No video on exported image movie as h2.64

[Vadim Peretokin]

I imported a bunch of images as a sequence, added a title one and an audio track. I tried exporting to mp4 h.264 and youtubehd but I always get audio without the video.

Here's how my project looks like, seems everything is fine with it:

http://www.ubuntu-pics.de/bild/28162/screenshot_02_efdM2f.png

and the preview function does work as I'd expect it to be.

it worked fine with ogg for whatever reason.

[Jonathan Thomas (jonoomph)]

I would guess that you are having trouble with the x264 package. How did
you install OpenShot? If you didn't try the .DEB installers, you might want
to give that a try. Do other video formats work?

Thanks,
-Jonathan

I installed from the PPA at first, but as you remember everything was going
wrong - so for this update, I installed all the stuff from the .debs.
ogg is working fine for exporting. mov/mpeg4 worked too.

[GMaq (info-bandshed)]

Hello,

I am also experiencing this bug. libx264 is present on the system and renders correctly from WinFF and also using ffmpeg from CLI. H.264 exported from Openshot in .ipod, .m4v and .mp4 containers will display without video or the player will complain about unknown streams or missing decoders even when other H.264 files from WinFF playback OK (decoders are present on the system). Players used were Xine, Totem GStreamer and MPlayer all with the same result. Other export formats are working fine including libxvid in .mp4. This seems to affect libx264 only.

Using Openshot 0.9.52 running on AV Linux (Debian Testing) with a customized mlt 0.4.6 and Debian-multimedia ffmpeg and libx264 -76. Everything other than H.264 export is working fabulously!

[Vadim Peretokin (vperetokin)]

Yeah, the "x264" binary itself does export properly, should add to that. So
we have the same symptoms.

[GMaq (info-bandshed)]

Well that's two of us!

I should also mention that I installed the openshot-x264 deb package just for kicks and the problem remains the same, which rules out the openshot-x264 package as a solution. I've looked into the export presets .xml files and I don't see anything out of whack there.

Speaking of XML I developed most of the presets for the WinFF project and I don't mean to sound biased but they have potential for much better quality output and in some cases deal better with interlacing, bitrates and HQ switches within ffmpeg. There are also presets already existing for pretty much every device and A/V scenario. If Openshot could import WinFF presets or even allow for further customizing of ffmpeg options in the export advanced dialog it would make for finer tuning and significant quality increases specifically with H.264 since so many portable devices use it (PSP's etc).

Anyway just a thought,

[centralpark (sjhgaffney)]

This bug affects my ability to convert my avchd files into an mp4 using the x264 package. When i convert the video it has audio but no video. I am using a fresh install of Ubuntu 9.04 64bit.

[Jonathan Thomas (jonoomph)]

I think it would be great if we could import WinFF presets! I just haven't
had time to do that yet. =) I'm not sure how to resolve the x264 problems.
It's almost certainly related to x264 or FFmpeg, which some versions leave
out x264 support. If you can use "$ ffmpeg" to convert to h.264 codec, I
would be surprised. I'm not sure the exact syntax, but give that a try, and
let's see what happens. Good luck.

Thanks,
-Jonathan

[Jonathan Thomas (jonoomph)]

Let's try this. Let's see if the MLT command line (melt) can correctly
encode video as h.264. Here is an example command:

$ melt -verbose -profile dv_pal_wide
*/home/jonathan/Desktop/example.avi*-consumer avformat:
*/home/jonathan/Desktop/example.mp4* acodec=mpeg2 ab=128k ar=44100 f=mp4
vcodec=libx264 minrate=0 b=900k

Let me know if this works. Hopefully this will give us some clue to what's
going on.

Thanks,
-Jonathan

OK

Firstly thanks for your attention on this, it is truly appreciated. I am very much looking forward to featuring your hard work in the upcoming release of AV Linux 3.0 coming out by the end of November, I know I personally will use x264 export all the time and am very much looking forward to hopefully assisting you in resolving it.

I am using mlt 0.4.6, I'm not sure if the CLI syntax has changed or not. but I'm not having a lot luck so far, here's the output:

Ooops... if all else fails RTFM!

