VSPipe: how to input audio?

Another newbie VapourSynth/ffmpeg question.

I have this basic script and VSPipe set-up for transcoding native HD AVC.mov clips, recorded on a DSLR camera, to UTVideo:

Code:
import vapoursynth as vs
core = vs.get_core()
clip = core.ffms2.Source("Path....../DSCN0968.MOV")
..Other YV12 filtering... 
clip = core.std.AssumeFPS(clip,fpsnum=30000,fpsden=1001)
clip.set_output()
Pipe:
Code:
vspipe Path...../YV12Fullscale.vpy - | ffmpeg -f rawvideo -pix_fmt yuv420p -s 1920x1080 -r 30000/1001 -i pipe: -vcodec utvideo Path....../DSCN0968_VSP_UTVYV12FS.mkv
And equivalent set-up for transcoding to 4:2:2 formats (UTVideo, DNxHD etc)

Code:
import vapoursynth as vs
core = vs.get_core()
clip = core.ffms2.Source("Path....../DSCN0968.MOV")
..Other YV12 filtering... 
clip = core.fmtc.resample (clip, css="422")
clip = core.fmtc.bitdepth (clip, bits=8)
clip = core.std.AssumeFPS(clip,fpsnum=30000,fpsden=1001)
clip.set_output()
Pipe:
Code:
vspipe Path...../YV12Fullscale.vpy - | ffmpeg -f rawvideo -pix_fmt yuv422p -s 1920x1080 -r 30000/1001 -i pipe: -vcodec utvideo Path....../DSCN0968_VSP_UTVYUY2FS.mkv
The clips are recorded with full range (0-255) YV12 luma and this way the scaling is preserved. The native audio is PCM.

My newbie question is - how/where in the pipe set-up can I feed in the source PCM audio path to get the muxed output?

VapourSynth doesn't do audio. If you pipe the video from VSPipe to FFmpeg, you'll need to add the audio from a separate file...

(FFmpeg can take multiple sources, just use "-i" as often as needed)

Yes, that's what I was asking - how to do it ? :

That's what I thought - but taking that first YV12 example again:

Code:
import vapoursynth as vs
core = vs.get_core()
clip = core.ffms2.Source("Path....../DSCN0968.MOV")
..Other YV12 filtering... 
clip = core.std.AssumeFPS(clip,fpsnum=30000,fpsden=1001)
clip.set_output()
If I copy in the audio from the original clip like:

Code:
vspipe Path...../YV12Fullscale.vpy - | ffmpeg -f rawvideo -pix_fmt yuv420p -s 1920x1080 -r 30000/1001 -i pipe: -vcodec utvideo -i Path....DSCN0968.MOV -acodec copy   Path....../DSCN0968_VSP_UTVYV12FS.mkv
I get this:

The pipe worked fine without the audio bit. So something's not right.

or update your ffmpeg like say in your ffmpeg message

Try to specify files streams using -map option .

In your case.

Code:
vspipe -y Path...../YV12Fullscale.vpy - | ffmpeg -i - -i Path....DSCN0968.MOV \
-map 0:v -map 1:a \
-c:v utvideo \
-c:a copy \ 
-y Path....../DSCN0968_VSP_UTVYV12FS.mkv

Thanks, yes that works:

Code:
vspipe -y path......./YV12Fullscale.vpy - | ffmpeg -i pipe: -i path.../DSCN0968.MOV -c:v utvideo -c:a copy -map 0:0 -map 1:1 path...../DSCN0968_VSP_utvideoYV12FS.avi -y
I had this notion that the
Code:
ffmpeg -f rawvideo -pix_fmt yuv420p -s 1920x1080 -r 30000/1001 -i pipe:
part of my original pipe string had to fit in somewhere, but evidently not.

First time I tried it though, I kept getting this message:

Quote:
[yuv4mpegpipe @ 0x1c78ec0] Stream #0: not enough frames to estimate rate; consider increasing probesize
Tried using a longer test clip, but the same thing. This was using ffmpeg 7:2.7.6-Oubuntu0.15.10.1 on Kubuntu 15.10 (64 AMD). Tried again on Mint 17.3 (which I have installed along side Kubuntu). Mint doesn't come with ffmpeg, so I'd installed 7:2.8.6+git1-trusty from ppa:mc3man/trusty-media. Then it worked OK. Only message I'm seeing part way through the encode is:
Quote:
[yuv4mpegpipe @ 0x3a1a7c0] Thread message queue blocking; consider raising the thread_queue_size option (current value: 8)
I need to look at that.

So, yes, thanks for the tip about using -map option. Can't say I completely understand at this point how the -y thing works but I'll try and get my ahead around it. I need to learn these things if I'm going to get any further with ffmpeg.

Cheers.

Edit: Just noticed this recent thread on the same subject:

http://forum.doom9.org/showthread.ph...th+pipe+ffmpeg

So I'm not alone in working through issues like this.
