Tcpmp unknown file format

Everything's working except the audio. It was removed from the official install package because of intellectual property considerations. No audio, just the video. The only choice is AAC for audio. What else can I do? You need the AAC codec in order to get audio. Check your PM. Watching itunes movies on treo I've been able to watch converted DVD on my treo , but would also like to buy TV shows and videos from itunes. Any help out there?

Unknown file format I've followed the instruction for handbreak to the T, but my treo keep giving me thi serror message. I dont understand, the movies when converted are fine, they play. I reinstalled, tcpmp, with all the plug-ins even the aac one. HELP, out of ideas. Unknown file format Yes they play fine in Quicktime. I find it odd myslef, but I can't seem to find a reason nor a solution. I might of accidently removed my SD card, but evrythinh else works fine.

MPG files with no problem. How about playing apple MOV videos m4v, mov that are not protected not from itunes store and are encoded with h codec? In short, play none protected h videos. Popcorn and Mactheripper I was wondering if anyone has used Mactheripper and Popcorn for their movie conversion.

I understand that these might cost some money but if it was easier I think it might be worth it. Please let me know. In these cases the dump shows the same exact code that would filter the input file or the network interface without -d.

However, when neither -r nor -i is specified, specifying -d prevents tcpdump from guessing a suitable network interface see -i. For each network interface, a number and an interface name, possibly followed by a text description of the interface, are printed.

The interface name or the number can be supplied to the -i flag to specify an interface on which to capture. This can be useful on systems that don't have a command to list them e. This combination may be repeated with comma or newline separation. Algorithms may be des-cbc , 3des-cbc , blowfish-cbc , rc3-cbc , castcbc , or none.

The default is des-cbc. The ability to decrypt packets is only present if tcpdump was compiled with cryptography enabled. If preceded by 0x, then a hex value will be read. By presenting IPsec secret key onto command line you make it visible to others, via ps 1 and other occasions. In addition to the above syntax, the syntax file name may be used to have tcpdump read the provided file in.

The file is opened upon receiving the first ESP packet, so any special permissions that tcpdump may have been given should already have been given up. If that address or netmask are not available, available, either because the interface on which capture is being done has no address or netmask or because the capture is being done on the Linux "any" interface, which can capture on more than one interface, this option will not work correctly.

An additional expression given on the command line is ignored. Savefiles will have the name specified by -w which should include a time format as defined by strftime 3. If no time format is specified, each new file will overwrite the previous. Whenever a generated filename is not unique, tcpdump will overwrite the pre-existing data; providing a time specification that is coarser than the capture period is therefore not advised.

On Linux systems with 2. If the -D flag is supported, an interface number as printed by that flag can be used as the interface argument, if no interface on the system has that number as a name. Note that in monitor mode the adapter might disassociate from the network with which it's associated, so that you will not be able to use any wireless networks with that adapter. This could prevent accessing files on a network server, or resolving host names or network addresses, if you are capturing in monitor mode and are not connected to another network with another adapter.

This flag will affect the output of the -L flag. If -I isn't specified, only those link-layer types available when not in monitor mode will be shown; if -I is specified, only those link-layer types available when in monitor mode will be shown.

In this mode, packets are delivered to tcpdump as soon as they arrive, rather than being buffered for efficiency. The names to use for the time stamp types are given in pcap-tstamp 7 ; not all the types listed there will necessarily be valid for any given interface. If the time stamp type cannot be set for the interface, no time stamp types are listed.

Note that availability of high precision time stamps nanoseconds and their actual accuracy is platform and hardware dependent. Also note that when writing captures made with nanosecond accuracy to a savefile, the time stamps are written with nanosecond resolution, and the file is written with a different magic number, to indicate that the time stamps are in seconds and nanoseconds; not all programs that read pcap savefiles will be able to read those captures.

If the precision specified is less than the precision of time stamps in the file, the conversion will lose precision. The default is microsecond resolution. When reading packets from a savefile, using --micro truncates time stamps if the savefile was created with nanosecond precision. In contrast, a savefile created with microsecond precision will have trailing zeroes added to the time stamp when --nano is used.

This is useful for interfaces that perform some or all of those checksum calculation in hardware; otherwise, all outgoing TCP checksums will be flagged as bad. Useful if you want to see the data while capturing it. The list of known data link types may be dependent on the specified mode; for example, on some platforms, a Wi-Fi interface might support one set of data link types when not in monitor mode for example, it might support only fake Ethernet headers, or might support This option can be used several times to load several MIB modules into tcpdump.

