  • How to compare visually two look alike videos of different codec, size, resolution

    18 novembre 2015, par Abdul Gafoor

    Is it possible to compare pragmatically, two look alike videos of different codec, size and resolution. I went through the some tools like ffmpeg opencv.

    Or in the another context, Lets an image should be compared with video and find out the exact time where the image visually present in the given video. The codecs, size and resolution of video and image may vary.

  • FFMPEG - convert video without losing resolution

    29 octobre 2015, par Srh

    I am using ffmpeg to convert mp4 video from youtube. The video is HD 1080. When I convert it to mpeg2video, the video loses its sharpness, regardless of the -s 1920x1080 parameter. How can I convert the video without losing picture sharpness ? The command I use is :

    ffmpeg -i BBB.mp4 -vcodec mpeg2video -s1920x1080 -acodec copy -f mpegts BBB.ts

  • FFMPEG gets stuck on higher resolution or frame rate [H265]

    29 octobre 2015, par Anakooter

    I am running the following command which works perfectly on my system running Elementary OS on Intel Corei5 :

    ffmpeg -f v4l2 -i /dev/video0 -c:v libx265 -x265-params crf=14:vbv-maxrate=128:vbv-bufsize=32:keyint=10:qcomp=0.5:rd=5:ctu=64:min-cu-size=8:cu-lossless=false:fast-intra=false:strong-intra-smoothing=false -tune zerolatency -s 640x480 -preset ultrafast -r 5 -pix_fmt yuv420p -an -strict experimental -f mpegts udp://239.0.0.1:5002

    but if I change the output size to 800x600 and or increase the frame rate from 5 to 10. After a few seconds the video gets stuck.

    I have monitored the CPU usage for both the commands and it is almost identical that is between 300 to 400 percent ( since 4 cores ).

    Any possible answers to mitigate the issue.
