[Regression] MPlayer r31324 stops playing network streams after pausing a few of minutes (lavf demuxer)

[cosoleto@…]

I can reproduce this problem always following these steps:

1) mplayer ​http://address.org/file.mp4
2) PAUSE (5 minutes)
3) PLAY

and MPlayer will stop playing quickly.

This change introduced the bug:

Di not do a stream_reset on seeking backwards, the seek itself should
do whatever is best/necessary, this method will just drop cached data.

This worked before only out of pure luck (and wasted a huge amount of network bandwidth), if you had been playing e.g. a MPEG-TS file it would never have worked.
Anyway this should be implemented (closer to) properly in SVN r32954.

Thanks for taking care of this bug. Unfortunately it doesn't look fixed yet (r32954).

Please try again with 32977, the previous approach wasn't really reliable (basically it mostly only worked with -nocache).

It works now. There is only a little side effect in the initial phase: mplayer prints a dozen of "nop_streaming_read error : Bad file descriptor" warning after an unnecessary HTTP GET request to the server that returns with a "Request Range Not Satisfiable" error. Log attached.
