Tabs in python code about moviepy HOT 9 CLOSED

Thanks for that! It is fixed now. The strange thing is that I have never had any problem in Python3 with these tabs, what is your version exactly?

from moviepy.

I am using python3.3.5 under Mac OSX, installing using Macports.

(I don't know whether MacPorts uses pip, easy_install or something else under the hood. I don't know if it uses six or other packages to mutate Python2 code into Python3 as it does it.)

Ok thanks for the info. Could you try to reinstall and see it it works now? So that I can safely close the issue.

from moviepy.

Quick correction, I originally installed it using pip .

More trouble: old-style print statements in
File "build/bdist.macosx-10.9-x86_64/egg/moviepy/video/tools/segmenting.py", line 47
print "found %d objects"%(num_features)
File "build/bdist.macosx-10.9-x86_64/egg/moviepy/video/tools/tracking.py", line 20
print "WARNING: OpenCV not found: automated tracking not possible"

After fixing that, it installs and imports correctly.

Unfortunately, for my particular movie file, ffmpeg can't determine the duration, and so it chokes at
video/io/ffmpeg_reader.py:215 (where it is trying to find an HH:MM:SS pattern, and ffmpeg puts up
"Duration: N/A, bitrate: N/A") This is from a Raspberry Pi reading off its camera in an h264 raw stream, so some of the encoding may be a bit skanky. Any suggestions?

This sounds like an interesting project. Just to be sure, are you reading from a finite video, or from a video that is still being recorded ? In the first case, what you could try is to rewrite the video with ffmpeg and see if the result has the good metadata (but this might take some time):

ffmpeg -i myvideo.flv mycopy.flv

Otherwise I can also make the duration search optional (and send a warning when a video has no duration). Could you try this and see if it works? That is, replace that line 215 by duration=None, then do things like

myvideo = VideoFileClip("my_rpi_video.avi").set_duration(arbitrary_duration)

Not ideal, but that would be a start.

Does ffmpeg at least find the fps of the video ?

The "print" statements are fixed, thanks for the report.

from moviepy.

I am reading from a file which was previously piped from the raspivid application (over the network).
This permits seeking (so ffmpeg can probe the file and then back up to the start and read.)

Since the compression is not too extreme, it requests a larger -probesize to get enough information to do what it can, but even with an arbitrarily large probesize, it doesn't get the duration.

It returns an FPS of 25. However, this is wrong (actual FPS is 10 in my case).

If I put the duration section in a try/except block, I can use FFMPEG_VideoReader() directly to get sequential frames from the beginning.

However, when I use moviepy.editor.VideoFileClip(), I always get the same frame from fullclip.get_frame(t) independent of how I change t.

Another Python3 change I found (which I needed for the coolTextEffects demo) was

Hi there, sorry to bother you with this old issue, but have you given it a try with the recent version ? There are chances that it may work properly.

No such problem with python2.7.

Thanks for catching that, I corrected it. Now working with Python3 too.
