I want to get audio bitrate from video file and save it.
Is it possible to get audio track bitrate alone form video file using ffmpeg ?
if possible then how to do it?...Any suggestion will be appreciated.
I am using the media muxer on Android to create an mp4. Basically I am feeding bitmaps to the muxer and encoding each bitmap as 1 second of video. Everything is working fine except that the last frame of video (the last bitmap) flashes at the very end of the video but doesn't also hold for 1 full second. This occurs when sharing to instagram, hangouts etc but if I pull the mp4 up on my mac it plays the full final second. Does anyone know what may be causing this? I am using this implementation:
How to encode Bitmaps into a video using MediaCodec?
I made a video player by TextureView and Mediaplayer. And I want to capture current frame. I found some questions about this. But They deal with capturing video from local video file. But I need capturing current video frame from streaming video. How can i do this?
Thanks!
I am creating a video streaming app which uses a IP Camera as external device.
I can already get the image (.cgi format) from the ip url of the device(192.168.x.x/image/image.cgi). I can update the image view every several milli seconds to update its content and its working great, no issues there.
The question is, can I save this bitmaps as video (.mp4)? I tried MediaRecorder before and works, is there a way to do that on streaming bitmaps ?
thanks
The "video" is a stream of jpeg images.

for some java code that displays such images. You need to transcode the images to a different format. E.g. on the command line that can be done with

Doing this on android has been discussed at how to save the mjpeg stream as 3gp or mp4 format video files to the sdcard in android
googling for mjpegstream video convert gives you more results ...
I need to capture the video and video save to the sd card using hardware.camera class.
I created sample application with Camera.callback. It work fine. But saved video not working.
I saved the file in 3gp format. Each byte array added to a single byte array.And it saved to 3gp format.But it is not working.
After i substitute the header and footer portion 3gp in to that file. But it is not working. what i do to record video in this way(hardware.camera)?
The Android MediaRecorder class handles recording video withough having to implement the camera callback. It is capable of saving files in the 3GP format
