• Remove Unwanted Rotation of video when merge audio With Video Using FFMPEG

  2 octobre 2015, par bhavesh kaila

  Actually I want to overwrite Audio Using Recorder Audio file into Recorded Video File.For That I am Using FFMPEG Library Project from this Link

  Issue :
  When I capture video in Portrait mode and then merge video with recorded audio merging is working fine but the problem is Video is rotate 90 Degree and then merging is work.I don’t Want to rotate video I want to do merge Only.

  if I capture video in Landscape Mode Then Merging audio is Working Fine.

  Below Currently FFMPEG Command is Used for merging Audio with Video File

  ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0 OutputFile.mp4

  And I Have Tried Using Below Commands also but it’s Not working

  ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 rotate=0 OutputFile.mp4

  And

  ffmpeg -y -i Video.mp4 -i Audio.mp4 -c:v copy -c:a copy -strict experimental -map 0:v:0 -map 1:a:0  -vf -metadata:s:v:0 translate=1 OutputFile.mp4

  And I have Trying othe possibility also but its not work for me.

  Any Help Would be Acceptable.

  Thanks In Advance

• ffmpeg hangs when run in a multi-threaded environment

  3 février 2018, par Zaid Amir

  I have a service that needs to transcode large amount of videos with different formats. The service spawns five threads, one for a single video and each thread runs ffmpeg with the following command :

  ffmpeg -i %%FILEPATH%% -vf scale=X:Y -ab 128k -c:a aac -movflags faststart -strict -2 -ar 22050 -r 24 -c:v libx264 -crf 25 -y %%OUTPUT.MP4%%

  where X and Y are the desired dimensions based on the orientation of the original file basically its either 640:trunc(ow*a/2)*2 for landscape or trunc(oh*a/2)*2:640 for portrait.

  This is my ffmpeg info :

  I am currently spawning five threads, and each thread runs a single instance of ffmpeg targeting a single video file.

I noticed from top that ffmpeg hangs indefinitely on some files with one of the threads using 100% of the core CPU and no progress is made. It happened with different file types as I noticed this on mkv, avi, wmv and mp4 files.

  I am not sure what is causing ffmpeg to hang, it does not happen right at the beginning of the transcoding process, ffmpeg starts converting the file fine but somewhere in the middle it gets stuck.

  Now this is not a problem with the files as when I try the same command on the same file manually it runs fine. And it only seems to happen when there are multiple instances of ffmpeg running at the same time as I now changed my service to only run a single thread and it has been running for almost a month with no issues.

  Is there an option that I need to use to allow multiple instances of ffmpeg to run at the same time ? Is it something in the command line that I currently use that causes this ?