Apparently the melt CLI syntax has vastly changed from what you originally asked me to input, sorry for the previous post you may want to delete it, here is the updated terminal output:

NOTE: Executing this command now opens a playback window, the output is from the end of the file in both cases.

Jonathan,

I apologize for my hasty assumption that there was an error in your command, I should have known better. I didn't realize it was intended to be one contiguous command, however I've tried slicing it up several different ways based on your example but I'm getting nowhere. Can you see by this example where I'm going wrong?

Sorry about the 2 previous confused and confusing posts.

Hello GMaq

You are using an invalid audio codec for the video codec you are using.

H.264 only valid if with audio codec ac3 or better is aac

Try audio codec libfaac

Helen

[Jonathan Thomas (jonoomph)]

Sorry, apparently I bolded some of the words for emphasis (in my email), and LaunchPad replaced it with asterisks... thus destroying the syntax of the command. Try this command:

$ melt -verbose -profile dv_pal_wide /home/jonathan/Desktop/example.avi -consumer avformat:/home/jonathan/Desktop/example.mp4 acodec=mpeg2 ab=128k ar=44100 f=mp4 vcodec=libx264 minrate=0 b=900k

Let's try this again. =)

[GMaq (info-bandshed)]

@ Helen

Thanks for the tip, I had actually tried libfaac several times as well without any luck so after a while I decided not to stray from Jonathans original script as much as possible.

@ Jonathan,

OK, I'm relieved to know I wasn't totally delusional! OK here's what we have now and it looks like we have a culprit. About 3/4 of AV Linux's video apps depend on the Debian libx264 package, this will not be pretty. The "test.mp4" file created by melt displays without video as per the original problem.

Does Openshot have to use melt exclusively for export? Is there a way to frameserve or pipe the output directly to ffmpeg like Cinelerra does? melt doesn't seem to like the builds of ffmpeg/libx264 some subscribers are using but it is unlikely that the distributions in question are going to change their builds for one program especially when they are working properly from the CLI, and as you know building ffmpeg or libx264 for the end user is no trivial task especially when most distros will only stat their own native builds as a dependency when other ffmpeg dependent program's packages are installed (Avidemux, Cinelerra Kino etc etc etc. In my experience if you build your own ffmpeg you have to build your own libx264 and then every ffmpeg program following has to be built from source to work. Is it possible in python or feasible for Openshot to contain a static ffmpeg and libx264 build within it's own folder?

I can only imagine how frustrating this kind of stuff is on your end! Please let me know how I can assist further. Thanks again for your personal attention on this!

Hmmm,

It seems to want a 'vpre" switch like the newer ffmpeg builds use, I tried this command with vpre presets based on a WinFF iPod preset and it rendered the test .m4v file but there is still no video!?

tester@av3dev:~$ melt -verbose -profile square_ntsc /home/tester/test.avi -consumer avformat:/home/tester/test.m4v acodec=libfaac ab=128k ac=2 ar=44100 f=ipod vpre=hq vcodec=libx264 vpre=ipod640 aspect=4:3 crf=21 bt=256

Hmmm... This does sound tricky. =) OpenShot doesn't actually use "melt" to
export the video, but we use "libmlt", which is the same library under the
hood in "melt". So, if MLT doesn't work with x264, then it won't work in
OpenShot. This might be a question for the MLT mailing list (
<email address hidden>). I do know you can have a static build of
FFmpeg for MLT, but that would be part of the MLT build process. Sorry I'm
not more help. I've learned alot about MLT over the past year, but I'm no
expert packager. =)

Here is a link to the *MLT Build Tips* page. It has an example of a
./configure command with static FFmpeg.

Best of luck,

OK,

I've contacted the mailinglist detailing the issue by paraphrasing my posts here, I will wait to hear back. If a static ffmpeg can be employed is that a change you're willing to make? It would open your app up to virtually any distribution. The whole handling of multimedia apps and libs by Debian and Ubuntu make a strong case for why Linux as a Desktop is doomed unless Debian (and their derivatives like Ubuntu) get their act together. Developers shouldn't have to package and packagers/distributors shouldn't have to fix dependencies for developers. These comments are nor directed at you personally but trying to prepare a pre-packaged multimedia distro for folks from other platforms to try in a user friendly way is so hampered by this "proprietary" type of thinking it is extremely frustrating =(!

