draw times text on video

[zhangjay]

Dear all

I am using imx processor's vpu API program, I want to draw the time text(for example: 2013-01-01), on the video which recorded with camera and processed by vpu.

I successed record the video by vpu API to a H264 file, but I want to add a text on the video.

I don't know how to do it.

Anyone can give me some example?

Sorry for my poor English.

Thanks anyway.

Best Regards.

if it is possible, you can convert you VPU code into a gstreamer element, then once you have it you can use it and add text on top with the textoverlay element.

Dear Leonardo,

Where to get the guide for build gstreamer on mx27 board, is there any documents?

Thanks!

There is a documentation file called 'Multimedia Linux Codecs SDK Release Notes for i.MX27 ADS', it has instructions to install GStreamer. Check the MX27 main page, the documents section.

Hi Leonardo

I downloaded the gst-fsl-plugin and added it into my ltib, when using arm926-ejs toolchain I got the error message, it seems that the *.so files in the lib don't support my cross-compile toolchain.

When I can get the source of those lib.

Here is my another question
