Hi, I understand that gstreamer has the "videotestsrc" plugin and this can be used for getting the YUV files of different formats. and i tested this on my setup and it works properly. Now i have a different requirement, where i already have YUV file and i want to encode this YUV file into H.263 format. Is it possible to specify "videotestsrc" plugin to use my YUV file for generating the YUV test stream? Will "filesrc" plugin will be able to do this? TIA. Warm Regards, prb
