But this assumption may not be universally true and we know some DSPs which do not contain the parsers so additional parameters are required to be passed. So add these parameters starting with FLAC decoder. The size of snd_codec_options is still 120 bytes after this change (due to this being a union) Co-developed-by: Srinivas Kandagatla Signed-off-by: Srinivas Kandagatla Signed-off-by: Vinod Koul --- include/uapi/sound/compress_params.h | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/include/uapi/sound/compress_params.h b/include/uapi/sound/compress_params.h index 3d4d6de66a17..9c96fb0e4d90 100644 --- a/include/uapi/sound/compress_params.h +++ b/include/uapi/sound/compress_params.h @@ -317,12 +317,22 @@ struct snd_enc_generic { __s32 reserved[15]; /* Can be used for SND_AUDIOCODEC_BESPOKE */ } __attribute__((packed, aligned(4))); +struct snd_dec_flac { + __u16 sample_size; + __u16 min_blk_size; + __u16 max_blk_size; + __u16 min_frame_size; + __u16 max_frame_size; + __u16 reserved; +} __attribute__((packed, aligned(4))); + union snd_codec_options { struct snd_enc_wma wma; struct snd_enc_vorbis vorbis; struct snd_enc_real real; struct snd_enc_flac flac; struct snd_enc_generic generic; + struct snd_dec_flac flac_d; } __attribute__((packed, aligned(4))); /** struct snd_codec_desc - description of codec capabilities
