    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Why can't I seek using PTS while reading an MXF file until av_write_trailer() is called ?

    1er mai, par Summit

    I'm writing an MXF file using FFmpeg in C++ and then reading it back for real-time playback. However, I'm running into a problem : seeking by PTS (av_seek_frame()) doesn't work properly until I call av_write_trailer() at the end of the writing session.

    


    Here’s the workflow :

    


    I'm encoding and writing frames to an MXF file using avformat_write_header() and av_interleaved_write_frame().

    


    I want to read from the same file while it’s still being written (like a growing file or EVS-style live playback).

    


    But seeking using av_seek_frame() to a specific PTS fails or behaves incorrectly until I finalize the file with av_write_trailer().

    


    Here is a simplified version of my writing logic :

    


    avformat_write_header(formatContext, nullptr);
// ... loop ...
avcodec_send_frame(codecContext, frame);
avcodec_receive_packet(codecContext, &pkt);
av_interleaved_write_frame(formatContext, &pkt);
// NO call to av_write_trailer() yet


    


    And this is how I try to seek in the reading logic :

    


    av_seek_frame(inputFormatContext, videoStreamIndex, targetPts, AVSEEK_FLAG_BACKWARD);
