• FFMPEG Conversion Options [migrated]

  7 mars 2013, par Mike

  So, I've got some video files I want to convert so they match the formatting on another video file. I've got the format data (from ffprobe) for the video I want to match but I'm not sure how to use that to determine the options to convert my other videos. Any help ?

  Here are the settings on the file I want to match from ffprobe :

      Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'clip #19.mov':

• With ffmpeg, trying to change a container from Mpeg TS to MP4, fps became twice of Mpeg TS

  17 juillet 2016, par user2148481

  I got a Mpeg TS file from a capture board to make a DEMO video clip.

  Here is information of the file from ffmpeg ;

  Stream #0:0[0x51]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 29.97 fps, 59.94 tbr, 90k tbn, 59.94 tbc
  
  Stream #0:1[0x61]: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 224 kb/s

  However, I cannot edit it in FCP X, so I tried to change just its container TS to MP4 with ffmpeg using the below command.

  ffmpeg -i input.ts -vcodec copy -acodec copy output.mp4

  After doing it, fps of output.mp4 became 59.94 fps and information is like below ;

  Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 1750 kb/s, 59.94 fps, 59.94 tbr, 90k tbn, 59.94 tbc
  
  Stream #0:1(und): Audio: mp2 (mp4a / 0x6134706D), 48000 Hz, stereo, s16p, 224 kb/s

  Fps is not same.

  Is there a way to keep same fps as TS with just copy option to change a container ?

  I am wondering whether just re-encoding is solution or not.

• Revision 20babf6d9d : Don't try to use getenv on windows phone/rt The getenv function doesn't exist t

  29 mai 2013, par Martin Storsjo

  Changed Paths :
   Modify /vpx_ports/arm_cpudetect.c

  
  
  Don’t try to use getenv on windows phone/rt

  The getenv function doesn’t exist there. In Visual Studio 2012,
  the function still existed in the link libraries even though
  it was hidden in the headers, but in the 2013 version it has been
  removed from the link libraries as well.
