read / write mp4 id3 tags with PHP

由 筅森魡賤 提交于 2019-12-12 16:57:48
问题 I need to be able to at very least read and preferably write id3 tags connected to an mp4 video file. I've looked into using getId3() but it's got so many functions that finding those applicable to mp4 video files is difficult and the write demo files don't work on mp4 files 回答1: ID3 tags, as such, are only generally used on MP3 streams. I believe that MPEG 4 uses its own metadata format (within the meta atom). For details, see http://atomicparsley.sourceforge.net/mpeg-4files.html. 来源： https:

Python Write Replaces “\n” With “\r\n” in Windows

由 妖精的绣舞 提交于 2019-12-10 09:24:56
问题 After looking into my question here, I found that it was caused by a simpler problem. When I write "\n" to a file, I expect to read in "\n" from the file. This is not always the case in Windows. In [1]: with open("out", "w") as file: ...: file.write("\n") ...: In [2]: with open("out", "r") as file: ...: s = file.read() ...: In [3]: s # I expect "\n" and I get it Out[3]: '\n' In [4]: with open("out", "rb") as file: ...: b = file.read() ...: In [5]: b # I expect b"\n"... Uh-oh Out[5]: b'\r\n'

由 风流意气都作罢 提交于 2019-12-07 05:13:27
问题 I am doing a new android app. I want to create a folder in "Android" folder which is available in sdcard. Before that I want to check whether the folder has read/write permission. How can I get that? can anyone help me to do this. 回答1: You do it the old-school java way. Create a file object and call canWrite() and canRead() . File f = new File("path/to/dir/or/file"); if(f.canWrite()) { // hell yeah :) } 回答2: To create a folder in Android folder the best way is: File path = getExternalFilesDir

Swift - Read/write array of arrays to/from file

由 此生再无相见时 提交于 2019-12-05 14:18:11
Here are my files. How can I write this array: var listOfTasks = [["Hi", "Hello", "12:00"],["Hey there", "What's up?", "3:17"]] to a .txt file ( file.txt )? I know there are other questions about this, but they're in other languages (not Swift). I'd like for it to work on an actual iPhone. I'm happy to provide additional information if necessary. I'm new to Swift, so excuse my question if it seems too simple. NOTE: I am asking specifically about arrays containing arrays. Thanks in advance! redent84 Already answered you in your other question : Here's a full working Playground sample: let

Open file with system application in a Progressive Web App

由 最后都变了- 提交于 2019-12-05 05:29:18
I'm trying to figure out if it is possible to open a file from a Progressive Web App with the default system application. The idea is that a PWA would store for offline use some files (e.g. a .docx file), and that the user would be able to open them without (re)downloading them. The ideal situation would be that the PWA is able to load into memory the file, make it accessible to the default system application for that file type (e.g. Word for .docx files), watch for changes (i.e. the user saves edits), and then store it back into the PWA storage. Even a read-only solution would be great. Since

Is SDK for NFC reader/writer acr122u device required to build read/write application?

由 谁说我不能喝 提交于 2019-12-03 07:35:56
问题 i have nexus s, nexus 4 and 6 mifare nfc tags, and want to make an desktop application with nfc reader/writer acr122u device (which i haven't bought it yet). But apart from android sdk, is there some other SDK needed for making an desktop application through eclipse with java? or i can directly buy and use the acr122u device (without sdk) and make the app through eclipse? If the SDK is needed, is there any link to download it for free or i have to buy it from the vendor itself? One more thing
