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!
