Video formats not working

[GoogleCodeExporter]

I use Debian Wheezy 64bit Kernel 3.2.0-4-amd64 - Flowblade 0.12.0

Hello,

I just discovered Flowblade.
Installed successfully from the .deb.

I open it, want to add a video.
"Unable to open invalid media
The file ... is not valid"

Tested on .mpg, .mp4, and h264.
Problem solved when the video is in divx.

I posted the result of the CLI there : (2nd post)
French Forum : http://www.debian-fr.org/flowblade-formats-t48822.html

2 additional problems
When I click on the equalizer button, Flowblade crashes. Maybe it is linked.
I'd like to resize the main window, how can I do ?

Thank you

Ok, some points on these:

1. MLT version is 0.8.0, which is too old for me to take any action on this.
2. Maybe the libav/ffmpeg fork has something to do with this.
3. Have you installed all the codec packages? 
3 .Minimum size for window in Flowblade is 1152x768. Quite of few laptops have 
screen height of 768 leading to a situation where Flowblade is always full 
screen.

You should compile and install repository version of MLT and install Flowblade 
0.14 (just released) and see if these steps solve your problems.

One more thing. Delete file /home/<your_home_folder>/.flowblade/prefs

If that helps for window resize thing, then it's a 0.12 bug, and upgrading to 
0.14 should fix the bug.

I've checked what you said.
1. I can't update python-mlt5 to 0.9.0, because it depends on libc6 >= 2.14, 
that I can't update within distro-upgrading to testing.
2. What to do with libav and ffmpeg ?
3. How to verify the presence of the codecs ?
4. I run a 1280x1024 resolution.

I don't find flowblade 0.14 on this site.

Deleted the file, Flowblade shows up correctly.

Found Flowblade 0.14 repo version.
Installed, launched, tried, same problem. 
When I exit it, I get a segmentation fault at the last line.

Google Code no longer allows adding new downloads. Go to Install Instructions 
wiki in this site and click the down load link there, 0.14 .deb is on my 
Dropbox.

I've already found it and tested it (look at my last post).

I just installed libavcodec-extra-54 from wheezy-backports, and all that seemed 
to concern ffmpeg. Nothing changes.

To see what codecs are available, open from menu Help-> Runtime Environment and 
look at "Video Codecs" and "Render Options" panels.

This may be an MLT issue. Do Openshot or Kdenlive open .mpg, .mp4, and h264. 
files?

You can install them with terminal command: 
sudo apt-get install openshot kdenlive

If they have same problems it's a MLT related issue, else it is a Flowblade 
issue. Actually if KDENlive works and Openshot and Flowblade do not, then it 
might be a packaging issue.

I'm unable to reproduce thw window resize thing. Flowblade does however have a 
heuristic that maximixes window if it was more then 95% of screesize on close 
so this might hit you. There is no "is_maximized()" method available on GTK+ so 
I don't know what else to do. I'm leaving this as is for now.

mpeg2, mp4, h264 codecs are available.

Openshot and KDEnLive don't open those formats either.
It seems to be a MLT issue, and I can't do anything for now :(.

And what do you think about the equalizer button ? MLT ?

I installed Debian 7.2 as a virtual machine and was able to load .mpg and .mov 
files and edit them, so I can't tell what the problem is there. I think MLT 
doesn't work on your system, don't know why.  

The "equalizer" (it is actually tracks and master volume mixer) button does not 
work because  Debian 7.2  MLT is version 0.8.0 and that functionality needs MLT 
0.9.0.

There is an actual bug here: I have code to disable that button if the needed 
"audiolevel" filter cannot be created, but that code is obviously not working, 
so I need to change the method of detection.

I'm leaving this open for now if someone else has similar problems, but I'm not 
taking any other action other then fixing the Audio Mixer disabling code at 
some point.

Ok, thanks for all!
I'll try to wait for the next release of libc6.

Just downloaded flowblade to Mint 17 from the repository, and no media will 
load. 
Openshot works fine.
Checked the video codecs list as above, and all listed.

Downloading Openshot has fixed the problem!
