• No Working C Compiler Found

  1er décembre 2014, par Rajendran Ambika

  I just downloaded it from here to try it :

  http://www.videolan.org/developers/x264.html

  I ran ./configure. It complained that I didn’t have an assembler and suggested I ran ./configure —disable-asm. Then all seemed to compile OK.

  How did you install gcc ? From the repositories ?

  After i check the GCC version by using (gcc —version) command in terminal. The log is

  i686-apple-darwin11-llvm-gcc-4.2
  
  (GCC) 4.2.1 (Based on Apple Inc. build 5658)
  
  (LLVM build 2336.11.00)

  how can i solve this issue ..? I want to make compile and install.

• Player for Android SmartPhone and Android TV, live stream using m3u/m3u8 playlist with MPEG-2 TS channels

  30 mai 2016, par ot0

  I want to have a player (like IPTV) that can play the .m3u playlist channels.
  I have found ExoPlayer should support live-streaming. I want to be able to see the code because I want to add the player inside my own App and embed in my own GUI.

  I downloaded the open source github project of exoplayer github.com/google/ExoPlayer and appended the URL for our .m3u playlist (containing mpeg2-ts channels) in the demo but unfortunately it couldn’t play. Inside the Samples.java I added a Test channel :

  public static final Sample[] HLS = new Sample[] {
  
   new Sample("Apple AAC media playlist",
  
          "devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/gear0/"
  
          + "prog_index.m3u8", Util.TYPE_HLS),
  
      new Sample("Apple ID3 metadata", "devimages.apple.com/samplecode/adDemo/ad.m3u8",
  
          Util.TYPE_HLS),
  
  
  
      ....
  
  
  
      new Sample("Test", "ipaddress.com/channels.m3u", Util.TYPE_OTHER)
  
    };

  I also tried to just paste the URL of one of the mpeg2-ts channels from the playlist but it didn’t work either

  The .m3u looks like :

  #EXTM3U
  
  #EXTINF:-1 group-title="Random" tvg-logo="xx.com/pic/channel1.jpg",Channel1
  
  ipaddress.com:7777/channel1
  
  ..
  
  #EXT-X-ENDLIST

  Does anyone have some recommendations ? It is not possible to play IPTV encapsulated in MPEG-2 TS using ExoPlayer ? If not, do we have alternatives ? I am mostly for an open source project where the player is already implemented so that I only need to add visual elements inside it. Otherwise API to other apps will also be useful

  After commit I burn subtitles into video :

  ffmpeg -i video.avi -vf "ass=subtitle.ass" out.avi

  My goal is to show commit date for 10 second at the start of movie. This should be done automatically.

  1) It can be easily done with by modifying subtitle.ass itself, but I can’t do it after commit and there are other reasons.

  2) It can be done by ffmpeg from command line : How to use ffmpeg to add a text to avi video ?

  Problem is that in this case text will be shown for the whole lenght of movie.

  3) I can copy *.ass file to temporary directory, insert date, render and delete *.ass file.

  Is there a simpler way ?
