This is the error message I got the first time I run the command: [h264 @ 0153dc5d4280] sps_id 1 out of range Apparently, the problem has been solved by simply rebooting the PC. Btw, my OS is Windows 10.

This is the command: ffmpeg -i video.mkv -c:v copy -bsf:v h264_mp4toannexb -an -f h264 stream.h264 I am using ffmpeg that was built from the master branch on the 28th of March 2021. I downloaded it from https://www.gyan.dev/ffmpeg/builds/.

[FFmpeg-user] Extraction of H.264 MVC bitstream from Matroska

[FFmpeg-user] the mix filter -- Help, please
As shown below, the mix filter appears to be failing and I don't know why. Can
you help, please?
ffmpeg -i SOURCE -vf "showinfo,split=2[1][2],[1][2]mix=inputs=2:weights=5
5,showinfo" ...
The 'showinfo' information includes:
[Parsed_showinfo_0 ...] n: 0 pts: 0 pts_time:0 pos: 5804
fmt:yuv420p ...
[Parsed_showinfo_0 ...] color_range:tv color_space:bt709 color_primaries:bt709
color_trc:bt709
[Parsed_showinfo_3 ...] n: 0 pts: 0 pts_time:0 pos: -1
fmt:yuv420p ...
[Parsed_showinfo_3 ...] color_range:unknown color_space:unknown color_primaries:unknown
color_trc:unknown
What does "pos" mean?
What does "pos: -1" indicate?
Does "unknown" mean that 'mix' can't handle bt709?
Is there a fix?
Is there a weighted pixel mixing alternative to 'mix'?
I've rewritten the 'mix' documentation (below). Any
input/criticism/opinion/correction is welcome.
Thanks!
Mark.
mix ...Combine 2 or more streams, pixel-by-pixel, via weighted, scaled, pixel
mixing.
Changes TB: No.
Changes PTS: No.
Changes frames: No.
Changes fields: No.
Changes pixels: Yes.
Method: Weighted, scaled, pixel mixing [note 1].
mix=inputs=2:duration=longest:weights=[note 2]:scale=[note 3] ...Defaults.
: :
: first ...End the output at the end of the first
input.
: shortest ...End the output at the end of the shortest
input.
: longest...End the output at the end of the longest
input.
The number of inputs.
[note 1] Weighted, scaled, pixel mixing method:
for each input (1, 2, etc.),
for each frame,
for each pixel (p1, p2, etc.),
(p1)x(weight1)x(scale1) .
(p2)x(weight2)x(scale2) ---.¦
:¦¦
etc. (+)--(+)--> output pixel
[note 1] There can be 1 scale per input, or, if missing, a per-input scale is
applied,
e.g. scale1 = weight1/(sum of all weights), scale2 = weight2/(sum of all
weights), etc.
{was: "Specify scale, if it is set it will be multiplied with sum of each weight multiplied with
pixel values to give final destination pixel value. By default scale is auto scaled to sum of weights."}
[note 2] There can be 1 weight per input (as a list of numbers separated by spaces), or 1 weight for
all inputs, or a partial list. If there are more inputs than weights, the last weight in the list is
assigned to the remaining inputs.
{was: "Specify weight of each input video stream as sequence. Each weight is separated by space. If
number of weights is smaller than number of frames last specified weight will be used for all
remaining unset weights."}
