  • Overlaying alpha images on a video using ffmpeg

    10 mai 2016, par neuro_sys

    I have the following ffmpeg-cli command which does not produce the described effect in documentation. Could this be a bug, or I have something wrong with the command.

    ffmpeg \
    
    -y \
    
    -i small.mp4 \
    
    -i monkey/monkey_%04d.png \
    
    -filter_complex "[0:v][1:v]overlay=enable='between(t,1,5)'[out1]" \
    
    -map '[out1]' \
    
    output.mp4

    I expect it to overlay the #1 stream on top of #0 between seconds 1 and 5.

    You may download the test tarball from this link :

    It includes assets for the test case.

    The build I tried with :

    • ffmpeg-3.0.2-64bit-static (available online)

  • high memory & cpu usage in ffmpeg C sample when muxing audio and video

    24 juin 2016, par chandu

    I am using the muxing.c example provided with ffmpeg 3.0 version to create an MP4 file (H.264 & AAC) with VS 2013.

    The sample is working fine with default width & height for video, but when I changed the width to 1920 and height to 1080, the sample is taking nearly 400MB & 60-70% cpu usage (using task manager & in Release mode) throughout the program. I have used multi threading also.

    I tried to free the encoded packet after calling write_frame(), but to no success.
    The memory is being released only after calling avcodec_close().

    Could anybody please tell me what I am doing wrong ?

    I am adding link (https://drive.google.com/open?id=0B75_-V7se7tmWUhyM0ItS0kzUVk) to code I tested with VS 2013.

    The screenshot link https://drive.google.com/open?id=0B75_-V7se7tmVm4tUjFtSnNNSHc

    The STREAM_DURATION value in the sample is set to 120 seconds (even tested with 600 seconds) and I changed default Height & Width values of AVCodecContext in add_stream function for video type to 1080 & 1920 respectively. Through out program, it is taking 355 MB, not changing at all. I think, once frame is encoded using avcodec_encode_video2 and written to the file, the memory should be released.

    Please correct me if I am wrong.
