Hi,
refering to this thread, I'm currently having problems capturing HD content with my Avermedia H727 capture card.
Shortly said: the actual captured live video is only covering part of the screen (the rest is a green background).
The captured source is 1280 x 720, but the canvas appears to be 1920 x 1080, resulting in only part of the screen being filled. Can this be fixed somehow ?
Also, the CPU usage is very high when viewing live capturing through the Avermedia H727. I'm assuming this suggests software decoding is used ? Is there a way to activate hardware decoding ? Or is it an encoding issue ?
I first added FFDshow Tryout, but no codec appeared in the list of codecs. Then I installed K-lite Codec and set MPEG2 decoding to DXVA for LAV, and LAV video decoder appeared in the list. However, a warning appeared that some users might experience issues. The LAV decoder didn't result in lowering CPU usage either.
My processor is not a very powerful one (Intel Quad-Core Processor J1900), but it should have hardware acceleration for both decoding and encoding for both MPEG2 and H264.
One last question: there appears to be a lag of about 3-4 seconds between viewer-pc and NPVR-server. Is there a way to reduce this ?
Many thanks for looking into this !