[Vadim Peretokin (vperetokin)]

Well, what you do is use frameworks to fix this issue... ala gstreamer.
Frameworks do everything for you, and everyone can integrate with them
(don't have a codec? no problem! totem can get it for you.)

[Jonathan Thomas (jonoomph)]

Glen, I've replied to your message on the MLT mailing list... hopefully it
will bump it up in their inbox. I don't know the solution, but we'll see if
someone helps out soon. =)

Thanks,
-Jonathan

This is also happening to me. Ubuntu 9.10 64bits, Openshot lastest from PPA. Any news / workaround about the MLT / x264 issue? Thanks and congrats for the always-getting-better openshot!

[GMaq (info-bandshed)]

@Jonathan

I haven't forgotten about this issue, my attention has been needed elsewhere. If you received the same e-mail I did from Dan Dennedy it would appear the only solution is to have your export xmls feed a script from libmlt (or melt) to the x264 encoder to tell it what settings to use instead of relying on the defaults. Unfortunately since Ubuntu is heavily based on Debian Unstable you are going to be encountering this problem in Ubuntu soon enough (perhaps already according to the previous post) not just in Debian.

I am still looking forward to featuring Openshot in AV Linux 3.0 which will hopefully be out by the end of November, I look forward to continued progress in it's development. Despite this x264 issue it is certainly an impressive piece of work and I wish to see it continue!

[GMaq (info-bandshed)]

@Jonathan,

FWIW if you are interested to know AV Linux 3.0 has been released with Openshot 0.9.54 included, I have made a note on the website that x264 export is not working in Debian but I still think this is a great app which deserves promotion. If you want to link my site as a LiveDVD way to demo Openshot feel free...if not OK too, it's your call.

Congrats on AV Linux 3.0! I will definitely link to the LiveDVD soon.
Thanks for including OpenShot!

[hva (francesco-hermanitosverdes)]

same bug here with the dev version of mlt and fresh ffmpeg and x264

[hva (francesco-hermanitosverdes)]

maybe this kdenlive bug is related
http://www.kdenlive.org/mantis/view.php?id=1212

[Jonathan Thomas (jonoomph)]

Just a thought: Are these 2 packages installed? libavformat-extra-52 and libavcodec-extra-52

[hva (francesco-hermanitosverdes)]

In my case I just built ffmpeg and x264 from svn and git repos, and configured apparently well.
this is my ffmpeg configuration:

configuration: --prefix=/usr --enable-shared --enable-libmp3lame --enable-gpl --enable-libfaad --enable-libvorbis --enable-pthreads --enable-libfaac --enable-libxvid --enable-postproc --enable-x11grab --enable-libgsm --enable-libx264 --enable-libtheora --enable-libdc1394 --enable-nonfree --disable-stripping --enable-avfilter --enable-libdirac --disable-decoder=libdirac --enable-libschroedinger --disable-encoder=libschroedinger --enable-avfilter-lavf --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3

encoding to h264 with ffmpeg works perfectly well
(e.g. ffmpeg -i INFILE -acodec libfaac -ab 96k -vcodec libx264 -vpre hq -crf 22 -threads 0 OUTFILE.avi gives me a nice video file, with video and audio)

The problem seems to be in MLT, as I can't encode to h264 using melt, even using the suggestions given on mlt mailing list, for example, i tried the following, and the results are always error messages and a file with no video and only audio:

melt -verbose -profile dv_pal_wide INFILE -consumer avformat:OUTFILE acodec=libfaac ab=128k ac=2 ar=44100 f=avi vpre=hq vcodec=libx264 crf=22 bt=256 $(awk '{printf("%s ", $0)}' /usr/share/ffmpeg/libx264-hq.ffpreset)

seems due to recent changes in ffmpeg api and x264. reported the bug to MTL and they're investigating it
