The actual bitstream format is determined by the stream sub-type: StreamSubType.AvcAnnexB 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. StreamSubType.Avc1 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. |

enum TranscoderError |
Defines Transcoder specific errors.
The Transcoder may also return errors like AVBlocksError, CodecError and others.
Enumerator | |
---|---|
NoChain |
= 1 The transcoder could not build a processing chain based on its inputs and outputs. Either the transcoder inputs and outputs are not configured properly or they are not compatible with each other. This error is returned by Transcoder.Open |
UndefinedSocketType |
= 2 The stream type of a MediaSocket is not defined. When a media socket describes a file, the stream type is deduced from the file extension. When a media socket describes a stream the stream type must be set explicitly. See StreamType. This error is returned by Transcoder.Open |
UnsupportedInterlacedConversion |
= 3 It is not possible to convert from progressive to interlaced video. Also it is not possible to switch interlace type from top-first to bottom-first or vice versa. This error is returned by Transcoder.Open |
NoCodec |
= 4 A required encoder or decoder is not available. |
UnsupportedVideoConversion |
= 5 It is not possible to convert from one uncompressed video format to another. See ColorFormat. |
BufferFull |
= 6 One of the input/output buffers is full and cannot accept more data. Cannot accept more input through Transcoder.Push. Call Transcoder.Pull to obtain output samples. |
