[MPlayer-users] vf.c: have to REALLOCATE buffer memory :(

[Brian Neltner]

Hello.

With recently encoded movies, I am finding that in some cases, the end resulting file both causes avidemux to segfault (? maybe ODML, so a different problem, though in the past, regenerating the frames has fixed this) on playing, and, while it plays in mplayer, applying the following postprocessing filters (from my config file)

vf=spp,noise=8ah:5ah
autoq=3

results in this message being printed on every other frame (commenting the pp filters eliminates the problem, the filters do, however, work properly on any movies I encoded in the past.).

vf.c: have to REALLOCATE buffer memory :(

At first, I thought this was a scaling issue-- scale=560:-2 resulted in this error while scale=560:288 (or whatever, multiples of 16) seemed not to.  I actually even tested this, and found that a movie I encoded with the scale=560:-2 worked cleanly with the hardcoded in scale.  However, I just encoded several more samples, and it seems that the problem lay elsewhere.

I included the output below from running mplayer with the postprocessing filters below, the movie was encoded using the command:

I encoded a movie which seemed successful using this exact same command varied by crop dimensions only, but I didn't test it individually before concatenating it to the first disk in the series; however, the concatenated version works beautifully.

Another possible alteration between the successful and unsuccessful versions is that I definately used cmp=2 in the unsuccessful version and used cmp=3 in the first of the two movies I concatenated.

The output from the unsuccessful run is below.
