ffmpeg video stream to app c# [on hold]
3 septembre 2014, par Alexey MedvedevI am trying to make a video mixer for online broadcasts. To do this, I use ffmpeg and C #. I had a problem with the transfer of the video stream from ffmpeg to my program. I would like to receive a stream of ffmpeg using network protocols (e.g. TCP, UDP or others) or capturing if from ffplay window, but I don`t how I can do it. Can you give me some ideas ?
For example, I have command for ffmpeg : "ffmpeg -i video1.mp4 -f mpegts udp:127.0.0.1:5000" or same command with other output formats or network protocols. How i can read video stream from the port and convert it to Bitmap ?
I need to send video stream from my program from computer A to my program to computer B. I write program on C#. I dont know how I can compress video which I must send between my computers and I decided to use Ffmpeg. Now, I can streaming video from my program in computer A to ffmpeg and compress it with parameters which I need.
On second computer I can read this steam using ffmpeg or ffplay, but I don`t know how I can get this stream into my program.
1) How can I get this stream in my program ? Which libraries can you recommend me ?
2) Do you know any libraries which can compress video, instead of using ffmpeg ? -
Error FFmpeg in Android
19 novembre 2013, par MarkI'm using FrameGrabber to load a video from sdcard and perform some image processing operation. I followed the tutorial at JavaCV site to load javacc and ffmpeg.
Currently, to run the application, I'm using my tablet (Asus TF 101G with Android version 4.0.3) connected to my pc and it works fine. But if I try to run the same application in another device (e.g. Nexus with Android 4.1.2) I get these errors :02-01 16:51:54.687: E/AndroidRuntime(2839): FATAL EXCEPTION: main
