  • NVIDIA accelerated ffmpeg (nvenc_h264 ) is dead slow on Amazon G2 instance

    16 novembre 2015, par Abhijit Pathak

    FFMPEG when compiled with following options give abysmal performance on Amazon G2 instance( g2.2xlarge, GRID K520) when compared with standalone Dell-Precision-T1700 (Quadro-k620)

    "--enable-nonfree --enable-gpl --enable-version3 --enable-shared --enable pthreads [b]--enable-nvenc[/b] --enable-runtime-cpudetect --disable-doc --enable-libmp3lame"

    Above ffmpeg binary took 66 seconds to transcode 5.22 mins BVE_Localize.mp4 file with following command.

    time ffmpeg -y -i BVE_Localize.mp4 -strict -2 -vcodec nvenc_h264 -b 5000k -acodec aac -ab 256k -f mpegts BVELocalize.ts ( took 1m6.990s on G2)

    When same ffmpeg command is executed on Dell-Precision-T1700 (Xeon Dual core, Quadro K620) based workstation takes 0m41.572s.

    I would like ffmpeg to perform better on Amazon G2 instance. What do you think I might be missing ? My Amazon G2 instance configuration is Ubuntu 14.04 64 bit, Cuda 7.0 , 352.55 drivers, MSI disabled,NVIDIA SDK 5.0.1

  • Truncate / Trim audio file using start and stop times [duplicate]

    19 juin 2019, par richierich

    This question already has an answer here :

    I am attempting to truncate a .wav file from any length to 1 minute by using the ffmpeg package. once truncated, I want to save the file in another directory.

    I am able to do so with he following command :

    ffmpeg -i ~/test/audio.wav -ss 00:00:00 -t 00:01:00 -async 1 ~/test/test-minute/*.wav

    But my issue is that I would like to be able to iterate through multiple files within my /test directory and truncate each .wav file, then place the new file in the new /test/test-minute directory.

    Also, I would like to keep the same name for each file when it is created in the new directory. Thus, when a copy of audio.wav is truncated to 1 minute, the new file will also be named audio.wav in the other directory.

    In short, how do I perform the truncate process across the entire directory ?
