    Re: ffmpeg Script for batch convert video files into mp4 for iDevice really fast!

    Tried the script for newer ffmpeg and this works now, but still get a bad a/v sync, sound way ahead of video, when converting mp4 to mkv

    (Elephants Dream (1080p) from Blender project)
    Code:
    Duration: 00:10:53.79, start: 0.000000, bitrate: 3519 kb/s
        Stream #0:0(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, s16, 125 kb/s
        Stream #0:1(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 3391 kb/s, 24 fps, 24 tbr, 24k tbn, 48 tbc

    Does this shell (bash) script also work with Libav (a fork of FFmpeg)? FFmpeg is not being developed anymore.

    Totally incorrect. People think this is true due to the message they get when they try to use libav's version of "ffmpeg". Neither the message (annoyingly) nor users (understandably) make a distinction between the ffmpeg (the program) and the FFmpeg (the project). It is true that their "ffmpeg" is not being developed anymore, and it has since been dropped from libav since they basically renamed ffmpeg to avconv. It's a controversial mess and I can't imagine libav not foreseeing user confusion from their malworded message and enjoying this side-effect.

    I tried to get the maintainer to re-word the message, but the process was frustrating and the result was unsatisfactory.

    FFmpeg and ffmpeg are very alive.

    See Who can tell me the difference and relation between ffmpeg, libav, and avconv for a quick summary.

    that's why the command is different.

    I have used the script with success to convert a bunch of files but for another bunch it does not work. The error displayed is:

    Input stream #0.2 frame changed from rate:48000 fmt:s16 ch:6 to rate:48000 fmt:s16 ch:2
    [mp4 @ 0x8dc860] Application provided invalid, non monotonically increasing dts to muxer in stream 0: -2 >= -2
    av_interleaved_write_frame(): Invalid argument


    Any ideas what the problem could be? I did a bit of googling and found a thread on this error but not much else.

    Something that can be fixed in the file?
    Thanks

    Edit: Using standard Ubuntu 12.04
