• ffmpeg failed to pull local rtmp stream

  3 septembre 2019, par edhu

  I’m relatively new to this workflow and this might be a simple problem to solve. However, I haven’t found answers that matched exactly with my question. I’ve set up my nginx server with rtmp module and for testing purposes I used the following command to publish my stream :

  ffmpeg -re -i  -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/show/stream

  After that, I launched up my application which is supposed to read the stream from the nginx server and it failed at

  avformat_open_input(&ctx, szFilePath, NULL, NULL);

  The returned error code is -5 and it signifies I/O issue. The szFilePath I passed in is rtmp://localhost/show/stream and I assume this will automatically work since it works when I tried to play some mp4 sample files online. I also tried rtmp://localhost:1935/show/stream and vice versa. I could view the stream being played in VLC but I can’t open it in the code. I’m not really sure what happened here. I feel like this isn’t necessarily a complicated issue but I don’t know where to start looking for possibles causes. I’d appreciate the help. Thanks !

• facebook friends or birthday video using template and ffmpeg [on hold]

  8 novembre 2017, par Software Development Consultan

  I am working on one feasibility for making application using ffmpeg.

  Application is similar to "facebook friends" video or birthday slice slow video in which different templates facebook show and you can change images and make final video with that template.

  I have checked different options and I can do different filters and slide show from image and videos but I am not getting anything related template using ffmpeg.

  It is possible using ffmpeg ?
  Can someone guide me best way to do this ?

  Thanks

• Decode h264 example ios 7 frame by frame

  18 février 2016, par Андрей Ярядом

  Good day.

  I have a ip camera. From it frame by frame comes stream h264.

  On the Internet, in particular on stackoverflow, a lot of information about how to decode h264 on iOS.
  But this information is not clear.
  I ask you to show me an example and show right direction of how to decode a frame by frame h264 stream to iOS 7.

  What options I have seen and what I know about them :

  • ffmpeg - not suitable for me, as it has LGPL license.

  • AVAnimator library - license inappropriate for me.

  • Hardware decoder - the best solution, but as I understand it, is only
    available for iOS 8.

  For me to be the perfect option if you give me an example for correct decoding h264 stream and display it on the way to the screen.

  Regards.
