#1185 new defect

broken playback of rtsp streams - under windows at least

Version: git-master Keywords: rtsp udp

Description

This refers to or is the same bug as https://ffmpeg.org/trac/ffmpeg/ticket/651

I am not able to properly decode any udp rtsp stream under windows with ffmpeg.
It says "RTP: missed n packets" all the time and the display is corrupt.

For some sources I was able to avoid the bug by switching to TCP transport (rtsp_transport=tcp) but unfortunately that is not possible on many of them.

Tested various sources like a vlc-player generated stream, some internet sources and streams from several lan cameras.

Verified that bug with windows versions of ffplay (downloaded from http://ffmpeg.zeranoe.com/builds/, ffmpeg (less errors but they still exist) and my own implemantation of an ffmpeg based player compiled from the current source. 32 bit and 64 bit versions.

I presume there is something wrong with the udp-rtsp protocol implementation in ffmpeg. Some problem with the ring buffer there or different buffer sizes under windows - dont know.
Unfortunately I was not able to test a unix build yet.

The fact that I get less errors with ffmpeg but with ffplay lets me believe that there is some connection to the frequency network read functions are called.

This is the output from ffmpeg trying to decode the stream gAmeOver supplied in his bug report:

I get all the same errors "RTP: missed n packets" (not always only 1 like in this case) with any rtsp stream I tried, also local ones.

Sorry posted the wrong output about one of my local streams.
Here is the right one with an internet stream, so you can reproduce:

  • Priority changed from important to normal

Do you think this is a regression?

Replying to cehoyos:

Do you think this is a regression?

Can not say that.
You can read quite a bit about similar problems here.
And some say there was something fixed.
All I can say: For me it never worked - but I am only trying since three months or so.

Also tried with libav - same results.
All streams play fine with VLC Player.
