VLC 1.2.0

I've spoken already about VLC 1.2.0, especially about video, video again and authoring.

However, I haven't spoken about the format supported in VLC 1.2, even if there were some hints in my last post.

Discs and devices


One of the major cool thing of 1.2, will be a (very partial) support for Blu-Rays.

Through the VideoLAN project libbluray, VLC 1.2 should be able to open unencrypted disks and backup folders.

Playback of commercially encrypted disks is also doable, but I won't detail the setup here.


The whole stack of DVD playback libraries has been updated for VLC 1.2.0.

The releases of libdvdnav, libdvdread, libdvdcss should help to playback more recent disks and fix quite a few annoying issues.

Capture devices

  • In addition to quite a few fixes on DirectShow and V4L2 capture modules, QTCapture and QTSound capture modules were added for VLC for MacOS X. Requiring QuickTime 7.6.3, it should allow VLC to play, record and stream any QTKit device.
  • Decklink and DVEO/Linsys/ComputerModules SDI and SDI-HD cards are now supported as input.
  • PulseAudio devices are now supported as input too.

File formats and protocols

Adaptive Streaming

VLC 1.2 should support, at least partially:

  • HTTP live streaming, aka HLS, in both live and VOD mode;
  • MPEG DASH, aka Dynamic Adaptive Streaming over HTTP, in at least 2 profiles.

Those are still under heavy work, help is welcome.

File formats

First, we will have a completely rewritten support for still images playback. The removal of the old fake module should help to make simpler diaporamas with VLC.

Of course, VLC supports new formats, like caf, mtv, awb, f4v, amr, vro (DVD-VR), VDR recordings folders, EBU subtitles (stl). It also supports sid files, from Commodore 64.

The most important improvements to our existent formats should concern Matroska and TS.

A lot of work has been spent on our Matroska demuxer, to handle split-segments and correct seeking. There is still some work to do, but it should be light-year ahead of VLC 1.1.x.

For broadcast and professional people, in addition to the STL subtitles, we have now durations in the Mpeg2 TS files.


Finally, we've worked quite a bit on the Metadata support for most file formats.

APE tags, Ogg tags, seeking in flv, mxf, amr should be better supported. Also, as frequently requested, embedded cover arts in wmv, asf, wma are now correctly detected. The missing bits for cover art support are mainly for MKV and APE formats.

Styles for various subtitles formats are also better supported, especially for simple file formats.


Codecs support has also improved quite a bit, but that's for the next blogpost. :D
