• ffmpeg - extract timecode start metadata from tmcd track to a drawtext filter

  3 mars 2015, par mwjb

  I have a Quicktime file with a timecode track. I’m encoding it to a new video codec and would like to burnin the timecode from timecode track. Setting the timecode manually isn’t an option as this will be used for many files with unique starting timecodes.

  This is the current work-in-progress ffmpeg command. Obviously I need to find a way to extract the metadate:timecode value and have this start the timecode count instead of the manual entry seen below :

  ffmpeg -i infile.mov -y -c:v mjpeg -qscale:v 4 -vendor ap10 -pix_fmt yuvj422p -s 1280x720 -vf drawtext="fontfile=thefont.ttf: timecode='01\:00\:00\:00': rate=24: fontsize=40: fontcolor=white: boxcolor=black: box=1: x=1700: y=80" outfile.mov

  The Timecode metadata is there in the Stream #0:1 track, as read by ffmpeg :

  I came across this post ffmpeg and timecode from movie metadata which appeared to be on the same sort of track as I’m on. Would certainly appreciate some guidance on this. Many Thanks.

• Dreamcast Track Sizes

  1er mars 2015, par Multimedia Mike — Sega Dreamcast

  I’ve been playing around with Sega Dreamcast discs lately. Not playing the games on the DC discs, of course, just studying their structure. To review, the Sega Dreamcast game console used special optical discs named GD-ROMs, where the GD stands for “gigadisc”. They are capable of holding about 1 gigabyte of data.

  You know what’s weird about these discs ? Each one manages to actually store a gigabyte of data. Each disc has a CD portion and a GD portion. The CD portion occupies the first 45000 sectors and can be read in any standard CD drive. This area is divided between a brief data track and a brief (usually) audio track.

  The GD region starts at sector 45000. Sometimes, it’s just one humongous data track that consumes the entire GD region. More often, however, the data track is split between the first track and the last track in the region and there are 1 or more audio tracks in between. But the weird thing is, the GD region is always full. I made a study of it (click for a larger, interactive graph) :

  
  
  

  Some discs put special data or audio bonuses in the CD region for players to discover. But every disc manages to fill out the GD region. I checked up on a lot of those audio tracks that divide the GD data and they’re legitimate music tracks. So what’s the motivation ? Why would the data track be split in 2 pieces like that ?

  I eventually realized that I probably answered this question in this blog post from 4 years ago. The read speed from the outside of an optical disc is higher than the inside of the same disc. When I inspect the outer data tracks of some of these discs, sure enough, there seem to be timing-sensitive multimedia FMV files living on the outer stretches.

  One day, I’ll write a utility to take apart the split ISO-9660 filesystem offset from a weird sector.

• How to save rtsp stream without packet loss by using FFMPEG

  19 juillet 2016, par sumit singh

  I am saving stream of live camera by using FFMPEG. When i am trying to save the video some data packets are loss so the video is not playing properly.I am using following FFMPEG Library

  The command which i am sending is-

   String[] cmd = {"-y", "-i", "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov", "-c:v", "libx264", "-acodec", "aac","-t", time, file_path};
  
   execFFmpegBinary(cmd);

  I am also try this command but the result is same

  String[] cmd = { "-y", "-rtsp_transport", "tcp", "-i",  "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov", "-c:v", "libx264", "-preset", "slow", "-b:v", "500k", "-maxrate", "500k", "-bufsize", "3000k", "-vf", "scale=-1:480", "-threads", "0", "-codec:a", "libfdk_aac", "-b:a", "128k", "-t", time, file_path};

  Here is the log of command output-
