currently, av_open_input_file() opens protocols without the
AVIO_FLAG_NONBLOCK flag.
I suggest that av_open_input_file() respect the AVFMT_FLAG_NONBLOCK flag by
calling avio_open() with AVIO_FLAG_NONBLOCK flag
whenever AVFMT_FLAG_NONBLOCK is set.
specifically (from libavformat/utils.c) :
if (!fmt || !(fmt->flags & AVFMT_NOFILE)) {
/* if no file needed do not try to open one */
+ int flags = AVIO_FLAG_READ | (fmt->flags & AVFMT_FLAG_NONBLOCK)?
AVIO_FLAG_NONBLOCK : 0;
- if ((err=avio_open(&pb, filename, AVIO_FLAG_READ)) < 0) {
+ if ((err=avio_open(&pb, filename, flags)) < 0) {
goto fail;
}
