Inspired by a patch by Jakob van Bethlehem. But instead of doing
an empty POST first to trigger the WWW-Authenticate header (which
would succeed if no auth actually was required), add an Expect:
100-continue header, which is meant to be used exactly for
cases like this.
The header is added if doing a post, and the user has specified
authentication but we don't know the auth method yet.
Not all common HTTP servers support the Expect: 100-continue header,
though, so we only try to use it when it really is needed. The user
can request it to be added for other POST requests as well via
an option - which would allow the caller to know immediately that
the POST has failed (e.g. if no auth was provided but the server
required it, or if the target URL simply doesn't exist).
This is only done for write mode posts (e.g. posts without pre-set
post_data) - for posts with pre-set data, we can just redo the post
if it failed due to 401.
Signed-off-by: Martin Storsjö <martin@martin.st>
The default is to autodetect the auth method. This does require one
extra request (and also closing and reopening the http connection).
For some cases such as HTTP POST, the autodetection is not handled
properly (yet).
No option is added for digest, since this method requires getting
nonce parameters from the server first and can't be used straight
away like Basic.

This wasn't an issue prior to 58404738, when the whole RTMP packet

update_offset is also called from handle_metadata, where the
packet header sizes is already included in the size.
Previously this lead to flv_data/flv_size including 15 uninitialized
bytes at the end after each call to handle_metadata, making the
flv demuxer lose sync with the stream.
Also remove leftover copying in handle_metadata. This is a leftover
from the refactoring in 5840473. (Previously this final mempcy was
the one that copied all the packets at once, while this is done
within the loop right now.) After making sure flv_size is set to
the right size, this write was out of bounds.

timestamp: 00:05:28:361, filepos: 000025000 <???>
timestamp: 00:05:29:946, filepos: 000025800 Let's go see.
timestamp: 00:05:31:230, filepos: 000026000 I can't, man. I got Clayton.
Note the two "<???>": they are basically split subtitles (with the
previous one), which the dvdsub decoder is now supposed to reconstruct
with a previous commit. But also note that while the first chunk has
increasing timestamps,
timestamp: 00:05:02:018, filepos: 00001c800
timestamp: 00:05:02:035, filepos: 00001d000
...it's not the case of the second one (and this is not an exception in the
original file):
timestamp: 00:05:28:369, filepos: 000024800
timestamp: 00:05:28:361, filepos: 000025000
For the dvdsub decoder, they need to be "filepos'ed" ordered, but the
FFDemuxSubtitlesQueue is timestamps ordered, which is the reason of the
introduction of a sub sort method in the context, to allow giving
priority to the position, and then the timestamps. With that change, the
dvdsub decoder get fed with ordered packets.
Now the packet size estimation was also broken: the filepos differences
in the vobsub index defines the full data read between two subtitles
chunks, and it is necessary to take into account what is read by the
mpegps_read_pes_header() function since the length returned by that
function doesn't count the size of the data it reads. This is fixed with
the introduction of total_read, and {old,new}_pos. By doing this change,
we can drop the unreliable len16 heuristic and simplify the whole loop.
Note that mpegps_read_pes_header() often read more than one PES packet
(typically in one call it can read 0x1ba and 0x1be chunk along with the
relevant 0x1bd packet), which triggers the "total_read + pkt_size >
psize" check. This is an expected behaviour, which could be avoided by
having a more chunked version of mpegps_read_pes_header().
The latest change is the extraction of each stream into its own
subtitles queue. If we don't do this, the maximum size for a subtitle
chunk is broken, and the previous changes can not work. Having each
stream in a different queue requires some little adjustments in the
seek code of the demuxer.
This commit is only meaningful as a whole change and can not be easily
split. The FATE test changes because it uses the vobsub demuxer.
previously only codec_ids could be forced, which did not allow
forcing a specific implementation like libopenjpeg vs jpeg2000.
