• Record F4V in Flash Media Server

  29 juin 2014, par M.Yazdian

  I have problem with record live event in F4v through Flash Media Server
  I publish my live event on FMS though FFMPEG
  FFMPEG Code :

  ffmpeg -f dshow -i video="A4TECH USB2.0 PC Camera" -vcodec libx264 -b:v 32k -acodec libmp3lame -b:a 64k -ar 44100  -f flv rtmp://12.11.1.3/livepkgr/liveevent?adbe-live-event=liveevent

  FMS Code to record F4V file :

  var vodFile = Stream.get("mp4:" + StreamName.name + ".f4v");
  
  vodFile.record();
  
  vodFile.play(streamName,-1,-1);

  So when I use -vcodec libx264 in ffmpeg FMS cam’t to create F4V file, But when I erase -vcodec libx264 from FFMPEG FMS create F4V file currently.

  Please advise me to solve this problem.

• ffmpeg what is the codec for play video in windows media player and web browser

  27 septembre 2016, par Swagat

  I have a requirement to convert video to mp4 which can play both windows medial player(latest version) and web browser(video tag)

  I got to run video in both windows media player or web browser, but two different video. i.e. in below scenario :

  For windows media play, I am using -codec:v mpeg4 and an example is :

  ffmpeg -i input.mp4  -filter_complex  -codec:v mpeg4 -flags:v +qscale -global_quality:v 0 -codec:a libmp3lame  output.mp4

  For Web Browser I need to run with -codec:v libx264 and an example is :

  ffmpeg -i input.mp4  -filter_complex  -codec:v libx264 -flags:v +qscale -global_quality:v 0 -codec:a copy output.mp4

  Both them are working perfectly in their respective player. Even I tried with combine both codec, its obvious, it is raising error.

  Any way to play in both place. Any way of direction will also help me here.

  Thanks in advance.

• Fuji .mov file converted by ffmpeg doesn't play in Windows Media Player [closed]

  30 août 2023, par glipster

  My Fuji X-T3 generates an FHD movie as a .mov with HEVC video and PPM audio. The new Media Player on Windows won't play this (without buying a codec) so I convert it to .mp4 using ffmpeg CLI (ffmpeg -i in.mov out.mp4). The resulting .mp4 file uses AVC video and AAC LC audio. This plays fine in VLC, but will not play in Windows Media Player nor Media Player. I've experimented with various options, but nothing seems to work.
For the original source .mov file, MediaInfo identifies 3 streams :
1stVid : English, 201Mb/s, 1920*1080 (16:9), at 29.970 FPS, HEVC (Main10@L5.2@High)
1stAud : english, 2304 kb/s, 48.0 hKz, 24 bits, 2 channels,PCM (Little/Signed)
1 : QuickTime TC

  


  The Output .mp4 file shows :
1stVid : English 3312kb/s, 1920*1080 (16:9) at 29.970 FPS, AVC (High 10@L4)(CABAC/4 RefFrames)
1stAud : English 132 kb/s, 48.0 kHz, 2 channels, AC LC
1 : QuickTime TC

  


  Using ffmpeg CLI, I tried changing the bitrates for the video and audio, I tried removing the timecode stream, tried a different AAC codec, tried moving the metadata to the front (-movflags faststart), also tried -strict experimental, tried first converting to .mkv (which does work) and then converting to .mp4 (with and without copy). I had hoped one of these might work ; but nothing has worked thus far.

  


  Has anyone else solved this problem ? Any help would be greatly appreciated.
