are non-obvious and probably need a large (about 1kB at least) probe buffer.

Try harder to avoid false positives for DV probe.
...
Require at least one signature match per provided 1MB of probe data,
and if there is only a single match, return at most MAX/4.
Fixes issue1382 but could/should probably still be improved.

Rewrite h261_probe().
...
New code can detect h261 startcodes even when the first is damaged or not at the
begin. It also passes probetest v2 & v3.

Make DTS probe more robust against false positives (as e.g. probetest shows).
...
In particular check that the detected markers clearly indicate a specific DTS
format (a wild mixture of e.g. little- and big-endian markers is unlikely to be
a valid DTS file) and ensure the markers appear with sufficient frequency.

Check the index validity more thoroughly for the c93 probe function.

In particular, check that length of the first index entries is not 0 since
that is interpreted "end of file" and makes no sense in the very first entries.

The new code should detect h263 even if the first startcode is damaged or
somewhere else than the first byte. It also passes probetest v2 as just

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.

Use all 32 bits of the timestamp when calculating flv duration.
...
At the moment, duration is mainly set from the metadata packet. If that is not
available, the fallback is checking the low 24 bits of the last packet. This is
not enough for files over 4,6 hours in length, so read all 32 bits instead.
