Dear all, It might be that my question is a bit out of topic but I think you guys might be able to help.
You maybe know that a couple of modern webcams output some kind of motion JPG image. The Logitech C905 webcam does so. The data is a jpg-image without DHT segment. With the help of google I managed to patch libjpeg to be able to decode these crippled jpg-images. The code can be found here http://svn.openrobotino.org/common/trunk/lib/rec/cv_lt/jpeg_dec.cpp Still it would be nice to take the webcam's output and stream it directly to a web browser. But because of the missing DHT segment browsers are not able to decode the data. My work around right now is to decode the data with my patched libjpeg and encode again as real jpg. This works but puts my embedded platform to almost 100% cpu load. The question is if there is a way to insert the missing DHT segment to the mjpg data without the need of decoding/encoding the image. Or is there a simple way to make a mpg1 stream from these mjpg single images coming from the webcam? Any help is highly appreciated Regards Christian -- ___________________________________________ REC GmbH Dr. Christian Verbeek Robert-Koch-Str. 2, 82152 Planegg Tel: +49 89 85689672 Fax: +49 89 85902327 Mobile: +49 160 7056589 e-mail: verb...@servicerobotics.eu Geschäftsführer: Dr. Christian Verbeek Registergericht: AG München (HRB 154463) ____________________________________________ ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
