public static class AVCodecContext.Get_encode_buffer_AVCodecContext_AVPacket_int
extends FunctionPointer

This callback is called at the beginning of each packet to get a data buffer for it. The following field will be set in the packet before this callback is called: - size This callback must use the above value to calculate the required buffer size, which must padded by at least AV_INPUT_BUFFER_PADDING_SIZE bytes. In some specific cases, the encoder may not use the entire buffer allocated by this callback. This will be reflected in the size value in the packet once returned by avcodec_receive_packet(). This callback must fill the following fields in the packet: - data: alignment requirements for AVPacket apply, if any. Some architectures and encoders may benefit from having aligned data. - buf: must contain a pointer to an AVBufferRef structure. The packet's data pointer must be contained in it. See: av_buffer_create(), av_buffer_alloc(), and av_buffer_ref(). If AV_CODEC_CAP_DR1 is not set then get_encode_buffer() must call avcodec_default_get_encode_buffer() instead of providing a buffer allocated by some other means. The flags field may contain a combination of AV_GET_ENCODE_BUFFER_FLAG_ flags. They may be used for example to hint what use the buffer may get after being created. Implementations of this callback may ignore flags they don't understand. If AV_GET_ENCODE_BUFFER_FLAG_REF is set in flags then the packet may be reused (read and/or written to if it is writable) later by libavcodec. This callback must be thread-safe, as when frame threading is used, it may be called from multiple threads simultaneously.
