I followed your instruction and build the ffmpeg in my Ubuntu 16.04 server. I used «Linux with EGL» option. Everything went well and the build was successful.
Then I ran this command with the sample file you gave,
ffmpeg -loglevel debug -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4
It failed with «Segmentation fault (core dumped)» error and here is the debug log,

I have exactly this scenario: FFMPEG mux video and audio (from another video) — mapping issue. I want to mux the video stream from one file and the audio stream from another.
I have renamed the files accordingly and, when trying to follow the answer
ffmpeg -i input_0.mp4 -i input_1.mp4 -c copy -map 0:0 -map 1:1 -shortest out.mp4
or
ffmpeg -i input_0.mp4 -i input_1.mp4 -c copy -map 0:v:0 -map 1:a:0 -shortest out.mp4
I get
Segmentation fault (core dumped).
The same happens when I follow this answer under ffmpeg — replace audio in video, which tries to mux the audio (as a separate file) with the video stream.
ffmpeg -i input_0.mp4 -i a.aac -c:v copy -map 0:v:0 -map 1:a:0 new.mp4
What can I do?

I am using ffmpeg to compress some big images (about 3500 3000×8000 .tiff files) and I am using this command:
ffmpeg -y -framerate 30 -start_number 13244 -i sources/full/full_0%03d.tif -c:v libx265 -r 30 -x265-params crf=22 -pix_fmt yuv420p sources/full_brain.mp4
When I run it on small sets of small images, it works just fine, but on the big images it crashes after a few frames with messages like
Segmentation fault (core dumped) 0kB time=00:00:00.00 bitrate=N/A speed= 0x
I tried compressing fewer files, but it still segfaults. I don’t think that it is a memory problem, since I have 96 GB of RAM and the same amount of swap. Also I tried again the command on the smaller sets and it keeps going just fine.
I am running Ubuntu 14.04.4 LTS (school property, I don’t have sudo privileges) and using the static build.
I have included a log file generated with -report, please tell me if you need anything else.
Also, I just noticed that H.264 encoding through libx264 does not run into the problem, still I would need HEVC encoding if possible.
Thank you in advance,
Enrico
I am running FFmpeg version 4.3.1 — as installed via Homebrew — on macOS Catalina (10.15.7). And this morning I was running a standard FFmpeg command to I use merge MP4 and SRT subtitles:
ffmpeg -y -i input.mp4 -i input.srt -c:v copy -c:a copy -c:s mov_text -metadata:s:s:0 language=eng output.mp4
When it suddenly failed with these lines on the screen:
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:1 -> #0:1 (copy)
Stream #1:0 -> #0:2 (subrip (srt) -> mov_text (native))

This is weird to me since I used the exact same command a few days back — and it the past even — without any issues.
Checking the output file itself only shows the following as content; seems to have died immediately on creating headers for the output file:
ftypisomisomiso2avc1mp4freemdat
Checking a few of my usable MP4 files shows that ftypisomisomiso2avc1mp4freemdat is part of the initial content of those files as well. But the MP4 files that work clearly have headers and binary content past that.
Why the heck this this suddenly happening on such a simple content copy/merge command? This command does nothing more than merge an MP4 video with subtitles without transcoding content and should take less than a second or so to do its job.
The only thing of note is a regularly run brew update and brew upgrade with little to no issues. But I am assuming a recent FFmpeg upgrade caused this issue. Here is the full version output on my macOS machine for reference:

Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
Use -h to get full help or, even better, run 'man ffmpeg'
What can be done to fix this? Simply wait for a new version/patch of FFmpeg to be released to address the issue? Is there perhaps a parameter that can be added to that command to ensure the command works as expected?
