[Libav-user] ff_codec_wav_tags has duplicate tags

[坎]

Hi,
 
         When I tried to play a ogg file with audio formats as pcm_u8，it turned out to be pcm_s16le. By tracking the avformat_open_input, I got this:
 
st->codecpar->codec_id = ff_codec_get_id(ff_codec_wav_tags,...)
 
while, ff_codec_wav_tags as follows:
 
ff_codec_wav_tags[] = {
 
    { AV_CODEC_ID_PCM_S16LE,       0x0001 },
 
    /* must come after s16le in this list */
 
    { AV_CODEC_ID_PCM_U8,          0x0001 },
 
    { AV_CODEC_ID_PCM_S24LE,       0x0001 },
 
    { AV_CODEC_ID_PCM_S32LE,       0x0001 },
 
    { AV_CODEC_ID_PCM_S64LE,       0x0001 },
 
   When tags is 0x0001, AV_CODEC_ID_PCM_S16LE is always returned. Should they have different tags?
 
 
 
 
 
Best Regards.
 
Yeoman
