using -vcodec copy I tried outputting as mp4, mkv, fly and mpegts (with and without -bsf h264_mp4toannexb). None of them worked before this patch. They all work after this patch is applied

I could have made this a bit stream filter, but it would do the exact same thing and require extra code / CLI options from the user. Maybe this solution is not ideal for everyone, but currently it is not possible to write an H.264 RTSP stream without transcoding it. This fixes that.
