I'm tying to split mov file to .ts segments with m3u8 playlist.
All is ok except of audio. Audio doesn't work and it seems that ffmpeg ignores audio stream.
This is my command:
ffmpeg -i stepteen2.mov
-c:a aac
-c:v libx264
-an
-map 0
-muxdelay 0
-muxpreload 0
-output_ts_offset 0
-segment_time 2
-segment_wrap 1000
-segment_list_size 0
-segment_list temp.m3u8
-segment_list_flags +cache
-segment_list_type m3u8
-f segment
temp-%03d.ts
After this command I receive 5 ts segments and m3u8 playlist with segment paths list.
If I open properties of segment files there are no any information in Audio and Video tabs (although video works)
This is output:

I'm using ffmpeg as:
ffmpeg -i "video.webm" -c:v libx264 -vf "crop=in_w:in_h:in_w/2:in_h" -ss 00:02:56.000 -to 00:03:02.750 cut.mp4 -y
to get left side of screen to crop out right one, but in result I'm getting uncropped video (both sides present), when I change command to get right side (to crop out left one):
ffmpeg -i "video.webm" -c:v libx264 -vf "crop=in_w/2:in_h:in_w:in_h" -ss 00:2:56.000 -to 00:03:02.750 cut.mp4 -y
everything works as it should (only right side of original video presents in "cut.mp4").
What am I doing wrong?
P.S.

I think you are quite confused about the crop filter options. Here are the descriptions of the first 4 options:
w, out_w
The width of the output video. It defaults to iw. This expression is evaluated only once during the filter configuration, or when the ‘w’ or ‘out_w’ command is sent.
h, out_h
The height of the output video. It defaults to ih. This expression is evaluated only once during the filter configuration, or when the ‘h’ or ‘out_h’ command is sent.
x
The horizontal position, in the input video, of the left edge of the output video. It defaults to (in_w-out_w)/2. This expression is evaluated per-frame.
y
The vertical position, in the input video, of the top edge of the output video. It defaults to (in_h-out_h)/2. This expression is evaluated per-frame.
If you want to halve the width, then the first option must be in_w/2 regardless of which side to crop from.
Height is unchanged, so always use in_h
To crop from left, x offset must match the width, so in_w/2. To crop from right, no pixels are removed on the left edge, so must be 0.
Because no rows are removed, usey = 0.
So to summarize:
Crop the left edge: crop=in_w/2:in_h:in_w/2:0
Crop the right edge: crop=in_w/2:in_h:0:0
I have been using FFMPEG to overlay coloured rectangles on a video. I updated FFMPEG and it no longer works. No error is issued, it just doesn't do the job - the resulting video is the same as the input video. Here's the script:
FFMpeg -y -i Input.mp4 -filter_complex \
"nullsrc=size=1920x1080, \
drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow, fade=in:st=10:d=1:alpha=1, fade=out:st=20:d=2:alpha=1 [tmp1]; \
nullsrc=size=1920x1080, \
drawbox=x=240:y=140:w=300:h=150:t=20:c=red, fade=in:st=15:d=1:alpha=1, fade=out:st=25:d=2:alpha=1 [tmp2]; \
[tmp1][tmp2] overlay=0:0:shortest=1[tmp3]; \
[0:v][tmp3] overlay=0:0:shortest=1" \
Output.mp4
The output video should be the input video with a yellow rectangle added from T=10 to T=20 and a red rectangle from T=15 to T=25, fading them in and out.
The version that was working (3.4) was one that came with an ImageMagick installation. The version I updated it to was 4.2.3. I tried it on various other builds I had lying around and it only works with 3.4.
It seems unlikely that this is a regression so I haven't submitted a bug report. I figure it's more likely that I'm not doing something correctly and 3.4 is more lenient on its interpretation of my command.
Whatever, I prefer to be working with a current build, so I invite comments on what the reasons might be.

There was a bug in the drawbox filter whereby the source alpha pixels would be replaced with the drawbox color's alpha (usually opaque) instead of preserving or blending it. Your command relies on that remaining the case, but I changed that after 3.4 series, so you now have to tell drawbox to replace the alpha for the box pixels.
So,
drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow:replace=1
and
drawbox=x=240:y=140:w=300:h=150:t=20:c=red:replace=1
My source for inputs into FFmpeg is either one AVI file or a concat of many of them. Either way my resulting timelapse file has a long tail of frames that are a repeat of a single frame. It's like a very long freeze frame is resulting on the end of my output file.
I'm on an older Mac Pro so I can't update my FFmpeg. I have a laptop that has a newer version and I get the same there as well. I'm not sure if it's because my source files are AVI or not.

I've read this thread and tried to follow it:
Create time lapse video from other video
Here are some trials I've attempted before, all with the same output:

Am I overlooking something? I'm trying to speed up the inputs into a single file to quickly review incoming security footage. How can I do this without the super long useless tail at the end?
Use
ffmpeg -i 16460021.AVI -vf framestep=15,setpts=N/30/TB -r 30 -an out.mp4
I get an output 1/15th the length of the original. When using framestep=X, setpts should be of the form N/X/TB if you wish to avoid frame duplication. Don't use fps when compressing video duration as it uses old stream duration from before compression (a bug). Skip audio, since that will result in original length.
The output file has the double duration :
Source video duration :00:01:58.88
output video duration :00:03:57.76
（video's duration is double ，audio's duration is correct. So， the video looks like played twice, with no sound in the second half ）
here is the log：

I'm doing some extreme slow motion in ffmpeg on a video, both video and audio track, but can't quite get my calculations correct.
The input video is 00:06:41:00 at 24fps (9624 frames).
I need the output video to be 34:00:00:00 at 24fps (2937600 frames).
I tried these for the video and audio:
setpts=305.237*PTS
atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.807668329177057
However the video overshoots by 00:01:19:08 and the audio I'm unsure, on one player it stops somewhere around 8 hours but on another it just continues. What are the correct formulas?
Also on VLC the video has grey frames between video frames - do I need to interpolate to have continuous video frames?
