• 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 ?

• Android studio + OpenCV + FFmpeg

  11 juillet 2018, par t0m

  I have problem with code, which is functional only for Genymotion device (Android 4.1.1), but for Genymotion device 5.0.1 and real device Huawei honor 4c Android 4.4.2 not.

  I have imported OpenCV 3.1 to Android studio by : https://stackoverflow.com/a/27421494/4244605
  I added JavaCV with FFmpeg by : https://github.com/bytedeco/javacv

• 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.
