To elaborate:
avconv contains several hundred known bugs that 
are not reproducible with ffmpeg, some of them 
security relevant, please understand that we 
therefore cannot support it here.

See http://blog.pkh.me/p/13-the-ffmpeg-libav-situation.html

I know it's confusing but this is the wrong mailing list for the
software you use. You should probably subscribe to
libav-to...@libav.org. Libav is a fork of ffmpeg and not supported on
this mailing list.

HTH,

[Libav-user] High bitrate in AVCONV converted MPG file causes DVD reading problem

2013-07-30 Thread Ivaylo Spasov 
I convert AVI to MPEG with folowing command:

avconv -i file.avi -c:v mpeg2video -b:v 6000k -c:a mp2 -b:a 384k file.mpg

When the MPG file has been burned to DVD it is hard to read afterthat.
The DVD on the computer starts to make noise and to read slow the DVD.
Also it is hard to watch directly - it is like there is no buffer in
the VLC player. The Windows media player doesn't even play the MPG
file.

I checked with avprobe the MPG file and another MPG file made with
EDIUS program. Here are the resuts:

MY MPG FILE

avprobe my-file.mpg
avprobe version 0.8.6-4:0.8.6-0ubuntu0.12.04.1, Copyright (c)

EDIUS CREATED MPG FILE

avprobe edius.mpg

2007-2013 the Libav developers
  built on Apr  2 2013 17:00:59 with gcc 4.6.3
[mpeg @ 0x8449240] max_analyze_duration reached
Input #0, mpeg, from 'edius.mpg':
  Duration: 00:34:56.47, start: 0.346411, bitrate: 2290 kb/s
Stream #0.0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576
[PAR 16:15 DAR 4:3], 6000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc
Stream #0.1[0x1c0]: Audio: mp2, 48000 Hz, stereo, s16, 256 kb/s

The two files are with great quality but I am questioning myself how
to achieve two things:

What to change in my command line to reach edius bitrate on that line:

  Duration: 00:34:56.47, start: 0.346411, bitrate: 2290 kb/s

instead of:

  Duration: 00:34:56.47, start: 1.00, bitrate: 6411 kb/s

And how to reach this 6000kb in Edius STREAM line:

Stream #0.0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [PAR
16:15 DAR 4:3], 6000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc

instead of mine 104857kb :

Stream #0.0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [PAR
16:15 DAR 4:3], 104857 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc

I think that will resolve my problem with burning and reading DVDs.

ALso whe I am converting the yellow sigh appears:

[mpeg @ 0x8e75f40] VBV buffer size not set, muxing may fail

Is this a part of the problem?

Thanks in advance!
