請問dm8127是否支援3路 h264 1280x720 60fps, h264 640x480 30fps, mjpeg 5fps 壓縮?
我目前使用dm8127 rdk3.5, h264enc 版本是 ivahd.02.00.04.01. usecase是參考multich_tristream_fullfeature.c 並加上 capturedisplay.c 的 YUV_FRAMES_TO_A8 的部分流程
雖然h264 1280x720 60fps這一路視頻是60fps輸出, 但是單張單張撥放會發現偶數楨其實是重複奇數楨的內容!!但是30fps是正確的.
但是透過YUV_FRAMES_TO_A8擷取rawdata, 確定偶數張畫面是有變動的.
