  • why I can't compile x264 or ffmpeg downloaded from git [closed]

    4 avril 2013, par Monjura Rumi

    It has been just a few days that I am using x264, ffmpeg and trying to take help from codes in git. I am always having some peculiar problem. It seems like no one or few people faced such problems. Here is one of those problems. If I download x264 or ffmpeg using git then I could not compile that source code. At first terminal will show ./configure: Permission denied. Then If I change permission of configure file using chmod 755 command then it will show ./configure: /bin/bash^M: bad interpreter: No such file or directory. To build x264 and ffmpeg I have followed this link https://github.com/lince/libffmpeg-c/wiki. My attempt to compile x264 has failed. Can you please tell me how can one use source code downloaded from git ?

    How to speed up, adjust color, Crop, Scale and Mix two audio inputs into a video by FFMpeg ?
When run not show result

    


    I try to change some function in filter_complex but not work or show result when run.
My goal want mix one audio to one video and apply some filter like hflip, crop, scale, speed up and adjust color for video.

    


    My command :

    


    ffmpeg -y -i "%%a" -i "sound\123.mp3" -c:v copy -filter_complex "[0:v]hflip,crop=720:720,scale=1080 :-1,eq=saturation=1.3,eq=brightness=0.06:saturation=2,setpts=0.8*PTS[v] ;[0:a]atempo=(1/0.8)[a],[0:a][1:a] amix=inputs=2:duration=longest [audio_out]" -map "[v]" -map "[a]" -c:v -map 0:v -map "[audio_out]" h264_nvenc "output%% na.mp4

    


  • Make ffplay leave video on GPU

    6 février 2019, par tmlen

    Is there a way to use ffplay to decode a video on GPU (using the h264_cuvid decoder, for example), and then show the output onscreen, without copying each frame to the host first ?

    I’m using the following command to launch ffplay decoding+playing a sequence of h264 files on the GPU through CUVID :

    ffplay -v 64 -loop 0 -vcodec h264_cuvid video.mkv

    It plays the video properly, but if I run the NVidia Profiler (nvpp), the timeline looks like this :

    NVPP timeline

    It seems that it does the decoding on the GPU, but then copies the output to host memory (Memcpy DtoH) for each frame.

    Is it possible to have ffplay skip this step, and instead directly show the image on GPU using its graphics context ?
