  • Rescaling and slowing down a movie at the same time with ffmpeg

    21 décembre 2016, par ejl62

    I would like with ffmpeg to slow down a movie I am creating using the flag :

    -filter:v "setpts=2.0*PTS"

    However the height of my still images is not divisible by 2, so to avoid the error : height not divisible by 2 (1238x833), I am using the flag :

    -vf scale="trunc(iw/2)*2:trunc(ih/2)*2"

    (I also tried -vf scale=1238:-2).

    When I do this the film is generated but it isn’t slowed down, like if the -filter:v "setpts=2.0*PTS" wasn’t there.

    Is there something particular to do in order to have both option working at the same time ?

    Here is the complete command I am using :

    ffmpeg -an -i ./movie/cphmd1.%05d.ppm -vcodec libx264 -pix_fmt yuv420p -b:v 5000k -r 24 -crf 18 -filter:v "setpts=2.0*PTS" -vf scale="trunc(iw/2)*2:trunc(ih/2)*2" -preset slow -f mp4 cphmd1_slower.mp4

    Many thanks in advance !

  • FFmpeg : real-time buffer[ ] [input] too full or near too full (101% of size : 3041280 [rtbufsize parameter]) frame dropped

    5 janvier 2017, par lostin2010

    I use the library of ffmpeg to decode stream from [TTQ HD Camera] and encode it to a rtmp stream.
    but I receive a lot of warnings like the picture below.
    i try to set qmin and qmax , it seems a little better. but still not totally resolve the problem.

    encoder_context->qmin = 10;
    
encoder_context->qmax = 51;

    who knows this is why ?

    doc : clarify option on looping infinitely in movie filter

    Clarify that setting loop=0 is required to make the stream loop infinitely, rather than saying that a value "less than 1" is needed.
