seek

I am using VideoView to play video files. I am using seekTo function in order to play the video from where it has been left off. However, I wanted to do some operations when the seek operation is finished. For that I need to use onSeekCompleteListener; however, onSeekCompleteListener is not supported with VideoView; it can be used with MediaPlayer. My Question is that "is there any way by which I can use onSeekCompleteListener" with VideoView? Thanks alot public class ObservableVideoView extends VideoView { private IVideoViewActionListener mVideoViewListener; private boolean mIsOnPauseMode =

How do I seek to a particular position on a remote (HTTP) file so I can download only that part? Lets say the bytes on a remote file were: 1234567890 I wanna seek to 4 and download 3 bytes from there so I would have: 456 and also, how do I check if a remote file exists? I tried, os.path.isfile() but it returns False when I'm passing a remote file url. jbochi If you are downloading the remote file through HTTP, you need to set the Range header. Check in this example how it can be done. Looks like this: myUrlclass.addheader("Range","bytes=%s-" % (existSize)) EDIT : I just found a better

I'm building a system where multiple slave processes are communicating via unix domain sockets, and they are writing to the same file at the same time. I have never studied filesystems or this specific filesystem (ext4), but it feels like there might be some danger here. Each process writes to a disjoint subset of the output file (ie, there is no overlap in the blocks being written). For example, P1 writes to only the first 50% of the file and P2 writes only to the second 50%. Or perhaps P1 writes only the odd-numbered blocks while P2 writes the even-numbered blocks. Is it safe to have P1 and

I have huge text file and first five lines of it reads as below : This is fist line This is second line This is third line This is fourth line This is fifth line Now, I want to write something at a random position of the third line of that file which will replace the characters in that line by the new string I am writing. I am able to achieve that with the below code : use strict; use warnings; my @pos = (0); open my $fh, "+<", "text.txt"; while(<$fh) { push @pos, tell($fh); } seek $fh , $pos[2]+1, 0; print $fh "HELLO"; close($fh); However, I am not able to figure out with the same kind of
