Extract frames from HTTP streamed video without downloading entire file.

[monxarat]

Hi, everyone. I want to extract frames from a streaming video (such as from youtube link). When I ran the below error has occurred. How to fix these bugs?

I ran it on Android.

String[] cmd = { "-i","https://r2---sn-ouu2j-ioqz.googlevideo.com/videoplayback?id=efc44c0db851e384&itag=22&source=youtube&requiressl=yes&mm=31,29&mn=sn-ouu2j-ioqz,sn-oguesnzl&ms=au,rdu&mv=m&pl=19&ei=qLFrXI7PEpno4gLd5IIQ&susc=yt&initcwndbps=713750&mime=video/mp4&ratebypass=yes&dur=532.433&lmt=1537615999778923&mt=1550561540&fvip=2&c=MWEB&ip=202.171.132.229&ipbits=0&expire=1550583304&sparams=ip,ipbits,expire,id,itag,source,requiressl,mm,mn,ms,mv,pl,ei,susc,initcwndbps,mime,ratebypass,dur,lmt&signature=297CF9E2B2C8140767430681FD101783C26E2F99.D3E5D049F02994C848E0A143F0A232F2E66239C7&key=yt8", "-ss", "5",  "-frames:v", "1", Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM).getAbsolutePath() + "/frame_youtube.jpg"};
