QuTip Example 'bloch-sphere-animation' - video renders blank

15 juillet 2018, par damien murphy.
On MacOSX Using Python3 running the following example code provided without modification : https://github.com/qutip/qutip-notebooks/blob/master/examples/bloch-sphere-animation.ipynb

I get a blank video and no errors.

I have installed libav and ffmpeg so I am not sure what else is missing with any error.

What codec did you install on mac when running these samples ?

Looking at the source of qutip I can see what it is using to render the video : https://github.com/qutip/qutip/blob/master/qutip/ipynbtools.py#L392
```
anim.save(name + '.mp4', fps=10, writer="avconv", codec="libx264")
```
I have avconv on the command line working without errors

This is the debug outout of matploylib.animation

Output for ffmpeg

23 juillet 2018, par Zikry Kickbuttowski

Hello is there a way to output a saved image filename in a format such as yyyy-mm-dd_hrs:min:seconds_imagenumber ? ie (img 2018-07-07_17:34:22_001). And the command has to include fps so that we are able to tweak the fps accordingly. The command also has to churn out images every second. Thanks !
FFMpeg keep audio when adding date/time to video file

19 juillet 2018, par user567424

We have a video file we have recorded and have the ffmpeg script below which adds the date/time to it. However, the output file video loses the audio part. How do we get it to pull that over from the input video file as well, so the audio stays in place ?

ffmpeg.exe -y -i "input.mp4" -ss 00:00:00 -t 00:02:17 -an -vcodec libx264 -profile:v baseline -level 13 -b:v 2000k -vf "drawtext=fontcolor=white:fontsize=16:fontfile="/Windows/Fonts/arial.ttf" :\text=12-07-2018— : box=1:boxcolor=black@0.3:x=(w-text_w-10):y=(h-text_h-5):timecode=’ 14:36:47~;00’:rate=30000/1001" output.mp4
