  • nal_ref_idc value for the last frame in GOP when B frame is there for x264 encoding

    21 février 2018, par MSD Paul

    nal_ref_idc value during x264 encoding for each frame signifies that whether decoder has to remember or keep those frames in memory or not or in other words, whether those are reference pictures or not.

    In general, I frame with nal_ref_idc value =3 and for P frames, the value = 2.

    If one considers the GOP of this pattern, IPPPIPPP......

    then why the last P also has a nonzero value of 2. I think it should be 0.

    can anyone please tell why the last frame has nonzero nal value ?

  • Improve FFmpeg time ? conversion takes very long

    15 avril 2015, par Rubytastic

    I have several rules to convert a movie to several formats and create a preview image. Problem is the execution of these takes very long.
    Also the outputted quality is very low. I harvested these examples from several sources.

    What could be done to
    * improve speed
    * improve quality ?

     ffmpeg -y -i /file/$1.flv -acodec libmp3lame -ar 44100 -ac 1 -vcodec libx264 /file/$1.mp4
    
 ffmpeg -i /file/$1.mp4 -acodec libvorbis -aq 5 -ac 2 -qmax 25 -threads 2 /file/$1.webm
