More consistent with the original libmpcodecs code, and the name
"unsharpen" was confusing.

Also create a "dar" alias for the "a" variable, for avoiding possible

Replace sizeof((*avff)->formats)
with    sizeof(*(*avff)->formats)

as the size of the array element is given by the pointed element
rather than by its pointer.

In particular fix computation with the pending patch when
sizeof(int64_t) != sizeof(int64_t *).

Different sample formats are different sizes.

Makes the code less obfuscated and fixes encoding one video stream to
several outputs.

Also use avcodec_alloc_frame() instead of allocating AVFrame on stack.

Breaks me_threshold in avconv, as motion vectors aren't passed through
lavfi. They could be copied manually, but I don't think this misfeature
is useful enough to justify ugly hacks.

This declares dependencies to skip tests using libavfilter
when it is disabled.

iterator variable.

8-bit unsigned is the native sample format.

Adds an additional check before reading the next block header and avoids a
potential integer overflow when checking the metadata size against the
remaining buffer size.

Specifying the payload type is useful when the type number has
already been negotiated before creating the stream, for example
in SIP protocol.

Deprecate -v option, now only -loglevel is enough.

This way, all messages can be easily disabled with -loglevel.

Behavior change -- configuration is printed with AV_LOG_VERBOSE, so it's
not shown by default.

This way it can be applied to cmdutils too -- e.g. showing the banner
and printing startup messages.
