  • Convert images into video

    24 septembre 2017, par Disha Shukla

    I have some images in the folder. I want to convert all images into videos. But the problem is that when the resolution is different it shows the error. I don’t want to stretch the images in the video. I just want to keep image size as it is. But it shows this error.

    My Command :

    ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 -shortest -c:v libx264 -r 30 -vf "scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):ow/(16/9):(ow-iw)/2:(oh-ih)/2" -aspect 16:9 -pix_fmt yuv420p out.mp4 -y

  • Using ffmpeg for stream encryption by srtp in windows

    11 avril 2015, par user3248865

    I have been trying to make encrypted stream via ffmpeg and I´ve found srtp support in this library (ffmpeg documentation). Unfortunately, it seems that encryption doesn´t work at all. I´m using the following command to send stream :

    ffmpeg -re -i "output.mpg" -vcodec libx264 -f flv "srtp://192.168.0.100:7777?srtp_out_suite=AES_CM_128_HMAC_SHA1_80&srtp_out_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

    and this one for stream receiving :

    ffplay "srtp://192.168.0.100:7777?srtp_in_suite=AES_CM_128_HMAC_SHA1_80&srtp_in_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

    They work good.
    But, If I change the command for ffplay to this one :

    ffplay udp://192.168.0.100:7777

    it works too and I can watch the video. So, it means that encryption for srtp doesn´t work ?

    1. Is the stream encryption by using ffmpeg possible (not only srtp) ?
    2. If so, What am I doing wrong ?

    Thanks in advance.
