• ffmpeg error "No such file or directory" while compiling a video file compression

  13 janvier 2016, par Abraham Gharyali

  Firstly I have checked many questions and answers related to my question, but unfortunately none of them solves my problem.

  I have implemented ffmpeg library in my project, using it for 2 tasks :

  1). adding watermark on video.

  2). video compression.

  I am able to apply watermark on recorded video successfully using this command :

  {"-y" ,"-i", "/storage/emulated/0/Booms/Videos/video1122150738.mp4","-strict","experimental", "-vf", "movie="
  
  + watermarkFile + " [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s", "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/storage/emulated/0/Shared/Videos/video.mp4"}

  "watermarkFile" is the location of .png watermark file

  Now I need to compress video, for that i used this command :

  "ffmpeg -i "+"/storage/emulated/0/Booms/Videos/video1122150738.mp4"+" -vcodec mpeg4 -s 320x240 -r 25 -y "+"/storage/emulated/0/Shared/Videos/video.mp4";

  It gives error "No such file or directory". please see the logs.

  for both operations i input .mp4 file and need .mp4 file in output.

  Same process works for watermarking and not working for compression.

  My compress command is correct because I checked the same command compressing video in my windows pc using command prompt.

  I don’t understand what i am doing wrong.

  Any help would be appreciated.

• Live555 : X264 Stream Live source based on "testOnDemandRTSPServer"

  26 octobre 2017, par user2660369

  I am trying to create a rtsp Server that streams the OpenGL output of my program. I had a look at How to write a Live555 FramedSource to allow me to stream H.264 live, but I need the stream to be unicast. So I had a look at testOnDemandRTSPServer. Using the same Code fails. To my understanding I need to provide memory in which I store my h264 frames so the OnDemandServer can read them on Demand.
