• Dissappearing characters in youtube-dl, ffmpeg, and windows

  4 juin 2014, par user3407161

  so what happens is that if the video title has a symbol that isn’t supported by your current locale then ffmpeg won’t be able to get to that file properly.

  Here’s one example

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  as you may or may not be able to see, lots of symbols from unicode.

  The problem is that in cmd and ffmpeg, though cmd can see

  ►2 HOURS BEST MELODIC DUBSTEP MIX APRIL 2013◄ ヽ( ≧ω≦)ﾉ

  ffmpeg only sees

  2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ

  This is the exact error message (i’m using youtube-dl)

  [ffmpeg] Adding metadata to 'C:\Music\ToBeDone\2014-06-01\►2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013◄ ヽ( ≧ω≦)ﾉ.mp4'
  
  ERROR: C:\Music\ToBeDone\2014-06-01\2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ.mp4: No such file or directory
  
  ERROR: WARNING: unable to obtain file audio codec with ffprobe

  After some research i’ve determined that by changing the system locale you can change which symbols cmd can support.

  However

  ヽ

  Used to appear as a box in a question mark in United states locale. In japanese locale it appears as it does on your screen right now.

  the problem with

  ◄

  is that even though it’s not appearing as a question mark in a box (it’s appearing as how it should be), ffmpeg (or cmd) can’t detect it properly.

  (Refer back to the error message, i’ll repost it below.)

  [ffmpeg] Adding metadata to 'C:\Music\ToBeDone\2014-06-01\►2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013◄ ヽ( ≧ω≦)ﾉ.mp4'
  
  ERROR: C:\Music\ToBeDone\2014-06-01\2 HOURS DUBSTEP_DRUMSTEP MIX AUGUST 2013 ヽ(≧ω≦)ﾉ.mp4: No such file or directory
  
  ERROR: WARNING: unable to obtain file audio codec with ffprobe

  So as you can see, I think cmd passed on the symbol correctly to ffmpeg seeing from the adding metadata line, but when it actually does the operation ffmpeg loses

  ► and ◄

  Could this be a bug with ffmpeg ? MY workaround so far with incompatible symbols was to change the system locale, but I don’t think i can do that with these two symbols...

  These are the unique characters that i need to have a locale that supports

• Android mp4 Media File Won't play

  17 juillet 2014, par Liron

  I had the same problem as here which I thought was because the files (recorded on iOS) were encoded as .mov instead of .mp4.

  I then changed the encoding mechanism on my iOS app to encode them as mp4, and I’m still seeing the same problem.

  When I load the file with

  File videoFile = ...;
  
  videoView.setVideoPath(videoFile.getAbsolutePath());
  
  videoView.start();

  I get E/MediaPlayer(2069): error (1, -2147483648).

  When I load the file with the following (from the link above).

  Uri uri = Uri.parse(VideoProvider.CONTENT_URI_BASE + Uri.encode(videoFile.getAbsolutePath()));
  
  videoView.setVideoURL(url);
  
  videoView.start();

  I get this in logcat

  07-17 08:05:58.283: W/VideoView(2276): Unable to open content: content://com.companyname.VideoProvider.files.files/%2Fdata%2Fdata%2Fcom.companyname.myappname%2Fcache%2FiX0mXVPxih.mp4
  
  07-17 08:05:58.283: W/VideoView(2276): java.io.IOException: setDataSource failed.: status=0x80000000

  ffmpeg tells me the following about the media file :

  ffmpeg -i media.mp4

  Any idea why this file might be failing to load ?

  EDIT : Seems that this is mostly an issue when running in the emulator, but on a device I seem to have succeeded it getting it to work if I use a SurfaceView and MediaPlayer instead of VideoView.
