• failed to converted raw H264 to mp4 wiht FFMPEG and playback it

  27 décembre 2015, par Efimk

  I am trying to convert raw video file captured from Cisco EX60 to valid MP4 file.
  I use the following command
  ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 25 -i input2 -vcodec libx264 output2.mp4

  and get

  When I use just
  ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
  It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
  What is wrong with the command ?

• Playback FFmpeg stream through UDP

  11 juillet 2020, par Andrew Raleigh

  I'm using the following command to send ffmpeg data :

  


  ./ffmpeg -i "" -pix_fmt yuv420p -tune zerolatency -preset ultrafast -f mpegts udp://127.0.0.1:23000

  


  I then transmit and receive it to another computer through the srt protocol, and read it back on the end-point.

  


  I play back with .\ffplay.exe -i udp://127.0.0.1:23000 -loglevel 40 and don't see a video. I can see data coming in from WireShark though. This is the log output :

  FFPlay and FFProbe both output the above. Usually FFPlay would show the video playing back, but in this case I get nothing. Any thoughts as to why ?

  


• Encoding a readable movie by QuickTime using FFMPEG

  3 octobre 2014, par itamarb

  I’m trying to encode an image sequence using the following command :

  ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4

  However, QuickTime failed to open this file or sometimes play a black movie, while this movie plays great in VLC player. Any suggestions how to make it play well in QuickTime ?

  Here is the output :

  ffmpeg.exe -i %d.png -f mp4 -vcodec libx264 13.mp4
