| uint8_t* AVCodecParameters::extradata |
Extra binary data needed for initializing the decoder, codec-dependent.
Must be allocated with av_malloc() and will be freed by avcodec_parameters_free(). The allocated size of extradata must be at least extradata_size + AV_INPUT_BUFFER_PADDING_SIZE, with the padding bytes zeroed.

| int AVCodecParameters::bits_per_coded_sample |
The number of bits per sample in the codedwords.
This is basically the bitrate per sample. It is mandatory for a bunch of formats to actually decode them. It's the number of bits for one sample in the actual coded bitstream.
This could be for example 4 for ADPCM For PCM formats this matches bits_per_raw_sample Can be 0

| int AVCodecParameters::bits_per_raw_sample |
This is the number of valid bits in each output sample.
If the sample format has more bits, the least significant bits are additional padding bits, which are always 0. Use right shifts to reduce the sample to its actual size. For example, audio formats with 24 bit samples will have bits_per_raw_sample set to 24, and format set to AV_SAMPLE_FMT_S32. To get the original sample use "(int32_t)sample >> 8"."
For ADPCM this might be 12 or 16 or similar Can be 0
