最近開啟某個mp4影片時，會出現類似天線收訊不良的狀況。 用media player classic(6.4.9.1)播放時會變成這樣 http://img85.imageshack.us/img85/5348/dscf2642s.jpg 但是用print screen卻是一片黑 http://img822.imageshack.us/img822/1575/123gc.jpg 想說可能是轉碼器的問題， 改用萬能的kmplayer(2.9.4.1436，免安裝版)來試試， 結果就好像在沒有開燈的房間摸黑一樣： http://img20.imageshack.us/img20/5417/dscf2645z.jpg 可是用kmplayer內建的擷圖功能卻 http://img20.imageshack.us/img20/8359/r224145731.jpg 我只安裝了以前進板畫面說的那幾個基本的轉碼器和coreavc1500， 用Gspot分析 http://img810.imageshack.us/img810/836/20100706154029.jpg 先不管這兩個播放軟體擷圖的結果為何相反， 請問要怎樣才能正常看影片呢？ 附上從kmplayer抓下來的該影片相關資訊： General Complete name : D:\********\*********\************************** Format : MPEG-4 Format profile : Base Media / Version 2 Codec ID : mp42 File size : 229 MiB Duration : 23mn 31s Overall bit rate : 1 360 Kbps Encoded date : UTC 2010-06-30 13:35:35 Tagged date : UTC 2010-06-30 13:49:04 Writing application : HandBrake 0.9.4 2009112300 Video #1 ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : [email protected] Format settings, CABAC : Yes Format settings, ReFrames : 2 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 23mn 31s Bit rate mode : Variable Bit rate : 1 200 Kbps Width : 720 pixels Height : 416 pixels Display aspect ratio : 1.538 Frame rate mode : Variable Frame rate : 29.970 fps Minimum frame rate : 14.985 fps Maximum frame rate : 62.762 fps Resolution : 24 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 0.134 Stream size : 201 MiB (88%) Writing library : x264 core 79 Encoding settings : cabac=1 / ref=2 / deblock=1:0:0 / analyse=0x1:0x111 / me=hex / subme=6 / psy=1 / psy_rd=1.0:0.0 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=0 / cqm=0 / deadzone=21,11 / chroma_qp_offset=-2 / threads=6 / nr=0 / decimate=1 / mbaff=0 / constrained_intra=0 / bframes=2 / b_pyramid=0 / b_adapt=1 / b_bias=0 / direct=1 / wpredb=0 / wpredp=2 / keyint=300 / keyint_min=30 / scenecut=40 / rc_lookahead=40 / rc=abr / mbtree=1 / bitrate=1200 / ratetol=1.0 / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00 Encoded date : UTC 2010-06-30 13:35:35 Tagged date : UTC 2010-06-30 13:49:04 colour_primaries : BT.601-6 525, BT.1358 525, BT.1700 NTSC, SMPTE 170M transfer_characteristics : BT.709-5, BT.1361 matrix_coefficients : BT.601-6 525, BT.1358 525, BT.1700 NTSC, SMPTE 170M Audio #2 ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format version : Version 4 Format profile : LC Format settings, SBR : No Codec ID : 40 Duration : 23mn 31s Bit rate mode : Variable Bit rate : 160 Kbps Maximum bit rate : 208 Kbps Channel(s) : 2 channels Channel positions : L R Sampling rate : 48.0 KHz Resolution : 16 bits Stream size : 26.9 MiB (12%) Encoded date : UTC 2010-06-30 13:35:35 Tagged date : UTC 2010-06-30 13:49:04 --
