| StreamType::Enum. More... | |
Defines major audio and video stream types, and file formats (a.k.a.
containers).
| enum Enum |
| Enumerator | |
|---|---|
| Unknown | The stream type is not defined or is unknown. |
| BEGIN_AUDIO | This constant marks the start of audio elementary streams. It is not a valid stream type on its own. |
| LPCM | Audio encoded using pulse code modulation (PCM) with linear quantization. |
| ALAW_PCM | A-law PCM. |
| MULAW_PCM | Mu-law PCM. |
| VIDEO_DVD_PCM | LPCM with specific sample packing for Video-DVD. |
| AC3 | Dolby Digital Audio (a.k.a. AC-3). AC-3 is defined in ATSC A/52-A and A/52-B. |
| DTS | DTS (Digital Theater Systems) Coherent Acoustics codec, transportable through S/PDIF and used on DVDs, CD-DAs, LDs, and in wave files. |
| MPEG_Audio | MPEG-1 or MPEG-2 Audio, Layer I, II and III. |
| Vorbis | Vorbis Audio Codec. This is an open standard audio codec developed by the Xiph.Org Foundation. |
| AAC | Advanced Audio Coding. Initially it was defined in Part 7 of the MPEG-2 standard (known formally as ISO/IEC 13818-7) which is now obsolete. Currently it is defined in Part 3 of the MPEG-4 standard (known formally as ISO/IEC 14496-3). |
| AMRNB | Adaptive Multi-Rate audio (Narrow Band). |
| AMRWB | Adaptive Multi-Rate audio (Wide Band). |
| G726_ADPCM | G.726 ITU-T ADPCM |
| WMA | Microsoft Windows Media Audio. |
| WMA_Professional | Microsoft Windows Media Audio Professional. |
| WMA_Lossless | Microsoft Windows Media Audio Lossless. |
| END_AUDIO | This constant marks the end of audio elementary streams. It is not a valid stream type on its own. |
| BEGIN_VIDEO | This constant marks the start of video elementary streams. It is not a valid stream type on its own. |
| UncompressedVideo | Uncompressed video stream. |
| MPEG1_Video | MPEG-1 Video is defined in Part 2 of the MPEG-1 standard (known formally as ISO/IEC-11172-2). |
| MPEG2_Video | MPEG-2 Video is defined in Part 2 of the MPEG-2 standard (known formally as ISO/IEC 13818-2 and as ITU-T H.262). |
| MPEG4_Video | MPEG-4 Video is defined in Part 2 of the MPEG-4 standard (known formally as ISO/IEC 14496-2). |
| H261 | H.261 Video is defined in the ITU-T H.261 standard. |
| H263 | H.263 Video is defined in the ITU-T H.263 standard. |
| H264 | H.264 Video (also known as MPEG-4 AVC / Advanced Video Codec). Defined in Part 10 of the MPEG-4 standard (known formally as ISO/IEC 14496-10 and as ITU-T H.264). The actual bitstream format is determined by the stream sub-type: 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. H.264 Bitstream WITHOUT start codes H.264 bitstreams are stored in the MP4 container in this format. Instead of start codes, each NALU (Network Abstraction Layer Units) 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. |

| MJPEG | Motion JPEG (M-JPEG). |
| VC1 | VC-1 Video is defined in the SMPTE 421M-2006 standard. |

| Theora | Theora Video Codec. This is an open standard video codec developed by the Xiph.Org Foundation. |
| H265 | H.265 Video (also known as MPEG-H HEVC / High Efficiency Video Codec ) Defined in Part 2 of the MPEG-H standard (known formally as ISO/IEC 23008-2 and as ITU-T H.265). |
| HEVC | Alias. Same as StreamType::H265. |
