I'm not sure if this belongs in user or devel, but here goes.
I'm working with m3u8 files. They can sometimes be live, sometimes VOD.
For live, I need to start the processing from the start. using the command
line I would
ffmpeg --live_start_index 0 -i file.m3u8 [...]
How do I reproduce this in code using the libraries?
I can read VOD just fine, it's only the live ones I can't process.
live_start_index is always -3
I tried
av_opt_set_int(av_format_ctx_->priv_data, "live_start_index", 0, 0)
but it just doesn't work
--------------->
AVFormatContext* av_format_ctx_;
if (avformat_open_input(&av_format_ctx_, filename.c_str(), NULL, NULL)
!= 0)
return false; // Couldn't open file
// Retrieve stream information
if (avformat_find_stream_info(av_format_ctx_, NULL) < 0)
return false;
cout << "Format: " << av_format_ctx_->iformat->name << endl;
if(av_opt_set_int(av_format_ctx_->priv_data, "live_start_index", 0, 0)
!= 0)
cerr << "Couldn't set option" << endl;
av_dump_format(av_format_ctx_, 0, filename.c_str(), 0);
[.,..]

I have looked at the examples, and I also understand ffplay and ffmpeg pass
the parameters using code in cmdutils, but my case isn't parameter based.
Thanks for the help
Louis
