使用RV1126进行画中画操作时搜索mix关键字如下:
firefly@firefly:~$ gst-inspect-1.0 | grep mix
audiomixer: audiointerleave: AudioInterleave
audiomixer: liveadder: AudioMixer
audiomixer: audiomixer: AudioMixer
typefindfunctions: multipart/x-mixed-replace: no extensions
audiofxbad: audiochannelmix: Simple stereo audio mixer
openglmixers: glmosaic: OpenGL mosaic
openglmixers: glstereomix: OpenGL stereo video combiner
openglmixers: glvideomixerelement: OpenGL video_mixer
openglmixers: glvideomixer: OpenGL video_mixer bin
openglmixers: glmixerbin: OpenGL video_mixer empty bin
videomixer: videomixer: Video mixer 2
audiomixmatrix: audiomixmatrix: Matrix audio mix
未发现有rockchip 相关使用硬件的插件,在使用videomixer进行画中画混合时视频延时变的非常大,怀疑时CPU混合造成延时大,请问是否有硬件videomixer插件?
debain系统中搜索rockchip相关插件如下:
firefly@firefly:~$ gst-inspect-1.0 | grep rockchip
rockchipmpp: mppjpegdec: Rockchip's MPP JPEG image decoder
rockchipmpp: mppjpegenc: Rockchip Mpp JPEG Encoder
rockchipmpp: mppvp8enc: Rockchip Mpp VP8 Encoder
rockchipmpp: mpph264enc: Rockchip Mpp H264 Encoder
rockchipmpp: mppvideodec: Rockchip's MPP video decoder
