Strange enough, DivX H264 Decoder is the only codec which doesn't cause a memory leak but when the stream runs for a long time, sometimes DivX decoder crashes as well. I'd prefer to use Microsoft DTV-DVD Video Decoder but it causes huge memory leaks and drops a lot of frames. Many other H.264 decoders I've tried behaves the same way.
It's a Visual Studio 2008 project and all dependencies are included in the zip file in relatively located folders (including the h.264 frames). So, all you need to do is to compile the project, register the output with regsvr32.exe and run the filter with any h.264 decoder you want from GraphEdit or GraphStudio. Example graphs are below.

And they are used from two concurrent threads. You just leak your memory by this inaccurate allocation/deallocation AND/OR letting your code crash on access violation. Debug build of your DLL indicates this by showing you "heap corruption" alert as you run your test. The runtime behavoir might vary with decoders and environment, however this is definitely a severe bug to be fixed.
The difference between decoders you might be seeing is likely to be caused by the fact that some decoders are good with smaller amount of buffers, or reuse them more actively, e.g. prefer to take the same buffer out of a pool rather than picking one by one through all available.
The version is 8.2.0.26, DivX H.264 decoder, a DirectShow filter designed for reading H.264/AVC video. DivX H.264 decoder is a useful video codec you can use for decoding and vieweing H.264/AVC video. Features of the DivX H.264 Decoder 1. H.264 Main, High, High 10, High 4:2:2 profiles 2. Full interlace support (MBAFF, PAFF, mixed) 3....
Today, DivX Inc. released the new version of its famous video codec. Usually, this is utterly uninteresting news, but not this time: Version 7 is actually not an MPEG-4 ASP codec like its predecessors, but a H.264 one, based on the implementation of MainConcept. This makes the codec a lot more interesting, especially since the decoder part is free (as in beer).
All these benchmarks have been run using GraphEdit, a DirectShow filter graph editor. I let DirectShow create a basic playback graph for the input files, removed all audio stuff, replaced the H.264 decoder filter, turned off timing and minimized the video window. This setup makes DirectShow decode the video track as fast as it can. The resulting frame rate can then be easily read from the properties window of the video renderer.
What is H.264?
H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a standard for video compression, and is currently one of the most commonly used formats for the recording, compression, and distribution of high definition video. The JVT was (is) chaired by Gary Sullivan, Thomas Wiegand, and Ajay Luthra (Motorola, USA). From July 2006 to November 2009, the JVT worked on Multiview Video Coding (MVC), an extension of H.264/AVC towards free viewpoint television and 3D television. AVCHD is a high-definition recording format designed by Sony and Panasonic that uses H.264 (conforming to H.264 while adding additional application-specific features and constraints). A specific decoder decodes at least one, but not necessarily all profiles. The decoder specification describes which of the profiles can be decoded. HTML5 is being developed by the HTML5 working group as an open standard to be adopted by all web browser developers. Texas Instruments manufactures a line of ARM + DSP cores that perform DSP H264 BP encoding 1080p at 30fps. This permits flexibility with respect to codecs (which are implemented as highly optimized DSP code) while being more efficient than software on a generic CPU. CPU based solutions are known to be much more flexible, particularly when encoding must be done concurrently in multiple formats, multiple bit rates and resolutions (multi-screen), and possibly with additional features on container format support, advanced integrated advertising features, etc. The H.264 video format has a very broad application range that covers all forms of digital compressed video from low bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding.
Do not forget to add up other third-party H.264 decoders that you don't use such as 'ffdshow Video Decoder', 'Microsoft DTV-DVD Video Decoder' (if you choose DivX H.264 Decoder), 'DivX H.264 Decoder' (if you choose Microsoft DTV-DVD Decoder), 'ffdshow DXVA Video Decoder', 'CoreAVC Video Decoder', 'Cyberlink PowerDVD H.264 Decoder' or any other H.264 Video Decoder you may have and block them.
No extra configuration needed if you choose to use Microsoft decoder. But if you choose DivX H.264 Decoder, go to (Windows 7) Start menu ---> All Programs ---> DivX Plus ---> Codec Settings and enable DivX 8 DXVA capabilities as shown below.
I am trying to get the perfect codec to my HTPC . I am using your supperb DVBViewer V4.3.1.177 (beta) . Also i am making some tests with ffdshow ( rev 3516 date 25/07/2010) and divx pro codec 6.9.2 trial)
With ffdshow dxva decoder but with vc1 and h.264 disabled i get good video , and % of processor is about 20% . With TDT HD channels with less mbits data i get some smalls stops in the video , sat channels in HD and TDT with 12 mbits it is ok . The video it is not deinterlaced but quality it's ok .
VBV (Video Buffering Verifier) defines a specific buffering model. In that model the decoder (player) reads the input data from a buffer. That buffer has a limited size. Also the buffer is filled at a limited data rate. VBV makes sure that the buffer will never run out of data, i.e. it makes sure that there is always enough data left in the buffer to decode the next frame. Therefore VBV forces additional bitrate and buffering constraints on the encoder. It's highly recommended to not use VBV, unless you can't get around it. VBV may hurt the video quality, but it never will improve the quality! Unfortunately hardware players (including mobile devices) may need VBV for proper playback. You will have to look up the particular VBV requirements for each device individually. In particular BluRay has strict VBV requirements. Note that x264's VBV implementation now works just fine with both, 1-Pass and 2-Pass modes. There's no need to use 2-Pass mode for VBV anymore. (See _buffering_verifier for details about VBV)
Many of the files return codecs I recognize (hevc, h264, vp9, mpeg2video, wmv1, etc.) However, confusingly, they also return many codecs that I would think are implementations of MPEG-4 part 2: divx, dx50, fmp4, mp4v, mpeg4, msmpeg4v1, msmpeg4v2, msmpeg4v3, and xvid.
If MPEG-4 part 2 is considered a single video standard, then I would think that although there may be multiple encoders that produce video according to that standard, they'd all be the same "codec". That's clearly an incorrect assumption on my part. But all of the MPEG-4 Part 10 files report as h264 irrespective of which encoder was used. So my first question is what is the distinction between a codec and an encoder, and why do all encoders lead to the same "codec" for MPEG-4 Part 10, but not for MPEG-4 Part 2?
In order to watch Netflix and some YouTube videos, you must have H.264 decoder support. Unfortunately, the H.264 decoder is not free, and therefore is not pre-installed in the free downloadable version of Endless OS.
I have been trying to play h.264 mkv files, without success.
I already installed the restricted formats from Restricted Formats/11.1 - openSUSE-Community, and still no luck. I have no trouble playing DivX or XviD encoded videos. I have installed packages JM, libx264-64, libx264-67 and x264 (which are supposed to be x264 encoder/decoders) and libmatroska.
You should probably also be aware that the h264 encoder used by ffmpeg (x264) supports a lot of features that the QT h264 decoder does not. Be careful when setting the encode options if you need to make sure it is QT safe.
Windows Media Player and Media Center use a new framework called Media Foundation instead of DirectShow when playing certain file formats. In that case they will always use the Microsoft decoders, and not any third party DirectShow filters. Examples of file formats that are played using Media Foundation are: .m2ts, .mp4, and .mov.
