  • is Cloud API's needed for Video Conversion to save huge time ?

    7 juillet 2017, par user2224250

    I have seen a couple of ffmpeg software’s which converts a video x format (1.8 GB) to y format (1.8 GB) in less than 90 seconds

    For example IDealshare VideoGo

    When I work with ffmpeg in the terminal, these sort of conversions takes atleast one hour. Moreover, when I compare to the above software, am facing a very very big number interms of time.

    May be, do you think for these fast conversions, we must take help from third party cloud API’s (software’s) such as amazon elastic transcoder etc etc.

    Any pointers would be really appreciable !!

  • Libav AVFrame to Opencv Mat to AVPacket conversion

    14 mars 2018, par Davood Falahati

    I am new to libav and I am writing a video manipulation software which uses opencv as its heart. What I did is briefly as below :

    1- read the video packet

    2- decode the packet into AVFrame

    3- convert
    the AVFrame to CV Mat

    4- manipulate the Mat

    5- convert the CV Mat
    into AVFrame

    6- encode the AVFrame into AVPacket

    7- write the packet

    8- goto 1

    I read dranger tutorial in http://dranger.com/ffmpeg/tutorial01.html and I also used decoding_encoding example. I can read the video, extract video frames and convert them to CV Mat. My problem starts from converting from cv Mat to AVFrame and encode it to AVPacket.

    Would you please help me with this ?

  • ffmpeg conversion .dav to any video files
