  • When a ffmpeg runs, I can't connect to ftp

    24 mars 2019, par Jintor

    When a ffmpeg is running in the server, it takes CPU and load average is going up. but as long as the ffmpeg runs, I cannot access ftp with normal users :(

    I still can connect as root, but I always have to wait for ffmpeg to finish to connect.

    I tried to edit pure-ftpd.conf MaxLoad

    MaxLoad 11

    but it seem to affect

    # If the system load is greater than the given value, anonymous users
    
# aren't allowed to download.

    still have to wait for ffmpeg to finish.

    Is there a way ti fix this ?

  • Drop late RTMP AVPackets - FFmpeg

    25 novembre 2014, par Mihai Ghete

    I’m using FFmpeg to read RTMP streams in an iOS application. It is basically a Player for RTMP streams. The problem is that when the network is to busy, av_read_frame takes too much time. In conclusion, the latency increases over time. Are there some FFmpeg setups that I can use so that it will drop late frames or make av_read_frame return if it was unable to read the packet in a defined period of time ?

    Any suggestion would be helpful. Thank you in advance.

  • Fast Video Compression on Android

    7 avril 2017, par leap of faith

    I want to upload video files to server and compress before uploading. I’m using ffmpeg libx264. I have seen viber can upload 30 second video file of size 78MB within a minute [reduce it’s down to 2.3MB]. I want to know how do they do it so fast ?

    What I have tried so far -

    FFMPEG version :  n2.4.2 
    
Built with gcc 4.8
    

    
Build Configuraiton : --target-os=linux --cross-prefix=/home/sb/Source-Code/ffmpeg-android/toolchain-android/bin/arm-linux-androideabi- --arch=arm --cpu=cortex-a8 --enable-runtime-cpudetect --sysroot=/home/sb/Source-Code/ffmpeg-android/toolchain-android/sysroot --enable-pic --enable-libx264 --enable-libass --enable-libfreetype --enable-libfribidi --enable-fontconfig --enable-pthreads --disable-debug --disable-ffserver --enable-version3 --enable-hardcoded-tables --disable-ffplay --disable-ffprobe --enable-gpl --enable-yasm --disable-doc --disable-shared --enable-static --pkg-config=/home/sb/Source-Code/ffmpeg-android/ffmpeg-pkg-config --prefix=/home/sb/Source-Code/ffmpeg-android/build/armeabi-v7a-neon --extra-cflags='-I/home/sb/Source-Code/ffmpeg-android/toolchain-android/include -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -fno-strict-overflow -fstack-protector-all -mfpu=neon' --extra-ldflags='-L/home/sb/Source-Code/ffmpeg-android/toolchain-android/lib -Wl,-z,relro -Wl,-z,now -pie' --extra-libs='-lpng -lexpat -lm' --extra-cxxflags=

    Command :

    ffmpeg -y -i /storage/emulated/0/main.mp4 -s 480x320 -r 20 -c:v libx264 -preset ultrafast -c:a copy -me_method zero -tune fastdecode -tune zerolatency -strict -2 -b:v 1000k -pix_fmt yuv420p /storage/emulated/0/output.mp4

    The result so far is, a 30second 78MB file gets compressed to 4.3MB which takes around 1min 28seconds. Here is the console dump - http://pastebin.com/rn81acGx . I mainly want to reduce the time it takes to compress. How can I achieve this ?

    Thanks in advance.
