  • 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.

  • FFMPeg stuck while processing a video

    15 juin 2017, par Muhammad Umar

    I am trying to add slow motion to an FFMPEG video in android

    On my terminal original query i use is

    ffmpeg -i soon.mp4 -filter_complex "[0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a]" -map "[v]" -map "[a]" output.mp4

    Here is my code in android,

        String cmd = "/data/data/PACKAGE_NAME/files/ffmpeg -i "+ videoFileName +" -filter_complex [0:v]setpts=0.5*PTS[v];[0:a]atempo=2.0[a] -map [v] -map [a] " + file.getAbsolutePath();

    In Android , i have only removed quotation marks since ffmpeg is not recognising these.

    When i exceute FFMPEG,
    following happens

    After that nothing happens, FFMPEG seems like stuck in oblivion. Any ideas what could be wrong
