So the “recommended” FFmpeg version would still have to be built with an explicit liblame dynamic library file if that were to be used instead of LAME.A missing Lame_enc.dll file error usually occurs when working with Audacity. If using “libmp3lame-0.dll” from older FFmpeg, Audacity still complains about 05:03:42: Error: Couldn't find symbol 'beWriteInfoTag' in a dynamic library (error 127: the specified procedure could not be found.)Ġ5:03:42: Error: Couldn't find symbol 'beVersion' in a dynamic library (error 127: the specified procedure could not be found.)Ġ5:03:42: LAME library successfully loadedīut those are regarded as “optional” symbols and LAME loads OK.

In my case, despite selecting and opening the av* DLL, that DLL was producing all these missing symbol errors: 04:54:33: Error: Couldn't find symbol 'lame_init' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'get_lame_version' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_init_params' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_encode_buffer' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_encode_buffer_interleaved' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_encode_flush' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_close' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_in_samplerate' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_out_samplerate' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_num_channels' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_quality' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_brate' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_VBR' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_VBR_q' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_VBR_min_bitrate_kbps' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_mode' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_preset' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_error_protection' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_disable_reservoir' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_padding_type' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_set_bWriteVbrTag' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_get_lametag_frame' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'lame_mp3_tags_fid' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'beWriteInfoTag' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Error: Couldn't find symbol 'beVersion' in a dynamic library (error 127: the specified procedure could not be found.)Ġ4:54:33: Failed to find a required symbol in the LAME library.Īnd then using instead the correct LAME version from which I had installed into C:Program Files(x86). It seems you can use either the avcodec, avformat or avutil DLL file from FFmpeg to export MP3.
