First time x264 user question

[iMaiden]

I am running ubuntu 8.10 and have gotten this far:

x264 --output tester.mp4 test.mp4 480x360

which produces this output:

yuv [info]: 480x360p 0:0 @ 25/1 fps (cfr)

Here is my question:


The input file is 3 mins in length the output file is 3 secs. The output just plays snow.

The aspect ratio of the input is also 480x360

Am I missing something simple here? Any assistance is appreciated.

[sneaker_ger]

There's either something wrong with your file or you've found an error in x264. Test the latest revision and upload your file - if you're lucky some of the x264-devs will take a look at it.

/edit: And try dropping the "480x360".

[LoRd_MuldeR]

Appending the resolution of the video is only needed for "raw" YUV video and even that only if the YUV data isn't stored in a YUV4MPEG (.y4m) container.

Not sure, but maybe appending the "480x360" caused x264 to misinterpret your MP4 file as "raw" YUV data? As suggested by sneaker_ger, try dropping that part.

x264 can determine the resolution of MP4 files automatically. Just make sure you have a build of x264 with FFM2 support enabled...

[Boolsheet]

Yep, we need to know your x264 version and what it supports.

Check the version with:
x264 --version

x264 --help
gives you something like:
x264 core:92 r1523 25ca5b0
Syntax: x264 [options] -o outfile infile [widthxheight]

Infile can be raw YUV 4:2:0 (in which case resolution is required),
or YUV4MPEG 4:2:0 (*.y4m),
or Avisynth if compiled with support (yes).
or libav* formats if compiled with lavf support (yes) or ffms support (yes).
Outfile type is selected by filename:
.264 -> Raw bytestream
.mkv -> Matroska
.flv -> Flash Video
.mp4 -> MP4 if compiled with GPAC support (yes)

[Dark Shikari]

Your x264 was compiled without support for any video decoder, so all it's able to do is interpret your (compressed) file as raw video. This is expected behavior.

Recompile your x264 with some input module.

Not sure, but maybe appending the "480x360" caused x264 to misinterpret your MP4 file as "raw" YUV data? As suggested by sneaker_ger, try dropping that part.There's no misinterpreting going on; the file is raw YUV, as x264 sees it, because the version you're using doesn't have support for anything else.

[iMaiden]

Here is how I compiled:

sudo apt-get install libavcodec-dev yasm libavutil-dev libpostproc-dev libbz2-dev libgpac-dev libxvidcore4-dev
./configure --enable-pthread --enable-avs-input --enable-mp4-output --enable-ffms-input --enable-lavf-input --prefix=/usr --enable-shared
make -j 4
sudo make install

Here is what happens if I do not specify the res:

x264 --output tester.mp4 test.mp4
yuv [error]: rawyuv input requires a resolution.
x264 [error]: could not open input file `test.mp4' via any method!

Here is the version info:

x264 --version
x264 0.92.1523 25ca5b0
built on Apr 7 2010, gcc: 4.4.1

[Dark Shikari]

What does the output of configure actually say though? And what about x264 --help, where it tells you whether or not you compiled with lavf/ffms input?

As I said.

As an Ubuntu user you might find this guide (http://ubuntuforums.org/showthread.php?t=786095) useful.

You're missing libavformat-dev

I am able to do a straight encode. Can someone tell me the most effective command line way to append the audio and resize under linux?

TIA

Currently x264 doesn't handle audio at all. Furthermore video filters (like resize) aren't available in x264 yet. However either MEncoder or FFmpeg should be able to do both under Linux.

[iMaiden]

I was able to complete my task via ffmpeg but feel that I have lost some of the "control" over the compression process and have returned here with another compile error:

sudo apt-get remove ffmpeg x264 libx264-dev

Any Ideas?

As Dark_shikari said:

Follow this guide...

[iMaiden]

That is the guide that I was following. The problem with it is that it does not specify MP4 output enabled. I need to compile x264 with mp4 support.

[kemuri-_9]

sudo apt-get install libgpac-dev
and you can remove it when done, since x264cli uses the static library.

[iMaiden]

Thank you. That allowed me to compile for mp4 output. But now I am getting this error:

./x264 -o t.mp4 ./test.mov
x264 [error]: could not open input file `./test.mov' via any method!

Any suggestions?

[RunningSkittle]

did you compile with ffms/lavf support?

