# FFmpeg image video sequencer

Create videos from image and append images to existing videos using ffmpeg

Project is available in Linux Bash script and in Python script

ffmpeg 2.1+ is required

Bash


create video from image or append image to video : 

`./ffmpeg-image-sequencer.sh -i file1:file2:file3 -f `

Video must be encoded in mjpeg or mpeg4

path_to_video_output may already exists if that is the case the image are appended to it (if the video format is correct)

Exemple
  


``./ffmpeg-image-sequencer.sh -i ./image/picture1.jpg``

This will create a MPEG4 video showing picutre1.jpg during 1 second

``./ffmpeg-image-sequencer.sh -i ./image/picture2.jpg -f video2.mpeg``

This will append picture2.jpg to video2.mpeg

Testing script
  


`./ffmpeg-appender_test.sh`

Python


Testing script : `python ffmpeg-encoder_test.py`

Testing script : what does it do ?


* download images from WEB

* create a video from image if no video existing

* create a video from image and append to existing video

The output is a video created in output directory which contains all 4 images getting from websites and with 1 second of frame rate.

How does it work ?


You can use ffmpeg create your video and append JPG image to it. 

To create the video from an existing image :

```

ffmpeg -f image2 -pattern_type sequence -start_number 0 -r 1 -i $TEMPORARY_FILE_NAME.jpg -s 1920x1080 $TEMPORARY_FILE_NAME.avi

```

* `-f image2` is Image file demuxer format

* `pattern_type sequence` is for sequential pattern

* `start_number` is the index of the sequence

* `-r 1` is the frame rate, I put it to 1 frame/s to have time to see each picture

* `-s 1920x1080` set the frame size

To append an image to an existing a video, you will have to convert this image to a temporary video first, and then concat your former video to this newly created video. To concat videos :

```

ffmpeg -i "concat:$OUTPUT_FILE_NAME.avi|$TEMPORARY_FILE_NAME.avi" -c copy $TEMPORARY_FILE_NAME_VIDEO.avi

```

* `-i "concat:$OUTPUT_FILE_NAME.avi|$TEMPORARY_FILE_NAME.avi"` take videos to concat, you can add more if you like between |

* `-c copy` will copy all video streams without reencoding
