multifilesrc

Reads buffers from sequentially named files. If used together with an image decoder, one needs to use the caps property or a capsfilter to force to caps containing a framerate. Otherwise image decoders send EOS after the first picture. We also need a videorate element to set timestamps on all buffers after the first one in accordance with the framerate.

File names are created by replacing "%d" with the index using printf().

Example launch line

 gst-launch-1.0 multifilesrc location="img.%04d.png" index=0 caps="image/png,framerate=\(fraction\)12/1" ! \
     pngdec ! videoconvert ! videorate ! theoraenc ! oggmux ! \
     filesink location="images.ogg"

This pipeline creates a video file "images.ogg" by joining multiple PNG files named img.0000.png, img.0001.png, etc.

Properties

caps 

“caps” GstCaps *

Caps describing the format of the data.

Flags : Read / Write

index 

“index” gint

Index to use with location property to create file names. The index is incremented by one for each buffer read.

Flags : Read / Write

Default value : 0

location 

“location” gchararray

Pattern to create file names of input files. File names are created by calling sprintf with the pattern and the current index.

Flags : Read / Write

Default value : %%05d

loop 

“loop” gboolean

Whether to repeat from the beginning when all files have been read.

Flags : Read / Write

Default value : false

start-index 

“start-index” gint

Start value of index. The initial value of index can be set either by setting index or start-index. When the end of the loop is reached, the index will be set to the value start-index.

Flags : Read / Write

Default value : 0

stop-index 

“stop-index” gint

Stop value of index. The special value -1 means no stop.

Flags : Read / Write

Default value : -1
