The audio output looks fine, is the first audio stream is the one you want. Which player did you test in?

I cant get sound to play in VLC, before or after the wrap. The file plays properly in a enterprise software we use .. Avid MediaCentral MAM... the file played fine inside the software, but when I pulled it locally it wont play with sound. I also tried with mpc-hc https://mpc-hc.org/  no luck. as for which stream, I cant tell because they all play nothing on either vlc or mpc-hc (video is fine)

number 1 has audio but it is not understandable, sounds at super speed. playing with `ffplay` plays proper audio... actually audio plays properly in mpc-hc

FFMPEG MXF -> MP4 - Cannot get proper audio on output file

# FFMPEG MXF -> MP4 - Cannot get proper audio on output file

(Asked by: username_0 on 2017-01-09)

I am software developer working on a project that requires my video files to be an mp4 format, as this is what most vendors support. I am trying to use ffmpeg, to rewrap the MXF file, into an mp4. 
Here is the probe. 

Attempting a direct 
ffmpeg -i c:\Users\206420055\Downloads\MAAAAAHVIY.mxf -c:v copy -c:a copy test.mp4

the video works, but the audio appears to be squished into the first few seconds of the video. As well as seeking does not work properly on the video. 
Trying to use libmp3lame as the audio codec, it complains about 

[libmp3lame @ 0000000002d08900] Queue input is backward in time [mp4 @
  0000000003887fc0] Non-monotonous DTS in output stream 0:1; previous:
  1565 375, current: 1564346; changing to 1565376. This may result in
  incorrect timesta mps in the output file.

I have tried a variety of adding -af aresample=async=1000 (and other hertz values), which succeeds in removing the warnings, but does not succeed in fixing the video. 
Does anyone have any ideas what else I am missing? I have tried to map the individual streams to the output as well, with no luck.

> **Comments:**
> **username_1**: Share the full console output of your copy command as text. Add `-report` if you wish.  
> **username_0**: @Mulvya added for your reference.  
> **username_1**: The audio output looks fine, is the first audio stream is the one you want. Which player did you test in?  
> **username_0**: I cant get sound to play in VLC, before or after the wrap. The file plays properly in a enterprise software we use .. Avid MediaCentral MAM... the file played fine inside the software, but when I pulled it locally it wont play with sound. I also tried with mpc-hc https://mpc-hc.org/  no luck. as for which stream, I cant tell because they all play nothing on either vlc or mpc-hc (video is fine)  
> **username_0**: File seeking is also an issue pre-wrap  
> **username_1**: Run `ffmpeg.exe -i c:\Users\206420055\Downloads\MAAAAAHVIY.mxf  -c copy -map 0:a:0 1.m4a`, `ffmpeg.exe -i c:\Users\206420055\Downloads\MAAAAAHVIY.mxf  -c copy -map 0:a:1 2.m4a`, `ffmpeg.exe -i c:\Users\206420055\Downloads\MAAAAAHVIY.mxf  -c copy -map 0:a:2 3.m4a` and `ffmpeg.exe -i c:\Users\206420055\Downloads\MAAAAAHVIY.mxf  -c copy -map 0:a:3 4.m4a` and check which files have working audio.  
> **username_0**: Thanks foryour advice, I have some morning meetings and will get back to you  
> **username_0**: number 1 has audio but it is not understandable, sounds at super speed. playing with `ffplay` plays proper audio... actually audio plays properly in mpc-hc  
> **username_0**: Let us [continue this discussion in chat](http://chat.stackexchange.com/rooms/51519/discussion-between-busturdust-and-mulvya).
