• FFMPEG no audio get recorded from RTSP stream

  22 mars 2016, par Haris

  I am trying to record rtsp stream on HLS format. I need to record both audio and video. Using below command the video and audio get recorded for some stream like a test rtsp stream from Internet rtsp ://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov. Where as for my IP camera it doesn’t work, means the video get recorded but no audio on output file.

  ./ffmpeg -i rtsp://10.0.8.152:554/media/live/1/1 -acodec copy -vcodec copy -hls_list_size 65535 -hls_time 2 "./live.m3u8"

  Here is the command line output for my IP camera while start recording with above command.

• Why does the frame count change when scaling with FFmpeg ?

  22 octobre 2016, par ajmicek

  I use this to scale 1920x1080 H.264 videos :

  ffmpeg -i IMG_1438.MOV -threads 2 -vf scale=-2:600 IMG_1438_scaledTo600.MOV

  And it works great ! But here is my question : most of the time, the frame rate stays exactly the same between the original file and the scaled file. For example :

  $ mediainfo -F IMG_1426.MOV | grep Frame\ rate
  
  Frame rate                               : 29.970
  
  Frame rate                               : 29.970 FPS
  
  Frame rate mode                          : VFR
  
  Frame rate mode                          : Variable
  
  Frame rate                               : 29.970
  
  Frame rate                               : 29.970 (29970/1000) FPS
  
  
  
  $ mediainfo -F IMG_1426_scaledTo600.MOV | grep Frame\ rate
  
  Frame rate                               : 29.970
  
  Frame rate                               : 29.970 FPS
  
  Frame rate mode                          : CFR
  
  Frame rate mode                          : Constant
  
  Frame rate                               : 29.970
  
  Frame rate                               : 29.970 (30000/1001) FPS

  But sometimes, the frame rate increases dramatically :

  $ mediainfo -F IMG_1438.MOV | grep Frame\ rate
  
  Frame rate                               : 25.044
  
  Frame rate                               : 25.044 FPS
  
  Frame rate mode                          : VFR
  
  Frame rate mode                          : Variable
  
  Frame rate                               : 25.044
  
  Frame rate                               : 25.044 FPS
  
  
  
  $ mediainfo -F IMG_1438_scaledTo600.MOV | grep Frame\ rate
  
  Frame rate                               : 120.000
  
  Frame rate                               : 120.000 FPS
  
  Frame rate mode                          : CFR
  
  Frame rate mode                          : Constant
  
  Frame rate                               : 120.000
  
  Frame rate                               : 120.000 FPS

  What should I know about FFmpeg or libx264 or libswscale that will help me understand why this happens ? (Hoping to hear from LordNeckbeard, in particular).

  UPDATE
  To clarify : my video above, the one with the high framerate (120 FPS) output after scaling, plays perfectly before and after scaling with FFmpeg (no sync issues, and 120 FPS is only about 14% larger in file size), I am simply trying to understand why this increase in framerate happens (just a little beyond Mulvya’s note that the framerate stored in the container is wrong).

  From a programming perspective, the initial issue I ran into was that I was using frame= from FFmpeg’s sterr console output to determine progress, which reports erroneous results when the frame count increases dramatically on output ("I’m 372% done encoding ?!") ; I have since read another stackoverflow answer and changed my code to use time=, which appears to be a more robust way for me to display FFmpeg progress. (Also, there is FFmpeg’s -progress option, of course).

  Improving on the original command

  My new command to scale, preserve a useful framerate, and optimize threads :

  ffmpeg -i IMG_1438.MOV -vf scale=-2:600 -r 30 -vsync 0 IMG_1438_scaledTo600.MOV

  Where 30 is the "Maximum frame rate" from mediainfo.

  Thanks to help in the comments, I now know I do not fully understand FFmpeg’s use of three different time bases for timestamps : tbn, tbc, and tbr.
  They were explained by Robert Swain in 2009 and his explanation was also used to answer a Stackoverflow question about tbn, tbc, tbr.

  It sounds to me, as I’m pulling together comments from Mulvya below and Michael Rampe at another forum, that tbr is guessed ; it is frequently but not always the best value to use when changing from a variable to a constant frame rate video.

  Which leaves these 2 questions...

  (1) tbr is incorrect when "field rate and frame rate" differ ? Does this happen a lot ?
  (2) Is -r 30 where 30 is the maximum frame rate reported by mediainfo the best way to do it for most codec/container combinations ? (Or should I only use this method when I am scaling a H.264/MPEG-4 AVC video ?)

• ffmpeg command for faster encoding at a decent bitrate with smaller file size

  14 septembre 2016, par Blair Holmes

  I’m currently using an implementation of ffmpeg on my android app. I’m allowing users to take short videos within my app and then when they upload them to the server, I’m crunching them down with ffmpeg to decrease file size so they’re not passing huge amounts of data over the wire.

  the problem is, it’s taking forever to encode the videos on the android device. These videos usually aren’t longer than 45 seconds and can take 20 minutes to encode. I’ve done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I’m just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

  Here are the two commands I’ve been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it’s encoding for so long :

  ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4

  I’ve tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don’t want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

  ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4

  I’d like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it’s difficult to wrap my head around what I should be doing.

  EDIT : adding ffmpeg output.

  ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4
