  • FFMPEG command runs forever even on using timelimit

    21 décembre 2017, par t6nand

    Mostly I use a java code to run FFMPEG bash commands for watermarking a logo on video. I am using the following FFmpeg command to overlay an image on video. I have observed that at times for some random videos, the process keeps on running even after the timelimit assigned to it expires. At times it’s more than a day or couple of days until not directly killed using kill -9 pid :

    ffmpeg -timelimit 900 -y -i
    input_video
    -i logoImage -filter_complex "[0:v]scale=trunc(iw/2)*2:trunc(ih/2)*2[even] ;[1:v][even]scale2ref=iw*0.25 :(iw*0.25)*(0.46446702)[2nd][ref] ;[ref][2nd]overlay=(main_w-overlay_w) :(main_h-overlay_h)"
    -c:v libx264 -b:v 300K -crf 28 -preset slow outputVideo

    But this command never completes even on using -timelimit flag at times for some videos.

    I have observed that for such processes output from ps aux|grep ffmpeg yeilds in something like :

    ubuntu 16620 0.6 6.7 1595044 515392 ? Sl Dec20 12:05
    ffmpeg -timelimit 900 -y -i
    input_video
    -i logoImage -filter_complex "[0:v]scale=trunc(iw/2)*2:trunc(ih/2)*2[even] ;[1:v][even]scale2ref=iw*0.25 :(iw*0.25)*(0.46446702)[2nd][ref] ;[ref][2nd]overlay=(main_w-overlay_w) :(main_h-overlay_h)"
    -c:v libx264 -b:v 300K -crf 28 -preset slow outputVideo

    It indicates that this process is in interruptible sleep state i.e. waiting for an event to complete. On using sudo strace -p 16620 to trace which system call is this process hung up on it results in something like :

    Process 16620 attached write(2, "frame= 4121 fps= 10 q=33.0 size="...,
    99

    i.e. it’s stuck writing to a file.

    What could be the reason for this problem ?
    And is there any other way to kill FFMPEG process which overshoots desired time limit ?

  • How to fix scrambled output

    26 janvier 2020, par Krishnakumar

    I am seeing the following scrambled output for a live stream when processing an udp input stream. I am using the recently downloaded ffmpeg from GIT. Stop and Start of ffmpeg command resolves the issues temporarily.
