Set cover image while record audio in android -


hello recording audio using mediarecorder , save in mp4 format. , upload server. record video mp4 using camera , upload server.
while receive uploaded item server uploaded url list. , playing in videoview. video , audio play good. here thing while playing video it's display video frame on video view while playing audio it's black. audio , video file extension mp4 can't make different while adding in videoview other wise i'll add imageview , display default image , hide videoview.
there way record audio cover image while playing in video view display cover image...
know using ffmpeg can got lots of error while compiling in windows pc. there way add cover image while record audio pure android api? sorry bad english.

i google can't find solution convert audio file video file using image. have go ffmpeg.

so add writingminds java ffmpeg in project using gradle dependency. convert mp4 audio cover image mp4 video.

there limitation in precompile library. not work in android 24 , commands -speed, cpu-used, -deadline important operation(but still can perform other operation). there disadvantage slow speed, , features required specific operation not include in compile library. (so gave advice compile own ffmpeg library android project in linux or mac pc(windowns have lots of issues)).

i hope who's type of scenario :)

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
