Re: [Libav-user] avformat_find_stream_info times out on rtp stream

2016-09-17 Thread Charles 

Is it also reproducible with "./ffmpeg -i rtp://hostname:port"?

Carl Eugen


Think there is an issue
Version 2.6.8 from linuxtech repo is working
Version 3.1.3 from ffmpeg is not

Not exactly sure but here is my test case.
Create rtp stream with ffmpeg 3.1.3
Tried to ffprobe stream with ffmpeg 3.1.3 and 2.6.8

Results
https://gist.github.com/LinuxwitChdoCtOr/3099b6e68bd5597776e33f3a56c74251

I can also view the stream with VLC using old ffmpeg_libs

Thanks

Re: [Libav-user] avformat_find_stream_info times out on rtp stream

2016-09-17 Thread Charles 


Is this timeout a known bug?


Is there an rtp issue?


Is the issue reproducible with current FFmpeg git head?


Dunno, in ofline lab, will try tomorrow



Is it also reproducible with "./ffmpeg -i rtp://hostname:port"?
Is it also reproducible if you build with "./configure && make"?
