playback

问题 I am working on a half-duplex VOIP call app. In that I am trying to play tones along-with vibration during floor exchanges - floor exchanges are done to change the talker from A to B or vice-versa for a half-duplex call. If I try to play tones using AudioServicesPlayAlertSound, then it plays sound when user gets the call, but not during floor exchanges, due to possible mixing issues with call audio. So I replaced AudioServicesPlayAlertSound with AVAudioPlayer's play function. So, now I am

问题 How can I hide the play button that's in the center of the video screen in JW Player? I'm using version 5.4 of the player and I am embedding it using their own 'JW Embedder' technique. I've tried the following with no luck: jwplayer("myPlayer").setup({ file: 'myMediaFile.mp4', image: 'myPosterFile.jpg', controlbar: 'bottom', icons: false }); I've read somewhere that this may have been removed with version 5.0 and must now be done with a skin. But, I also read that it returned in version 5.1 .

问题 I am trying to find out if a video file is corrupted or not. I am using FFmpeg to transcode a video file. However, when it gets to a file that not playable and is damaged, it stops running. I want to know if there is a way to output the FFmpeg command into a text file and then be able to tell which file is corrupted from the text file. When I run FFmpeg on one of the corrupted vide, I find this information. built with gcc 9.1.1 (GCC) 20190807 configuration: --enable-gpl --enable-version3 -

问题 I'm trying to obtain playback video streams from some Axis and Hikvision cameras, using Onvif. I'm doing this in a C# application, and the resulted stream is played in VLC. Using the FindRecordings/GetRecordingSearchResult calls and then GetReplayUri I can obtain the playback stream (RTSP/H264), but here I have this problem: this behaves like a live stream - I can only use play and pause. I cannot use the time cursor to seek, cannot play in reverse. So I find this unusable for a playback

问题 at Windows 10 there is a Music Feature(Pic Below): So my Question is: How can I access this information with C# and which libraries do i need? Thanks for helping 回答1: Excuse me for my ignorance, but if I am correct, this widget is a pop up of Spotify, isn't this? In that case, you only have to check the MainWindowsTitle of spotify process. var spotify = Process.GetProcessesByName("Spotify"); foreach (var song in spotify) { Console.WriteLine(song.MainWindowTitle); } Console.ReadLine(); Don't

问题 I'm developing an application for iOS, that uses the RemoteIO audio unit to record audio from the microphone, process it and output to the speakers (headset). Currently I use a single channel (mono) for input and output. What I'd like to do, is to allow the users to choose an output speaker: left-only, right-only or both. My current code supports only the "both" setting - the same sound is coming from both speakers. Here's how I set the stream format (kAudioUnitProperty_StreamFormat) of the

问题 I’m trying to find a good way to play background music in Unity 3D. I want the music to keep playing consistently through scene loads. Don’t Destroy on load is fine and works, but every time I load the same scene, it makes another music game object because the scene itself has the game object in it. How can I solve my problem? I am a “beginner” (kind of), so I would like code I can understand. 回答1: I'd hands down recommend starting with an Asset like 'EazySoundManagerDemo'. It needs a little
