bmdcatrure采集模式

帖子 jvip_chen » 2019年 1月 6日 09:51 星期天

我成功地应用你的补丁,但是我不能拍摄1080 p视频信号通过SDI输入。

这是我的设置(Video Source)——sdi - - - - - >[Decklink mini recorder]- - - - - - >[BMDCapture]- - - - - - >[AVCONV]。

bmdcapture - h

用法:bmdcapture - m[OPTIONS]

- m <mode id >:

- > DeckLink Mini Recorder(- c 0)

支持视频输出显示模式和像素格式:

0: NTSC 720 x 486 29.97 FPS
1: NTSC 23.98 720 x 486 23.976 FPS
2: PAL 720 x 576 25 FPS
3: NTSC Progressive 720 x 486 59.9401 FPS

bmdcapture -m 2 -A 1 -V 1 -F nut -f pipe:1
bmdcapture -C 0 -m 5 -A 2 -c 2 -V 4 -F nut -f pipe:1 | /usr/local/bin/avconv -re -i -
