Christian Hello Christian, I suspect the root problem is this: 1. When FFmpeg (the first call, for transcoding/remuxing), when FFmpeg creates the MPEG TS, where is it putting the "metadata"? The MPEG transport stream protocol is SUPER old, I would be surprised if there were less than a dozen ways to store metadata. 2. When FFplay tries to play back the MPEG TS stream, where is it reading the metadata? Quite likely not the same place. I have no idea. Here are some suggestions: 1. Consider what application you actually want to use for playback, because they will support different types of metadata. VLC, for example, supports VERY LITTLE metadata, which annoys me at times. Even if VLC reads the format for the metadata, it will never show you certain keys, it only shows you a few of the keys. For instance, "Get Info" on VLC usually shows a key "Year" for streaming video, but I know the video has "original air date" (year, month, and day), "copyright date", and possibly other things. And then "Year" is "2018", and that's just not right. That was the encoding year, probably. FFprobe can actually be helpful determining what is going on with things like this if you have no idea (because I have no idea how metadata is stored in MPEG transport streams). 2. MAYBE try putting the -metadata arguments after the "-f rtp_mpegts" argument. Sometimes (often) the order of arguments matters in FFmpeg. I have no idea if that is the case here. Maybe it "processed" -metadata early, when it thought you were going to use a MKV file as the output, and it got that metadata all ready for a MKV file. Then it saw "-f rtp_mpegts" and it threw away the things that go in MKV but not in MPEG TS, and then re-generated some metadata for MPEG TS. This is a wild guess, I would try it. The order of arguments mostly matters when the arguments apply to specific streams (like audio versus video versus the audio commentary). You can specify streams with (colon)(digit), such as -c:v:2, but some arguments do not support that syntax (as far as I know), so you need to put the argument in the group with that whole stream, and the location tells it to go with "2". 3. Before somebody else asks, you might want to include the whole uncut console output, including the "banner" printed by FFmpeg and FFplay that says the configuration options when it was compiled, and so on. I suspect it is not going to be hugely relevant, but you never know. You did say it is the latest Windows build, but these Mailman archives will be around for a long time, and what if you think you are using the latest build because you installed it, but at the hour of typing the command, your PATH variable decided to use an older version of FFmpeg that was lying around somewhere on your hard drive? (There is a nice xkcd comic about having tons of versions of the Python interpreter on one machine, because computers get messy.)
