I have tried to use jwplayer and flowplayer, for jwplayer I have found some equalizers but they don't work for live audio streams, I need to have a "monitor" for my live stream, so I tought I could use a equalizer (if there is sound, the bars will be moving, if there isn't any sound, the bars will be static...).
I want to have a page with my rtmp stream playing and an equalizer to know if the stream is having sound or not... Should I create my own player? if yes, please point me in the right direction...
If there are any already created players that support this feature, pelase let me know!
Thanks in advance!

I am developing an application which require to apply audio effect on recorded video.
I am recording video using GPUImage library. I can successfully done with it. Now, I need to apply audio effect like Chipmunk, Gorila, Large Room, etc.
I looked into Apple's document and it say that AudioEngine can't apply AVAudioUnitTimePitch on Input Node (as Microphone).
For solving this problem, I use following mechanism.
Record video & audio at same time.
Play video. While playing video, start AudioEngine on Audio file and apply AVAudioUnitTimePitch on it.
[playerNode play]; // Start playing audio file with video preview
Merge video and new effected audio file.
Problem :
User have to preview a full video for audio effect merge. This is not a good solution.
If I set volume of playerNode to 0 (zero). Then It record mute video.
Please provide any better suggestion to do this things. Thanks in advance.
I want to save avplayer playing byte data save on document directory.(like recording) but i don't want record side voice only song music.
AVAudioRecorder is take speaker voice so, thats why i want to save player live streaming data.
So, Please give any suggestion and source code which apply in my code.
I would like to be able to have music playback that can allow me to make the audio tinny. Like an Equalizer, i would like to alter the Channel EQ of the audio using a slider to choose whether the audio is full and rich, or light and tinny during playback of the audio file. Is this implementation possible?
Thanks,
We're using Wowza 3.5 in our server to stream videos, and JW Player for the player.
The streaming of videos are working fine when viewed in iPhone and iPad.
What we are trying to do now is, when a video is playing on an iOS device and a user paused it we would like the video to buffer (download) while it is paused so even if the user lost connection to the internet he could still watch the video until. Currently it is only buffering for 30 seconds to 1 minute.
How could we increase this buffer time to possibly buffer / download the whole video while the player is paused?
Is this even possible in HLS?
This is not possible when you're playing a video using HLS in a webpage using the default browser.
You need to create your own app to control the video buffer when playing videos using HLS.
There is an App with Wowza called nDVR, you can pause, play and record using nDVR. Also I think you can increase the buffer length in application.xml, make sure.
I'm trying to mute the right channel for all audio apart from an audio stream that I control.
I am using a number of libraries playing audio including OpenEars for Text-to-speech and I would like all of them to only play out the left headphone speaker while I play something else out the right speaker.
I know how to play out just the right speaker creating an Audio Units stream however I am not creating the audio streams for the other libraries. Is there a way to change the default audio channel? Or is it possible to create an effort or mixer that is applied to all audio going out that mutes the right channel?
Any help/hints would be much appreciated.
If you don't need low latency audio, wich AudioUnit provides, you can try using AudioQueues to play your audio instead, AudioQueues has the highest degree of control over audio in iOS (it supports synchronization, channel control, volume gain, buffer, etc.). Here's some links to Apple's documentation :-)
