Rotating videos with FFmpeg

Question

I have been trying to figure out how to rotate videos with FFmpeg  I am working with iPhone videos taken in portrait mode  I know how to determine the current degrees of rotation using MediaInfo  excellent library  btw  but I m stuck on FFmpeg now   From what I ve read  what you need to use is a vfilter option  According to what I see  it should look like this   ffmpeg -vfilters  rotate 90  -i input mp4 output mp4   However  I can t get this to work  First  -vfilters doesn t exist anymore  it s now just -vf  Second  I get this error   No such filter   rotate  Error opening filters    As far as I know  I have an all-options-on build of FFmpeg  Running ffmpeg -filters shows this   Filters  anull            Pass the source unchanged to the output  aspect           Set the frame aspect ratio  crop             Crop the input video to x y width height  fifo             Buffer input images and send them when they are requested  format           Convert the input video to one of the specified pixel formats  hflip            Horizontally flip the input video  noformat         Force libavfilter not to use any of the specified pixel formats  for the input to the next filter  null             Pass the source unchanged to the output  pad              Pad input image to width height  x y  color    default x and y   0  default color  black   pixdesctest      Test pixel format definitions  pixelaspect      Set the pixel aspect ratio  scale            Scale the input video to width height size and or convert the i mage format  slicify          Pass the images of input video on to next video filter as multi ple slices  unsharp          Sharpen or blur the input video  vflip            Flip the input video vertically  buffer           Buffer video frames  and make them accessible to the filterchai n  color            Provide an uniformly colored input  syntax is   color  size  ra te    nullsrc          Null video source  never return images  nullsink         Do absolutely nothing with the input video    Having the options for vflip and hflip are great and all  but they just won t get me where I need to go  I need to the ability to rotate videos 90 degrees at the very least  270 degrees would be an excellent option to have as well  Where have the rotate options gone

For me it works like this

Rotate clockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=1" "path_output_video.mp4"

Rotate counterclockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=0,transpose=1,transpose=0" -acodec copy "path_output_video.mp4"

the package I use zeranoe

An additional solution with a different approach from the last mentioned solutions  is to check if your camera driver support the v4l2 camera controls  which is very common    In the terminal just type   v4l2-ctl -L   If your camera driver supports the v4l2 camera controls  you should get something like this  the list below depends on the controls that your camera driver supports                   contrast  int       min 0 max 255 step 1 default 0 value 0 flags slider              saturation  int       min 0 max 255 step 1 default 64 value 64 flags slider                     hue  int       min 0 max 359 step 1 default 0 value 0 flags slider white balance automatic  bool      default 1 value 1 flags update             red balance  int       min 0 max 4095 step 1 default 0 value 128 flags inactive  slider            blue balance  int       min 0 max 4095 step 1 default 0 value 128 flags inactive  slider                exposure  int       min 0 max 65535 step 1 default 0 value 885 flags inactive  volatile          gain automatic  bool      default 1 value 1 flags update                    gain  int       min 0 max 1023 step 1 default 0 value 32 flags inactive  volatile         horizontal flip  bool      default 0 value 0           vertical flip  bool      default 0 value 0   And if you are lucky it supports horizontal flip and vertical flip   Then all you need to do is to set the horizontal flip by   v4l2-ctl --set-ctrl horizontal flip 1   or the vertical flip by   v4l2-ctl --set-ctrl vertical flip 1   and then you can call your video device to capture a new video  see example below   and the video will be rotated flipped   ffmpeg -f v4l2 -video size 640x480 -i  dev video0 -vcodec libx264 -f mpegts input mp4   Of-course that if you need to process an already existing video  than this method is not the solution you are looking for   The advantage in this approach is that we flip the image in the sensor level  so the sensor of the driver already gives us the image flipped  and that s saves the application  like FFmpeg  any further and unnecessary processing

Unfortunately  the Ubuntu version of ffmpeg does support videofilters   You need to use avidemux or some other editor to achieve the same effect   In the programmatic way  mencoder has been recommended

ffmpeg -vfilters  rotate 90  -i input mp4 output mp4    won t work  even with latest source     must change the order   ffmpeg -i input mp4 -vf vflip output mp4   works fine

Alexy s answer almost worked for me except that I was getting this error      timebase 1 90000 not supported by MPEG 4 standard  the maximum   admitted value for the timebase denominator is 65535   I just had to add a parameter  -r 65535 2733  to the command and it worked  The full command was thus   ffmpeg -i in mp4 -vf  transpose 1  -r 65535 2733 out mp4

I came across this page while searching for the same answer   It is now six months since this was originally asked and the builds have been updated many times since then   However  I wanted to add an answer for anyone else that comes across here looking for this information   I am using Debian Squeeze and FFmpeg version from those repositories   The MAN page for ffmpeg states the following use  ffmpeg -i inputfile mpg -vf  transpose 1  outputfile mpg   The key being that you are not to use a degree variable  but a predefined setting variable from the MAN page     0 90CounterCLockwise and Vertical Flip   default   1 90Clockwise  2 90CounterClockwise  3 90Clockwise and Vertical Flip

User · Answer

Rotate 90 clockwise   ffmpeg -i in mov -vf  transpose 1  out mov   For the transpose parameter you can pass   0   90CounterCLockwise and Vertical Flip  default  1   90Clockwise 2   90CounterClockwise 3   90Clockwise and Vertical Flip   Use -vf  transpose 2 transpose 2  for 180 degrees   Make sure you use a recent ffmpeg version from here  a static build will work fine    Note that this will re-encode the audio and video parts  You can usually copy the audio without touching it  by using -c a copy  To change the video quality  set the bitrate  for example with -b v 1M  or have a look at the H 264 encoding guide if you want VBR options   A solution is also to use this convenience script

Since ffmpeg transpose command is very slow  use the command below to rotate a video by 90 degrees clockwise  Fast command  Without encoding - ffmpeg -i input mp4 -c copy -metadata s v 0 rotate 270 output mp4  For full video encoding  Slow command  does encoding  ffmpeg -i inputFile -vf  quot transpose 1 quot  -c a copy outputFile

Have you tried transpose yet  Like  from the other answer    ffmpeg -i input -vf transpose 2 output   If you are using an old version  you have to update ffmpeg if you want to use the transpose feature  as it was added in October 2011   The FFmpeg download page offers static builds that you can directly execute without having to compile them

User · Answer

If you don t want to re-encode your video AND your player can handle rotation metadata you can just change the rotation in the metadata using ffmpeg  ffmpeg -i input m4v -map metadata 0 -metadata s v rotate  quot 90 quot  -codec copy output m4v

If you re getting a  Codec is experimental but experimental codecs are not enabled  error use this    ffmpeg -i inputFile -vf  transpose 1  -c a copy outputFile   Happened with me for some  mov file with aac audio

To rotate the picture clockwise you can use the rotate filter  indicating a positive angle in radians  With 90 degrees equating with PI 2  you can do it like so   ffmpeg -i in mp4 -vf  rotate PI 2  out mp4   for counter-clockwise the angle must be negative  ffmpeg -i in mp4 -vf  rotate -PI 2  out mp4   The transpose filter will work equally well for 90 degrees  but for other angles this is a faster or only choice