[iMaiden]

Is there a special trick to compile with these options? I config with the following line:

./configure --enable-pthread --enable-avs-input --enable-mp4-output --enable-ffms-input --enable-lavf-input --prefix=/usr --enable-shared
Platform: X86_64
System: LINUX
asm: yes
avs input: no
lavf input: no
ffms input: no
mp4 output: yes
pthread: yes
debug: no
gprof: no
PIC: yes
shared: yes
visualize: no

You can run 'make' or 'make fprofiled' now.

[Dark Shikari]

You need ffmpeg (and associated libs/dev headers..) installed if you want x264 to be able to decode arbitrary inputs.

[iMaiden]

When I compiled x264 it listed "ffms input: no" but lavf input as yes. I am able to run the compressor but will this be an issue for me in some way that I do not understand?

[Dark Shikari]

When I compiled x264 it listed "ffms input: no" but lavf input as yes. I am able to run the compressor but will this be an issue for me in some way that I do not understand?ffms tends to be a bit more reliable at times, and lavf doesn't show the full progress indicator, but otherwise it should work fine.

[qyot27]

Is there a special trick to compile with these options? I config with the following line:

./configure --enable-pthread --enable-avs-input --enable-mp4-output --enable-ffms-input --enable-lavf-input --prefix=/usr --enable-shared
--enable-pthread, --enable-mp4-output, --enable-ffms-input, and --enable-lavf-input are autodetected if you've already installed them (and pthreads come standard anyway). You don't need to specify them. The reason it won't autodetect ffms2 is because you haven't compiled and installed it.

--enable-avs-input is a Windows-only option, so it's irrelevant on Linux. Unless suddenly that's changed.


The proper steps are below. I've amended them in parts from the guide on Ubuntu Forums (and my own instructions for Karmic I posted on page 23 there - er, page 90...I always forget that I have these types of forums set on 40 posts per page), since I don't need a lot of FFmpeg's extras. But this gives the bulk of what's needed.
svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
svn checkout http://ffmpegsource.googlecode.com/svn/trunk/ ffms2
git clone git://git.videolan.org/x264.git
mkdir ffms2_build
cd ffmpeg
./configure --prefix=$HOME/ffms2_build --enable-gpl --enable-version3 --enable-postproc --enable-pthreads --disable-encoders --disable-muxers --disable-debug --disable-network --enable-libfaad --disable-decoder=aac --disable-hwaccels --disable-filters --disable-indevs --disable-outdevs --enable-runtime-cpudetect
make
make install
cd ../ffms2
./configure --prefix=$HOME/ffms2_build PKG_CONFIG_PATH=$HOME/ffms2_build/lib/pkgconfig
make
make install
cd ../x264
PKG_CONFIG_PATH=$HOME/ffms2_build/lib/pkgconfig ./configure --enable-shared
make
sudo checkinstall --pkgname=x264 --pkgversion "2:0.`grep X264_BUILD x264.h -m1 | cut -d' ' -f3`.`git rev-list HEAD | wc -l`+git`git rev-list HEAD -n 1 | head -c 7`" --backup=no --default
make distclean
cd ../ffms2
make uninstall
make distclean

cd ../ffmpeg
make uninstall
make distclean

As long as you've got the dev files for faad2 and gpac installed, then everything should be properly enabled.

[iMaiden]

I believe that I have compiled the program correctly. My first test is lossless. I am using this command:

x264 --qp 0 -o output.mp4 test.mov

Which produces a completely white mp4.

There seems to be no errors:

Any suggestions?

[Dark Shikari]

How are you viewing the mp4?

[iMaiden]

Quicktime. I tried to open it with another player and it worked. Can you tell me why the quicktime player would have difficulty?

[Dark Shikari]

Quicktime. I tried to open it with another player and it worked. Can you tell me why the quicktime player would have difficulty?Quicktime doesn't support lossless H.264.

[iMaiden]

I have switched viewers and now I am looking for tools to analyze what x264 is actually doing. I have found h264Visa which seems pretty good. Does anybody know other tools? I am open to any operating system but prefer linux.

(also doesn't support lossless fyi)

[iMaiden]

I need to add multiple watermarks on the same encoded output. e.g. (editor, DP, sound) Does anybody know the best way to achieve this?

[J_Darnley]

avisynth would be the easiest

[iMaiden]

Is it even possible to watermark after the encode?

[poisondeathray]

Is it even possible to watermark after the encode?


No; unless you do something like soft sub, but I doubt that's what you want

[iMaiden]

Now that I can actually encode my test footage I would like to actually encode my source which is a dpx sequence. I am having a difficult time finding information on importing from anything other than tiff and want a clean work flow. Am I missing something easy here?

[kieranrk]

ffmpeg has a dpx decoder.
