Encoding on the fly satellite shows

[RobbyRally]

Hi!

I use Dvbviewer recordingservice for record my sat tv in TS format. I want trascoding in h264 on the fly. For now i use mencoder but the problem is that i must put a delay that depends from the lenght of show, because my computer PhenonII X3 is capable of 37 f/s the show in Italy is 25 f/s so after few second the trascoding arrive to the end of show and stop it. All the process in automated from Dirmon2. i don't use the Tv in mencoder but the file that recordingervice is recording to hard disk, because for set recording i want use webservice.

I want know if is possible put a "buffer" in mencoder that allows remove delay.

Here there is my bat file.

Thanks! :)


SET mencoderpath="C:\Users\HTPC\Desktop\CREA X264 FILE\Mencoder\mencoder.exe"
SET mkvmergepath="C:\Users\HTPC\Desktop\CREA X264 FILE\MKVtoolnix\mkvmerge.exe"
SET infile=%1
SET secondi=120
SET outdir="E:\REGISTRAZIONI SATELLITE\

This is what pipes are for. With a pipe, the encoder will block until it receives more frames.

How can i add the pipe on mencoder. i'm tryning with this:

"E:\REGISTRAZIONI SATELLITE\A proposito di SchmidtRetequattro.ts" | "C:\Users\HTPC\Desktop\CREA X264 FILE\Mencoder\mencoder.exe" -ovc x264 -x264encopts crf=20:threads=auto -oac copy -o "E:\REGISTRAZIONI SATELLITE\Grand.ts"


but don't work. When launch it windows pop-up appears for select the player for play the show and if i select for example VLC the output is

MEncoder Sherpya-MT-SVN-r30521 (C) 2000-2010 MPlayer Team
SSE2 supported but disabled
No file given

Exiting... (error parsing command line)

If i use this one:


C:\Users\HTPC>"C:\Users\HTPC\Desktop\CREA X264 FILE\Mencoder\mplayer.exe" -vo yuv4mpeg "E:\REGISTRAZIONI SATELLITE\Smallville_02-12_15-58-18_Italia 1.ts" | "C:\Users\HTPC\D
esktop\CREA X264 FILE\Mencoder\mencoder.exe" -ovc x264 -x264encopts crf=20:threads=auto -oac copy -o "E:\REGISTRAZIONI SATELLITE\Grand.ts"

it create a file "stream.yuv" very large 8GB and nothing happen.


also without "-vo yuv4mpeg" nothing happen

Because you're not outputting to the pipe, you're outputting to "stream.yuv", which isn't a FIFO.

But how can i create a FIFO in windows? I'm searching to google a lot but don't find a solution :helpful:
