[Live-devel] Broken data when streaming HEVC video

[Roland Aigner]

By the way: I'm using the most recent VLC version 2.2.4 and the 11-28-2016 live555 build of testProgs -- according to the changelog of the latest version, there have been no code changes in related matters, so I think it's safe to say I'm up to date.

Best,
Roland

I put it on my Dropbox [1], you should be able to download it from there. 

"checker.265" is a short video of a checker pattern moving in diagonal, this is the input video, streamed via live555MediaServer. See the screenshot "checker (MPC replay).png", it looks fine when replayed from disk. When I connect via VLC using the URL rtsp://<my-ip>/checker.265, I can see corrupted output (see screenshot "live555MediaServer to VLC.png"). When I use openRTSP, it generates the file "video-H265-1", which, when replayed is also corrupt (see screenshot "live555MediaServer to openRTSP (MPC replay).png"). 

Best,
Roland

> In order to eliminate sources of error, I tried to reproduce this with as little of my own code as possible. For that I write a file with 6176x2076 HEVC encoded data to disk and doublecheck with ffplay -- the file seems to be fine. I use live555MediaServer.exe as an RTSP server and VLC as a client -> the video displayed by VLC is broken. I also tried to capture the received data and write it to disk via openRTSP. The produced file is also broken

Please put an example “.h265” file - that illustrates this problem - on a (publicly-accessible) web server, and send me the URL, so I can download and test this myself.
