[FFmpeg-devel] livestream.com us-local news channels

[Georg Stein]

Hello,

this call i do already after  avformat_open_input(&this->avFormatContext,
fileNameChar, fmt, NULL);
i guess my problem is that the above call (and a av_probe_input_format to
the stream url) gives me always "mp3"/"MP2/3 (MPEG audio layer 2/3)" as
format back, ffmpeg and ffprobe returns here "hls,applehttp" what the stream
in fact is

i looked into the source of ffmpeg.c and ffprobe.c but could not figure out
if they set here some AVDictionary options to the callse.

Georg
