Implemented Interfaces

GstMultiFileSrc implements GstURIHandler.

Description

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

1
2
3
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.
