does not read mpeg transport streams since #1643467

[James Cameron]

Since the security update to 6:9.20-0ubuntu0.14.04.1 triggered today by #1643467, vlc and mplayer do not play mpeg transport streams that were previously playable. Other types of stream are unaffected.

MPlayer interrupted by signal 11 in module: decode_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
  won't help unless you provide this information when reporting a possible bug.
 [ This binary of MPlayer in Debian is currently compiled with
   '--enable-debug'; the debugging symbols are in the package
   'mplayer-dbg'.]

I'll attach a stream that causes the problem. It is from a DVB-T card, filtered by pid.

The package with regression is libavcodec54.

Previous working version before updates was https://launchpad.net/ubuntu/trusty/amd64/libavcodec54/6:9.18-0ubuntu0.14.04.1

A workaround, downgrade only this package to 6:9.18-0ubuntu0.14.04.1 does properly play streams.

I want the #1643467 Firefox fix as well, so I've made a local copy of libavcodec.so.54 for use with mplayer or vlc via LD_LIBRARY_PATH.

Status changed to 'Confirmed' because the bug affects multiple users.
