[MEncoder-users] demuxing question

[Rick C.]

Hello,

I've encountered a problem and I hope someone can help me find out what's wrong.  Here's my command:

test.flv -ovc lavc -lavcopts vcodec=mpeg4 -ffourcc XVID -oac faac -o test.avi

The video I'm converting is 10 minutes and with a recent MEncoder build I only get about 4 minutes output.  But with a MEncoder build I have from last year I get the full 10 minutes.  Here is some output that might show the problem:

libavformat file format detected.
[lavf] Video stream found, -vid 0
[lavf] Audio stream found, -aid 1
VIDEO:  [H264]  480x360  0bpp  29.917 fps    0.0 kbps ( 0.0 kbyte/s)
[V] filefmt:44  fourcc:0x34363248  size:480x360  fps:29.917  ftime:=0.0334

That is from the good one and this the bad:

libavformat file format detected.
[flv @ 0x101857400]Estimating duration from bitrate, this may be inaccurate
[lavf] stream 0: video (h264), -vid 0
[lavf] stream 1: audio (aac), -aid 0
VIDEO:  [H264]  480x360  0bpp  59.750 fps  573.7 kbps (70.0 kbyte/s)
[V] filefmt:44  fourcc:0x34363248  size:480x360  fps:59.750  ftime:=0.0167

And the end:

Pos: 233.9s  12706f (66%) 218.85fps Trem:   0min  36mb  A-V:-0.030 [736:128]
Too many audio packets in the buffer: (4096 in 1584970 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

I only posted a small portion because I noticed in the good one it accurately reads 29.917fps but the bad a very different number.  The rest of the output was about the same but I can post more if needed.  Any idea why this might be happening or an idea of what else I can check?  I honestly can't remember if I did something different compiling the MEncoder from last year.  Thanks for your help!
