Sample_decode with a MPEG4 movie from iOS returns error code -3 in pipeline_decode.cpp (414)

[it doesnt post my message - just the heading :-(]

I am trying to use sample_decode on a H264 movie created on an iOS device (using AVFileTypeMPEG4, AVFileTypeQuickTimeMovie and AVFileTypeAppleM4v). I tried with and without the hw option. I tried on an i7-2600 and i7-860 processor. I am using Windows 7 - enterprice. Any help is much appreciated

And,I am using the Media SDK 2012 with Visual Studio 2010 Ultimate.

Thanks

Hi,

Seems you may be trying to use MVC decode on an H.264 file?

Anyhow, could you please provide the exact command line parameters you used to decode the stream and preferably also the video stream itself?

Regards,

Petter

I am using

sample_decode.exe -hw h264 -i 0.mp4 -o data.yuv. I will upload the sample video shortly.

Here is the movie file. Hope the system does not process it?

Related question: My system has a i7 2600 processor and Intel Desktop board DP67BG and AMD graphics card. As far as I can tell, the processor has a builtin Intel HD graphics but I can't access it via the BIOS. The BIOS only sees the AMD GPU. I cannot install the Intel HD graphiics driver either (complains that "This computer does not meet the minimum requirements for installing the software". Will I be able to use the hw acceleration on this computer?

Hi,

The reason you cannot decode the file is two-fold.
(1) Media SDK does not have any support for container handling (such as the mp4 format). The SDK only operates on elementary video streams. Please refer to the Media SDK "Media Developers Guide" document (chapter 3), part of the SDK package for more information on this topic.

(2) For HW acceleration to work, the sample code assumes that Intel GPU is available and set as primary graphics adapter. The BIOS settings should allow you to select either or both of the GPUs as active. Not sure I can help you beyond that suggestion due to the huge range of BIOSes from different OEMs. You may try to just physically remove the AMD GPU to see what happens.
