abort and missing SIGABRT handling
by Mircea Carausu 28 Feb '20

28 Feb '20

Hello, I noticed av_asser0 macro is extensively used in ffmpeg code... simple grep returns some 11xx hits. Inside this macro abort() call is used. Two questions in my mind: 1. why abort() and not exit() with a err code (i.e. EXIT_FAILURE) 2, if we trigger abort purposely, why not have a signal handler for it and do proper flushing cleanup upon exception detection? Seems SIGABRT (a POSIX signal) does not currently have any handler in ffmpeg. I am sure there are reasons, I am just eager to find reasons behind this... Thank you, Mircea

ffmpeg startup
by tottek＠gmail.com 28 Feb '20

28 Feb '20

Hello, I have a system where ffmpeg is fed with a live stream of camera frames. There are in total 6 processes (6 cameras) being processed simultaneously. When starting up the ffmpeg pipeline, I can see a big surge in CPU, and I'm assuming it is due to ffmpeg processes 'starting' up. Is there any flag for like a 'ramp up' of a ffmpeg process in order to deal with this kind of issue? I could also start the camera recording in a 'staggered' mode, but its desirable for this system to start the recording simultaneously on all cameras. My command line to ffmpeg looks like t his: ffmpeg.exe -y -hide_banner -pix_fmt gray -vcodec rawvideo -f rawvideo -r 60 -s 658x492 -i \\.\pipe\DEV_000F315B978C -c:v libx264 -crf 23 -pix_fmt gray X:\Videos\One_2020T094115.avi -tk

More information about command options
by Jesús Aguilar Armijo 27 Feb '20

27 Feb '20

Dear ffmpeg community, Where can I find more information about the command options? For example, the muxer dash command example is: ffmpeg -re -i <input> -map 0 -map 0 -c:a libfdk_aac -c:v libx264 \ -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline \ -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 \ -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash /path/to/out.mpd But I don't know what is each option (i.e. -bf, -keyint_min, -g... etc) and I can't find in the documentation anything about that. Could you please help me? Thank you, best regards.

amix fills 16Gb memory, ffmpeg killed
by S Andreason 27 Feb '20

27 Feb '20

Hi, I am trying to join 11 video files, each 3 minutes in length. I can get the video rendered correctly, where the audio only lasts 3 minutes from input 0. But when I add the amix filter, it fills 16Gb of memory in 2 minutes and gets it's process killed. The full command line and output, before and after adding ;amix=inputs=11:duration=longest are in this 43Kb text file: https://www.seahorsecorral.org/videos/tests/ffmpeg-killed-16Gb-memory-full.… Is there a better way to write the command? (without resorting to trimming each file, and then using concat filter.) Thank you, Stewart

concat fails in current build with Mobius videos
by S Andreason 27 Feb '20

27 Feb '20

Hi, I am seeing what looks like a regression bug in concat. It stops after the first file, and this only appeared when the input files are from the older Mobius camera. I get the same error trying a version of ffmpeg I built 2019-12-09. But ffmpeg-3.3 from 2017 DOES work, and switching over to the debian9-x64 system, ffmpeg provided from the package manager from 2019-05-21 does work also. Are my compile options causing this? or is the (newest from git) concat filter the issue? There's also a possibility the input files are relevant to the problem, since they are the same as in the memory leak with amix... so I'll include ffprobe at the end, after one fail output and 2 working output. $ cat concat-list-17614.txt file '20170614_0848_driving-Hwy395-CVL_rec12371.mov' file '20170614_0851_driving-Hwy395-CVL_rec12372.mov' file

Acorn Replay files
by Mark Fraser 27 Feb '20

27 Feb '20

I came across some old Acorn Replay files last night and was wondering if ffmpeg/ffplay could handle them. ffmpeg -formats lists D rpl RPL / ARMovie And playing a file with ffplay, plays the audio, but no video.
