java - Android library to stream local stored audio via RTP -

-

is possible transmit local stored audio file (e.g. mp3) via rtp? e.g. there mp3 file taken input , converted/packed rtp packets , send on network. there libraries, solutions, examples?

thanks!

//edit: want make phone call sip , send/stream local stored audio file called, can hear it.

check possible webrtc solutions in section 5.... have not worked sounds tailor made trying do. maybe use ondello api.

or

you have build session sip/rtp connection , providing backdoor (jni , native code) buffer receives microphone raw stream or output buffer microphone raw stream encoded to... doing load rtp stream on sender side prerecord audio.

with access buffer, in middle of sip session, can xcopy in-memory version of audio file, swapping stream sip call. party @ other end of call hear audio audio file not microphone content.

if not success w/ sip/rtp apis, check java networking lib allows build sip connections ground , swap buffers in manner want.

see answer on thread

option 2, client server ( no jni native code req'd here )

upload audio sender , serve server rtsp receiver. youtube video used ( still may ) encoded rtsp clients , pretty known server-to-android-media-player scenario. believe sdp description of such file , log of session...

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
