It does not make sense (DV is interleaved by design) and
it avoids a crash when the non-interleaved code tries to
use the priv_data of streams created by the DV demuxer.
The crash could be avoided differently, but then that stream
would still lack an index and would not play correctly in
non-interleaved mode.

This enables non interleaved AVI mode for example.
Players that are picky on strict interleaving can set this.
Patches to only switch to non intereaved AVI mode when the index is not strictly
correctly interleaved are welcome.

If there are no variants, the total bitrate of the single
stream isn't known, and exporting variant_bitrate = 0 does
look weird, since there really aren't any variants.

All file names should be in UTF-8 within libavformat.
This is handled by mapping the open() function to an internal one
in os_support.h for windows.
fopen() could be overridden in the same way, but if that would be
used from ffmpeg.c, it would add a dependency on an ff prefixed
internal lavf function.

This should hopefully fix roundup issue 2586.
This commit only implements it in the demuxer, not in the
protocol handler. If desired, some of the code could be
refactored to be shared by both implementations.

This can later be extended to support other AES bit sizes,
encryption, other crypto algorithms, reading the key from a URL, etc.
In order to use it, the key and initialization vector has to be
passed via AVOptions. Since such options can't be passed to
protocols from the command line, the protocol is currently
only for libavformat internal use.

In write_packet(), return AVERROR(EINVAL) rather than AVERROR(EIO) if
the provided output filename pattern is not valid. Indeed this has to
be considered a configuration error rather than an I/O error.
Allow a less confusing error report.
Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>
AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and
has a too much specific meaning, which is better explained through a
log message. Thus it can be replaced by AVERROR(EINVAL).
This breaks API.

The problem with url_exist() is that it tries to open a resource in
RDONLY mode. If the file is a FIFO and there is already a reading
client, the open() call will hang.
By using avio_check() with access mode of 0, the second reading
process will check if the file exists without attempting to open it,
thus avoiding the lock.
Fix issue #1663.
Signed-off-by: Anton Khirnov <anton@khirnov.net>
Make AVIO_FLAG_ access constants work as flags, and in particular fix
the behavior of functions (such as avio_check()) which expect them to
be flags rather than modes.
This breaks API.
