I mentioned this problem on the ffmpeg developpers mailing-list. I sent a sample video. This is what I was told:
The first 37 bytes look similar to a video stream but are invalid for a hevc video, making auto-detection more difficult. Not sure if this should be fixed, could you tell us the name of the IP camera? Could this be a bug in openrtsp?

You must name the file with the extension .h265. With the right extension, the conversion with ffmpeg works perfectly ! ________________________________________ De : live-devel [live-devel-boun...@us.live555.com] de la part de Nicolas Julien [nicolas.jul...@cdvi.com] Date d'envoi : lundi 21 septembre 2020 11:06 À : LIVE555 Streaming Media - development & use Objet : Re: [Live-devel] Record a H265 stream from IP camera to file Hi, I tested the command lines. openrtsp generates the raw files as expected : Started playing session Receiving streamed data... Outputting data from the "video/H265" subsession to "video-H265-2-00010-00020" Outputting data from the "video/H265" subsession to "video-H265-3-00020-00030" Outputting data from the "video/H265" subsession to "video-H265-4-00030-00040" etc... Unfortunately the conversion with ffmpeg does not work because the program detects a lot of errors : [h264 @ 03965300] no frame! [h264 @ 03965300] missing picture in access unit with size 4840 [h264 @ 03965300] data partitioning is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. [h264 @ 03965300] If you want to help, upload a sample of this file to https://streams.videolan.org/upload/ and contact the ffmpeg-devel mailing list.

Specifically, our implementation of outputting “.mp4”-format files does not yet handle writing “.mp4”-format files that contain H.265 video. (See the “if” statement in “liveMedia/QuickTimeFileSink.cpp”, starting at line 644.) One way you can overcome this problem is to instead record a raw H.265 video file, *not* a “.mp4”-format file. I.e. run: openrtsp -b 200000 -u admin admin -v -d 10 -w 2560 -h 1440 -f 15 rtsp://192.168.1.64:554/Streaming/Tracks/101?transportmode=unicast&replaymode=onvifreplay i.e., without the “-4” option, and without stdout redirection. This will give you a video file, named something like “VIDEO-1-H265”, which you can rename as “test.h264” (note, with a “.h264” filename suffix, even though the data is H.265). Then use “ffmpeg” to convert this to a “.mp4”-format file, e.g. ffmpeg -i test.h264 -c copy test.mp4 Ross Finlayson Live Networks, Inc. http://www.live555.com/ _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
