  • Is there a media server which just receives any rtsp streams and serves them ?

    7 mai 2015, par Given92

    I have some rtmp streams served over nginx-rtmp-module and the number of them will be changed dynamically.

    But for the limit of client, I have to serve them in rtsp protocol. Obviously, It’s not supported by nginx-rtmp-module. So I plan to run a rtsp server in the same device, and convert the rtmp stream into rtsp stream with ffmpeg, then send the rtsp stream to the rtsp server. So that client could play the stream from the rtsp server.

    The trouble is that I could not found a stable server which just receive any rtsp streams and serve them.

    There is an example that fits all my need but it’s a little unstable.

    I run it in verbose mode and send stream with :

    ffmpeg -i rtmp://localhost/<name> -codec copy -ar 44100 -ac 1 -f rtsp rtsp://localhost:5545/<name>
    
</name></name>

    and play the stream with :

    gst-launch-0.10 playbin2 uri=rtsp://<server>/<name>
    
</name></server>

    The video does not appear and there are some repeated warnning like this :

    WARNING: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0: Could not decode stream.
    
Additional debug info:
    
gstrtpvorbisdepay.c(633): gst_rtp_vorbis_depay_process (): /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstRtpVorbisDepay:rtpvorbisdepay0:

    When I try :

    gst-launch-1.0 playbin uri=rtsp://<server>/<name>
    
</name></server>

    it is stuck and no video appear :

    The video appears but the quality depress me.

    I’m not sure whether ffmpeg or rtsp-server is the problem, does anyone have some ideas ?

    Thanks very much.

  • No such file or directory Error with FFMPEG screenshot and CarrierWave custom model method

    9 juillet 2013, par dodgerogers747

    I am using AWS CORS to upload videos to my site, all of which works as planned.

    I have the following model method which runs as an after_create callback (for speed) to take a screenshot from the video file on AWS. I plan to move this out into a delayed job but I don't think this will solve this particular issue. Please advise if mistaken.

    I use FFMPEG to take a screenshot from the AWS self.file location, I then send the file to CarrierWave by saving the file to self.screenshot where it is uploaded to AWS.

    Approx. 50% of the time it errors out with Errno::ENOENT - No such file or directory for the location of the screenshot image.

    How can I rectify my code to remove this error and how come it only occurs around 50% of the time ? If anyone needs more code just shout.

    video.rb

    after_create :take_screenshot
    

    
mount_uploader :screenshot, ImageUploader
    

    
  def take_screenshot
    
    location = "#{Rails.root}/public/uploads/tmp/screenshots/#{unique}_#{File.basename(file)}.jpg"
    
    system `ffmpeg #{log_level} -i #{self.file} -ss 00:00:0#{time_frame} -vframes 1 #{location}`
    
    logger.debug "Trying to take screenshot from #{self.file}"
    
    #pass the actual file to CarrierWave to handle the image upload
    
    self.screenshot = File.open(location)
    
    self.save
    
    logger.debug "Deleting tmp file: #{location}: #{File.delete(location)}" if self.screenshot.present?
    
  end
    

    
def unique
    
    (0..6).map{(65+rand(26)).chr}.join
    
  end
    

    
def log_level
    
    "-loglevel panic"
    
  end
    

    
  def time_frame
    
    rand(0..3)

  • Get frame from live video stream

    10 avril 2013, par rickster

    I am streaming live video from my camera on my android phone to my computer using the MediaRecorder class.

    recorder.setCamera(mCamera);
    
recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
    
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);          
    
recorder.setOutputFile(uav_UDP_Client.pfd.getFileDescriptor());                     
    
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);

    That's the basic idea. So I would like to show this stream in real time. My plan is to use FFMpeg to turn the latest frame into a .bmp and show the .bmp on my C# program every time there is a new frame.

    The problem is there is no header until I stop the recording. So I can not use FFMpeg unless there is a header. I've looked at spydroid and using RTP but I do not want to use this method for various reasons.

    Any ideas on how I can do this easily ?
