Now I am revisiting the project, I have to add pictures and video as upload content also. I want to find the best

问题 I am testing the html audio tag and I would like to make audio blob url's , like youtube or vimeo does, and add it to the "src" to start playing the audio. I've been testing with new Blob() and URL.createObjectURL() but I don't know how to use it.

Git - get all commits and blobs they created

天涯浪子 提交于 2019-11-27 19:08:40
Is there a git command that can output for every commit: id subject blobs it created with they path and size (like git ls-tree -l -r <commit> but only for created blobs) To get commits (all and output one line per commit): git rev-list --all --pretty=oneline Then split commits by space with limit of 2 and get every commit id and message To get blobs created by commit (recurse to subdirs, show merge commits, detect renames and copies, don't show commit id on first line): git diff-tree -r -c -M -C --no-commit-id <commit-sha> A bit of parsing of every line and excluding some of them — and we get

问题 I need to add jpeg images to firestore db records. My preferred way would be in a Blob as I have used in Sqlite records. I have run into some problems in trying this. The following is my best try so far: public Blob getImage() { Uri uri = Uri.fromFile(new File(mCurrentPhotoPath)); File f1 = new File(mCurrentPhotoPath); URL myURL = null; try { myURL = f1.toURI().toURL(); } catch (MalformedURLException e) { e.printStackTrace(); } Bitmap bitmap = null; BitmapFactory.Options options = new

I am developping an application where I recieve image data stored in a uint8Array. I then transform this data to a Blob and then build the image url. Simplified code to get data from server: var array; var req = new XMLHttpRequest(); var url = "img/" + uuid + "_" +segmentNumber+".jpg"; req.open("GET", url, true); req.responseType = "arraybuffer"; req.onload = function(oEvent) { var data = req.response; array = new Int8Array(data); }; Constructor: out = new Blob([data], {type : datatype} ); The Blob contsructor is causing problem. It works fine on all browsers except Chrome on mobile and

How do I convert BLOB into VARCHAR in MySQL?

本秂侑毒 提交于 2019-11-27 18:18:25
问题 It is in a shared host and I access with Navicat. I have field with BLOB and I want to convert it into VARCHAR. I've tried in the design screen but everything was lost. I backed up. 回答1: try using this, I found it some time ago, you can convert it to char , not to Varchar2 or Varchar , haven't test it yet. Try: CAST(a.ar_options AS CHAR(10000) CHARACTER SET utf8) MySQL treat data unique. Hence there is a difference between Blob and Text. Text simply means a text string stored as original, not

Overcomplicated oracle jdbc BLOB handling

穿精又带淫゛_ 提交于 2019-11-27 18:09:23
When I search the web for inserting BLOBs into Oracle database with jdbc thin driver, most of the webpages suggest a 3-step approach: insert empty_blob() value. select the row with for update . insert the real value. This works fine for me, here is an example: Connection oracleConnection = ... byte[] testArray = ... PreparedStatement ps = oracleConnection.prepareStatement( "insert into test (id, blobfield) values(?, empty_blob())"); ps.setInt(1, 100); ps.executeUpdate(); ps.close(); ps = oracleConnection.prepareStatement( "select blobfield from test where id = ? for update"); ps.setInt(1, 100)
