Hello, Simple question. I've found out that ffserver is no longer maintained. As far as the project goes, tentatively need these requirements. 1. streaming 2 video cameras simultaneously - both of which are usb cameras. 2. 1280x720 30fps video 3. Able to be run on Pi4 with 2GB of memory. Tentatively looking for the following features - able to access stream to record the video and take snapshots on Android tablet. So what server should I be looking at? Thanks for any help you can provide.

Even though I don't believe that is the root cause, I was going to explain to you how to strip metadata using ffmpeg.

The resulting file may also be fixed for other reasons than the metadata, e.g. reconstruction of some index or something like that, which the original may be missing. (Guessing here - just go try.)

Is there a way to avoid that? This means you are actually not splitting (because that can't easily be done with actual MP4 containers), but remuxing. ffmpeg can't exactly reconstruct the original container, as explained in my response in the other thread. As Carl Eugen worte: Always when describing such as issue, please remember to show us the actual command line you used, and the command's complete, uncut console output.

Re: [FFmpeg-user] How to use ffmpeg in batch mode?
Hi. If you are only changing the container and don't want to transcode the contents, be sure to add -c copy in the ffmpeg line of the example (haven't tested it but it seems fine), so it looks like this: ffmpeg -i %IN% -y -c copy %OUT% Br.

To take up your example: $ dd if=inputfile.ext bs=1M skip=4 of=outputfile.ext But if you're doing this with a video file, the result can be unplayable. This depends on the format of the video file, and possibly on its content. If you want to use ffmpeg to split a file, please understand that ffmpeg always demuxes and remuxes the video content, and usually cannot preserve the exact original container.
