• cpu.c : Merge ia32 and x86_64 CPU info functions

  cpu.c : Merge ia32 and x86_64 CPU info functions
  After the removal of the OS SSE detection stuff ia32_cpu_info()
  
  and x86_64_cpu_info() became very similar. Merging them makes
  
  sense.

• ffmpeg get info from http stream get bitrate

  19 décembre 2016, par user2631534

  i im using ffprobe and ffmpeg and i im unable to get bitrate from video...i im uisng this command :

  ./ffmpeg -i http://fra1.ddns.net:97/live/test/test/24.m3u8
  
  ./ffprobe -i http://fra1.ddns.net:97/live/test/test/24.m3u8

  And this is what i get :

  Input #0, hls,applehttp, from 'http://fra1.ddns.net:97/live/test/test/24.m3u8':
  
  Duration: N/A, start: 27570.901933, bitrate: N/A
  
  Program 0 
  
  Metadata:
  
    variant_bitrate : 0
  
  Stream #0:0: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc
  
  Stream #0:1: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 139 kb/s
  
  Stream #0:2: Subtitle: dvb_teletext ([6][0][0][0] / 0x0006)

  As you can see i im getting bitrate : N/A and could not get why ?

  server is ubuntu 14,04 64-bit

• Bash Script to get info from ffprobe

  14 novembre 2016, par Alan

  I am trying to create a script to process videos, but I was hoping to get bit_rate, width, and height info from the incoming files so I could better tune the output. The script works when I do the files one at a time, but when I put it into a loop all of a sudden I don’t get any info.

  So this works :

  #!/bin/bash
  
  eval $(ffprobe -v quiet -show_format -of flat=s=_ -show_entries stream=height,width,nb_frames,duration,codec_name input.mp4);
  
  width=${streams_stream_0_width};
  
  height=${streams_stream_0_height};
  
  bitrate=$((${format_bit_rate}/1000));
  
  echo $width,$height,$bitrate;

  This doesn’t when executed from find ./ -type f -regex ".*\.\(mkv\|mp4\|wmv\|flv\|webm\|mov\|avi\)" -print0 | xargs -0 /root/newbatch.sh

  for i; do
  
  eval '$(ffprobe -v quiet -show_format -of flat=s=_ -show_entries stream=height,width,nb_frames,duration,codec_name $i)';
  
  width=${streams_stream_0_width};
  
  height=${streams_stream_0_height};
  
  bitrate=${format_bit_rate};
  
  kbitrate=$((bitrate/1000));
  
  echo $i,$width,$height,$kbitrate;
  
  
  
  done

  I also get an error with the math of bitrate in the loop, but even when I comment it out I still get no results. Since it works one at a time, I am assuming the problem is a bash scripting and nothing to do with ffmpeg / ffprobe.

  That being said, I can do this :

  echo $i,$width,$height,$bitrate;

  and get back

  ./file1.mkv,,,
  
  ./file2.mkv,,,
  
  ./file3.mkv,,,
  
  ./file4.mkv,,,

  So it does get some info back, but it loses the info from the eval statement.
