mpeg_decode_postinit() failure

2

I'm trying to take some thumbnails via ffmpeg command. My file name is "aaa.ts" and I want to take some thumbnails every second.

Frankly, it works, but I have 4 red lines in terminal. So can you tell me what kinds of problem I have and give me some solutions?

My command was:
ffmpeg -i aaa.ts -r 1 screenshot%03d.png

It makes some pngs in the directory, but the very first two or three are completely grey and the output from the command have these four errors.

  1. [mpeg2video @ 0x24bed10]mpeg_decode_postinit() failure
  2. [mpeg2video @ 0x24bed10]warning: first frame is no keyframe
  3. [mpeg2video @ 0x24bed10]ac-tex damaged at 31 60
  4. [mpeg2video @ 0x24bed10]Warning MVs not available

I have the same error message with avconv command built on Mar 16 2015 13:26:50 with gcc 4.6.3. This question is not localized at all not in geographic area nor in time, please reopen – Zac – 2016-01-18T20:45:49.610

2You are using an old FFmpeg version (version 0.6.x is from 2010), try to update to a recent version first. This probably solves your problem. – Nick van Tilborg – 2013-04-17T06:49:01.673

@NickvanTilborg I know it's idiot question, but which is the most new version of ffmpeg? and how can I update in terminal. Franky, I'm so new in linux system, I can not find where it is;; give me some hint :D – Juneyoung Oh – 2013-04-17T09:58:38.623

The best way, in my opinion, is downloading the latest sourcefiles from FFmpeg Downloads. Then run the configure and make commands to compile the program. Compiling FFmpeg can help you out. Also a simple google throws thousands of hits on installing FFmpeg on a server.

– Nick van Tilborg – 2013-04-17T10:30:29.947

If you don't want to build anything, you can also run a static build from the download page (http://ffmpeg.org/download.html) if your kernel isn't too old.
