• FFMPEG failing to convert mov to flv

  3 mai 2018, par scripter78

  FFMPEG issue that I am not familiar with. seems to only happen with this particular file. Anyone by any chance can take a look at this long out put and provide any feedback on what might actually be causing this ?

  ffmpeg_18.exe -i "E:\TESTFILES\115637.mov" -vcodec libx264 -b:v 700k -s 720x480 -r 29.97 -pix_fmt yuv420p -vf yadif -aspect 4:3 -acodec libvo_aacenc -b:a 96k -ar 44100 -f mp4 -y "E:\TESTFILES\test\115637.flv"

• Remove QTKit dependency

  30 octobre 2014, par Martin Delille

  I want to submint an application using FFMPEG to the Mac App Store but I get rejected because libavcodec links against the deprecated QTKit framework :

  Deprecated API Usage - Apple no longer accepts submissions of apps that use QuickTime APIs.

  I installed ffmpeg using brew install ffmpeg. How can I remove this dependency ?

• Generate fmp4 chunks for HLS with ffmpeg

  11 mai 2018, par genxstylez

  I am trying to generate fragmented MP4 as the chunks for HLS as introduced by apple last year.

  See link -> https://bitmovin.com/hls-news-wwdc-2016/

  Does ffmpeg supports this ?

  Thanks !
