Comment (by Kamedo2): I am testing the combination of these options on N-76111-g8c9c8fd. {{{ ["-b:a 8k", "-b:a 80k", "-b:a 160k", "-b:a 320k", "-b:a 530k", "-q:a 0.1", "-q:a 2", "-q:a 320k"], ["-profile:a aac_ltp", "-profile:a aac_main -aac_pred 1 -aac_pns 0", "-profile:a aac_low -aac_pns 1", "-profile:a mpeg2_aac_low"], ["-ar 8000", "-ar 11025", "-ar 24000", "-ar 44100", "-ar 48000", "-ar 96000"], ["", "-cutoff 15000", "-cutoff 22050"] }}} Test tracks are ffmpeg_aacvbr_pulse1.flac(12.12sec), ffmpeg_anmr_error.flac(2.32sec), ffmpeg_96k_error.flac(2.01sec). {{{-profile:a aac_ltp}}} encoding is currently slower than the realtime, about 0.9x on 44.1kHz. Is it the intended behavior? -- Ticket URL: <https://trac.ffmpeg.org/ticket/2686#comment:442> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
