opus_repacketizer_cat method

int opus_repacketizer_cat(
  1. Pointer<OpusRepacketizer> rp,
  2. Pointer<Uint8> data,
  3. int len
)

Add a packet to the current repacketizer state. This packet must match the configuration of any packets already submitted for repacketization since the last call to opus_repacketizer_init(). This means that it must have the same coding mode, audio bandwidth, frame size, and channel count. This can be checked in advance by examining the top 6 bits of the first byte of the packet, and ensuring they match the top 6 bits of the first byte of any previously submitted packet. The total duration of audio in the repacketizer state also must not exceed 120 ms, the maximum duration of a single packet, after adding this packet. * The contents of the current repacketizer state can be extracted into new packets using opus_repacketizer_out() or opus_repacketizer_out_range(). * In order to add a packet with a different configuration or to add more audio beyond 120 ms, you must clear the repacketizer state by calling opus_repacketizer_init(). If a packet is too large to add to the current repacketizer state, no part of it is added, even if it contains multiple frames, some of which might fit. If you wish to be able to add parts of such packets, you should first use another repacketizer to split the packet into pieces and add them individually. @see opus_repacketizer_out_range @see opus_repacketizer_out @see opus_repacketizer_init @param rp OpusRepacketizer*: The repacketizer state to which to add the packet. @paramin data const unsigned char*: The packet data. The application must ensure this pointer remains valid until the next call to opus_repacketizer_init() or opus_repacketizer_destroy(). @param len opus_int32: The number of bytes in the packet data. @returns An error code indicating whether or not the operation succeeded. @retval #OPUS_OK The packet's contents have been added to the repacketizer state. @retval #OPUS_INVALID_PACKET The packet did not have a valid TOC sequence, the packet's TOC sequence was not compatible with previously submitted packets (because the coding mode, audio bandwidth, frame size, or channel count did not match), or adding this packet would increase the total amount of audio stored in the repacketizer state to more than 120 ms.
