• Dash timestamp : 41390056 is out of range for mov/mp4 format

  26 octobre 2017, par mike

  I’m trying to convert a aac stream to dash. The issue is that I get a lot of errors as below(though it seems to segment it into multiple files but I get errors on the player too). The question is why do I get these errors and how can I fix it ? If I simply convert "copy" it into to a single mp4 file it works without error.

      ffmpeg -i  "a.mkv" -y -map  0:1 -c:0 copy -min_seg_duration 1000000 
  
  -use_timeline 1 -use_template 1 -init_seg_name init.mp4s 
  
  -media_seg_name  "\$Number\$.mp4s" -adaptation_sets "id=1,streams=0"
  
  -remove_at_exit 0  -f dash -dash 1 
  
  "out/stream.mpd" -loglevel error 

  Output

  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40475608 is out of range for mov/mp4 format
  
  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40764376 is out of range for mov/mp4 format
  
  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40860664 is out of range for mov/mp4 format
  
  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41149432 is out of range for mov/mp4 format
  
  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41390056 is out of range for mov/mp4 format
  
  [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41823208 is out of range for mov/mp4 format

  Copy to a single MP4 works just fine
  ffmpeg -i "a.mkv" -y -map 0:1 -c:0 copy -f mp4 -dash 1 "out/out.mp4" -loglevel error

• Time lapse video using ffmpeg

  18 octobre 2017, par Rich S

  I’m trying to create a time-lapse video from 376 separate images. I want to adjust the framerate to get the best/smoothest result, but my video only includes 343 of the frames in the file.

  I’m using a text file (sequence.txt) to list the files..

  file 'images\20171016T040000Z.jpg'
  
  duration 0.1
  
  file 'images\20171016T040140Z.jpg'
  
  duration 0.1
  
  file 'images\20171016T040320Z.jpg'
  
  duration 0.1
  
  etc...

  And then running

  ffmpeg -safe 0 -f concat -i sequence.txt -pix_fmt yuv420p -y out.mp4

  As far as I can tell, the actual frame-rate of the output file will be 25fps (the default), and the duration of each frame will be 1/10 second. So there will be a few input frames duplicated for each output frame. But this shouldn’t be a problem.

  Why would the video only show the first 343 frames - actually I’ve just noticed that it’s exactly 90% of the required length.

  EDIT

• FFmpeg on Azure Function call running slowly and producing an empty output file

  7 novembre 2017, par The Lemon

  I’m trying to make a function which uses ffmpeg, so far I haven’t been able to get anything other than the -version command to work properly. When I try to run a simple ffmpeg -i {input file path} {output file path} command, the function seems to get stuck for 3-4 minutes (in the process creating an empty output file), then try again and produce the error ’file already exists’. I’ve tried switching between the 64 bit ffmpeg.exe and the 32 bit ffmpeg.exe with the function running as both a 32 and 64 bit function. My code and the associated logs from trying to run the code are included below, if anyone can tell me what I’m doing wrong or how to get the process to work it would be greatly appreciated. Thanks in advance, Cuan

  edit : The process works on kudu with the same files, the output is shown at the bottom. On kudu the process ran in under half a minute, clearly something is causing the function process to hang, if anyone has advice it would be greatly appreciated. Thanks again, Cuan.

  second edit : I tried adding the -y to the end of my command, this works in that it no longer complains about overwriting, but alas it now just hangs twice due to timeout. (output at the bottom)

  edit the third : azure has a way to let you run functions locally, my function ran into the same issues on the local version but : as it turns out the actual processing is done within a few seconds, it just takes forever to decide to write to a file - if you terminate the process manually after the process had been running for 10 seconds the file immediately gets written. Again, any help is appreciated. Cuan.
