Add watermark

[Hamilton Vera]

Greetings everyone. I am writing a gstreamer based application and I
am wondering about the best approach to add a watermark during
streaming generation.

Please let me know if you have any tip.

Thanks in advance.

Try using something like pngdec to decode a still picture and
videomixer to overlay it on top of the video.

I coded this pipeline:

                               queue_audio -audio_dec - autoaudiosink
filevideo - demuxer ->
                               queue_video - video_dec - coglogoinsert - ffmpegcolorspace - autovideosink

in order to display an image onto a video.
(I set the property "location" to load the png image).
There are no error in lines regarding the pipeline, but I always return a segmentation fault.

Suggestions??

Hi,

You can also use videomixer combined with alpha attribute of the pads to insert a bigger watermarking that could affect the whole image:
http://developer.gnome.org/gst-plugins-libs/0.10/gst-plugins-good-plugins-videomixer.html

The key plugings would be:
videomixer
imagefreeze (for the watermark)
[videoscale] (optional)

Best,

Angel
