crash playing H.264 after Unknown NAL code: 12

[mplayer-bugs@…]

mplayer crashes when I ask it to play a raw H.264 transport stream from my
Tandberg 5930 hardware encoder.

VDec: vo config request - 544 x 480 (preferred csp: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.37:1 - prescaling to correct movie aspect.
VO: [xv] 544x480 => 660x480 Planar YV12
[h264 @ 0x85fb420]Unknown NAL code: 12
mplayer: h264.c:3164: fill_default_ref_list: Assertion `best_i != -1' failed.

MPlayer interrupted by signal 6 in module: decode_video

• MPlayer crashed. This shouldn't happen.

If it turns out that the NAL code 12 is the problem then I offer this explanation:

When you encounter filler data you can expect the following:

00 00 01 0c (ff)* 80

Basically, a metric buttload of ff bytes followed by an 80. Of course, you

can save yourself some stress and just search for the next 00 00 01 NAL unit
start code.

I'm not surprised you don't handle filler. It only appears in

constant-bit-rate video which is foolish for computer movie files.
Unfortunately, this type of video is ubiquitous in the television broadcast
industry (cable, satellite).

Please provide a sample file otherwise we can't fix it. Also please try CVS,
pre7 is very old.

This is the first 900k of a 26M transport stream. You should find 34
renderable frames. The stream is "raw" (it does not begin or end cleanly). It
triggers the crash the same as the full 26M file.

Plays fine for me using latest CVS, though I get only 27 frames.
