由 两盒软妹~` 提交于 2019-12-10 18:05:04

Audio recording with HTML5

由 ▼魔方 西西 提交于 2019-12-09 22:55:26
问题 I'm trying to implement audio recording in a website. Basically the user should be able to press a button and speak something into the microphone. The recorded audio should then be sent to the server for further processing. I realise that you can do this with Flash, but for now I'm trying to avoid that. I found several resources on the internet about it (i.e. link) but as it seems, this functionality is not widly supported yet. I experienced differences betweet the used browser and between

When to use “Follow Redirects” & “Redirect Automatically” while recording with jmeter.

由 本秂侑毒 提交于 2019-12-09 14:54:22
问题 I want to know the difference between Follow Redirects and Redirect Automatically while recording with Jmeter. Also what effect will both these have when used with Retrieve all Embedded Resources from HTML 回答1: Redirect automatically , will not consider redirect as a separate request where as Follow redirects will consider each redirection as a separate request. This difference can be visualized in the Listener (View Results Tree). If Retrieve all Embedded Resources from HTML is checked, it

Android: Recording SoundPool output

由 房东的猫 提交于 2019-12-08 17:13:49
问题 I'm allowing the user to push buttons to play sounds via a SoundPool. Is it possible to record whatever the SoundPool is playing so that the user can record a sequence of sounds? 回答1: Actually there is no possibility to catch played sound. I had the same wish to do this, but for now, it is just possible with record the output of the speaker. For this, You have to use MediaRecorder and record just "live". But I don´t think it is a good solution, there will be much background sounds. 来源： https:

Capture mac screen

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-08 02:11:20
问题 What is the best way to record the mac screen with cocoa? I know there are many examples at the apple developer reference library. SonOfGrab explain how to capture the screen with quartz but also that it isn't enough fast to use it to grab many frames every second. OpenGLScreenSnapshot has same results but it isn't fast, too. OpenGLScreenCapture seems to be the best way to do it but XCode prompts me many errors because it's made for 10.4 and it requires old Quicktime commands I think they

Application-Bridge for iChat Audio Channels

由 大兔子大兔子 提交于 2019-12-06 12:04:25
This question was migrated from Ask Different because it can be answered on Stack Overflow. Migrated 8 years ago . There is a feature in GarageBand that allows you to record iChat Audio sessions directly into GarageBand. When you are the host of an iChat conference ( you called the other party/parties), you can open GarageBand and hit record, and GarageBand will ask you if you wish to record the conference. Say yes, and GarageBand creates distinct tracks for all members of the conference, and records isolated audio from them into their own channel, complete with their username (or real name as

MediaMuxer.nativeWriteSampleData always peroidically blocks for about one second during video recording

由 末鹿安然 提交于 2019-12-06 08:36:52
I am doing android video recording using mediacodec + mediamuxer, and now I can record video and generate mp4 file which can be played. The problem is that I find the recorded video will seize for about one second some time. So I launched traceview and I find MediaMuxer.nativeWriteSampleData() cause the problem. Sometimes this function is very fast and returns within several micro-seconds, but sometimes this function is very slow and will consume about one second or so, and the video blocks at that time. I do not know why this function will perform so varying from time to time. The recording
