• Video filters are ignoring -noautorotate

  23 juillet 2021, par chemdrew

  I’m noticing that -noautorotate is not being accounted for by the video filters. This is apparent with a rotated video input and grabbing a thumbnail from it using the video filters.

  


  Tried it with a couple different commands, with the same results :

  


  ffmpeg -noautorotate -i  -f mp4 output.mp4 -vframes 1 thumbnail.jpg

  


  ffmpeg -noautorotate -i  filter_complex split=1[screen0] -f mp4 output.mp4 -vframes 1 -map [screen0] thumbnail.jpg

  


  The output.mp4 is output without following the rotation metadata, but the thumbnail.jpg is output following the rotation metadata.

  


  I would expect that with the -noautorotate flag on the input it would also honor that when applying the filters to the input.

  


• ffmpeg can not open video file while PotPlayer and VLCPlayer can

  13 décembre 2020, par popova-ksiusha912

  Win10

  


  Video file(21.83MB) :https://www.mediafire.com/file/7b7w8ssio32qo2p/sample.flv/file

  


  Pot Player and VLC Player can open this file without any problem.

  


  But ffmpeg,ffplay,ffprobe can not open it.

  


  Is there any way to make ffmpeg recognize this video file ?

• Merge commit ’fca3c3b61952aacc45e9ca54d86a762946c21942’

  31 janvier 2017, par Clément Bœsch

  Merge commit ’fca3c3b61952aacc45e9ca54d86a762946c21942’
  * commit ’fca3c3b61952aacc45e9ca54d86a762946c21942’ :
  
    hevc : Add AVX2 DC IDCT
  Mostly noop as we already have that code.
  In the ASM, code is merged with the exception of SECTION which is kept
  
  uppercase for consistency with the rest of the codebase.
  Still in the ASM, the prototype comment is fixed to honor the ’_’ added
  
  from the original commit.
  idct_dc_proto() is dropped as it’s not used anymore here.
