  1. I have about 300 old home movies stored as avi files and a few do not have audio in Plex. I tried converting them in plex but audio was still not available. I have tried converting the files to mkv with the common converters I would usually use including handbrake and nothing seems to see the audio file except vlc media player. I also tried fixing the file with vlc codec avi repair tool but nothing. I tried a tool to convert from avi 1 to 2 and it failed. Any suggestions . Image

    Open the file in Avidemux. Leave video as copy, set audio to either mp3 or aac.
    Output format "MKV muxer" - configure/aspect ratio 4:3
    Save as MKV

  3. The file will not open. I tried other files that I successfully was able to convert to mkv with audio in other software and they will not open either.

    Less than 500MB, that's the site limit. Need a few seconds minimum.

  7. None of the "smaller" files have audio problems.

    OK. You could upload to a file hosting site and put the link in thread. Perhaps mediafire or something similar

    I was going to mention, something I overlooked because I don't use it too often, try FFmpeg, with a command like this
    Code:
    FFmpeg -i PAL_DV_sample.avi -vcodec copy -acodec mp3 -b:a 192k myfile3.avi
    This will just re-encode the audio to mp3

    EDIT I guess FFmpeg doesn't like it either. Perhaps somebody else will chime in on this

  13. ffmpeg batch was one of the programs i tried with multiple preset settings. But i figured I would try the one you mentioned also. thank you for trying. Luckily its only 4 or 5 of about 300 files that have the audio problem Which is weird since they were all created the same way. At least now we have a file posted people can play with. Perhaps someone will take on the challenge.

    When you compare a good file to a bad in mediainfo in text view (for more details) do you see anything different in the audio/video specs?

  15. This one has good audio, updated with correct file. Other than the date I see no differences.

    If you don't mind re-encoding the file, it can be done.
    Since VLC can access the audio, you can use convert/save to capture the audio to a WAV file.
    Here's something quick and dirty

  18. So you used vlc to create the new file. I have already converted most of them all to mkv formatting with aac audio. There were about 5 files that the audio didnt work after conversion. I didnt think about even trying vlc for the conversion. . It looks good on my phone haha. Ill have to take a look when I get home. Thank you.

    The one reason I didn't do a straight conversion in VLC was because the file is interlaced. I couldn't get
    the "deinterlace" option to work in VLC. Converting it without de-interlacing creates a progressive file but with the combing.

    So I saved the audio in VLC, opened the original file in Vurtualdub2, added the new audio, bob deinterlace, save as a new file

  20. Got it, So VLC is used to extract the audio and then combine the audio back into the video file with other software. Ill give it a try with the other files and see how it goes. Thank you for your help.

  21. I was able to successfully convert a file using VLC with both video and audio that works in Plex. Initial results are promising without needing to use any other software. I may need to play with the settings for a lossless conversion of the video but its working. I had forgotten VLC had that capability. I downloaded and tried so many programs and I had the one I needed all along.

    Sounds good, as long as you're able to account for the interlacing. Otherwise, you will see combing when viewed on the TV

  23. The AVI files with PCM audio problems are AVI Type 1 files. You can convert them to Type 2 with DVdate.

    Good spot ProWo -
    we missed the most obvious thing !

  25. I tried another software to convert it to a type 2 but it failed. Ill try this one. I suspected that was part of the problem but was not able to find anything that would work. VLC worked but I lost some video quality. It looks fine on a avg tv but anything larger and it gets noticeable. I tried to copy the video straight across and only convert the audio it only copied the audio and video was black. crossing fingers it will convert

    This worked. Thank you for the suggestion. I was able to convert the file over to mkv after updating it to a type 2 and both video and audio are working.
