• FFMPEG RGB Lossless conversion video

  29 août 2017, par DCDCDC

  I have been experiencing difficulty in finding many answers with FFMPEG documentation, forums and here.
  What I am trying to do is a compress a screen capture video but with just RGB data.
  The steps I am currently taking are ;

  ffmpeg -f avfoundation -pix_fmt 0rgb -r "30" -i "1" -vcodec libx264rgb -pix_fmt rgb24 -crf 0 -t 25 -q 0 -y ~/Desktop/RGB.mkv

  This captures the screen on my mac. To the best of my knowledge, this creates a lossless file and I have compared screen shots that confirm this.
  The next step is where I think I have an issue.
  Because I want to run the compression on raw RGB data I need to convert the MKV to an RGB file ;

  ffmpeg -i ~/Desktop/RGB.mkv -c:v rawvideo -pix_fmt rgb24 -crf 0 -ss 00:00:03 -to 00:02:01 -q 0 -y ~/Desktop/out.rgb

  But here I have pixel variance. My guess is there is a RGB-YUV-RGB conversion happening somewhere but I am not smart enough to work out where.
  If any of you can help I would forever grateful.

  Here is a picture of the two stills side by side that shows the differences ;

  If you need anything more I can post it also.

• RTSP stream to HLS Stream using FFMPEG, Getting Error with newer FFMPEG

  8 novembre 2017, par shaun

  I am trying to take an RTSP stream and convert it to an HLS sTream.

  If I use ffmpeg version N-76684-g1fe82ab
  This command Works just fine.

  c:\temp\ffmpeg.exe -i "rtsp://192.168.249.233:8554/Stream" -c:v copy -hls_time 3 -hls_wrap 10 "c:\inetpub\wwwroot\hls\streaming.m3u8"

  However, if I use a newer compiled version of FFMPEG ffmpeg version N-83779-gfe57bf7cd6
  using the same exact command as above I get the error :

  Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument.

  What am I doing wrong ? I would like to use the newer FFMPEG, but it appears that something broke between them.....

• ffmpeg segments only the first part of my audio file

  30 juin 2012, par hammat

  I'm implementing a http live streaming server to send audio file to iOS devices.
  No problem with Apple's tools, mediafilesegmenter, my files are valid and it works fine.

  I'm trying now to segment the same file using ffmpeg. I've downloaded the last stable version which is the 0.10.2 for now.

  Here is how I try to segment my mp3 file :

  ./ffmpeg -re -i input.mp3 -f segment -segment_time 10 -segment_list outputList.m3u8 -acodec libmp3lame -map 0 output%03d.mp3

  It starts the mapping like expected but finish with only one .mp3 file.

  Did I miss something in the process ?
  Thanks in advance.

  edit

  Ok here is my latest command line :

  ffmpeg -i input.mp3 -c:a libmp3lame -b:a 128k -map 0:0 -f segment -segment_time 10 -segment_list outputlist.m3u8 -segment_format mp3 'output%03d.mp3'

  It still gives me only one file but the file is the hole song, not only one part.
