  • FFmpeg - Initiating codec parameters manually

    5 février 2021, par Artur Pasymowski

    My application uses FFmpeg to demux and decode video streams from IP cameras. Video is encoded with either H.264, H.265, or MJPEG. Formats used include RTSP, and MPEG-PS. Currently I am using avformat_find_stream_info function to init format context when opening stream, and it works OK, but it introduces some delay at the beginning. I was able to reduce it by changing probe size, but I can't make it less than 2 seconds without making it unreliable. I would like to get rid of this delay.

    


    I can get stream information from camera before opening it, so I wanted to initialize stream information in AVFormatContext without probing it. Is it possible with FFmpeg API ?

    


  • Evolution #4105 : Constante ou config ?

    28 février 2018, par b b

    b_b attention, dans l’idée de Maieul la constante est inversement prioritaire, et non pas à chercher en dernier recours.

    Toi tu n’as pas lu mon message après la correction que j’y ai apporté ;)

    Mais mon avis c’est que les deux sont un peu de la merde. :D

    Un plaisir :)

  • Laravel FFMPEG, converting large video on smaller EC2 instances

    30 août 2019, par Jeremy Layson

    I’m using ffmpeg on a laravel project (uploaded on AWS Elastic Beanstalk using t3.micro for now). My problem is that my budget can only go for t3.small but sometimes, I’ll have to process large video files like 2GB or even 5GB.

    My current set-up can process smaller files like 30MB and convert them to M3U8 (HLS) so there’s no problem with the set-up. The problem arises when I’m trying to upload and convert a 2GB file as my EC2 instance only has 1GiB of memory.

    Is there a way for FFMPEG (pbmedia/laravel-ffmpeg) to "chunk" the conversion so that it uses less memory ? Doesn’t matter if it takes double the time to convert.
