</listviewitem>I really do not understand in the slightest what is causing all these errors, and why the video file won’t play ?
If anyone is able to help I will highly highly appreciate it !I am using Genymotion Emulator - Google Nexus 4 - API 21
Thank you very much !

Unmapping memory-mapped images that are created during processing
23 avril 2013, par user2309283I have a pretty big issue, although I only have the symptoms, and a theory on the cause.
I have a C++ application under Windows 7x64 that uses system calls to FFMPEG 0.7.13 to extract frames from videos. When running, the parent application maintains a nice, predicable memory footprint in memory profilers (task manager, RAMMap) of about 2MB. I can see the individual calls to FFMPEG also come and go without incident. The trouble is, after about 100 calls to FFMPEG, and 70,000+ PNGs created (no one directory has more than 1500 pngs), the Windows memory page size raises gradually from about 2.5GB to over 7.0GB, and the system is brought to its knees. The sum of the processes for all users is no where near the reported Memory Page amount.
I thought it might be Windows Search indexing related, so I turned off the indexing for the output directories in question using SetFileAttributes() and FILE_ATTRIBUTE_NOT_CONTENT_INDEXED, and while it seems to be working as advertised, it does not seem to combat the issue at hand. My current running theory is that all of these extracted PNGs are either fully or partially memory mapped, by FFMPEG or something else. I can also see the output PNGs under the RAMMap Physical Pages tab as standby mapped files.
Question :
Is there enough information here to possibly diagnose the exact problem ?
Do I have a way to combat this issue ?Thanks in advance...

Instead, I'd like to use ffmpeg to capture from specifically that child window.
Ideas ? Tips ? Maybe some other hacks to accomplish this ? Thanks :)
