open_url_keepalive() unsets the options when it uses them, this includes the offsets for the Range: header. When using the HLS tag #EXT-X-BYTERANGE along with multiple files, the range options must be preserved after open_url_keepalive() returns EOF so that the new file can be opened. Failure to do this results in ignoring the #EXT-X-BYTERANGE tag and reading the wrong bytes of the file. To fix it, reset the options before calling io_open() following open_url_keepalive() reaching EOF Reviewed-by: Steven Liu <liuqi05@kuaishou.com>
