• ffmpeg - cut without reencoding and strange behaviour : application provided duration is out of range for mov/mp4 format [closed]

  27 août 2023, par user2707175

  In Ubuntu 18.04 I quite often used the following command for trimming part of the video without re encoding (which means without any quality loss).

  


  ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c copy DSCF5984_A_wszystkie.MOV

  


  Not so much time ago I moved to Ubuntu 22.04. Still having the same video camera and still using the same format for recording, when using the command as above I'm getting quite strange error and the behavior is unexpected. In this case mov file is 40 sec file. I want to get 7 seconds fragment starting from 6 second (thus from 6 to 13 sec). Instead of this I get very short fragment from the beginning of the file. I don't even know how long as none of video players want to display its length. Probably it's 1-2 sec. Thus it's not only, I get this error, but ffmpeg doesn't work. In theory I have the newest version available for ubuntu 22.04.

  Is that some kind of error ? Or should I do sth different ? I'm quite surprised as I didn't change my camera. So is that sth changed in ffmpeg ?

  


• ffprobe newer version detect audio codec incorrectly

  16 janvier, par alancc

  I find a strange problem.

  


  I have a test video with h264 video codec and aac audio codec. It is at https://drive.google.com/file/d/1YAyz5cO0kb9r0MgahCpISR4bZ_1_n8PL/view?usp=sharing

  


  I build a ffmpeg version by myself, its version is :

  


  ffprobe version 7.0.2 Copyright (c) 2007-2024 the FFmpeg developers
  built with gcc 14.1.0 (Rev3, Built by MSYS2 project)
  configuration: --enable-shared

  libswscale      8.  1.100 /  8.  1.100
  libswresample   5.  1.100 /  5.  1.100


  


  I then use ffprobe to get its info :

  


  ffprobe -v quiet -print_format ini -show_streams -show_packets test_h264.mp4 > test_h264.ini


  


  Then I get an ini file which shows the audio codec as MP2 :

  


  [streams.stream.0]

  Another developer he uses his version of ffprobe :

  


  ffprobe version 2023-02-22-git-d5cc7acff1-full_build-www.gyan.dev Copyright (c) 2007-2023 the FFmpeg developers  


  


  Based on the year, my version(2024) should be newer than his(2023), but his version of ffprobe can get the audio codec properly :

  


  [streams.stream.1]
index=1
codec_name=aac
codec_long_name=AAC (Advanced Audio Coding)

  Why ?

  


  I also tried a ffprobe version on ubuntu with the following version :

  It will detect the audio as aac properly, but with different parameters, for example, bit_rate is 111733(developer) but 110399(ubuntu). But this parameter comes from the same file so should be the same.

• ffmpeg wrong framerate when converting x264 to x265

  11 avril 2023, par 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
