I'm not sure how one would preserve this automatically but you could easily insert delay with asetpts or adelay: https://www.ffmpeg.org/ffmpeg-all.html#setpts_002c-asetpts https://www.ffmpeg.org/ffmpeg-all.html#adelay I suppose you could write a command that probes the file, assigns the original sta...

FFmpeg in conjunction with a good console could definitely do something like this.

However... at least in my case, it would take probably just as long to write the command as it would to simply use a video editor. But then again the command would be reusable in the future...

You should be able to use -map_metadata:

You'll probably just have to go with using adelay: ffmpeg -re -i udp://224.2.2.8:1008 -map 0:p:40 -vcodec mpeg2video -s 720x576 -r 25 -flags cgop+ilme -sc_threshold 1000000000 -b:v 2M -minrate:v 2M -maxrate:v 2M -bufsize:v 1.4M -acodec mp2 -ac 2 -b:a 192k -af "adelay=0|0"-f mpegts udp://230.0.0.5:10...

I actually own both the Magewell Pro Capture HDMI 4k Plus and the Avermedia Live Gamer 4k, however I haven't attempted to record lossless with either as I don't feel there will be much benefit in quality once uploaded to a streaming service. While I haven't tested lossless capture, I know that someo...

I'm looking to hopefully change the container they store rtbufsize in, if it was stored in 64bit container you could greatly increase buffer size, I'll let you know if I figure anything out. That being said, it's possible that your GPU, CPU, or hard drive isn't keeping up. So regardless of how large...

Is the audio ahead or behind the video?

The amount of threads used is based on the codec, -threads doesn't really work based on everything I've read about it. -rtbufsize is limited by it's container, they're using an INT32 to store the value that caps at 2,147,483,647, been trying to get them to fix this for a while now. You show output f...

Give this a try:
