 -help                        : print this help message

NB: You can define up to 8192 zones via both the -zones and the -z[qw] options as needed.
I assumed:
Code:
"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -pix_fmt yuv420p -f rawvideo - | "I:\Hybrid\64bit\xvid_encraw.exe" -cq 3 -w 640 -h 352 -csp i420 -framerate 25 -o "E:\Temp\test.m4v"
should work, but it only gives me:
Code:
xvid_encraw - raw mpeg4 bitstream encoder written by Christoph Lampert

xvidcore build version: xvid-1.3.7
Bitstream version: 1.3.7
Detected CPU flags: ASM MMX MMXEXT SSE SSE2 SSE3 SSE41 TSC
Detected 16 cpus, using 16 threads.
   -1: key=0, time=      0, len=      -5 | type=I, quant=  0, len=       0

Tot: enctime(ms) =   0.00,               length(bytes) =       0
Avg: enctime(ms) =  -1.00, fps =-1000.00, length(bytes) =      -1
N frames:      1 frames, size =       0/      0
as output.
The ffmpeg decoding part works fine. (saving to a file instead of piping properly saves yuv data)
I tried '-csp yv12', which didn't help.
I tried adding '-type 0', which didn't help.
I tried adding '-i stdin' or '-i -' but those aborted with 'Error opening input file stdin' and 'Error opening input file -'.

=> Does anyone know how to use xvid_encraw with pipe input?

Cu Selur

Ps.: I know when doing no filtering and the input is avi, directly using xvid_encraw might work, but I'd like to use vspipe and ffmpeg to pipe content to xvid_encraw.

Try with -f yuv4mpegpipe instead of rawvideo.

@Selur:

I guess that xvid_encraw is unable to determine the number of frames of a pipe stream (because it cannot seek to the end of a file and possibly returns a size of 0 bytes), so you may have to add the number of frames explicitly as parameter...

@ChaosKing:

The sources of xvid_encraw don't look like Y4M header parsing is implemented. Even PGM header parsing appears in TODO's.

@LigH: adding '-frames 429'
Code:
"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -pix_fmt yuv420p -f rawvideo - | "I:\Hybrid\64bit\xvid_encraw.exe" -cq 3 -w 640 -h 352 -csp i420 -frames 429 -framerate 25 -o "E:\Temp\test.m4v"
xvid_encraw - raw mpeg4 bitstream encoder written by Christoph Lampert

xvidcore build version: xvid-1.3.7
Bitstream version: 1.3.7
Detected CPU flags: ASM MMX MMXEXT SSE SSE2 SSE3 SSE41 TSC
Detected 16 cpus, using 16 threads.
   -1: key=0, time=      0, len=      -5 | type=I, quant=  0, len=       0

Tot: enctime(ms) =   0.00,               length(bytes) =       0
Avg: enctime(ms) =  -1.00, fps =-1000.00, length(bytes)
doesn't help either. :/

@ChaosKing: yuv4mpegpipe doesn't work either and I agree with LigH doesn't seem like there's code to parse y4m headers.

Ouch, that suxxx indeed
I have just run a fast encoding test... yes, xvid_encraw reads Avisynth files, but does not accept the output(s) from avs2yuv
:-/

Anyway, that's not so unexpected from devilopers who think "nobody will ever need more than 64 zones" and believe Cygwin still is relevant

So, @Selur, your best chance is probably to use Xvid inside ffmpeg...

@LigH: last time I checked ffmpeg doesn't support vhq and some other options. (iirc mbd is similar to vhq) -> I'll check that again just to be sure
So atm. I'm stuck with mencoder for xvid encoding.


Comparing https://www.ffmpeg.org/ffmpeg-codecs.html#libxvid and http://www.mplayerhq.hu/DOCS/man/en/mplayer.1.txt mencoder clearly wins.
A few examples:
Code:
mencoder                         ffmpeg
vhq=<0-4>                      mbd=<simple,bits,rd>
qmin/qmin or I/P/B           qmin/qmax same for all (or just I ?)
quant_intra/inter_matrix   no custom matrix as far as I see
+ some more missing options in ffmpegs libxvid support.
=> It's a pain, but either I find a modified xvid_encraw or I'm stuck with mencoder.

@LigH: since you got an environment setup where you can compile xvid, could you try to compile xvid_encraw with the source from squid_80 http://forum.mediacoderhq.com/viewto...714de0c57709d7 ?
That source seems to define stdin for Windows, but the binary in that thread doesn't seem to work with current xvidcore.dll and the link to the xvidcore.dll which it should work with doesn't work anymore. :/

squid_80 (http://members.optusnet.com.au/squid_80/) also has a 64bit xvid_encraw and a xvid64bit but sadly that doesn't seem to work either.

