Hi! I've got avframes from two udp multicast video streams. I would like to scale every avframe into half (only x coordinate, e.g., 640x480->320x480) and stitch the two scaled avframes into one avframe with original size (e.g., 640x480). After that, I'll encode the generated avframes into one output video stream. My input video streams have the same encoding context. The frame rate is 30 fps. So I have about 33ms to finish the scaling and stitching. The performance is critical. I plan to use sws_scale to scale the avframe but don't know how to stitch two scaled avframes together. I prefer not to use a third party image lib.
Can anyone help me to figure that out? Thanks in advance. _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
