FFmpeg : HLS options cannot be set/get/find
4 septembre 2013, par user2677612We are using
FFmpeg
librariesgit-ee94362 libavformat v55.2.100
.
We are trying to write a simpleHLS
code example based onmuxing.c
standard one.
Let be two input streams, video and audio (they can be synthetic, doesn't matter).
Our purpose is tomux
them intoM3U8
playlist usingHLS
.
Suppose, duration of every TS segment file be 3 sec, and the desirable maximum number of entries inM3U8
output file be 100.From the
FFmpeg
application sources, one can see that the Apple HTTP Live Streaming segmenter implemented inhlsenc.c
file.
And the relevant options there are, as well :"hls_list_size"
,"hls_time"
, etc.
The problem is that we have not succeeded to set/get/find these options in a conventional way, as shown in the following code :// Here is a part of main() program
int64_t i1 = 0;
void *target_obj;
AVFormatContext *ofmt_ctx = NULL;
AVOutputFormat *ofmt = NULL;
avformat_alloc_output_context2(&ofmt_ctx, NULL, NULL, "Example_Out.m3u8");
ofmt = ofmt_ctx->oformat;
// The relevant options ("hls_list_size", "hls_time") are located under ofmt->priv_class->option.
// But AVClass *priv_class is not the first member of the AVOutputFormat.
// So, due to the documentation, av_opt_find...(), av_opt_get...() and av_opt_set...()
// cannot be used for options within AVOutputFormat.
// In practice, any of the following three lines causes exception.
const AVOption *o = av_opt_find2(ofmt, "hls_list_size", NULL, 0, AV_OPT_SEARCH_CHILDREN, &target_obj);
av_opt_get_int(ofmt, "hls_list_size", AV_OPT_SEARCH_CHILDREN, &i1);
av_opt_set_int(ofmt, "hls_list_size", 10, AV_OPT_SEARCH_CHILDREN);
Our question : If there is a way to overcome the problem, i.e. to set/get/find options for
AVOutputFormat
, like forAVCodecContext
(for example) ?Thank you,
Andrey Mochenov.
