ByteBuffer byteBuffer = ByteBuffer.wrap(convertFileToByteArray(file)); DataChannel.Buffer buf = new DataChannel.Buffer(byteBuffer, isBinaryFile); dataChannel.send(buf); On the other side, this callback should be called regardless of isBinaryFile value :

Video Tag Local File Download Cordova Android

由 走远了吗. 提交于 2019-12-06 12:23:09
问题 I'm trying to download a video and then play it using apache Cordova 3.4.0, but I don't know if I can use the video tag. There are some plugins that work for using the video tag like Html5Video but it needs the video file to be present in the app folder. There are other plugins that use other players and load the file using the file path, but since the file download now uses Html5 urls, and the fullPath gives me a realitive path to the file system, it's really impossible to know where the

I am writing a program that requires the use of XMODEM to transfer data from a sensor device. I'd like to avoid having to write my own XMODEM code, so I was wondering if anyone knew if there was a python XMODEM module available anywhere? def xmodem_send(serial, file): t, anim = 0, '|/-\\' serial.setTimeout(1) while 1: if serial.read(1) != NAK: t = t + 1 print anim[t%len(anim)],'\r', if t == 60 : return False else: break p = 1 s = file.read(128) while s: s = s + '\xFF'*(128 - len(s)) chk = 0 for c in s: chk+=ord(c) while 1: serial.write(SOH) serial.write(chr(p)) serial.write(chr(255 - p))

由 爱⌒轻易说出口 提交于 2019-12-06 06:09:45
I am new to netty and I am attempting to transfer a chunkedfile from a server to a client. Sending the chunks work just fine. The problem is on how to handle the received chunks and write them to a file. Both methods that I tried give me a direct buffer error. Any help would be greatly appreciated.

AWS S3 signed url encode resulting “SignatureDoesNotMatch”

由 跟風遠走 提交于 2019-12-06 05:57:39
问题 I am using cordova file transfer to dowload a file from aws s3 using signed url, since cordova filetransfer encodes the uri, the "%" in signature is converted to "%25", thus, results in signature mismatch 回答1: Try setting up your options like so: options = { fileKey: 'file', fileName: name, chunkedMode: false, mimeType: 'audio/3gpp', httpMethod: 'PUT', // Important! headers: { 'Content-Type': 'audio/3gpp' // < Set explicitly otherwise it becomes multipart/form-data which won't work with S3 },
