  I use php code:

  $ffmpeg_command ="ffmpeg -i ".$new_name." -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 ".$anew_name;
  $convert_avi = true;
  

  i know that the problem is in here:

  -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5
  

  EDIT2: My ffmpeg info with installed libx264:

• Mingw-w64 builded FFmpeg doesn't show any usage information

  26 octobre 2013, par user1240328

  First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously! The terminal just shows next row. I mean it asks for a next command. But the ffmpeg process is visible in task manager and it writes the output video file what I had requested!

  I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.

  #include 
  #include "cmdutils.h"
  
  const char program_name[] = "hello";
  const int program_birth_year = 2013;
  
  void show_help_default(const char *opt, const char *arg)
  {
      printf("zxcvbnm\n");
  }
  
  int main(int argc, char **argv)
  {
      printf("1234567890\n");
      return 0;
  }
  

  I want to prevent this behavior.

  I want to make printf working in traditional manner.

  How I build FFmpeg:

  PKG_CONFIG_PATH=/home/developer/workspace/MinGW32fs/lib/pkgconfig/ \
  SDL_CONFIG=/home/developer/workspace/MinGW32fs/bin/sdl-config \
  ./configure \
    --prefix=/home/developer/workspace/MinGW32fs \
    --extra-ldflags="-L/home/developer/workspace/MinGW32fs/lib" \
    --extra-cflags="-I/home/developer/workspace/MinGW32fs/include" \
    --arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32-  \
    --pkg-config=pkg-config   --enable-libtheora --enable-libvorbis --enable-libvpx \
    --enable-outdev=sdl --enable-shared --disable-static \

• How to set RTSP mode to TCP using Xuggler

  26 octobre 2013, par Anurag Joshi

  I am working with a Sanyo VCC HD2300P IP camera and trying to capture the frame from the live stream on the camera. I have another camera that provides an rtsp stream and the Xuggler code works fantastically on that. However, on the sanyo camera I get the error below

  could not open stream: rtsp://admin:admin@192.168.0.3:554/VideoInput/1/h264/1
  

  I use this stream on iSpy and VLC and am able to get the stream. Using the functionality from these 2 programs I am also able to capture a frame from the stream. The URL for the other camera that works well is rtsp://admin:123456@192.168.0.246/mpeg4cif. So on the face of it I don't see a reason why it should not work.

  Any help will be highly appreciated.

  EDIT: I searched and experimented a lot. Earlier I was using the inbuilt support for Sanyo cameras in iSpy using which the camera stream was visible. However, when I tried to directly provide the URL for the H.264 stream, the stream would not work unless I changed RTSP mode to TCP. This gave me a hint that probably I need to call the IContainer.open method in a manner that uses RTSP over TCP. Googling about it threw some possible solutions like

  using rtsp://192.168.0.3:554/VideoInput/1/h264/1?tcp
  

  It says that this would force the stream to open on TCP. However, nothing has changed for me. I still get the same error.

  EDIT2: So essentially it boils down to how do I set the RTSP transport mode to TCP? By default the transport mode for RTSP is UDP.
