1. Elecard StreamEye系列 可以分析H264/MPEG4/MPEG2的码流暂时不支持其它标准。
2. H264VISA 比较好的H264码流分析工具
3. Vegas vegas是interra system (www.interrasystems.com)的商业工具主要是做码流分析支持的标准比较全。也支持了最新的HEVC。这是目前看起来比较专业的工具。 HEVC 码流分析http://www.chinavideo.org/forum.php?modviewthreadtid15875
1Codecvisahttp://codecian.com/ 国产软件从最早的H264visa发展至今感觉从刚开始的玩票发展到今天专业级别的商业软件值得支持。 软件试用版30天试用20帧限制。 优点QT开发跨平台 缺点性能功能风格专业程度和真正大牛级别的商业软件相比还是有距离。 2Elecard HEVC Analyzerhttp://www.elecard.com/en/produc ... /hevc-analyzer.html 不多介绍做过264的都知道略感失望与EC传统风格“迥异” 3Zond 265http://www.solveigmm.com/en/products/zond/ 需要安装chroma界面简洁内容丰富性能稳定性待测 补充 Parabola Explorerhttp://www.parabolaresearch.com/explorer-hevc-analyzer.html 目前可以有online版本http://demo.parabolaresearch.com ... 3-4-5-1-2-2-1-2-3-2 外观漂亮 codecvisa也有类似的online版本在线版本普遍功能有限 YUV Viewer
有很多YUV viewer 可以支持YUV420 Planar/semi/packed format 还可以支持更高的bitdepth(8/10/12/14)和YUV422/444等。
下面是这些工具
1. YUVPlayer
http://www.yuvplayer.com/ Main features:
playback of raw YUV video files in different resolutions, pixel formats and frameratespossibility to view separate (Y, U or V) components of video framespossibility to create header (.hdr) file for any raw YUV file describing its propertiespossibility to save individual frames in 24-bit .bmp formatpossibility to copy individual frames to the clipboarduser friendly interface
目前只是支持yuv400/yuv420, 8bit. 支持很多不同的分辨率可以用户自定义分辨率。并且支持多个YUV 文件的比较这是比较有用的功能。 2. YUVTools
http://www.sunrayimage.com/
这个工具的功能比较强大支持很多的YUV格式和分辨率根据特别的是支持YUV编辑可以用来生成encoder需要的输入YUV。但是这个工具不是免费的网上有一些破解教程可以参考。
It accepts (plays, converts, edits and analyzes) the combination of following formats: YUV in 4:4:4, 4:2:2 or 4:2:0 sample format,RGB in 4:4:4 sampling format;in different component order, like YUV, YVU, UYV, RGB, BGR, etc.in progressive (one single frame) or interlaced (two fields) format;in planar (YYY...UUU...VVV...) or packed (YUV, YUV....) pixel format;in predefined or arbitrary resolutions;Support FOURCC ( refer to: http://www.fourcc.org/). An image preview function to help guess the video format interactively.YUV Player can open multiple player dialogs and play different files in each dialog separately, or play multiple video files in one player dialog one by one sequentially. The detailed format of any opened or generated files will be logged, and the user can directly select any file to play back from the history list.YUV Converter can convert any combination of the format to another format, or convert to (or from) a sequence of BMP files. Other conversion functions include: scaling, join, crop, flip, padding, merge and separation of color components.YUV Analyzer can be used to calculate PSNR between two YUV files, or compare pixel by pixel to check the difference between the corresponding frames of two files, or overlay block type or motion vectors on top of each frame. Another useful feature is to help check the motion between two adjacent frames.YUV Editor can be used to edit the images pixel by pixel, or overlay one YUV image on top of another YUV image file.Convert YUV file to AVI format or vice versa;Setting options include grid display, different YUV to RGB conversion formula, etc.Many of above functions can also be performed in command line mode, which are useful for batch process or scripting. 3. Elecard YUVViewer
Elecard是非常好的码流分析工具它同时还提供了一个YUVviewer。
http://www.elecard.com/en/products/professional/analysis/yuv-viewer.html
Displays YUV sequences;Compares files for binary image matching;Displays the comparison results;Calculates quality metrics(PSNR, APSNR, MSE, MSAD, Delta, SSIM and VQM).
IYUV (I420);IYUV 10bit;RGB24;RGB32;UYVY (Y422, UYNV, HDYC);Y400;Y422 10bit;YUY2 (YUNV, V422, YUYV);YV12;YV16;YVYU.
下载 http://www.onlinedown.net/soft/98570.htm Elecard YUV Viewer设计用来查看YUV视频文件的YUV数据序列文件互相比较以找出二进制图像是否匹配并查看比较的结果。该应用程序还允许用户计算如信噪比NQI那斯达克指数和VQM质量度量。
可惜不是免费的。 4. PYUV 佩鲁贾大学开发free工具
PYUV: raw video sequence player
支持很多种的color space支持各种的YUV400/420/422/444等。支持更高的bitdepth包括10bit、12、14、16等可以用户输入支持用户自定义的分辨率。唯一不好的就是没有提供YUV比较的功能。5. vooya工具 freeVooya: raw YUV/RGB Video Player Detects format and color space by file name (currently YUV, XYZ, YIQ and RGB are supported), 4:0:0, 4:2:0, 4:2:2, 4:4:4, planar, interleaved and arbitrary bit depths up to 16bit fixed point, and also exotic or special formats like v210, NV12 etc.Remembers file formatsGuesses format from file nameDrop / copy single frames (png, bmp, jpg)Drawing annotationsMagnifier, pixel-exact viewAdvanced DeinterlacingSingle color channel viewDifference mode, PSNR and MSE measurementsDisplays HEVC Coding Unit indices and partition indexGrid overlay for identifying H.264 MacroblocksControl brightness, contrast and gammaTwo players can be synchronizedCan read Kakadu .vix filesCan read YUVPlayer Deluxe header filesTools to reverse yuv files, extract single frames or sub-sequencesMac OSX, Linux and WindowsFree for the time being 支持各种YUV格式包括400/420/422/444支持多种bitdepth可以支持yuv比较是free的工具。
