  • Video won't play on iphone

    18 octobre 2016, par Merc

    I have an app that places videos online, and cannot find a way to get iPhones to actually play them.

    The video is here

    The file was created using ffmpeg from within the app.

    Is this a codec problem ? What shall I do to make sure iPhones can actually play them ?

  • Close and reopen stream

    7 janvier 2020, par Expressingx

    I’m streaming video from a camera into a file. Using mp4 but if there is unexpected power off the video gets corrupted. So I’m going to store the video in a backup file where ffmpeg will write frames to temporary file and in some interval the content of that file will be copied to the backup file. So far so good, but in order backup file to be not corrupted I have to write the trailer first (I guess) to the temp file and eventually close the stream and then copy the content. After that reopen the stream to the temp file. But I’m getting Attempted to read or write protected memory if I try to call av_write_trailer() after its already called once.

    Is there even a way to achieve that or if I expect power off I should use other format like flv ?

  • PSNR for YUV files using matlab [duplicate]

    29 février 2016, par apiproj

    This question already has an answer here :

    In my video streaming application I have two yuv files.One is original which is am streaming over the network after x264 encoding, another is reconstructed decoded yuv file in receiver side.

    How to calculate PSNR value between two YUV files in MATLAB or ldecoder or using any other tool ?

    Thanks in advance.
