int(* URLProtocol::url_open2)(URLContext *h, const char *url, int flags, AVDictionary **options)

This callback is to be used by protocols which open further nested protocols.

options are then to be passed to ffurl_open()/ffurl_connect() for those nested protocols.

int(* URLProtocol::url_read)(URLContext *h, unsigned char *buf, int size)

Read data from the protocol.

If data is immediately available (even less than size), EOF is reached or an error occurs (including EINTR), return immediately. Otherwise: In non-blocking mode, return AVERROR(EAGAIN) immediately. In blocking mode, wait for data/EOF/error with a short timeout (0.1s), and return AVERROR(EAGAIN) on timeout. Checking interrupt_callback, looping on EINTR and EAGAIN and until enough data has been read is left to the calling function; see retry_transfer_wrapper in avio.c.
