I hope that I am doing this right, the format of sending emails is a little different then posting on other forums that I have reached out to in the past. I have been using ffmpeg for only a short period of time and while it has worked great, I am running into an issue and need a little assistance. I have been moving my movies to a drive and then I will stream to the TV's in the house. Unfortunately due to the devices that I am streaming the movies with, I am limited to AC3 and not True HD or even DTS. So I have been converting all of the audio in my movies to AC3 with ffmpeg. Below is the command that I have been using
ffmpeg.exe -i myvideofile.mkv -map 0 -vcodec copy -scodec copy -acodec ac3 -b:a 640k myvideofilewithAC3.mkv
As I said this has worked great for nearly all of my movies, but I am getting an error with several of them. The error reads "Time stamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your time code to set the timestamp properly."
While I am pretty new to this, I am confused as I am coping the video with no changes and yet there are issues. I am also confused as to why most of my movies not have any problems, but a several do? Most important question is how do I fix this. I have searched online and I haven't found anything that helps.
