  • What is the reason for getting libavcodec AVpacket presentation time as 0 ?

    13 août 2019, par Chamara Manoj

    Recently I am using FFmpeg library with VS 2017 decode and encode some video data. I used the example codes given with FFmpeg lib packages, transcoding.c.

    After encoding the video I was trying to extract the frames of the encoded and muxed video.mp4. However, when I read the frames using av_read_frame (AVFormatContext *s, AVPacket *pkt), in the last received frame, pts and dts times are both 0.

    What could be the reason for this ? My Video is playing smoothly and I have used H265 codec.

  • How to find out which audio sample belongs to which frame in a video - with ffmpeg or other tools ?

    30 mars 2021, par tlau5

    I am wondering how I would find out which frame in a video belongs to which audio sample.

    


    Lets say : I know audio sample 39822 has the characteristic I am looking for. Using the information contained in the container, I want to find out to which frame the audio sample was recorded. (Key frames/ Samples ?)

    


    I was thinking ffmpeg could help me with this problem.

    


    I tried to find the answer within the ffmpeg documentation but did not succeed.

    


    Maybe you guys can give me a hint which tool (maybe even other than ffmpeg) to use or where to look specific.

    


    Thanks in advance
Tim

    


  • Proxy a rtmp stream

    22 février 2015, par lsborg

    How could I proxy a rtmp stream ?

    I have two raspberry pi streaming live video from raspicams on my LAN. Each raspberry pi sends the video to ffmpeg which wraps in flv and sends to crtmpserver.

    A third server using nginx, has a static html page with two instances of jwplayer, each pointing to one raspberry pi.

    The setup is just like this one.

    The web server uses authentication and I’d like streams not to be public too.

    I’m thinking of trying nginx-rtmp-module, but I am not sure if it would help me. Also, it seems dormant and has many open issues.

    I’m open to suggestions, thanks in advance !
