• ffmpeg/libx264 C API : frames dropped from end of short MP4

  19 juillet 2017, par Blake McConnell

  In my C++ application, I am taking a series of JPEG images, manipulating their data using FreeImage, and then encoding the bitmaps as H264 using the ffmpeg/libx264 C API. The output is an MP4 which shows the series of 22 images at 12fps. My code is adapted from the "muxing" example that comes with ffmpeg C source code.

  My problem : no matter how I tune the codec parameters, a certain number of frames at the end of the sequence which are passed to the encoder do not appear in the final output. I’ve set the AVCodecContext parameters like this :

  //set context params
  
  ctx->codec_id = AV_CODEC_ID_H264;
  
  ctx->bit_rate = 4000 * 1000;
  
  ctx->width = _width;
  
  ctx->height = _height;
  
  ost->st->time_base = AVRational{ 1, 12 };
  
  ctx->time_base = ost->st->time_base;
  
  ctx->gop_size = 1;
  
  ctx->pix_fmt = AV_PIX_FMT_YUV420P;

  I have found that the higher the gop_size the more frames are dropped from the end of the video. I can also see from the output that, with this gop size (where I’m essentially directing that all output frames be I frames) that only 9 frames are written.

  I’m not sure why this is occurring. I experimented with encoding duplicate frames and making a much longer video. This resulted in no frames being dropped. I know with the ffmpeg command line tool there is a concatenation command that accomplishes what I am trying to do, but I’m not sure how to accomplish the same goal using the C API.

  Here’s the output I’m getting from the console :

• Monit not restarting ffmpeg live stream when disconnected

  21 juillet 2017, par digibread

  No matter what I try I cannot get Monit to restart my ffmpeg live stream even though my bash script works from the command line. I start the ffmpeg live stream and all is working. Monit status shows that is ffmpeg is running. I then reboot the camera and the connection is lost, Monit tries to start it with the log file entries below. the config files.
  Here is my setup. Any help is greatly appreciated.
