I'm new in NAudio and Audio Programming, and I have questions about streaming in 256kbps, NAudio have some codec to work with this bitrate? I know about MP3 Encode in NAudio don't support. Can I use other codec like ACC in NAudio or another option with this quality to encode?
I'll need to streaming in first side and receive streaming in application on the other side (unicast).
Some ideas?
Thanks!

as the title shows, is there any methods I can use to play multiple videos continuously using simple rtmp client(my rtmp server is wowza)? Here is the way I think:
when the first video is about to be finished，open a new thread to send a new createStream command and a new play command and get the video rtmp packet and put them into a buffer list, when the first video is finished, then play the video rtmp in the buffer list..
Can this way be available or are there any other recommended methods to achieve it? Any suggestion will be appreciated, thanks!
While the functionality is not built-in, Wowza does have a module called StreamPublisher to allow you to implement a server-side type of playlist. The source code for the module is available on GitHub. A scheduled playlist of multiple VOD files is streamed as a live stream, similar to a TV broadcast.
Is it possible to stream video and audio to a rtmp://-server with GPUImage?
I'm using the GPUImageVideoCamera and would love to stream (video + audio) directly to a rtmp-server.
I tried VideoCore which streams perfectly to e.g. YouTube, but whenever I try to overlay the video with different images I do get performance problems.
It seems as GPUImage is doing a really great job there, but I don't know how to stream with that. I found issues on VideoCore talking about feeding VideoCore with GPUImage, but I don't have a starting point on how that's implemented...
Trying to split HLS TS Stream audio from video, audio is AAC format.
The gole is to have some sort of AVAsset that I can later manipulate and then Mux back to the video.
After searching for a while i cant find a solid lead, can someone give me a educated direction to take on this issue ?
You can use the ffmpeg/libav library for demuxing the ts. To load the audio back as an AVAsset, it might be necessary to load it from a URL, either by writing temporarily to disk or serving with a local http server within your program.
I think you might run into some trouble in manipulating the audio stream, assuming you want to manipulate the raw audio data. That will require decoding the AAC, modifying it, re-encoding, and re-muxing with the video. That's all possible with ffmpeg/libav, but it's not really that easy.
Hi
I am using the NAudio library at http://naudio.codeplex.com/
I have this hardware made by some manufacturer which claims to send
audio with the following characteristics.
aLaw 8khz, AUD:11,0,3336,0
Not sure what it all means at this stage.
I received bunch of bytes from this device when a user speaks into the
equipment.
Hence I am constantly recieving a stream of bytes at particular times
At this stage I have been unable to decode the audio so I can hear
what is spoken into the device with my headphones.
I have tried writing the audio to a file doing code like
FWaveFileWriter = new WaveFileWriter("C:\Test4.wav",
WaveFormat.CreateALawFormat(8000, 1));
And have been unable to playback the sound using the sample demo apps.
I have tried similar code from
http://naudio.codeplex.com/Thread/View.aspx?ThreadId=231245 and
http://naudio.codeplex.com/Thread/View.aspx?ThreadId=83270
and still have not been able to achieve much.
Any information is appreciated.
Thanks

If you are definitely receiving raw a-law audio (mono 8kHz) then your code to create a WAV file should work correctly and result in a file that can play in Windows Media Player.
I suspect that maybe your incoming byte stream is wrapped in some other kind of protocol. I'm afraid I don't know what "AUD:11,0,3336,0" means, but that might be a place to start investigating. Do you hear anything intelligible at all when you play back the file?
I am working on a project (a digital camera) that should be able to take still images and short video clips and make those available to the host. As well as being able to stream live video.
Which USB class[es] should I use?
Should I use PTP (for still images and video) and USB Video Class for streaming?
Does PTP support transfer of video?
Does PTP support video streaming?
For static objects PTP is better since it does have a definition for an object. Current Canon DSLRs are also capable of "streaming" live video via standard PTP transaction mechanism. However, real streaming would benefit from isochronous transfer so UVC is better for streaming.
You can also have both classes implemented in a single device and have objects transferred bia PTP set of endpoints and stream via UVC endpoint.
