Writes Annex B formatted HEVC NAL units to the provided AVIOContext.
The NAL units are converted to an MP4-compatible format (start code prefixes are replaced by 4-byte size fields, as per ISO/IEC 14496-15).
If filter_ps is non-zero, any HEVC parameter sets found in the input will be discarded, and *ps_count will be set to the number of discarded PS NAL units.
pb | address of the AVIOContext where the data shall be written |
buf_in | address of the buffer holding the input data |
size | size (in bytes) of the input buffer |
filter_ps | whether to write parameter set NAL units to the output (0) or to discard them (non-zero) |
ps_count | address of the variable where the number of discarded parameter set NAL units shall be written, may be NULL |

Writes Annex B formatted HEVC NAL units to a data buffer.
The NAL units are converted to an MP4-compatible format (start code prefixes are replaced by 4-byte size fields, as per ISO/IEC 14496-15).
If filter_ps is non-zero, any HEVC parameter sets found in the input will be discarded, and *ps_count will be set to the number of discarded PS NAL units.
On success, *size holds the size (in bytes) of the output data buffer.
buf_in | address of the buffer holding the input data |
size | address of the variable holding the size (in bytes) of the input buffer (on input) and of the output buffer (on success) |
buf_out | on success, address of the variable holding the address of the output buffer |
filter_ps | whether to write parameter set NAL units to the output (0) or to discard them (non-zero) |

int | size, | ||
int | ps_array_completeness | ||
) |
Writes HEVC extradata (parameter sets, declarative SEI NAL units) to the provided AVIOContext.
If the extradata is Annex B format, it gets converted to hvcC format before writing.
pb | address of the AVIOContext where the hvcC shall be written |
data | address of the buffer holding the data needed to write the hvcC |
size | size (in bytes) of the data buffer |
ps_array_completeness | whether all parameter sets are in the hvcC (1) or there may be additional parameter sets in the bitstream (0) |
