enum Enum

StreamSubType::Enum.

Enumerator
Unknown	The stream subtype is unknown.
None	No stream subtype is defined.
AAC_ADTS	Audio Data Transport Stream: AAC data in frames, similar to mp3. Somewhat compliant. Defined in Part 7 of the MPEG-2 standard (known formally as ISO/IEC 13818-7).
AAC_ADIF	Audio Data Interchange Format: AAC data with a single header. Worst compliance. Defined in Part 7 of the MPEG-2 standard (known formally as ISO/IEC 13818-7).
AAC_MP4	AAC data packed in MPEG-4 container (MP4). Best compliance.
AVCC	H.264/AVC bitstream without start codes. This is how the bitstream is stored in a MPEG-4 container (MP4). Instead of start codes, each NALU is prefixed by a length field, which gives the length of the NALU in bytes. The size of the length field can vary, but is typically 1, 2, or 4 bytes. Defined in ISO 14496-15.
AVC1	Alias. Same as StreamSubType::AVCC.
MPEG_TS_BDAV	MPEG2 transport stream with valid packet time stamps.
MPEG_Audio_Layer1	MPEG-1 Audio Layer I is commonly abbreviated to MP1. MPEG-1 Layer I is defined in ISO/IEC 11172-3. MPEG-2 Layer I is defined in the MPEG-2 Part 3 standard (known formally as ISO/IEC 13818-3).
MPEG_Audio_Layer2	MPEG-1 Audio Layer II is commonly abbreviated to MP2. MP2 is a dominant standard for audio broadcasting. MPEG-1 Layer II is defined in ISO/IEC 11172-3. MPEG-2 Layer II is defined in the MPEG-2 Part 3 standard (known formally as ISO/IEC 13818-3).
MPEG_Audio_Layer3	MPEG-1 Audio Layer III is commonly abbreviated to MP3. MPEG-1 Layer III is defined in ISO/IEC 11172-3. MPEG-2 Layer III is defined in the MPEG-2 Part 3 standard (known formally as ISO/IEC 13818-3).
G726_PACKED_RFC3551	G.726 stream packed according to RFC 3551. This type of packetization is used in RTP.
G726_PACKED_AAL2	G.726 stream packed according to ITU-T I.366.2 (AAL type 2). This type of packetization is used in Wave files.
MPEG1_System	MPEG-1 Program Stream as specified in MPEG-1 Part 1 (ISO/IEC 11172-1). This stream subtype can be used only with the MPEG_PS stream type.
MPEG2_System	MPEG-2 Program Stream as specified in MPEG-2 Part 1 (ISO/IEC 13818-1). This stream subtype can be used only with the MPEG_PS stream type.
AVC_Annex_B	H.264 bitstream with start codes. H.264 bitstreams are transmitted in this format over the air, or contained in MPEG-2 program or transport streams. The H.264 bitstream is formatted as described in Annex B of ITU-T Rec. H.264. According to this specification, the bitstream consists of a sequence of NALUs (Network Abstraction Layer Units). Each NALU is prefixed with a start code equal to 0x000001 or 0x00000001.
