Description
Summary of the bug:
Have Zavio D6320 IP camera which sends H265/HEVC via RTSP. Video obtained from the camera cannot be played via ffplay
./ffplay rtsp://user:user@ip_address:554/video.pro1 -rtsp_transport tcp
However at the same time VLC player 2.2.4 (Mac) can play this stream without any problem.
I have saved 5 seconds of H265 stream (640x480 @ 30fps) and attached to this ticket using the following command:
./ffmpeg -v 9 -loglevel 99 -i 'rtsp://user:user@ip_address:554/video.pro1' -rtsp_transport tcp -vcodec copy video640x480.h265
How to reproduce:
% ffplay video640x480.h265 ffmpeg master (snapshot). built on August 3, 2016
You should see only upper right corner of the video is displayed. This problem is reproducible on all resolutions the camera support (320x240, 640x480, 720p, 1080p, 2304x1296).

There are a lot of "Multi-layer HEVC coding is not implemented" records in the log. Maybe that is the issue.

Not sure that this is RTSP issue. ffplay for this camera works perfectly when H.264 stream is coming and video is shown without any issue.

I don't understand, you wrote above "Video obtained from the camera cannot be played via ffplay"

If you make your RTSP service publicly available, I could check the stream data and look for possible bugs in the receiver source code.

Replying to cehoyos:

What I mean is that file video640x480.h265 attached to this issue (it was obtained from this camera) cannot be played via ffplay.

I will contact the owner of the camera and ask for providing a temporary access to the camera.

I cannot make PM here and the owner of the camera does not want his private camera to be accessible online.
So please send me an email and I will provide you a temporary access to this RTSP camera for fixing this bug.
