• FFMPEG HLS multiple Tracks not in sync

  2 juin 2020, par LordFenixNC

  This script works but the video doesnt sync with the sub or audio tracks. Could someone help fix this or Help me with a NEW script. I have been trying to figure this out with 0 luck and have had friends look at it. I even went to FFMPEG discord and FB asking for help from others who have posted scripts in the past. Seems no one has a interest in this. Please will someone help me.

  



  All I am trying to do is BULK encode MKVs to HLS with multiple resoutions in 10 sec segments and include all the Audio and SUb tracks that were originally in the MKV

• Paperclip with heroku and paperclip, migration fails

  2 décembre 2013, par jdartland

  I have a created ruby on rails application and I'm using paperclip to handle my file uploads.
  Paperclip works just fine on my local machine. But my video upload stops working when I deploy to Heroku. Does anyone know whats going wrong. I also get an error when I try to upload a video which says that the video filename does not exist. The photo upload works but not the Video, I'm using paperclip iwth nested attributes and ffmpeg.

  Upload Error log :

• Upper limit on FFMPEG/libx264 frame sizes ?

  22 mars 2014, par Chaotic

  I'm trying to use FFMPEG to transcode a video with very large frames (4096 x 4096). It's a short video - just under two minutes, but the source video file is 15.8GB. (The video is an animation designed to be projected onto planetarium domes.)

  The source file is a Quicktime MOV containing uncompressed Photo-JPEG images (with audio, too). When I tell FFMPEG to transcode my MOV file into an MP4 file, it simply says :

  Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  Not very helpful, but yes, I've verified that all of the parameters are correct and/or defaults. In fact, if I change the requested output size to 2048x2048, then everything works just fine. That's why I suspect that there's an upper bound in the encoder.

  I am kerflummoxed. Any suggestions that result in a successful transcode will be greatly appreciated. (At this point I am also willing to consider alternatives to FFMPEG.)

  The Facts

  I run FFMPEG from a script :

  set srcFile=%1
  
  set dstFile=%srcFile:.mov=.mp4%
  
  
  
  ffmpeg -i %srcFile% -movflags faststart -q:a 0 -q:v 0 -pix_fmt yuv420p -sws_flags gauss -s 4096x4096 %dstFile%
