  • FFMPEG conversion error from MKV to MP4 using libfdk_aac codec

    23 août 2014, par Charlie Brown

    The purpose of doing this is because my "Smart" samsung TV doesn’t play MKV files.

    This thread mentions that there is no need for video conversion, just changing the container might suffice. After reading multiple threads on how to change the container of MKV to MP4, I downloaded and compiled the FFMPEG with libfdk_aac support from here. I tried converting a sample MKV file using this command :

    ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"

    but getting the following errors (copied from command prompt) :

    [hevc @ 0000000000308ae0] Could not find ref with POC 113

Conversion failed!

    Also tried using this command :

    ffmpeg -i input.wav -c:a libfdk_aac -b:a 128k output.mp4

    But this screws up the video quality and I start seeing some bad pixelated patches during the playback.

    Any help would be appreciated.

    Just an FYI : I got this far by reading blogs and posts. I have 0 knowledge about video conversion.
