  • 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 ?
