How to encode YUV files into mpeg2 ?

[laminar]

First, thanks a lot for this amazing forum !

I'm trying to find a way to encode YUV 4:2:0 Raster format files (with no header) into mpg2 with a high quality.
Which freeware (or shareware) can I use for that purpose ?
Help would be highly appreciated :thanks:

never tryed myself (don't have such file to test...) but give a chance to Mencoder/ffmpeg :)

several dead links but lots of leads.

I tried but I didn't find any way to read YUV files !

Thanks but I only found dead links or links to YUV players.

I think Mencoder may be THE solution but I don't know how to use it properly.

Emily is more than a viewer.
Good to see you tried.

I managed to convert using emily in conjuction with morgan mjpeg.

here is a stripped down mencoder command:
mencoder 720pparkrun.yuv -demuxer rawvideo -rawvideo w=1280:h=720
-ovc lavc -lavcopts vcodec=mpeg4 -nosound -ffourcc XVID -o op.avi

I had a problem with the clip running to 600 frames when images were only up to ~400 but I don't know if it's a source problem or conversion problem.
First attempt for me with this.
Nothing major anyway.

Thanks a lot for the command line ! this is exactly what I'm looking for...
I'm gonna try and keep you informed of the result.

With the following command line I succeeded to generate a mpeg4 stream (well decoded by VLC but not by WMV10) :
mencoder SA00054.yuv -demuxer rawvideo -rawvideo w=320:h=240 -ovc lavc -lavcopts vcodec=mpeg4 -nosound -ffourcc XVID -o SA00054.avi

I then replaced vcodec=mpeg4 by vcodec=mpeg2. The generated stream is not readable either by VLC or WMV10
I also tried mpeg1 and ffv1 codecs with no success :-(
Any idea bros ?

[45tripp]

don't really know what you want to do,
i'll just say if you're going to mpeg2 you'll obviously want to resize. no?
Anyway some examples.
read up for more.

Thanks Immersion for your examples.
I succeded to generate a mpeg2 stream with the following command line : mencoder SA00054.yuv -demuxer rawvideo -rawvideo w=320:h=240 -ovc lavc -lavcopts vcodec=mpeg2video -of rawvideo -ffourcc MPG2 -nosound -o SA00054.m2v

I don't understand all the options, like "-ffourcc MPG2" !
I need to go more in details, as this tool appears really powerful and complex in the same time.

I work on a transcoder from mpeg2 to h264. For that purpose I want to encode a set of YUV files into mpeg2. It will be a start point for my transcoding feature.

I need to encode Frame and field based streams with a high quality, so I don't really care of the bitrate. How could I force mencoder to use a high bitrate ?
How could I generate a field stream ?
I parsed the encoded stream, it seems that it is IP only (no B frames). Is there a way to force it to encode with B frames ?

Is there a "tutorial for newbies" somewhere ? :)

[45tripp]

Why not just seek out mpeg2 samples?

brames
mencoder SA00054.yuv -demuxer rawvideo -rawvideo w=320:h=240
-vf scale=720:480 -ovc lavc -lavcopts vcodec=mpeg2video:autoaspect:vqmin=1:lmin=0.01:
vqblur=0:vqscale=2:vrc_maxrate=9800:vrc_buf_size=1835:keyint=15:vmax_b_frames=2:
me_range=128:mbd=2:dc=9:aspect=4/3 -of rawvideo -ffourcc MPG2 -nosound -o SA00054.m2v


high bitrate, bframes
mencoder SA00054.yuv -demuxer rawvideo -rawvideo w=320:h=240
-ovc lavc -lavcopts vcodec=mpeg2video:vqscale=2:keyint=15:vmax_b_frames=2
-of rawvideo -ffourcc MPG2 -nosound -o SA00054.m2v


I don't know if mencoder can encode to a field based picture structure.
I've only seen a field based option in procoder.

Is there a "tutorial for newbies" somewhere ? :)
good luck :)
I'm just a noob. read the manual

YUV 4:2:0 Raster format files
Are those raw YUV files? If so you can convert them with AviSynth (RawSource) and QuEnc/HCEnc.

[45tripp]

Good idea, I'd been meaning to try the filter.

http://avisynth.org/warpenterprises/

rawsource("720pparkrun.yuv",1280,720,"I420")

[laminar]

Sorry for not replying before...I was out for a few days.
I'm gonna try what you proposed and keep you informed.

RawSource + QuEnc is a MUST !
I'm used to rip with dvd rebuilder + QuEnc, but I didn't know how to use QuEnc separetly from DVD rebuilder....:thanks:
I will also try HCEnc (I'm not familiar with this one).

Is there a way to use QuEnc in command line ?
I have a lot of Raw files to convert into mpeg2

[laminar]

HCEnc is great also !
Many parameters to set the mpeg output.
I just need a way to generate 100s of streams with a batch command line...

[Guest]

HCEnc has a CLI.

[smok3]

Is there a way to use QuEnc in command line ?
yes there is, check http://forum.doom9.org/showthread.php?t=126636 for my example.

Thanks for the example. I succeeded to use the CLI.
I will try the same with HCEnc as I think I have more parameters available versus QuEnc

[smok3]

you can use ini with hcenc, so the command is like:

"t:\utility\HC021\HCenc_021.exe" -i "in.avs" -o "out.m2v" -ini "t:\utility\HC021\43_progresive.ini"

and ini could look like:
*MAXBITRATE 8000
*PROFILE best
*ASPECT 4:3
*CQ_MAXBITRATE 5.000
*PREVIEW
*MATRIX mpeg

Thanks a lot smok3. I will try that.
