Capturejayhx Release Notes
CapturejayHX release notes - Version 2.3.7 - 1.7.17.10600 – 09/01/2019 - capturejayHX adds support for streaming and network playback of Secure Reliable Transport (SRT) feeds. SRT is a protocol designed for live video streaming over the public internet and provides reliable transmission similar to TCP, however, it does so at the application layer, using UDP protocol as an underlying transport layer. It supports packet recovery while maintaining low latency (default: 120 ms). SRT also supports encryption using AES. - Added RTP streaming support - Added RTP Pro-MPEG streaming support - Added MJPEG encoder for UDP streaming - Updated FFmpeg to version 4.0.2 - Added QuickSync H.264 video encoding and multichannel audio support (up to 16 channels) for WebRTC - Improved playback of RTSP streams. - Updated NDI to 3.5 version. - Updated NVIDIA components to Video_Codec_SDK_8.1.24 - Lots of other improvements and fixes in the capture/playback engine.

Download Media Player Codec Pack Version 4.1 Media Player Codec Pack
download media player codec pack version 4.1 Media Player Codec Pack. Description: In Microsoft Windows 10 it is not possible to set all file associations using an installer. Microsoft chose to block changes of file associations with the introduction of their Zune players. Third party codecs are also blocked in some instances, preventing some files from playing in the Zune players. A simple workaround for this problem is to switch playback of video and music files to Windows Media Player manually. In start menu click on the "Settings". In the "Windows Settings" window click on "System". On the "System" pane click on "Default apps". On the "Choose default applications" pane click on "Films & TV" under "Video Player". On the "Choose an application" pop up menu click on "Windows Media Player" to set Windows Media Player as the default player for video files. Footnote: The same method can be used to apply file associations for music, by simply clicking on "Groove Music" under "Media Player" instead of changing Video Player in step 4. Media Player Codec Pack Plus. Codec's Explained: A codec is a piece of software on either a device or computer capable of encoding and/or decoding video and/or audio data from files, streams and broadcasts. The word Codec is a portmanteau of ' co mpressor- dec ompressor' Compression types that you will be able to play include: x264 | x265 | h.265 | HEVC | 10bit x265 | 10bit x264 | AVCHD | AVC DivX | XviD | MP4 | MPEG4 | MPEG2 and many more. File types you will be able to play include: .bdmv | .evo | .hevc | .mkv | .avi | .flv | .webm | .mp4 | .m4v | .m4a | .ts | .ogm .ac3 | .dts | .alac | .flac | .ape | .aac | .ogg | .ofr | .mpc | .3gp and many more. -
Encoding H.264 Video for Streaming and Progressive Download
What is Tuning? • Disable features that: • Improve subjective video quality but • Degrade objective scores • Example: adaptive quantization – changes bit allocation over frame depending upon complexity • Improves visual quality • Looks like “error” to metrics like PSNR/VMAF What is Tuning? • Switches in encoding string that enables tuning (and disables these features) ffmpeg –input.mp4 –c:v libx264 –tune psnr output.mp4 • With x264, this disables adaptive quantization and psychovisual optimizations Why So Important • Major point of contention: • “If you’re running a test with x264 or x265, and you wish to publish PSNR or SSIM scores, you MUST use –tune PSNR or –tune SSIM, or your results will be completely invalid.” • http://x265.org/compare-video-encoders/ • Absolutely critical when comparing codecs because some may or may not enable these adjustments • You don’t have to tune in your tests; but you should address the issue and explain why you either did or didn’t Does Impact Scores • 3 mbps football (high motion, lots of detail) • PSNR • No tuning – 32.00 dB • Tuning – 32.58 dB • .58 dB • VMAF • No tuning – 71.79 • Tuning – 75.01 • Difference – over 3 VMAF points • 6 is JND, so not a huge deal • But if inconsistent between test parameters, could incorrectly show one codec (or encoding configuration) as better than the other VQMT VMAF Graph Red – tuned Green – not tuned Multiple frames with 3-4-point differentials Downward spikes represent untuned frames that metric perceives as having lower quality Tuned Not tuned Observations • Tuning -

EMA Mezzanine File Creation Specification and Best Practices Version 1.0.1 For
16530 Ventura Blvd., Suite 400 Encino, CA 91436 818.385.1500 www.entmerch.org EMA Mezzanine File Creation Specification and Best Practices Version 1.0.1 for Digital Audio‐Visual Distribution January 7, 2014 EMA MEZZANINE FILE CREATION SPECIFICATION AND BEST PRACTICES The Mezzanine File Working Group of EMA’s Digital Supply Chain Committee developed the attached recommended Mezzanine File Specification and Best Practices. Why is the Specification and Best Practices document needed? At the request of their customers, content providers and post‐house have been creating mezzanine files unique to each of their retail partners. This causes unnecessary costs in the supply chain and constrains the flow of new content. There is a demand to make more content available for digital distribution more quickly. Sales are lost if content isn’t available to be merchandised. Today’s ecosystem is too manual. Standardization will facilitate automation, reducing costs and increasing speed. Quality control issues slow down today’s processes. Creating one standard mezzanine file instead of many files for the same content should reduce the quantity of errors. And, when an error does occur and is caught by a single customer, it can be corrected for all retailers/distributors. Mezzanine File Working Group Participants in the Mezzanine File Working Group were: Amazon – Ben Waggoner, Ryan Wernet Dish – Timothy Loveridge Google – Bill Kotzman, Doug Stallard Microsoft – Andy Rosen Netflix – Steven Kang , Nick Levin, Chris Fetner Redbox Instant – Joe Ambeault Rovi -

AVC, HEVC, VP9, AVS2 Or AV1? — a Comparative Study of State-Of-The-Art Video Encoders on 4K Videos
AVC, HEVC, VP9, AVS2 or AV1? | A Comparative Study of State-of-the-art Video Encoders on 4K Videos Zhuoran Li, Zhengfang Duanmu, Wentao Liu, and Zhou Wang University of Waterloo, Waterloo, ON N2L 3G1, Canada fz777li,zduanmu,w238liu,[email protected] Abstract. 4K, ultra high-definition (UHD), and higher resolution video contents have become increasingly popular recently. The largely increased data rate casts great challenges to video compression and communication technologies. Emerging video coding methods are claimed to achieve su- perior performance for high-resolution video content, but thorough and independent validations are lacking. In this study, we carry out an in- dependent and so far the most comprehensive subjective testing and performance evaluation on videos of diverse resolutions, bit rates and content variations, and compressed by popular and emerging video cod- ing methods including H.264/AVC, H.265/HEVC, VP9, AVS2 and AV1. Our statistical analysis derived from a total of more than 36,000 raw sub- jective ratings on 1,200 test videos suggests that significant improvement in terms of rate-quality performance against the AVC encoder has been achieved by state-of-the-art encoders, and such improvement is increas- ingly manifest with the increase of resolution. Furthermore, we evaluate state-of-the-art objective video quality assessment models, and our re- sults show that the SSIMplus measure performs the best in predicting 4K subjective video quality. The database will be made available online to the public to facilitate future video encoding and video quality research. Keywords: Video compression, quality-of-experience, subjective qual- ity assessment, objective quality assessment, 4K video, ultra-high-definition (UHD), video coding standard 1 Introduction 4K, ultra high-definition (UHD), and higher resolution video contents have en- joyed a remarkable growth in recent years. -
