当我运行ffmpeg时,我可以看到“默认”音频和视频流:
Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 960x400 [SAR 1:1 DAR 12:5], 3859 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc
(default)
Metadata:
creation_time : 2013-05-03 22:50:47
handler_name : GPAC ISO Video Handler
Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 92 kb/s
(default)
Metadata:
creation_time : 1970-01-01 00:00:00
handler_name : SoundHandler
Stream #0:2: Video: mjpeg, yuvj420p(pc), 675x1000 [SAR 72:72 DAR 27:40], 90k tbr, 90k tbn, 90k tbc
据我所知,如果未设置地图选项,则在编码时由ffmpeg选择此流作为输入。
如何使用ffprobe获取“默认”流?
抱歉英语
