Android Get only Audio Stream of Online Video ?
19 avril 2014, par user1575044I am beginner in Android, basically I want to get only audio stream of an online streaming video, so that I don't have to download video just download audio part of video only as an mp3 file(saving lot of data if you only need it as an mp3 file). I researched and got to know it can be done maybe using ffmpeg. Can someone guide me in this, some tutorials links or sample code would be beneficial.
Thank You !!

Streaming webcam using ffmpeg and ffserver
24 octobre 2012, par gazzwi86I'm using a Logitech C270 webcam and a Raspberry Pi and attempting to stream an audio and video feed to my mac. I've tried this quite a number of ways and now managed to get a video feed using mjpeg-streamer, however, this does not support audio.
I was wondering if anyone could explain where I have gone wrong with my ffmpeg configuration. I am trying to stream /dev/video0, and if possible would like to do away with mjpeg-streamer so that I can use just one tool for the full task.
ffmpeg installation

FFMPEG options for video streaming
26 février 2014, par YorgZI am trying to use ffmpeg to stream video using ffserver. You will find below the ffserver1.conf file, and the log output from the ffmpeg command.
One of the errors references presets, and everytime I try to use presets I get the error "File not found, even after copying all the preset files in the current directory.
Thanks for the help.
