119c61a30f RM audio stream version should be 16-bit followed by header size or reserved
word, so treat it this way instead of extracting different parts from 32-bit
value.

461ef74116 Make RM demuxer look more like proper demuxer by introducing codec tags

cbb5da57cd When resetting vst->pkt.data to NULL, also set vst->slices.
This avoids a crash when the next slice is not a start slice and thus
pkt->data is still NULL.
This probably only happens with broken or unsupported files like
http://samples.mplayerhq.hu/real/multirate/JustaSpa1937_64kb.rm
that need further fixes, but keeping vst state consistent is still a good idea.

34bddc39b4 Don't use a pointer-to-flags/timestamp in ff_rm_parse_packet(); the function
used to return packet data, which might update the flags/timestamp to be
used for the next packet data returned by the demuxer. However, that was
separated out into a new function, and the flags/timestamp are thus never
updated within ff_rm_parse_packet() anymore, and thus do not need to be
a pointer.

7a160bca83 Fix index generation in the way that it was supposed to be used. See the
discussion in the ML thread "[PATCH] rmdec.c: merge old/new packet reading
code".

Over time, this code broke somewhat, e.g. seq was never actually written
into (and was thus always 1, therefore the seq condition was always true),
whereas it was supposed to be set to the sequence number of the video slice
in case the video frame is divided over multiple RM packets (slices). The
problem of this is that packets other than those containing the beginning
of a video frame would be indexed as well.
Secondly, flags&2 is supposed to be true for video keyframes and for these
audio packets containing the start of a block. For some codecs (e.g. AAC),
that is every single packet, whereas for others (e.g. cook), that is the
packet containing the first of a series of scrambled packets that are to be
descrambled together. Indexing any of the following would lead to incomplete
and thus useless frames. Problem here is that flags would be reset to 2 to
indicate that the first packet is ready to be returned, and in addition if
no data was left to be returned (which is always true for the first packet),
then we wouldn't actually write the index entry anyway.
All in all, the idea was good and it probably worked at some point, but that
is long ago. This patch should at the very least make it likely for this code
to be executed again at the right times, i.e. the way it was originally
intended to be used.

b5b9ff2a1f Correctly skip complete INDX chunks, i.e. read the 32-bit header correctly
and if the size is broken (20 bytes, header-only), calculate the expected
size and skip the index entries anyway. See "[PATCH] rmdec.c: correctly
skip indexes" thread.

b8cc5a9fdf Prevent (negative) overflow of rm->remaining_len. This evaluation really only
has two possible outcomes: either len and rm->remaining_len are the same, in
which case we care about the outcome and it is zero, or rm->remaining_len is
currently not in use and we don't care about the outcome. In that case, len
is positive and rm->remaining_len is zero, which leads to a negative result.
This is confusing and could eventually lead to a sign-flip if we skip a lot
of packets (unlikely, but still). Therefore, just always set it to zero.
