| StreamSubType::Enum. More... | |
Defines audio and video stream subtypes.
| enum 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. |
| AAC_RAW | Raw AAC data format: AAC data is stored without headers. |
