VLC دفق سطح المكتب

Question

تعديل
توقفت عن استخدام VLC والتبديل إلى GMAX FLV تشفير. يقوم بعمل أفضل بكثير.

المنشور الأصلي
أقوم بإرسال سطح المكتب الخاص بي (شاشة) كدفق فيديو H264 إلى جهاز آخر يحفظه إلى ملف باستخدام أسطر الأوامر follwoing:

مرسل الدفق:

vlc -I dummy
    --sout='#transcode{vcodec=h264,vb=512,scale=0.5}
            :rtp{mux=ts,dst=192.168.0.1,port=4444}'

مستقبل الدفق:

vlc -I rc
    rtp://@:4444
    --sout='#std{access=file,mux=ps,dst=/home/user/output.mp4}'
    --ipv4

هذا يعمل ، ولكن هناك بعض القضايا:

• الملف غير قابل للعب مع معظم اللاعبين.
• VLC قادر على تشغيل الملف ولكن مع بعض الغرابة:
• => يستغرق الأمر حوالي 10 ثوانٍ قبل بدء التشغيل بالفعل.
• => السعي لا يعمل.

هل يمكن لأي شخص أن يوجهني في الاتجاه الصحيح حول كيفية إصلاح هذه المشكلات؟

تعديل: لقد أحرزت القليل من التقدم.

:screen-fps=10
--sout='#transcode{vcodec=h264,venc=x264{keyint=40},vb=512,scale=0.5}
       :rtp{mux=ts,dst=192.168.0.1,port=4444}'

كل المساعدة موضع ترحيب!

Answer 1

تحديث سطر أوامر المرسل الخاص بك مع:

venc=x264{scenecut=20,bframes=0}

وسطر أوامر العميل الخاص بك على النحو التالي:

vlc -I rc rtp://@:4444 --sout='#std{access=file,mux=mp4,dst=/tmp/output.mp4}' --ipv4

يجب إصلاح مشاكلك. أي اللاعبين اختبرت؟

Answer 2

مرسل:

$ vlc screen:// :screen-fps=5 :screen-caching=100 --sout='#transcode{vcodec=h264,venc=x264{scenecut=20,bframes=0},vb=512,scale=0.5}:rtp{mux=ts,dst=127.0.0.1,port=1234}'
