• Windows video player cannot play cropped video from ffmpeg

  28 juillet 2019, par Chen Clarence

  I am trying to crop video with ffmpeg, I have encountered three problems.
  First, I used the following code to crop a 1080p video.

  ffmpeg -i 1080vid.avi -vf "crop=1920:1080:0:0" -c:v libx264 -crf 1 -c:a copy output.mp4

  However, in the compression rate argument, it only works if I set -crf to a positive value. If I set it to 0, then the output video cannot be played by my Windows 10 video player. However, since I am pursuing a lossless conversion, this is problematic. The output mp4 is smaller than 5% of the original size.

  The original goal was to cut a 1080*15360 video into 8 1080p videos. However, using the following code, I get unplayable output after playing with all the settings.

  ffmpeg -i sample.avi -vf "crop=1920:1080:0:0" -c:v libx264 -crf 1 -c:a copy output.mp4

  The input sample.avi is a lossless avi with bitrate larger than 1GB/s, and the output is a 70kb unplayable file. When opened, a pop up window displays :

  Choose something else to play. This item is in a format we don't support.
  
  0xc00d36b4

  The following is the command line output.

• Using ffserver to stream older IP cam MJPEG to RTSP

  26 mai 2016, par tmar89

  I have an older Sony IP camera that has an MJPEG stream. I need to connect this to an NVR that only takes ONVIP or RTSP and I’m trying to use ffserver and ffmpeg to convert the MJPEG stream to RTSP but it’s not working. Any have some idea of what I may be doing wrong ? Saw an error in the attempted playback about an unsupported Protocol.
  Here is my ffserver config :

  Port 8090
  
  RTSPPort 5544
  
  BindAddress 0.0.0.0
  
  RTSPBindAddress 0.0.0.0
  
  MaxClients 100
  
  MaxBandwidth 10000
  
  
  
  <feed>
  
  File /tmp/feed27.ffm
  
  FileMaxSize 5M
  
  ACL allow 127.0.0.1
  
  </feed>
  
  
  
  <stream>
  
  Format rtp
  
  Feed feed27.ffm
  
  NoAudio
  
  VideoCodec mjpeg
  
  VideoFrameRate 30
  
  VideoSize 736x480
  
  </stream>

  And here is the ffmpeg command I am using :

  [tm@tele ffserver-rtsp]# ffmpeg -f mjpeg -r 30 -s 736x480 -i http://[CAMIP]/image http://localhost:8090/feed27.ffm

• omxplayer freezes with videos generated with FFMPEG

  31 décembre 2020, par Chocksmith

  Omxplayer won't play any videos generated with FFmpeg on a Raspberry Pi

  


  I found this thread showing that it is necessary to include '-profile baseline -level 3.0' parameters : https://github.com/popcornmix/omxplayer/issues/577

  


  The full command is :

  


  ffmpeg -framerate 1/10 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p -profile baseline -level 3.0 images.mp4


  


  I did that and now I am experiencing intermittent behavior.

  


  Sometimes it works and sometimes it does not work. I cannot explain why/when it plays or not.

  


  I also found a thread showing that it is necessary to upgrade the firmware and player. I did that and still having the same issue.

  


  Here is an example. First time it plays ok. Second time it freezes.

  


  First time : creating mp4
