What I should do to install it?

[danielballan]

I recently packaged PyAV on 64-bit Linux for conda, so if you use the conda
package manager you could try, conda install -c danielballan pyav.

[w495]

Thanks a lot!

av.audio.frame.AudioFrame.type()

But, I get that for «Basic Demo» example:

[w495@w495yb av-test]$ python3.4 ./test-2.py
Traceback (most recent call last):
File "./test-2.py", line 27, in <module>
    if frame.type == 'video':
AttributeError: 'av.audio.frame.AudioFrame' object has no attribute 'type'
[w495@w495yb av-test]$ 

I guess that it should be:

#!/usr/bin/env python3.4
# -*- coding: utf-8 -*-

import av
from av.video.frame import VideoFrame
container = av.open('/path/to/video.mp4')
for packet in container.demux():
    for frame in packet.decode():
        if(type(frame) == VideoFrame):
            frame.to_image().save('frame-%04d.jpg' % frame.index)

Will you mention this variant for Basic Demo?

Pillow

After that i get

[w495@w495yb av-test]$ python3.4 ./test-2.py
Traceback (most recent call last):
File "./test-2.py", line 12, in <module>
    frame.to_image().save('frame-%04d.jpg' % frame.index)

ImportError: No module named 'PIL'
[w495@w495yb av-test]$

Of course, sudo conda install pillow solves it, but it'll be more convenient to install all with pyav.

Thanks a lot, one more time!

[w495]

A little out of the case

Do you support ffmpeg-2.6? Or only ffmpeg-2.2?
I've try to compile pyav from source for ffmpeg-2.6

May be I have problem with my ffmpeg build, but all except pyav works fine.
Is it a case for new Issue for PyAV?

[mikeboers]

I don't have an immediate answer for the first issue you were having, but my first guess would be a very old Cython. You do also have two versions of FFMpeg, and I honestly can't imagine what that would do. 😛

As far as I know, we support both FFmpeg and LibAV for all versions since late 2012 (so ~0.8 for FFMpeg).

I've updated the basic demo in the docs to reflect the current API, but yours does work find (although I would swap type for isinstance).

[mikeboers]

I don't want to install Pillow or PIL with PyAV, since it is not necessary, and there is the strangeness that comes with that fork. I'll make a new issue about it though.

You do also have two versions of FFMpeg

I have 4 different builds of ffmpeg, and one more from conda.
PyAV works fine with conda's build, and ignores others.

[danielballan]

@mikeboers Yes, I agree that packaging PIL or pillow as a requirement in the conda package would be problematic. Conda has no notion of optional dependencies.

@w495 If you are running PyAV in the conda environment, it is linked against the conda-installed FFmpeg and will definitely ignore all others.
