Стоит Debian Jessie на VirtualBox
Почти любое видео без проблем играется таким образом:
gst-launch playbin uri=file:///mnt/videos/3.mkv
gst-launch-1.0 playbin uri=rtsp://userMY.ddns.net:554/ch0_0.h264
gst-launch-1.0 playbin uri=rtsp://admin:12345@192.168.2.239/Streaming/Channels/1?transportmode=unicast&profile=Profile_1
gst-launch-1.0 filesrc location=3.mkv ! decodebin name=dec ! queue ! autovideosink dec. ! queue ! autoaudiosink
- 1. Как узнать, какие кодеки вписывать для определенных видео в данном конвеере?
- 2. Как выводить в этом конвееере на экран без использования autovideosink, учитывая что всё это на VirtualBoxe?
- 3. Как мне сохранить запись с видео камер в любой видео формат? например, после таких строк оно ничего не записывает и ругается:
root@Jessie:/mnt/videos# gst-launch-1.0 rtspsrc location=rtsp://admin:12345@192.168.2.239/Streaming/Channels/1?transportmode=unicast&profile=Profile_1 ! rtph264depay ! mpegtsmux ! filesink location=file.mp4
