Function Documentation

void ff_fetch_timestamp ( AVCodecParserContext * s,

int off,

int remove,

int fuzzy

)

Fetch timestamps for a specific byte within the current access unit.

Parameters: off byte position within the access unit

remove Found timestamps will be removed if set to 1, kept if set to 0.

fuzzy Only use found value if it is more informative than what we already have

int ff_combine_frame ( ParseContext * pc,

int next,

const uint8_t ** buf,

int * buf_size

)

Combine the (truncated) bitstream to a complete frame.

Returns: -1 if no complete frame could be created, AVERROR(ENOMEM) if there was a memory allocation error
