This overload implements UNICODE options. The BASS_UNICODE flag will be added automatically, since all .Net strings are always unicode.
Namespace: Un4seen.Bass.AddOn.EncMp3
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.17.5
public static int BASS_Encode_MP3_StartFile( int handle, string options, BASSEncode flags, string filename )
Parameters
- handle
- Type: SystemInt32
The channel handle... a HSTREAM, HMUSIC, or HRECORD. - options
- Type: SystemString
Encoder options... =use defaults. The following LAME style options are supported:-b, -B, -v, -V, -q, -m, --abr, --preset, --alt-preset, -Y, --resample, -p, -t, --tt, --ta, --tl, --ty, --tc, --tn, --tg, --ti, --tv, --add-id3v2, --id3v1-only, --id3v2-only, --pad-id3v2, --pad-id3v2-size, --noreplaygain. Anything else that is included will be ignored. See the LAME documentation for details on the aforementioned options and defaults.
- flags
- Type: Un4seen.Bass.AddOn.EncBASSEncode
A combination of these flags (see BASSEncode):BASS_ENCODE_QUEUE Queue data to feed the encoder asynchronously. This prevents the data source (DSP system or BASS_Encode_Write call) getting blocked by the encoder, but if data is queud more quickly than the encoder can process it, that could result in lost data. BASS_ENCODE_LIMIT Limit the data rate to real-time speed, by introducing a delay when the rate is too high. With BASS 2.4.6 or above, this flag is ignored when the encoder is fed in a playback buffer update cycle (including BASS_Update(Int32) and BASS_ChannelUpdate(Int32, Int32) calls), to avoid possibly causing playback buffer underruns. Except for in those instances, this flag is applied automatically when the encoder is feeding a Shoutcast or Icecast server. BASS_ENCODE_CAST_NOLIMIT Don't limit the data rate (to real-time speed) when sending to a Shoutcast or Icecast server. BASS_ENCODE_PAUSE Start the encoder paused. BASS_ENCODE_AUTOFREE Automatically free the encoder when the source channel is freed. - filename
- Type: SystemString
Output filename... =no output file.
Return Value
Type: Int32The encoder handle is returned if the encoder is successfully started, else 0 is returned (use BASS_ErrorGetCode to get the error code).
BASS_Encode_StartUser(Int32, String, BASSEncode, ENCODERPROC, IntPtr) is used internally to apply the encoder to the source channel, so the remarks in its documentation also apply to this function.
Each tag should be in UTF-16 (as the BASS_UNICODE flag is used). Unicode tags can only be stored in ID3v2 tag blocks. An ID3v2 tags block will be added automatically when required by the tags; this can be changed in options.
MP3 encoding involves extensive floating-point operations, so it is not supported on platforms/architectures that do not have an FPU, eg. older ARM platforms/architectures.
ERROR CODE | Description |
---|---|
BASS_ERROR_HANDLE | handle is not valid. |
BASS_ERROR_FORMAT | The channel's sample format is not supported by the encoder. |
BASS_ERROR_ILLPARAM | options contains an invalid setting. |
BASS_ERROR_FILEOPEN | A '--ti' option file could not be opened. |
BASS_ERROR_FILEFORM | A '--ti' option file has an invalid format. It needs to be JPEG, PNG, or GIF. |
BASS_ERROR_MEM | There is insufficient memory. |
BASS_ERROR_NOTAVAIL | This function is not available on platforms/architectures without an FPU. |
BASS_ERROR_UNKNOWN | Some other mystery problem! |
