H.264 Cpu Usage


Let's be honest here: x264 is an incredibly well-optimized encoder, and many people still use it.

Next, ffvp9 versus ffhevc/openhevc: they both scale about the same. this content

Initially simple_player starts 1:1 size. Nonetheless, I can understand Google's contribution to libvpx does not focus on that since it is not an essential requirement for them. This entry was posted in General. Next, let's compare ffvp9 with libvpx-vp9.

mhh, atm I let the encoding run during doing something other, because the pc isnīt slowed down for office use. So here, I will compare encoding (quality+speed) and decoding (speed) performance of VP9 vs. Last edited by _Al_; 26th Nov 2013 at 19:46. I know that there has been some conflation same places in the literature between the two concepts of a video format specification and the actual software/hardware to translate to/from that format.

I've often wondered if averaging of all video frames for SSIM is correct; it seems like a side-by-side box plot might be revealing, particularly with regard to outliers? In reality with most general multi-threaded apps, 1 hyperthreaded core = 1.5x the throughput (but windows expects it to be 2x) ...

[I previously presented this at the Webm Summit and VDD15, and a Youtube version of that talk is available also.] Encoding quality The most important question for video codecs is quality.

I couldn't address this question back then, because the blog post was primarily about decoders, and FFmpeg's decoder for HEVC was immature (from a performance perspective). High Encoding Cpu Usage Obs Here is an example: cls @echo off echo. I believe -tune fastdecode is what you are looking for. Could you help me to resolve this?

The Real Problem: Hardware Acceleration There's one simple, core problem here. R1ch's Log Analyzer Google solved this problem by adding VP8 and VP9 to Chrome and telling YouTube to serve VP9 and VP8 videos to Chrome. I'd use x264, and do it just like this: x264.exe foo.avs --qp 0 --preset faster --tune fastdecode --keyint 24 --output foo_lossless.mp4 Then take the resulting MP4 file and transcode with x264.

But you will get maximum quality footage stored into the archive at the same time: If you don't know the URL for a stream of lower quality, or simply don't want and point in the right direction on getting a multithreaded AVISynth.

I suggest you post in the MEGUI forum. news Cman212nd January 2011, 18:45yes i never heard about using x264 before other than through a gui and when i looked into my x264.exe folder i saw that there was also a Source: M2TS - 1080p - AVC Commandline: --profile high --level 4.1 --preset fast --pass 2 --aud --bitrate 12920 --threads auto --thread-input --b-pyramid 2 --keyint 24 --min-keyint 1 --b-adapt 1 --me umh Enter Your Email Here to Get Access for Free:

For VP8 and VP9 videos, you'll see "video/webm" and either "vp9" or "vp8". This is a de facto industry-wide standard beyond just web browsers. I'm sure an x264 dev would be better qualified to say for sure though. http://computerhelpdev.com/cpu-usage/awk-cpu-usage.php The OBS default is veryfast, which for the majority of cases is the best balance between CPU usage and video quality.

If I show high-end results, the difference is indeed harder to see, and it takes considerable time to explain the differences, which (as you mentioned) makes it all sound much less Obs Encoding Settings For Recording You can keep your Base resolution the same, so that your layout doesn't change, and then downscale the resolution to whatever gives you good performance. The underlying technologies are covered by a wide variety of patents.

Why Did Google Create VP8 and VP9?

Sun, 12/15/2013 - 17:16 Hi Roman, Thank you for your reply I try to set ippSetNumThreads(1) and the CPU usage is still about 60~70% Hi Igor, Thank you for your reply My Derek Cman2113th December 2010, 07:02yes, thank you! This means playback takes less CPU time, which means less battery power is wasted and less heat is generated. Obs Encoder Download The different downscale filters (bilinear, bicubic, and Lanczos) simply change the algorithm used to shrink the picture: bilinear is fastest and takes the fewest resources, but doesn't look as good, while

I encode with the Adobe Media Encoder. This is expected, the backwards adaptivity feature in VP9 affects multithreaded scaling somewhat, and ffh264 doesn't have such a feature. You should be seeing >90% avg. check my blog Have to poke around some more; suspect something else is getting in the way.
