Description
Summary of the bug:
FFmpeg will not re-restream an RTP stream to RTSP.
It hangs and must be terminated with Ctrl+C.
After issuing a Ctrl+C, it displays the error: Could not write header for output file #0 (incorrect codec parameters ?): Error number -5 occurred
How to reproduce:

Good question.
The source RTP stream is from a SiliconDust HDHomeRun that is streaming a US TV channel.
I am unable to provide public access to this stream at this time.
I guess it would require a developer to have the equipment.
comment:4 by , 11 years ago
Correct.
FFplay can display the RTP source stream.

For the most part, yes.
It gets messed up when the audio stream changes during commercials.
Besides that, it seems to write OK.

What happens if you try to send the recorded stream via rtsp (either reencoding the stream or with -codec copy)?
comment:8 by , 11 years ago
Does not work either way.

Negative on both, looks like RTSP doesn't work at all.

what rtsp server are you using? I cannot reproduce locally. The following works fine for me:
ffplay -loglevel trace -rtsp_flags listen -timeout 10 -i rtsp://127.0.0.1:12345/live.sdp
ffmpeg -f lavfi -i sine -f rtsp rtsp://127.0.0.1:12345/live.sdp

It works for me on Linux. You are starting the ffplay side first, right?
I will try to test on windows to see if I can reproduce.
comment:22 by , 5 years ago
I thought you had to start streaming with FFmpeg before you could play it back with FFplay?
If I'm fast enough with starting FFplay and then FFmpeg, it does receive content using your commands.
That does not work for my original command though: ffmpeg -f lavfi -i testsrc -f rtsp rtsp://localhost:554/live
My use case was to stream content via RTSP. So FFmpeg would be acting as a server; Running first and then clients connect later.
comment:23 by , 5 years ago
FFmpeg cannot be used as an RTSP server. FFmpeg just sends data to an RTSP server which then re-distributes the content.
VLC has an option to create an RTSP server or could try:
https://github.com/revmischa/rtsp-server
In the example above, ffplay "pretends" it's an RTSP server but plays the content instead of redistributing it, which also explains why you have to start ffplay before ffmpeg
(this option is set with -rtsp_flags listen). Without this option ffplay would behave in the usual way and try to connect to an rtsp server.

Understood.
So the fact that "ffmpeg -f lavfi -i testsrc -f rtsp rtsp://localhost:554/live" hangs is expected?
comment:25 by , 5 years ago
Replying to DJX:
Understood.
So the fact that "ffmpeg -f lavfi -i testsrc -f rtsp rtsp://localhost:554/live" hangs is expected?
For me the command times out and exits straight away if the rtsp server is not up.
Note:
See TracTickets
for help on using tickets.
How can I reproduce this issue?
