• Vagrant provision fails to execute the next script without an obvious reason why

  14 juin 2016, par JakeTheSnake

  I’ve created/co-opted several bash scripts to provision my guest Ubuntu 14.04 OS ; the one giving me trouble right now is installing ffmpeg. When the script finishes, vagrant simply does nothing save for sending SSH keep-alives.

  Host OS : Windows 7 x64

  The last output before the infinitely repeating keep-alives is :

  INSTALL libavutil/sha.h

  I won’t include the other scripts for the sake of brevity. When logging into vagrant with the gui nothing seems out of the ordinary, and ffmpeg is available...but nothing else is provisioned. No RVM, no Nginx, nothing.

• ffmpeg mp4 upload to Twitter - Unsupported Error

  13 juin 2016, par Noitidart

  I have created a screencast, it was saved as webm. Using ffmpeg I converted it to a mp4 :

  That kind of file isn’t supported yet. Try uploading a gif, video, or picture instead.

  ffmpeg -f input.webm -pix_fmt yuv420p -strict -2 output.mp4

  I use yuv420p as that is what this topic says for twitter - https://twittercommunity.com/t/unable-to-upload-video-to-twitter/61721/3

  However when I open a new tab, go to twitter, click the photo icon, clicking upload instantly gives me error "That kind of file isn’t supported yet. Try uploading a gif, video, or picture instead.". It cant check the pix format that fast. Anyonek now what can be going on here ?

  Here is ffmpeg console output :
