Not compatiable with SRT < 1.3.0 (Support HSv4) #146
Comments
vlc.mp4Can't seem to repro on Could this be an issue with the srt version that VLC is finding? I'm using VLC on arch, and I notice ti's an optional dep so I assume it's using my system version which is 1.4.4. |
|
Well looking at my video there is a whole slew of "packet dropped" messages but idk if these are because it's not valid video data or not... |
|
If you're interested, it would be great to have an example that actually streams a .ts file--we already have ac-ffmpeg as an optional dependency for examples, I'll code one up sometime or you could, it should be relatively straightforward |
|
Ok, works fine for a real video for me:

srt-vlc-480p.movhere is my fork:

I think VLC must bundle an ancient SRT version. it seems that you're on macOS, and I'm not sure what version it is. Could you find out? On my linux box I can see by $ ldd /usr/lib/vlc/plugins/access/libaccess_srt_plugin.so
...
libsrt.so.1.4 => /usr/lib/libsrt.so.1.4 (0x00007f8624715000)

Test on windows with VLC 3.0.16 and got the same log " WARN srt_tokio::pending_connection > UnsupportedProtocolVersion(4) " |
|
@russelltg Hi russelltg, Is it possible that srt-rs support ProtocolVersion(4) ? :) |
|
Ceetainally not a high up feature on my list. You're welcome to implement it if you want, but in general compatibility with very old srt versions is not a huge priority. It seems that hsv5 was introduced in srt 1.3, which has been out for some 4 years now..... Your best bet is recompiling VLC with a newer version, or convert the srt stream to a local Udp one with srt-live-transmit from the reference implementation or srt-transmit from srt-rs. |
|
Closing for now. |
|
VLC 3.0.16 is already the newest version ... |
|
Yes but VLC internally uses Haivision's srt implementation to support playing srt streams. Whoever builds VLC integrates a very old version. |
|
After downloading the newest VLC binary for windows instead of building from source code, I got the same issue. |
|
After looking a bit more, only VLC 4.x bundles a new enough libsrt: Try the 4.x dev binaries here https://nightlies.videolan.org/ |

Going to reopen this as it seems like it may be a useful feature at some point. |
yes，the 4.x binary for windows works without issue |
