  • Unmapping memory-mapped images that are created during processing

    23 avril 2013, par user2309283

    I 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...

  • H264 Encoders other than ffmpeg x264

    5 septembre 2016, par 0pcl

    The iPhone app I am working on captures images in series within certain user-defined time interval, I am looking for a way to combine these images into H264 encoded videos. I have done some research on Google, it looks like I will have to use something like ffmpeg/mencoder on iPhone ? (Also found someone ported ffmpeg to iPhone, ffmpeg4iPhone)

    However, I found that x264 is under GPL license, and requires me to open source my project if I use ffmpeg. Also found some people suggested to use Ogg Theora, but I will need to port it to iPhone if I use it. (Which I am not sure how to do it now).

    Is there any workaround for this ? Any ideas ? Thanks.
