@hexa:lossy.network@hexa:lossy.network

Multiprotocol will remain an experimental feature and is not recommended for use.

22:21:48
@hexa:lossy.network@hexa:lossy.networkyes22:21:53
@hexa:lossy.network@hexa:lossy.network* no, the stream test22:22:00
@robert:funklause.dedotlambdaDo we have any idea in which Python module the segfault occurs?22:24:30
@hexa:lossy.network@hexa:lossy.networkI would assume pyav22:24:49
@robert:funklause.dedotlambdaActually, the HA tests seem to use x265 directly22:25:24
@hexa:lossy.network@hexa:lossy.networkoh22:25:33
@hexa:lossy.network@hexa:lossy.networkyeah, but that uses pyav22:26:37
@hexa:lossy.network@hexa:lossy.network 
    container = av.open(output, mode="w", format=container_format)

    stream = container.add_stream(encoder, rate=fps)
22:26:53
@hexa:lossy.network@hexa:lossy.network * 
    container = av.open(output, mode="w", format=container_format) # pyav here

    stream = container.add_stream(encoder, rate=fps) # "libx265" here
22:27:17
@robert:funklause.dedotlambda The broken test is test_h265_video_is_hvc1 22:27:53
@hexa:lossy.network@hexa:lossy.networkyep22:27:59
@hexa:lossy.network@hexa:lossy.networkI mean, ideally we can reproduce that outside the build sandbox22:32:36
@hexa:lossy.network@hexa:lossy.networkand get debugsymbols and can file an issue22:32:46
@robert:funklause.dedotlambdaIsn't it more likely to be a PyAV issue?22:33:05
@hexa:lossy.network@hexa:lossy.networkhttps://github.com/home-assistant/buildroot/blob/master/package/x265/x265.mk#L722:45:04
@hexa:lossy.network@hexa:lossy.networkwe use the same pyav version they pin22:45:19
@hexa:lossy.network@hexa:lossy.networkbut they are still on the old x265 version22:45:27
@hexa:lossy.network@hexa:lossy.networktheir ci runs on ubuntu-24.0422:46:03
@hexa:lossy.network@hexa:lossy.networkwhich also ships x265 3.522:46:20
