video - MPEG 2 - Adding custom tags via editing the source -

-

I'm looking for advice and what I want to do is possible.

I have been asked to create something similar to the ID3 MP3 tag which can be used with MPEG2 / MPEG-TS video files. Because I'm a raw person, I was just thinking of dumping some type of XML structure within the file, however, this causes problems with applications that try to decode / run the file because the app is in the file XML / ASCII data is not expected. The end of the file 'command' which can be modified at the end of the MPEG files, and I can dump my XML after that part.

According to the compatibility, I only need to avoid the video file by breaking a video. The app that is reading the information tagged will be parsed with an application that I have written so far.

Any thoughts? Or am I suggesting impossible?

Thank you.

Any program decoding an MPEG 2-ts file repeated checking of an 188 byte packet Still working. If you look at the hex, you will see a 0x47 byte, which is also a sync byte (first byte) of each pack of 188 bytes. This is the reason that adding the XML data to the file will screw any decoders.

What you can do, add your packet or kidnap the tap-pid packet, usually at the beginning of an MPEG-2-TS file. Unfortunately, to do this properly, you want this data to be in the network information table, which is not already available. This means that you may have to add a reference to the NIT in PMT. Everyone needs advanced knowledge of transport knowledge and parsing / writing ability.

You can get rid of adding the packet at the beginning of the file without adjusting the context of the clock or just abort the existing null-pid packets (no clock reference changes required) after that A packet ID is used in the new packet, which probably will not be used as 81 9. Without modifying PMT in terms of NIT, it will not be a fully valid MPEG2-TS due to the unearned PID, but perhaps it will still work most commercial decoders

It is not very understandable I am sure, because you are just trying to add some tag information and are not familiar with MPEG2-TS but the standard that defines the exact format is Be careful this is a very heavy reading. If you want to go light (and cheap), then you can be away from now.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
