mxfdec: hybrid demuxing/seeking solution · f028d4d1

Janne Grunau authored Dec 08, 2011

This uses the old demuxing code for OP1a and separate demuxing code for OPAtom.
Timestamp output is added to the old demuxing code.

The seeking code is made to seek to the start of the desired EditUnit only,
from which the normal demuxing code takes over (if OP1a). This means we
do not use delta entries or slices, only StreamOffsets. OPAtom seeking
basically works like before.

This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other
words, we allow seeking before the start or past the end for D-10 too.

Based on several patches by Tomas Härdin <tomas.hardin@codemill.se> and
Reimar Döffinger <Reimar.Doeffinger@gmx.de>.

Changed av_calloc to av_mallocz, added overflow checks.

It is a really bad idea to assign a video codec id

mxfdec: Speed up metadata and index parsing. · 775d3b4a

Tomas Härdin authored Mar 14, 2011

Specifically, this means parsing as before until we run into essence.
At that point we seek to the footer and parse until EOF. After that we start
seeking backward to the previous partition and parse that until we run into
essence or the next partition. This procedure is repeated until we encounter
the last partition we parsed in the forward direction.

The end result of all this is that large essence containers are not needlessly
parsed. This speeds up parsing large files a lot.

avserver: fix build after the next bump. · b263bf66

Anton Khirnov authored Jan 12, 2012

Now that 0.8 is out we can reapply this commit. It breaks shared
avserver builds due to avserver using internal libavformat symbols,
which are now hidden, so this commit also disables avserver with
--enable-shared.

rtsp: Use a random offset for trying to open UDP ports for RTP · 58f09785

Dmitry Volyntsev authored Jan 18, 2012

This avoids (for all practical cases) the issue of reusing
the same UDP port as for an earlier connection. If the remote
doesn't know the previous session was closed, he might keep
on sending packets to that port. If we always start off trying
to open the same UDP port, we might get those packets intermixed
with the new ones.

This is occasionally an issue when testing RTSP stuff with
DSS, perhaps also with other servers.

rtpdec: Use our own SSRC in the SDES field when sending RRs · ad7beb2c

Martin Storsjö authored Jan 21, 2012

The s->ssrc field is the sender's SSRC, we use ssrc + 1 to get
a collision free "unique" SSRC for ourselves in the RR part.
The SDES block in the RTCP packet should describe ourselves,
not the sender.

This was fixed for the RR part in 952139a3, but wasn't
fixed for the SDES part until now.

This could cause some Axis cameras to send RTCP BYE packets
to us due to the SSRC collision.
