#Ffmpeg convert frame rate windows mp4

So in my streaming definition mp4 container is good. Usualy "streaming" means "you can start broadcast before last stream frame captured and packed in data stream", but in my case it means "you can continuosly read audio and video streams from container without seeks and cache overrun". Video and audio "mixed" together to make possible seeking by time. That table is only thing that ffmpeg should save while converting. At start it has codec settings and table with stream chunks offsets, durations and sizes. mp4 file, your architecture will be a problem.Ībout mp4 structure. Maybe your pipe:0 test only works because your test file is smaller than the internal memory cache inside ffmpeg? For a big.

The only way to play one, in general, is to download the entire file to memory or local disk. mp4 container is not streamable the file layout requires seek operations. pipe means that stream not support seek operations. Mplayer has -noidx option, i dont think ffmpeg has such ability yet? It's bugtracker here :) I think it's a bug. so ffmpeg tries to seek to the end to get the index. May be exist some way to create unnamed pipe and give handles to processes.Īnyways, to your question, i think the problem is that most indexes are at the end of the file. So server can tranfer different data to every connection trough same pipe.Īlso pipe can be unnamed. So every client, opens different connection to pipe. Here server side creates pipe and listen for incoming connections. ​Qt implements QLocalServer trough named pipes. I don't know way to crate it from cmd.exe but seems it possible from PowerShell using c#. it will help a lot of people if you share the secret or easy way to do it )

Is it possible to create a named pipe just using the command prompt? or do you have to use some kind of program? a lot of people have been asking how to do named pipes on windows. Or somthing like pipe:\\.\pipe\pipename (now not working now) or like pipe:pipename (not working too) Or just add command line argument -noseek or something Or test file seeking abilities with ​SetFilePointer You can use file name to check pipe it or not \\.\pipe\*

Works just fine (not so fast, but works). On some input formats ffmpeg says about bad input.

Then using ​CreateFile in client side open pipe exactly as usual file.įfmpeg -y -vcodec rawvideo -f rawvideo -pix_fmt rgb32 -r 60 -s 800圆00 -i \\.\pipe\pipename out.mkv

Using windows ​named pipes its possible to crate pipe with ​CreateNamedPipe in server side. It's up to 10x faster then standart input (pipe:). I trying to use ffmpeg as fast video codec under windows.
