Can't play RTSP stream on a specific device.
I discovered a bug when trying to play a rtsp stream from a camera. Although on other devices it's working ok, specifically on this device it doesn't work. It seems this is the error:
"RTP subsession 'video/H264' failed (getsockname() error: Bad file number)"
Also these are the logs: vlc_logcat_20190727_091526.log
If you need more information ,i can help with debugging.

added VLC core label
Can you share the logs where it does work?
Edited by Jean-Baptiste Kempfadded Needs more info label
Sure, here are the logs from a Xiaomi Redmi Note 6 Pro (Android 9, ARM64) vlc_good_log.txt
That error is missing in this case.
I can reproduce the same error message with 2.5.17, 2.9.0, 3.0.13, 3.1.0, 3.1.5, 3.1.7 and 3.2.2 on an old Asus TF700t Android 7.1.2 (custom ROM KatKiss Nougatella #39 (closed)). It used to work with 3.0.13 on the same hardware with an older version of KatKiss so some system changes must have broken it.
Building current master reveals additional messages:

Unable to determine our source address: This computer has an invalid IP address: 0.0.0.0right before theRTP subsession 'video/H264' failed (getsockname() error: Bad file descriptor)Apparently, that's a recurring issue with the live555 library:
I've been trying to add traces into the code of
GroupsockHelper.cppto better understand what's going on, the code properly compiles and the lib is built, but my modifications are not taken into account, the resulting APK does not seem to embed the proper libs
Also, I've noted the changelog for more recent versions of of the live555 lib mentions a lot of fixes but this one in particular grabbed my attention:
2019.05.03:
- Made it possible to specify = at compile time - that you don't want to use the multicast loopback trick for finding your system's IP address. To disable this mechanism, compile "groupsock/GroupsockHelper.cpp" with "-DDISABLE_LOOPBACK_IP_ADDRESS_CHECK=1".
see http://live555.com/liveMedia/public/changelog.txt
Upgrading live555 does not seem an option but maybe the change can be backported as a patch.
Still digging...
This could be related to this ticket. Also over the VLC trac (with possible solution in the comments).
