• ffmpeg wrong framerate when converting x264 to x265

  11 April 2023, by Andreas

  I want to convert the video files from my Samsung phone to a more efficient format. Samsung uses x264 with a very high bitrate, instead I am using x265 with the following settings:

  


  ffmpeg -i IN.mp4 -c:v libx265 -c:a copy -x265-params crf=25 OUT.mp4


  


  However, there seems to be a problem with the framerate. Samsung specifies 60 fps in the metadata, but the video stream shows 29.95 fps.
If I use the above command to convert to x265, it even outputs a stream with 120 fps. ffmpeg also shows the warning "More than 1000 frames duplicated".

  


  How can I keep the original framerate?

  


  Here is the ffmpeg output:

  


  ffmpeg -i IN.mp4 -c:v libx265 -c:a copy -x265-params crf=25 OUT.mp4

• Cropping a video from Sony A7 Camera using ffmpeg

  23 October 2023, by Mike Slinn

  I want to crop a video file created by a Sony A7iii camera, so only the portion from 0:51 through 2:45 is extracted.
The camera adds streams that need to be ignored.

  


  ffprobe shows the error on input stream 2, however the problem I am reporting deals with input stream 3, which is a data stream, and is not required. I want to exclude input stream 3, then deal with input stream 2.

  Predictably, ffmpeg fails because ffprobe failed.

  I tried various incantations that specified permutations of -map options, but only dug myself a deeper hole.

  


  How might I perform the extraction? I am not interested in preserving extra streams, I just want the main video and stereo audio streams.

  


• Using Video Recordings in Vuforia ARCamera

  2 July 2023, by Chengyuan Qian

  I am trying to test Vuforia on some pre-recorded videos in a Unity project. However, I found that I can only use videos recorded by the Vuforia SessionRecorder. When I use video recorded by other apps or devices, even though its resolution, frame rate and encoding type are all the same as the Vuforia's sample recordings, I still get the following error,

  


  Failed to start Vuforia

  In addition to make sure the resolution, frame rate and encoding type the same, I used ffmpeg to check the metadata of Vuforia SessionRecorder's recordings and my own recordings, but I have no idea which property makes the difference. Below are the metadata of the two videos,
