Too old, please test current FFmpeg git head before reporting issues.
And when providing the console output, always provide the complete,
uncut console output, not an excerpt.

Question:
If the input format is stereographic and the output format is
equirectangular, what's then the meaning of the h_fov and v_fov parameters?
Do they define the field of view of the stereographic input (that would
make sense),
or do they define the field of view of the equirectangular output (that
makes no sense, because equirectangular should always be 360° x 180°).

They are always used only for output when they make sense, for flat
and stereographic currently.


In my opinion stereographic as input format is useless, if the algorithm 
doesn't know the field of view of the input image.

Re: [FFmpeg-user] 'showspectrumpic' filter: scaling of the frequency axis and fft windows size

2019-09-13 Thread Wolfgang Hugemann 
> Because used fft accepts only power of 2 sizes.

Well, this is clear to me - but what size do you use? My use of the term
'window' may be unclear in this context: I meant the window size for the
fft, i.e. how many samples are used in one fft run? I take from your
code that the window size is two times the output windows width (? ...
rounded to ...?).

...

I already tried scaling the frequency axis with 2^n, i.e. 4096 Hz or
8192 Hz, by that did not help. I think there is something basically
wrong with the scaling of the frequency axis if you use log.

Furthermore, the value that you supply for parameter 'stop' seems to be
divided by roughly 2 (?).

>There is code already for more advanced fft but it is not optimized,
>and thus not yet used.

To my knowledge, all such calculations use fft, i.e. 2^n window sizes,
mostly with about 50% overlap (as you also do for most windows in your
code).

Because used fft accepts only power of 2 sizes.
There is code already for more advanced fft but it is not optimized,
and thus not yet used.

Re: [FFmpeg-user] V360 filter

2019-09-13 Thread Michael Koch 

Paul,



I'm working on dual fisheye output


I've tested double-fisheye input and output and found no problems. This 
can also be used for tilting of 180° single-fisheye images:


set "IN=IMG_077.jpg" :: Input image or video
set "PITCH=0"    :: Rotation angle around X axis
set "YAW=10" :: Rotation angle around Y axis
set "OUT=out.jpg"    :: Output image or video

ffmpeg -i %IN% -lavfi 
"pad=w=2*iw:color=darkgreen,v360=input=dfisheye:output=dfisheye:yaw=%YAW%:pitch=%PITCH%,crop=w=iw/2:x=0" 
-y %OUT%

[FFmpeg-user] 'showspectrumpic' filter: scaling of the frequency axis and fft windows size

2019-09-13 Thread Wolfgang Hugemann 
Today, I have been experimenting with the 'showspectrum' filter, mostly
with 'showspectrumpic'.

I think there is a bug in the log scaling of the frequency axis if (and
only if) it doesn't start at zero: The ratios of the frequency axis'
labelings is not constant, they grow with larger values.

I had a quick look at the source code and gained the impression that the
fft windows size is based on the height of video created (?). At least
it cannot by specified in the filter options.

Kind regards

Re: [FFmpeg-user] ffmpeg to stream an already h.264 encoded stream

2019-09-13 Thread Verachten Bruno 
As for the filename, I used a bash variable, and it worked. I should have
thought about it earlier.
I haven't found yet how to keep the bitrate and size, and still have to add
delay for the sound.

I tried to play back the file on another machine (Windows this time), and
it doesn't work.
It stays on the first part of the video, ignoring the rest, and giving
errors when trying to fast forward:
