[issue2685] Input file names with colons aren't seen by ffmpeg

2011-05-12 Thread Luca Barbato

Luca Barbato lu_z...@gentoo.org added the comment:

It a non so apparent normal behaviour, ffmpeg accepts uris, assuming the default
protocol being file://

so a:b.mp3 got parsed as protocol a resource b.mp3 I'm afraid.

2011-01-30 Thread Luca Barbato

Luca Barbato lu_z...@gentoo.org added the comment:

Looks like that patch does the bare minimum to fix it and I'd apply it for now.

The more generic solution is to chain the full mpegts demuxer like we do for
rtp_asf.

Could you please attach the wireshark dump (or the text from the rtsp session)?

2010-12-17 Thread Luca Barbato

Luca Barbato lu_z...@gentoo.org added the comment:

That's because the whole machinery got broken by the fact the codec defaults and
the stream defaults now are different (one is 0/0 the other 0/1). I have a
stupid patch to fix that by overwriting the value.

Still we should either rethink this monster.

[issue2435] FFserver desync while streaming mpegts

2010-12-17 Thread Luca Barbato

New submission from Luca Barbato lu_z...@gentoo.org:

Not sure if it is a regression but I'm having my share of issues trying to make
something apparently simple:

- prepare a streamcopy feed

 ffmpeg -i source -vbsf foo -vcodec copy -acodec copy http://host/feed.ffm

- serve it as mpegts 

Enjoy the full video desync.

[issue2436] ffm http output doesn't support bitstream filters

2010-12-17 Thread Luca Barbato

New submission from Luca Barbato lu_z...@gentoo.org:

Due how it is written, if you want to do streamcopy and reformat as in

ffmpeg -i source -vbfs foo -abfs bar -vcodec copy -acodec copy 
http://host/feed.ffm

You end up with a completely corrupted feed.

Glaring example: h264+aac source. In that case you additionally have also a
problem with AAC extradata not being properly forwarded.

The best solution could be having an explicit flag to trigger remote
configuration or not. Using the normal code seems to have an issue or ffserver
is even more broken than should.

I have no strong opinion regarding the macro value, INET6_ADDRSTRLEN

 which other application has a callback to let the user analize low level
 packets to then reject them.
 also, there is your OS firewall, 3rd party firewalls, LD_RRELOAD over the
 network code, ...
 

 also your patch would require changes to every single user application
 to have any effect.

 No it wouldn't, existing apps would be unaffected, because as you say below 
 this
 would be an API change.  Whatsmore, it could be implemented as optional by
 enabling it using a build switch.
 
 It requires every user application to add a callback, and add functionality to
 detect bad RTP packets.
 this is not reasonable, rejecting incorrect packets belongs in rtp/udp/rtsp
 not the user application
 

 If you want an extension of libavformats API this is possible but only
 after someone proofed the need for such change, that is someone MUST
 read the RFCs about RTPRTSPSDP and then explain exactly 

 * why the *SRC  SEQ numbers are not sufficient.

 If i'm opening an SDP file or just directly opening an rtp:// URL (I'm 
 opening
 an SDP file) in order to wait for an RTP stream to be sent to me, there is
 nowhere I can specify those numbers.  Even if I could, there is no formal
 mechanism for my program to get those numbers from the sender, so I wouldn't
 know which one was the one to throw away and which to keep. 
 
 you can specify the IP address of the sender in the rtp URL i would assume
 
 Also, lazy firmware
 implementers can just set the SSRC to 0 (and do, I've seen it), so multiple
 streams could have the SSRC 0, becoming indistinguishable.
 
 8.2 Collision Resolution and Loop Detection
 
Although the probability of SSRC identifier collision is low, all RTP
implementations must be prepared to detect collisions and take the
appropriate actions to resolve them.
 
 so there is no indistinguishable SSRC in RTP.
 

 * what exact attack scenario is possible due to this

 Multiple streams being sent in to a transcoding server that receives RTP 
 streams
 and outputs them to eg. a Flash client using RTMP.  There's only 65535 port
 numbers to choose from, malicious attackers can likely send valid camera 
 data to
 port(s) being used for receiving streams.
 
 How does your callback detect an attacker?
 

 * how this can be fixed

 I've posted a sample diff in this issue which fixes this (proof-of-concept), 
 by
 allowing the calling code to register a callback function which can check the
 source network address to make sure it's the address (ie. the address of the
 sender; a network camera in this case) it expected to receive the packet 
 from. 
 It can return zero or nonzero to reject or accept the packet.
 
 9.2 Authentication and Message Integrity
 
Authentication and message integrity are not defined in the current
specification of RTP since these services would not be directly
feasible without a key management infrastructure. It is expected that
authentication and integrity services will be provided by lower layer
protocols in the future.
 
 i think this should be a sufficient final awnser to your problem

if you want to be 100% sure you can use srtp (and/or have rtsp do its
work...)

[issue1688] AVPacket should provide a packet's source address

 RTP has ssrc and seq numbers to get them right he will probably need
 access to your network and if he does have access to it the IP will
 not help you
 
 But ffmpeg is receiving 2 valid video streams; both have valid ssrc and seq
 numbers.  It doesn't know which is the right one, as is evidenced by the 
 current
 behaviour where is spews out errors and occasionally shows frames from each of
 the video streams.

so the ssrcs are the same for both of the streams? otherwise we got a
but that should be fixed in the rtp demuxer ^^;

 about UDP if you only want packets from a specific IP the correct way
 is to specify this IP during open somehow not to accept all packets
 and after wasting resources to a DOS attack reject packets.
 
 'somehow'?  How, exactly, do you do that with incoming UDP packets?

if the ssrc is different then is easy otherwise... we have to think a
bit more ^^;

 This part of the patch is a mistake, it should be taken out. I am not 
 able to test without it in my copy, but I forgot to remove it before 
 creating the patch.
 

there is also some 2space indentation that could be removed.

In short your patch is about parsing correctly the control line in sdp
(if I read correctly). So it isn't just about msrtsp I think.

Please do not force us to remove your account. I mark it as wont_implement. You
may feed the configure with additional -D_NETBSD_SOURCE=1 and that should make
it build I think.
