[MPlayer-users] Don't quit at EOF patch

[Michael Heydon]

In the course of playing around with time shifting I have been looking for a program that will happily seek past the end of a file and keep going, I know that description doesn't appear to make much sense but if you don't know what I'm talking about you probably don't need it. :)

This patch is a quick hack that will cause mplayer when started with the option -k, (just a random letter that wasn't in use (edit cfg-mplayer.h to change it)) to sit there when it reaches the end of a file and play the same frame over and over again (if new data is appended to the file the eof is cleared and playing resumes).

I'm not quite sure why the patch works, mplayer is a bit too complex for me to understand as well as I probably should before I start making changes to it. ATM I'm just happy that it does work.

It produces lots off errors at run time if you seek past the end of the file (seems to be related to the mp3 audio stream, I looked at fixing this but I only succeeded in muting everything, the errors don't really bother me so I probably won't continue trying) 

It's unlikely that this patch will do what you want it to but I'm posting it here as a starting point after seeing several requests for something like this (and several replies that afai can tell try to solve the wrong problem).

If you make any cool modifications to this patch that you think I might be interested in pls mail them to me (I will likely unsubscribe from the list) heydonms[at]tpg[dot]com[dot]au

Coolest line in MPlayer code: "if( 1 ) { // Let the compiler optimize this out"
