Used by some encoders as upper bound for the length of headers.

TODO: Use proper codec-specific upper bounds.

Called by encoders to get the next frame for encoding.

Parameters

frame An empty frame to be filled with data.

Returns

0 if a new reference has been successfully written to frame AVERROR(EAGAIN) if no data is currently available AVERROR_EOF if end of stream has been reached, so no more data will be available

Get a buffer for a packet.

This is a wrapper around AVCodecContext.get_encode_buffer() and should be used instead calling get_encode_buffer() directly.

Check AVPacket size and allocate data.

Encoders of type FF_CODEC_CB_TYPE_ENCODE can use this as a convenience to obtain a big enough buffer for the encoded bitstream.

Parameters

avctx the AVCodecContext of the encoder

avpkt The AVPacket: on success, avpkt->data will point to a buffer of size at least size; the packet will not be refcounted. This packet must be initially blank.

size an upper bound of the size of the packet to encode

Returns

non negative on success, negative error code on failure
