  • Converting mkv to mp4 with ffmpeg sometimes loses video

    9 décembre 2019, par RobertW

    How can I create a universal as possible command line to convert mkv to mp4 ?

    I fixed an issue where sometimes I’d lose audio (I think) and now I’m losing video.
    This is the command I currently use (I’ve used a few, including -analyzeduration 1G -probesize 50M but I always end up with broken videos at some point) :

    if [[ $(pgrep -i ffmpeg) ]] ; then
    
  echo "FFMPEG IS ALREADY RUNNING!"
    
else 
    
  echo "Starting mkv to mp4 conversion...";
    
    for i in /var/www/html/uploads/Videos/*/*/*/*.mkv;
    
      do name=$(echo "${i//.mkv/}");
    
      echo "$name";
    
      ffmpeg -n -i "$i" -c copy -c:a aac -movflags +faststart "${name}.mp4"; rm -v -f "${name}.mkv";
    
    done
    
fi

    Output of running that on the specific videos I’m losing picture on :

    avcodec : Use get_ue_golomb_long() when needed

    get_ue_golomb() cannot decode values larger than 8190 (the maximum
    
value that can be golomb encoded in 25 bits) and produces the error
    
"Invalid UE golomb code" if a larger value is encountered.  Use
    
get_ue_golomb_long() instead (which supports 63 bits, up to 4294967294)
    
when valid h264/hevc values can exceed 8190.
    

    This updates decoding of the following values :   (maximum)
    
  first_mb_in_slice                                36863* for level 5.2
    
  abs_diff_pic_num_minus1                         131071
    
  difference_of_pic_nums_minus1                   131071
    
  idr_pic_id                                       65535
    
  recovery_frame_cnt                               65535
    
  frame_packing_arrangement_id                4294967294
    
  frame_packing_arrangement_repetition_period      16384
    
  display_orientation_repetition_period            16384
    

    An alternative would be to modify get_ue_golomb() to handle encoded
    
values of up to 49 bits as was done for get_se_golomb() in a92816c.
    
In that case get_ue_golomb() could continue to be used for all of
    
these except frame_packing_arrangement_id.
