• ffmpeg ignores every framerate option, locking the result to 25 fps

  1er août 2023, par Goury

  ffmpeg version 3.4.8-0ubuntu0.2 Copyright (c) 2000-2020 the FFmpeg developers

  


  No matter what I do, ffmpeg just ignores everything and encodes it as if it's 25fps.
  
-framerate 60 does nothing
  
-t 60 does nothing
  
-r 60 makes it to interpolate frames
  
-r:v 60 does the same
  
-vf "fps=60" does the same
  
-vframes <actual number="number" of="of" frames="frames"></actual> makes it to end the encoding prematurely

  


  Everything google shows seems to be outdated, including ffmpegs own documentation

  


• FFMPEG muxed as a private data stream and may not be recognized upon reading

  4 mars 2021, par Jimmy

  I've came across a mkv with a codec of hevc , while trying to either convert it to m3u8 or mp4 I received this following message :

  


  [mpegts @ 0x7f94de014600] Stream 1, codec flac, is muxed as a private data stream and may not be recognized upon reading.

  


  Is there something wrong with my ffmpeg parameters ?

  


  To m3u8 :
#1 :

  


  ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8


  


  #2 :

  


  ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -c:v libx264 -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8


  


  To mp4 :

  


  #1 :

  


  ffmpeg -i aaa.mkv -c copy ccc.mp4


  


  #2 :

  


  ffmpeg -y -i aaa.mkv -codec copy -strict -2 ccc.mp4

• Transcoding with the GCP Transcoder API results in a time gap

  3 mars 2021, par banyan

  I've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.

  


  The specific cases are as follows :

  


  

  1. Specifying startTimeOffset and endTimeOffset (cut off 2 seconds before and after the video)

  


  2. fMP4 is used as container

  


  3. input video is mp4 with screen recording on iPad Pro

  


  


  For example, if I don't specify startTimeOffset and endTimeOffset, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

  


  I'm not sure whether this is a problem with the Transcoder API or with me.

  The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected : 00:02:47.00, actual : 00:02:45.00) In this case, it's a 2-second gap, but it can be 10 seconds or 30 seconds, and it varies from video to video.
