Summary of the bug:
ffmpeg does not report upload failures when PUTting content to remote a
remote WebDAV server.
I'm trying to send HLS content to a remote server using ffmpeg. The server
requires Digest authentication. Credentials are provided in the URL, which
ffmpeg correctly extracts.
ffmpeg opens the connection and sends the request headers, including
Expect: 100 Continue, but obviously cannot include the Authorization
header at this point. The server responds 100 Continue (rather than eg a
401 Unauthorized), so ffmpeg assumes no auth is needed and continues to
send the body.
Once the request is complete, the server makes a final response with 401
Unauthorized but it seems that, once the connection is opened and 100 is
received, ffmpeg no longer cares for the rest of the response and never
checks again (it's just flushed when the connection is closed) so it
doesn't see that the request failed, and it doesn't retry with the
provided digest parameters.
I am aware that the server should probably respond to the Expect with 401
Unauthorized, but it also seems to me that ffmpeg ought to consume the
server's final response and see that the request ultimately failed for
some reason and report that back, instead of just assuming everything was
successful. Ideally ffmpeg would then retry with the relevant
authorization.
