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

I'm currently using the command
ffmpeg -i mainvideo.mp4 -vcodec libvpx -i myoverlay.webm -filter_complex "overlay = 5:5" done.mp4
To overlay a transparent webm on top of my main mp4. But for some reason the output video is frozen for the first 1~ second but the audio is completely fine.
I've tried this command with other videos and it works sometimes but most of the time the first few frames seem frozen
Edit.
I have two main mp4 files, broken_source.mp4 and working_source.mp4. Putting the overlay on broken_source results in the output having the first 1~ second of video frozen (audio completely fine) but putting the same overlay on working_source.mp4 is perfect and has no issues
Logs for putting the overlay on working_source:
ffmpeg -i working_source.mp4 -vcodec libvpx -i chat.webm -filter_complex "overlay = 0:0" working_complete.mp4

I am trying to down scale a video from 607x1080 to 440 width with the height automatically being calculated using the following command. It does scale the video but not to the specified dimension. The video is scaled to 216x384 even though the output below indicates 440x384.
ffmpeg -i video.mp4 -vf scale=440:-2 -c:v libx264 -c:a aac -y video-out.mp4

I did some searching and learned this may be an issue scaling with libx264 codec and the input width being an odd number? If so, is there a workaround so get the video to scale to the specified size? Thank you.
The scaling is "correct", but the video has a pixel or sample aspect ratio below 1 (27:55 ~= 0.491) so the video's effective display ratio is not the same as the ratio of width to height of the stored pixels.
Use the -vf expression below
-vf scale=440:2*trunc(ow/dar/2),setsar=1
Besides the scale, I reset the SAR to 1.
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 am trying to find a way to get FFmpeg to return a machine readable output. basically, I just want to know if video conversion was successfull.
I am calling FFmpeg from go code.
output, err := exec.Command("ffmpeg", "-i", source, "-vcodec", "h264", "-acodec", "aac", "-strict", "-2", destination).CombinedOutput()
The above code executes this command :
ffmpeg -i /tmp/pitchVideo-1494844705-102.mp4 -vcodec h264 -acodec aac -strict -2 /tmp/1494844705.mp4
I get the following output:

Edit 1: Maybe I can just check if new video file was generated. But I don't know if that is a dependable way to do it.
Add -progress url to the ffmpeg options, then you will get progress information (machine readable key=value format) every second. You can specify filename, tcp://, http:// etc. as the url.

I tried with other stackoverflow questions but none of them worked. Also I think it is partially because the trim timings are mixed. That is start time can be anywhere between 0-end. When I make it strictly increasing it is working fine.
Add a fifo filter at the end of each of the video filterchains.
i.e.
[v0]trim=start_frame=1:end_frame=142,loop=1:1:1,setpts=N/FRAME_RATE/TB,fifo[0v];
Although probably not necessary, you can add afifo to the end of audio chains as well.
