[Libav-user] What to replace ffurl_register_protocol with?

[Mahboud Zabetian]

To create a custom AVIOContext, I looked at:

AVIOContext *avio_alloc_context(

                  unsigned char *buffer,

                  int buffer_size,

                  int write_flag,

                  void *opaque,

                  int (*read_packet)(void *opaque, uint8_t *buf, int
buf_size),

                  int (*write_packet)(void *opaque, uint8_t *buf, int
buf_size),

                  int64_t (*seek)(void *opaque, int64_t offset, int
whence));

There are a bunch of parameters that I don't have access to such as buffer,
buffer_size.  Also I don't see any handlers for open and close.

Is there a better way to map ffurl_register_protocol parameters to a
context?


What I am trying to replace is:

cache1_protocol.name = CACHE1_PROTO;

cache1_protocol.url_open = cache1_open;

cache1_protocol.url_open2 = 0;

cache1_protocol.url_read = cache1_read;

cache1_protocol.url_write = cache1_write;

cache1_protocol.url_seek = cache1_seek;

cache1_protocol.url_close = cache1_close;

ffurl_register_protocol(&cache1_protocol);

Thanks!
