,406 - MPEG-4 AAC Audio Stream The number of Transmission Control Signal TLV packets: 0. The number of Null TLV packets: 17951. The number of other TLV packets: 0.

2. Find the MPEG-4 AAC CID and packet_id

CID is 0x0000, and packet_id is 0x0110

3. Export the MPEG-4 AAC audio stream

DumpTS 03001.mmts –CID=0 –pid=0x110 –output=03001_mmts_AAC.loas Total cost: 3052.383000 ms Total input TLV packets: 135239. Total MMT/TLV packets with the packet_id(0X110): 1407 Total MFUs in MMT/TLV packets with the packet_id(0X110): 0

4. Show the MPEG-4 AAC audio information

DumpTS 03001_mmts_AAC.loas –showinfo [MP4AAC] Successfully located the syncword in LOAS AudioMuxElement.
