  • Encode PCM to MPEG-2 AAC with FFmpeg APIs

    13 août 2019, par Tank2006

    My environment is "ffmpeg version 3.4.6-0ubuntu0.18.04.1"

    I wrote a program to encode audio data into MPEG-2 AAC with reference to an official example.

    First, I simply changed the encoder value(and the full source code I wrote is here).

    if (!(output_codec = avcodec_find_encoder(AV_CODEC_ID_AAC))) {

    But FFmpeg S/PDIF encoder(spdifenc.c) returns an error “Wrong AAC file format”.

    I use avctx->profile = FF_PROFILE_MPEG2_AAC_LOW(FF_PROFILE_MPEG2_AAC_HE); but it takes no effects.

    Considering the possibility that the official binary was not compiled with the "CONFIG_ADTS_HEADER" C flag, I ran the following code directly as this :

    buf = output_packet.data;
    int err = init_get_bits8(&gb, buf, 7);
    if (get_bits(gbc, 12) != 0xfff) return AAC_AC3_PARSE_ERROR_SYNC;

    This didn’t find ADTS header "0xFFF", therefore, an encoder doesn’t seem to work as expected.

    How do I encode ffmpeg-2 aac audio with ffmpeg apis ?

  • How convert High bitrate mp3 to lower rate using ffmpeg in android

    23 mars 2018, par Android Team

    We want to convert 320kbps mp3 file to 128kbps mp3 so currently we are using below ffmpeg command but its not working.

    ffmpeg -i input.mp3 -codec:a libmp3lame -qscale:a 5 output.mp3

    Result :-the output bitrate same as input mp3.

    And we are following the FFmpeg Encoding guideline for that here is the link :- https://trac.ffmpeg.org/wiki/Encode/MP3

    so please suggest any solution.
