[FFmpeg-user] ffprobe with mpegts/udp

[Andriy Gelman]

Hello,

I have a question about using ffprobe with mpegts/udp.

Consider the following example:

*$ echo "test" > testfile.dat  #create test file*
*$ ffmpeg -f bin -i testfile.dat -c copy -f mpegts output.ts*

Running ffprobe on output.ts outputs the stream format

*$ ffprobe output.ts  *







*Input #0, mpegts, from 'output.ts':  Duration: N/A, start: 1.400000,
bitrate: N/A  Program 1     Metadata:      service_name    : Service01
service_provider: FFmpeg    Stream #0:0[0x100]: Data: bin_data
([6][0][0][0] / 0x0006)*

However, when I use udp, i.e.
*$ ffmpeg -f bin -i testfile.dat -c copy -f mpegts udp://127.0.0.1:6500
<http://127.0.0.1:6500>*

ffprobe just hangs and doesn't output any results:
*$ ffprobe -f mpegts udp://127.0.0.1:6500 <http://127.0.0.1:6500>*

Do I need to set some additional parameters, like probesize or analyze
duration here?

Your help is much appreciated!
Thank you,
Andriy

P.S. I am on the origin/master branch of ffmpeg
