问题 Is there a way to slowdown/speedup the speed of music playback, currently I'm using MediaPlayer class and cannot find any functions that do this. Is there a way to playback music with variable speed? 回答1: Unfortunately MediaPlayer does not allow it. You can vote for this feature to be included in Android by default here: http://code.google.com/p/android/issues/detail?id=1961 The best apps that support it that I found are ACast (which has very good support for downloading podcasts, which is

mux raw h 264 to an mp4 file, some odd errors

不羁的心 提交于 2019-12-07 07:43:27
What I'm doing is on an IOS app with Xcode 7.3. I got h264 data from an ip camera using UDP,the data can be decoded and displayed rightly (decoded by ffmpeg). Now I want to mux the raw H264 data to an mp4 file(some users may want to record what they are watching on his cell-phone), using ffmpeg. Nothing wrong happened when the code is running, and the result file can be played normally with QuickTime on my computer. But when played on iphone with iphone's default video player, it can't be played normally.Here is my code. Wish someone could tell me what should I do, thanks! init AVFormatContext

问题 I just can't seem to locate what's wrong with this video snippet. <video poster="sample.jpg" loop autoplay controls muted playsinline> <source type="video/webm" src="sample.webm"></source> <source type="video/mp4" src="sample.mp4"></source> </video> The video plays without any problems in Safari (haven't tested against earlier versions of iOS, but my only concern there is the autoplay issue?), but on Chrome the only thing I see is the cover image and a play button that doesn't trigger

How to have an object in Unity 3D that stays in scenes and does not recreate

前提是你 提交于 2019-12-05 20:13:51
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. I'd hands down recommend starting with an Asset like 'EazySoundManagerDemo'. It needs a little refactoring and refinement (ie it uses 3 arrays of audios with 3 sets of accessibility functions instead of

How to get redirector.googlevideo.com link from a Google drive video

不想你离开。 提交于 2019-12-05 16:48:35
问题 I have a google drive video file (like https://drive.google.com/file/d/FILE_ID/view) and I want to get its redirector.googlevideo.com link. How do sites like http://api.getlinkdrive.com/ do it? I've tried using the Google Drive REST API, (both v2 and v3) but still can't find a way to do it. Many tv-show and movie sites host their content on google drive, and use this "cloaked" URL that expires so you can't for example embed it somewhere else. The closest I've gotten is by going to docs.google

How to simulate hardware media control buttons on an Android emulator

别说谁变了你拦得住时间么 提交于 2019-12-05 16:47:09
问题 Android supports hardware play / pause buttons on headsets and attached devices. I am trying to find a way to test support for those devices on an emulator. The Android documentation talks about how to add support for hardware playback controls, but, unfortunately, I can't find documentation of how to emulate them. Thanks! 回答1: You can send keyevents using adb adb shell input keyevent <keycode> keycode for play - 126, pause - 85 (see KeyEvent) 回答2: There is another way to do this, from an
