Check if updating VLC fixes the issue if not then continue.
First, install the latest version of VLC from. So, before going for the Combined Community Codec Pack, our advice is to try the latest version of the VLC Player.
It provides the full support of the audio and video file and offers the extremely easy solution to trouble related to the UNDF Format. The other solution is that you can try the latest version of VLC Player, which many times, rectifies the error shown in the previous versions. In a way, Combined Community Codec Pack is a simple and highly efficient codec pack, suitable for all kinds of users.
How to Fix VLC does not support UNDF Format? However, there are some instances, where the even if the file is correct in all aspects, faces the same issues, displaying the message “No suitable decoder module: VLC does not support the audio or video format “undf”. The non-availability of appropriate codes required to play the concerned file is one of the reasons for VLC not capable of playing files. The other reason may be corrupted file and even due to some internal issues within the file.
Why VLC gives VLC does not support UNDF format error? The main reason for the VLC does not support UNDF format error is the partial or incomplete download of the file, which we are trying to run. Patent issues aside, HEVC playback within the VLC player can only accelerate demand for HEVC content and browser-based playback, which is a positive for all companies involved in content encoding and delivery.
The answer was “no comment.” While VideoLAN has shipped VLC player with H.264 decode for many years without paying H.264-related royalties, there’s no guarantee that MPEG LA, which expects to announce an HEVC patent pool soon, will take the same approach with HEVC.
'As we are doing software only, not hardware, and we don't make money, we don't license those.' I sent the quote to a contact at MPEG LA, and asked what they thought of Kempt’s assertions. As stated in the article, “European and French law does not consider 'software-only' patents as valid,' said Jean-Baptiste Kempf, president of the VideoLAN Organization, told CNET. What’s VideoLAN’s plan? According to an article in, VideoLAN does not plan to pay HEVC royalties. Rovi, through its subsidiary MainConcept, is a current H.264 licensee, and as a public company, it’s probably safe to assume that they plan to honor whatever HEVC royalties are established. While we don’t know what types of uses will give rise to HEVC royalties, or the costs, it’s expected that integrating HEVC playback into browsers, plug-ins and other players involve a royalty charge, just like H.264 does today. One potential reason for these delays is the lack of a defined royalty policy. For browser-based playback, since HEVC decode isn’t yet integrated into Flash, HTLM5, or the iOS/Android operating systems, streaming HEVC-encoded content is a non-starter. As mentioned at the time, Rovi’s goal with DivX 10 was to “help fuel HEVC content availability and generate demand for playback support to be integrated into consumer electronic devices.” With an estimated installed base of over, the VLC player can further raise the awareness of and increase the demand for HEVC-encoded content, at least for file-based, rather than streaming playback. To be fair, VIdeoLAN wasn’t the first to release a free player with HEVC playback that honor goes to Rovi, which launched with HEVC encode and decode in September. Thus HEVC is a natural, evolutionary step. In addition to extensive platform support, the player also supports an exceptionally broad range of codecs, container formats, and delivery protocols for a range of media types. By way of background, the VLC player is an open source player that’s widely used by most video developers and producers, and by many computer-savvy consumers.
There’s also an interesting intellectual property-related side of the story which I describe below. I tested HEVC playback on Windows and Mac, which works very well. Last week, VideoLAN released, which incorporates HEVC and VCP9 playback on many of the multiple platforms supported by the player, which includes Windows, Mac OS, iOS, Android, FreeBSD, Solaris, Ubuntu, Mint, and multiple flavors of Linux.
