• avcodec/libx264 : Set min build version to 158 for msvc

  9 juin 2022, par Matt Oliver

  avcodec/libx264 : Set min build version to 158 for msvc
  Was "[PATCH] libx264 : Do not explicitly set X264_API_IMPORTS"
  Setting X264_API_IMPORTS only affects msvc builds and it breaks
  
  linking to static builds (although is required for shared builds).
  
  This flag is set by x264 in its pkgconfig as required since build
  
  158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019.
  
  So this patch updates configure to require a newer x264 build that
  
  correctly sets the imports flag.
  The min version requirement of 158 is applied for msvc builds only.
  This is also removing the check for 'libx264 without pkg-config'
  
  which was left for compatibility reasons about 7 years ago when
  
  the pkg-config check was introduced by commit
  
  e06263ef1e0e172b2c76070b3dc739411af08e82.

• How to convert a video to be compatible with facebook graph (reel) api

  25 mai 2023, par Micha

  I am currently trying to get this api to work : create user media

  


  Everything works if I try to post photos. But as soon as I try to post a reel I always get the same error :

  


  {&#xA;  "error": {&#xA;    "message": "The video file you selected is in a format that we don&#x27;t support.",&#xA;    "type": "OAuthException",&#xA;    "code": 352,&#xA;    "error_subcode": 2207026,&#xA;    "is_transient": false,&#xA;    "error_user_title": "Unsupported format",&#xA;    "error_user_msg": "The video format is not supported. Please check spec for supported streams format",&#xA;   "fbtrace_id": "<removed>"&#xA;  }&#xA;} &#xA;</removed>

  


  So I look into the reel specifications here : reel specification

  


  Try as I might, I cannot get it to work. I work with technical google searches all day long, yet this time I seem to be looking in a completely wrong direction.

  


  I have tried converters like Any Video Converter.

  


  I have tried ffmpeg with the following command : ffmpeg -i input.mp4 -c:v libx264 -aspect 16:9 -crf 18 -vf "scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:(1280-iw)/2:(720-ih)/2" -fpsmax 60 -preset ultrafast -c:a aac -b:a 128k -ac 1 -pix_fmt yuv420p -movflags +faststart -t 59 -y output.mp4

  


  If there is a solution with ffmpeg I would appreciate it as I could automate much of the process. But if you know of any converter software I would gladly take that as well.

  


  I think the main problem is the container requirement MPEG-4 Part 14. I can't seem to find any software that is able to produce a video with the required format. The closest I have gotten is MPEG-4 Part 10 but that doesn't work with the api.

  


  Any help would be greatly appreciated.

  


• Output of ffmpeg into HDFS directly

  1er juillet 2016, par Maddy

  I have a requirement in which I have to convert a RTSP stream into mp4 video or frames (as the case may be) & want to save them in HDFS (Hadoop Filesystem).

  For this I have tried using ffmpeg to convert the RTSP stream into mp4 video/frames & saving the video/frames in local filesystem. Like below -
  ffmpeg -i rtsp://10.0.37.150:8554/big_bunny.mkv -r 1 -f image2 frames/big_frame-%3d.bmp
ffmpeg -i rtsp://10.0.37.150:8554/big_bunny.mkv big_bunny.mp4

  And then saving the video/frames (stored in local filesystem) into hdfs using put command -
  hadoop fs -put frames/ /user/maddy/
hadoop fs -put big_bunny.mp4 /user/maddy/

  This is working. But I want to do this directly (that is in one step without saving the required files in local filesystem)

  I tried something (like below command) but it is not working
  ffmpeg -i rtsp://10.0.37.150:8554/big_bunny.mkv hdfs://localhost:9000/user/maddy/big_bunny.mp4

  I get this error -
  hdfs://localhost:9000/user/maddy/big_bunny.mp4: Protocol not found

  So is there any way in which using ffmpeg I can directly save these files into hdfs without first saving in my local filesystem.
  Or is there any other tool through which I can achieve this ?

  EDIT :

  Tried ffmpeg -i rtsp://10.0.37.150:8554/big_bunny.mkv - | hadoop fs -put - /user/maddy/
  as suggested by @incBrain

  But received this error -