----

experimenting with the xvid64 and xvid_encraw64 from squid_80:
Code:
.. | "C:\Users\Selur\Desktop\xvid_test\xvid_encraw.exe" -o "E:\Temp\test.m4v"
gives:
Code:

adding '-debug' doesn't work,...

outputs 2 frames, using '-frames X' with X > 2 any I only get 1 frame :/

Hummm, I have tried some modifications on xvid_encraws's code, but they didn't work as expected :-/
According to squid80's mod, adding "include io.h ++ include fcntl.h" apparently is sufficient only if the compiler = MSVC :-/
Evidently I replaced "MSVC" with "_WIN32" so that the recipe could be used by MinGW, but the effectivel «trick» is less simple than I thought.

I've got something working here using this build within yuv4mpegpipe & stdin switches...

Code:
ffmpeg .... -f yuv4mpegpipe - | xvid -type 0 .... -i stdin -o output.m4v

and

First, the good part

Now encraw.exe's -i stdin accepts the outputs from avs2yuv.

Secondly, the bad part :-/

encraw.exe swaps the chroma channels (U & V) when avs2yuv uses the -raw switch and does even worse things when avs2yuv doesn't use the -raw option.

My conclusion: now it should be clear that xvid_encraw is just an EXAMPLE application, not a production-model frontend. Therefore in my humble opinion trying to fix it is not worth the hassle :-/

By the way, and just for a comparison, the Theora fanboys were smarter for creating a frontend based on ffmpeg (ffmpeg2theora), instead of trying to reinvent the wheel.

output from:
Code:
"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -map 0:0 -an -sn -pix_fmt yuv420p -f yuv4mpegpipe - | "C:\Users\Selur\Desktop\xvid-1.3.7\examples\xvid_encraw.exe" -cq 3 -i stdin -w 640 -h 352 -csp i420 -framerate 25 -o "E:\Temp\test.m4v"
looks fine here.
@filler5689: have you tried with '-csp i420'?

Cu Selur

Ps.: strange thing is that '-w 640 -h 352' is still required.

You are right, with "-csp i420" the stupid EXE finally worked as expected.
As I always say, evil devilopers love to choose stupid default settings

Lazy (lack of) coding, granted

Okay, somwhere I mixed stuff up,
Code:
"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -an -sn -pix_fmt yuv420p -f yuv4mpegpipe - | "C:\Users\Selur\Desktop\xvid-1.3.7\examples\xvid_encraw.exe" -type 0 -w 640 -h 352 -csp i420 -framerate 25 -frames 10 -i stdin -o "E:\Output\test.m4v"
doesn't work, but (using rawvideo):
Code:
"I:\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -i "F:\TestClips&Co\files\test.avi" -an -sn -pix_fmt yuv420p -f rawvideo - | "C:\Users\Selur\Desktop\xvid-1.3.7\examples\xvid_encraw.exe" -type 0 -w 640 -h 352 -csp i420 -framerate 25 -frames 10 -i stdin -o "E:\Output\test.m4v"
thought I copy&pasted the command line before, but apparently I didn't.

Argh,... now that xvid_encraw works MP4Box fails me.
A simple:
Code:
MP4Box -add "E:\Temp\2020-10-07@17_16_39_1610_01.m4v" -tmp "E:\Temp" -new "E:\Output\2020-10-07@17_16_39_1610__02.mp4"
gives me:
Code:
[Importer] Error probing E:\Temp\2020-10-07@17_16_39_1610_01.m4v
Error importing E:\Temp\2020-10-07@17_16_39_1610_01.m4v: Filter not found for the desired type
-> I opened an issue for it in the gpac bug tracker (https://github.com/gpac/gpac/issues/1609).

FWIW,
MP4Box - GPAC version 0.8.0-rev1-gc1990d5c-master is what I've been using since "ages ago".

Code:
Filter not found for the desired type
Evidently that happened because the GPAC guys became exceedingly-busy

Okay, muxing to mkv using mkvmerge (v51) doesn't work either,..
Seems like MPEG4 ASP raw streams are not supported by mkvmerge. (https://gitlab.com/mbunkus/mkvtoolnix/-/issues/270)
iirc xvid_encraw doesn't use opendml so file size is limited to 2GB which kind of kills .avi as output for me. :/
So to mux to mp4 or mkv one either needs a xvid_encraw version which supports mkv or one needs to use ffmpeg for muxing,.. :/

MeGUI needs this workaround too: xvid_encraw doesn't create OpenDML AVIs >2GB (and MKV support is marginal, if enabled at all), so it has to create raw MPEG-4 ASP, and then it can't mux it with the optimal tools. Somehow, xvid_encraw is really only a test tool, not a production application.

As already mentioned: It may not even have a YUV4MPEG parser. Hence it doesn't expect any header.

@Kurtnoise: Is your magic available as patch, or may it not even work with GCC?

Yes it works w/ gcc.

Sources including this patch are available in the package linked previously...

I'll suggest this to media-autobuild suite, including their previously applied sed patch for 8192 zones max.
