• Revert "libavcodec/utils.c : simplify avcodec locking with atomics"

  11 décembre 2017, par Hendrik Leppkes

  Revert "libavcodec/utils.c : simplify avcodec locking with atomics"
  This reverts commit 590136e78da3d091ea99ab5432543d47a559a461.
  Atomics are not required for this variable, because it is protected
  
  through the lock manager, and the use of atomics here is not compatible
  
  with the c11 emulation wrappersi.
  Fixes FATE on MSVC, among other setups which use the compat wrappers.

• Pre-Transcoding live streams before Re-stream them to wowza Streaming Engine [on hold]

  14 décembre 2017, par Ninja

  i’am using ffmpeg on other device to get live feed from cam and convert them to multi bitrate outputs localy and stream them to a remote wowza to achieve adaptive bitrate content for users with optimized resources i have succeeded to transcode to one specifique bitrate locally using this line

   ffmpeg -re -i cuted.mp4 -c:v libx264 -profile:v baseline -level:v 1.2 -r 12 -g 96 -vb 110000 -s 212x120 -c:a libvo_aacenc -ab 40000 -ar 22050 -ac 1 -f rtsp -muxdelay 0.1 rtsp://*****:*****@***.168.*0.*0:1935/live/myStream

  but i need at least 4 resolutions support i’ve tried to lunched twice at the same time with diffrent resolutions but in wowza engine manager => incoming streams i got one stream input, i appreciate any suggestion

• ClipBucket video upload and conversion issue

  23 mars 2018, par Aleksandr Levcenko

  I am trying to migrate ClipBucket 2.8.1, RC2, REV 4328 into a new Azure server.
  I managed to install and enable all required modules such as : FFMPEG, PHP CLI, Media Info, MP4Box, ImageMagick and FFProbe.
  Post, Upload, Execution time and Memory limit configuration values have been increased as well on the server side.

  ClipBucket seems to be up and running smoothly, but I have an issue with uploading the videos.
  After uploading a video it shows error message "This video might not work properly".
  When I checked Video Manager it stucks at Processing and does not go any further.

  I tried to delete conversion .loc file but still no luck.

  Can anyone help me with this please ?
