  libavfilter/vf_fps : Add more fate tests
  These tests cover specific rounding behaviour, to ensure that I don't
  
  introduce any regressions with the rewritten "activate" callback based
  
  fps filter.

• Am I missing a timeout param in FFMPEG ?

  5 mai 2020, par Dave Stein

  I'm running an ffmpeg command like this :

  



  ffmpeg -loglevel quiet -report -timelimit 15 -timeout 10 -protocol_whitelist file,http,https,tcp,tls,crypto -i ${inputFile} -vframes 1 ${outputFile} -y

  



  This is running in an AWS Lambda function. My Lambda timeout is at 30 seconds. For some reason I am getting "Task timed out" messages still. I should note I log before and after the command, so I know it's timing out during this task.

  



  Update

  



  In terms of the entire lambda execution I do the following :

  



  


  • Invoke a lambda to get an access token. This lambda makes on API request. It has a timeout of 5 seconds. The max time was 660MS for one request.

  


  • Make another API request to verify data. The max time was 1.6 seconds.

  


  • Run FFMPEG

  


  



  timelimit is supposed to Exit after ffmpeg has been running for duration seconds in CPU user time.. Theoretically this shouldn't run more than 15 seconds then, plus maybe 2-3 more before the other requests.

  



  timeout is probably superfluous here. There were a lot of definitions for it in the manual, but I think that was mainly waiting on input ? Either way, I'd think timelimit would cover my bases.

  



  Update 2

  



  I checked my debug log and saw this :

  



  Reading option '-timelimit' ... matched as option 'timelimit' (set max runtime in seconds) with argument '15'.
Reading option '-timeout' ... matched as AVOption 'timeout' with argument '10'.


  



  Seems both options are supported by my build

  



  Update 2

  



  I have updated my code with a lot of logs. I definitively see the FFMPEG command as the last thing that executes, before stalling out for the 30 second timeout

  



  Update 3
I can reproduce the behavior by pointing at a track instead of full manifest. I have set the command to this :

  



  ffmpeg -loglevel debug -timelimit 5 -timeout 5  -i 'https://streamprod-eastus-streamprodeastus-usea.streaming.media.azure.net/0c495135-95fa-48ec-a258-4ba40262e1be/23ab167b-9fec-439e-b447-d355ff5705df.ism/QualityLevels(200000)/Manifest(video,format=m3u8-aapl)' -vframes 1 temp.jpg -y

  



  A few things here :

  



  

  1. I typically point at the actual manifest (not the track), and things usually run much faster

  


  2. I have lowered the timelimit and timeout to 5. Despite this, when i run a timer, the command runs for 15 seconds every time. It outputs a bunch of errors, likely due to this being track rather than full manifest, and then spits out the desired image.

  


  



  The full output is at https://gist.github.com/DaveStein/b3803f925d64dd96cd45ae9db5e5a4d0

  


• ffmpeg itsoffset doesnt apply offset to mp4

  26 juillet 2019, par brux

  The following command mixes an mp4 and an mp3 together, keeping the audio from the mp4.

  ffmpeg -i video.mp4 -i audio.mp3 -map 0:v -c:v copy -filter_complex '[0:a][1:a]amix[aout]' -map '[aout]' -shortest out.mp4

  The command works as expected.

  Now I want to offset the mp4 file (both the audio and video stream of the mp4) so that there is a delay of 500ms at the start of the mp4, here is my command :

  ffmpeg -itsoffset 00:00:00.500 -i video.mp4 -i audio.mp3 -map 0:v -c:v copy -filter_complex '[0:a][1:a]amix[aout]' -map '[aout]' -shortest out.mp4

  This doesnt work as expected, the output doesnt have the expected delay of 500ms at the start of the mp4 streams. It appears the output is just the same as the first command I ran.

  The version of ffmpeg I am using is :

  ffmpeg version n4.0-39-gda39990