This is useful only if you suspect a bug in the optimizer. Not available on all platforms. Print less protocol information so output lines are shorter. Note that taking larger snapshots both increases the amount of time it takes to process packets and, effectively, decreases the amount of packet buffering. This may cause packets to be lost.

Note also that taking smaller snapshots will discard data from protocols above the transport layer, which loses information that may be important. NFS and AFS requests and replies, for example, are very large, and much of the detail won't be available if a too-short snapshot length is selected.

If you need to reduce the snapshot size below the default, you should limit snaplen to the smallest number that will capture the protocol information you're interested in. Setting snaplen to 0 sets it to the default of , for backwards compatibility with recent older versions of tcpdump. For example, the time to live, identification, total length and options in an IP packet are printed.

When writing to a file with the -w option and at the same time not reading from a file with the -r option, report to stderr, once per second, the number of packets captured. In Solaris, FreeBSD and possibly other operating systems this periodic update currently can cause loss of captured packets on their way from the kernel to tcpdump. For example, telnet SB SE options are printed in full. With -X Telnet options are printed in hex as well.

They can later be printed with the -r option. This output will be buffered if written to a file or pipe, so a program reading from the file or pipe may not see packets for an arbitrary amount of time after they are received.

Use the -U flag to cause packets to be written as soon as they are received. The filename extension. Tcpdump itself doesn't check the extension when reading capture files and doesn't add an extension when writing them it uses magic numbers in the file header instead.

However, many operating systems and applications will use the extension if it is present and adding one e. See pcap-savefile 5 for a description of the file format. In addition, it will name the files with enough leading 0s to support the maximum number of files, allowing them to sort correctly.

Used in conjunction with the -G option, this will limit the number of rotated dump files that get created, exiting with status 0 when reaching the limit. If used in conjunction with both -C and -G, the -W option will currently be ignored, and will only affect the file name. The smaller of the entire packet or snaplen bytes will be printed. Note that this is the entire link-layer packet, so for link layers that pad e. Ethernet , the padding bytes will also be printed when the higher layer packet is shorter than the required padding.

In the current implementation this flag may have the same effect as -xx if the packet is truncated. This is very handy for analysing new protocols. In the current implementation this flag may have the same effect as -XX if the packet is truncated.

For example, specifying -z gzip or -z bzip2 will compress each savefile using gzip or bzip2. Note that tcpdump will run the command in parallel to the capture, using the lowest priority so that this doesn't disturb the capture process. This behavior can also be enabled by default at compile time. If no expression is given, all packets on the net will be dumped. For the expression syntax, see pcap-filter 7. The expression argument can be passed to tcpdump as either a single Shell argument, or as multiple Shell arguments, whichever is more convenient.

Generally, if the expression contains Shell metacharacters, such as backslashes used to escape protocol names, it is easier to pass it as a single, quoted argument rather than to escape the Shell metacharacters. Multiple arguments are concatenated with spaces before being parsed. IPv6 is left as an exercise for the reader. The following gives a brief description and examples of most of the formats. Timestamps By default, all output lines are preceded by a timestamp.

The timestamp is the current clock time in the form hh:mm:ss. The timestamp reflects the time the kernel applied a time stamp to the packet. Link Level Headers If the '-e' option is given, the link level header is printed out. On Ethernets, the source and destination addresses, protocol, and packet length are printed. Such packets are assumed to contain an Regardless of whether the '-e' option is specified or not, the source routing information is printed for source-routed packets.

On The packet type is printed first. The three types are ip , utcp , and ctcp. No further link information is printed for ip packets. For TCP packets, the connection identifier is printed following the type. If the packet is compressed, its encoded header is printed out. If it is not a special case, zero or more changes are printed. Finally, the amount of data in the packet and compressed header length are printed.

The format is intended to be self explanatory. Csam replies with its Ethernet address in this example, Ethernet addresses are in caps and internet addresses in lower case. This would look less redundant if we had done tcpdump -n : arp who-has If the -v flag is specified, information from the IPv4 header is shown in parentheses after the IP or the link-layer header.

The general format of this information is: tos tos , ttl ttl , id id , offset offset , flags [ flags ], proto proto , length length , options options tos is the type of service field; if the ECN bits are non-zero, those are reported as ECT 1 , ECT 0 , or CE.
