  • Writing multithreaded video and audio packets with FFmpeg

    27 février 2017, par Robert Jones

    I couldn’t find any information on the way av_interleaved_write_frame deals with video and audio packets.

    I have multiple audio and video packets coming from 2 threads. Each thread calls a write_video_frame or write_audio_frame, locks a mutex, initialize an AVPacket and writes data to an .avi file.

    Initialization of AVCodecContext and AVFOrmatContext is ok.

    — Edit 1 —

    Audio and video are coming from an external source (microphone and camera) and are captured as raw data without any compression (even for video).
    I use h264 to encode video and no compression for Audio (PCM).

    Audio captured is : 16bits, 44100khz, stereo

    Video captured is 25FPS

    Question :

    1) Is it a problem if I write multiple video packets at once (let’s say 25 packets/sec) and just one audio packet/sec.

    Answer : Apparently not, the function av_interleaved_write_frame should be able to manage that kind of data as soon as pts and dts is well managed

    This means I call av_interleaved_write_frame 25 times for video writing and just 1 for audio writing per second. Could this be a problem ? If it is how can I deal with this scenario ?

    2) How can I manage pts and dts in this case ? It seems to be a problem in my application since I cannot correctly render the .avi file. Can I use real time stamps for both video and audio ?

    Answer : The best thing to do here is to use the timestamp given when capturing audio / video as pts and dts for this kind of application. So these are not exactly real time stamps (from wall clock) but media capture timestamps.

    Thank you for your precious advices.

  • laravel 5.5 not compatible with new ffmpeg

    29 mars 2018, par Stephany. S123

    I need to download ffmpeg for my laravel application. I found a package but its only compataible with laravel 5.6 but the thing is I can not use use 5.6 because it requires php 7.1 and up and I have laravel 5.5 which supports php 7.0 and up and my web hosting site has up to php 7.0 so I have to keep my laravel version at 5.5. So where is the ffmpeg version for laravel 5.5. I hope you understand where I am coming from. Thanks in advance
