Hi i built ffmpeg executable on Redhat5. I want to mix two Audio using the command multiple "ffmpeg -i INPUT1 -i INPUT2 -i INPUT3 -filter_complex amix=inputs=3:duration=first:dropout_transition=3 OUTPUT.mp3".

I enabled libflamemp3 library without any error.

[root@localhost ~]# ffmpeg -i /root/media/Katlalli.mp3 -i /root/media/Katlalli.mp3 -filter_complex amix=inputs=2:duration=first:dropout_transition=2 /root/media/OUTPutnew123.mp3

  amix -> Stream #0:0 (libmp3lame)
  Stream #0:1 -> #0:1 (mjpeg -> ?)
Encoder (codec none) not found for output stream #0:1

But when i try to combine two mp3 audio, "ffmpeg -i INPUT1 -i INPUT2 -i INPUT3 -filter_complex amix=inputs=3:duration=first:dropout_transition=3 OUTPUT.mp3".

I am getting error like

"Encoder (codec none) not found for output stream #0:1"

so please help me how to link or install "libmp3flame" on Redhat5.

  zlib

  I believe ffmpeg is trying to decode a PNG input video stream (the album art) and encode the output video stream to PNG output, but I assume you built ffmpeg without zlib support which is required for PNG encoding and decoding.

  zlib is automatically detected if available, so you needed to install the zlib headers prior to ffmpeg compilation (zlib-devel package for Red Hat 'n friends).

  omit video

  Alternatively you can keep your build and tell ffmpeg to ignore any video with the -vn output option.

  use mjpeg

  If you want to keep your build and also keep the album art then add -codec:v mjpeg as an output option. See stream selection to see which of the two inputs ffmpeg will choose.

  use -codec:v copy

  You can also stream copy the video with -codec:v copy. This is probably preferable over re-encoding with -codec:v mjpeg. See stream selection to see which of the two inputs ffmpeg will choose. If you add -map 0 -map 1 then both video streams will be included.

• How do I properly setup and fill a FrameInputNode in VS2017?

  I filled a buffer with audio data and added it to a frame input node which is routed through an audio graph out to a device output node.

  The problem is the audio skips and is at the wrong frequency. I use a key down event to trigger the audio graph to start and never stop the audio graph.

  I followed the code at https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/audio-graphs

  It's pretty much exact, so I'm not sure if their code is wrong, I screwed up the channel counting, or just made a simple mistake.

  The frequency is proportional to the numbers I use though. 1000hz is clearly lower than 2000hz despite the frequencies not being right.

• SAM BROADCASTER CLOUD INTEGRATION With Flutter

• Audio noise measurement with Peak-to-RMS-detection

  I have a question regarding the following piece of code that I found to measure how much noise is included in a piece of audio:

  Sx = fft(x .* hann(length(x), 'periodic')) pk2rms = max(abs(Sx))/sqrt(sum(abs(Sx).^2)/length(Sx))

  This code shall calculate the peak-to-rms ratio of a signal and shall be used to measure the noise that is included in an audio signal.

  As far as I understand, the max(abs(Sx)) calculates the Peak, and the sqrt(sum(abs(Sx).^2) calculates the RMS. But I don't get why this is the case. Why do I first have to apply FFT to calculate the Peak? Isn't the peak just the highest amplitude that is included in a signal? If that was true, I should take do max(abs(x)) without converting the signal into frequency-domain? And why do I have to divide the whole thing by the length of the signal?

  I can imagine that the answers to my questions could be obvious to some of you experts, but I couldn't find proper answers until now.

  Thank you very much in advantage!

• Most efficient way to render bitmap to screen on Linux

  My goal is to receive a video feed from wifi and display it on my screen. For this, I've created a couple of small programs and a bash script to automate them running. It works like this:

  UDPBitmap/Plotter & ffplay -i - < UDPBitmap/pipe & python requester.py;
  

  Translation: There is a C++ program called Plotter, its job is to receive packets on an assigned UDP port, process them and write it to pipe (named: UDPBitmap/pipe). The pipe is accessed by ffplay, and ffplay renders the video on screen. The python file is solely responsible for accessing and controlling the camera with various HTTP requests.

  The above command works fine, everything works as expected. However, the resulting latency and framerate is a bit lower than what I've wanted. The bottleneck of this program is not the pipe, it is fast enough. Wifi transmission is also fast enough. The only thing left is ffplay.

  Question:

  What is the most efficient way to render a bitmap to screen, on Linux? Is there a de facto library for this that I can use?

  Note:

  • Language/framework/library does not matter (C, C++, Java, Python, native linux tools and so on...)
  • I do not need a window handle, but is SDL+OpenGL the way to go?
  • Writing directly to the framebuffer would be super cool...
• dts out of order issue while clipping from m3u8 file

  Ran this command to clip from m3u8 based on start time in seconds and clip duration:

  ffmpeg -i master.m3u8 -loglevel info -bsf:a aac_adtstoasc -vcodec copy -a codec copy -ss 240 -t 60 clip.mp4
  

  Output from the command:

  //reads initial ts files
