video - Media trans-coding using directshow -


i've used directshow sample grabber grabbing video frame , playing. time trans-code 1 video format other. i'm again planning use directshow this. filter graph this.

source filter ---> sample grabber --> file writer. know above graph ok, or need add else.

also while going through msdn, found windows media foundation going replace directshow. if switching media foundation idea or not.

thanks pradeep

sample grabber let's copy , inplace modify data coming through. typically insufficient transcoding because cannot inject new data pipeline. if source file playable, time might fine readily available filter without need write own: build pipeline , started graph transcoding.

windows media foundation going replace directshow. if switching media foundation idea or not.

mf supersede dshow years ago: migrating directshow media foundation -- july 2006. 7 years passed, , mf still not on par directshow on desktop...

these 2 apis coming side side: use whatever appropriate. take consideration media apis use, target platforms, availability of third party components extensibility might need.

fyi, windows sdk offers transcode sample:

\samples\multimedia\mediafoundation\transcode

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
