This fixes compatibility with e.g. pcm_a52 ALSA plugin which in
previous versions never set sample_fmt.

Code would allocate a new context but forget to assign it
to the pointer actually passed to avformat_open_input,
potentially causing a crash.
Even if it was initialized it would cause a memleak.
This caused crashes with e.g. mpd, see also

In these cases it can't be guessed from the operands (at least
not necessarily), and it seems some clang versions refuse to
compile it.
Fixes ticket #303.

ogg_save() copies streams[], but doesn't keep track of free()'ed
struct members. Thus, if in between a call to ogg_save() and
ogg_restore(), streams[].private was free()'ed, this would result
in a double free -> crash, which happened when e.g. playing small
chained ogg fragments.

In commit bebe72f4, the enum AV_PICTURE_TYPE_* was introduced. There are still places in the code where pict_type is used as an integer and there is a case where "pict_type = 0" with the explanation "let ffmpeg decide what to do". The new enum does not know a value of 0 and C++ will fail if compiling such programs anyway as it is refered as an int (and you cannot patch them properly).

This avoid a crash with in avfilter_merge_formats() in case one of the
filter formats list has multiple time the same entry.

Thanks to Mina Nagy Zaki for helping figuring out the issue.

When providing a custom AVIOContex for a AVFMT_NOFILE format
only print a warning instead of erroring out.
This allows the code to work with older MPlayer versions that
just always set pb out of laziness.

  A cmp instruction with two constants is invalid, thus "g" constraint is not correct but must be "rm" instead.
