  • Live video streaming using progressive download (and not RTMP) in Flash

  I am using ffmpeg to create an mp4 file on my server. I am also trying to use qt fast start to be able to move the moov atom to the front so it will stream. I have searched all over the internet with no luck. Is it possible to put my video/audio in a mp4 buffer type file and then be able to play it while ffmpeg is still dumping video and audio data into the stream ? the point is I am trying to stream from a camera and Android is horrid... I know both ios and android support mp4 so I was trying to figure a way I can make my rtsp Mp4.

  main point of the story : I want to continuously feed my mp4 container my camera feed and still be able to playback the file os my clients can watch.

  any help appreciated thank you.

• How to remove video background with ffmpeg ?

  22 juillet 2022, par Billi Alt

  Is there a way in ffmpeg-python to remove a single colored green screen background and to replace it with another video ?

  


  So I have a video "test.mp4". It is basically a man talking in front of a green screen. I would like to add multiple background videos. One from second 0-5 the next from second 5-15 and so on.

  


  The green screen is only one color so no shadows or anything else just one single green color. Is there a way to remove the green screen in ffmpeg-python or an other python library ?

  


• Ffmpeg c++ can't compile with libxh264

  10 septembre 2022, par Turgut

  I made a program that uses the source version of ffmpeg. I get the code from it's website and compile/configured it. The problem is I want to configure it with the libx264 flag so it looks like this :

  


  ./configure --enable-shared --enable-libx264 --enable-gpl


  


  Ffmpeg itself compiles with no errors, however when I try to compile my own code using make I get this error :

  (The error is a bit longer but I think this is ample for now.)

  


  The thing is, this code also runs on the cloud and compiles just fine without the --enable-libx264 flags. And inside the cloud, it works just fine even with the libx264 flag. But when I follow the exact same steps as the cloud and try to compile it locally, it gives this error.

  


  Here are the steps I have followed :

  


  First I removed ffmpeg (It was a bit messy) using sudo apt-get --purge autoremove ffmpeg then I made sure its deleted by searching find / -name ffmpeg and manually deleting my findings. Then, I ran apt-get install -y libx264-dev, followed by ./configure --enable-shared --enable-libx264 --enable-gpl inside the directory where I have downloaded the source files. Then ran make and make install where ffmpeg source files are. I ran ldconfig so it can detect shared libs (This is how it works on the cloud) and finally ran make on my own codes directory and got the error mentioned.

  


  Here is my CMakeFile :

  Like I said, it works on the cloud just the way it is and everything works without the --enable-libx264 flag.

  


  How can I fix this ? I'm on ubuntu 22+
