Package: firefox Version: 124.0.1-1 Severity: important Dear Maintainer,
* What led up to the situation? Last week's dist-upgrade, including ffmpeg and libavcodec and related libs. * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? Observed that ALL video playback (with HTML5 tech) ceased to work, either no video starting at all or some error report, depending on the page. YT can generate a debug report, I could add it but there is not much to see, the main info is: "debug_error": "{\"errorCode\":\"html5.missingapi\",\"errorMessage\":\"This video format is not supported.\",\"SN\":\"HTML5_NO_AVAILABLE_FORMATS_FALLBACK\",\"yn\":\"\",\"wK\":\"nocodecs.1;a6s.0\" - next experiment: try firefox-esr. Result: no problem there, videos do work as usual - next experiment: download the upstream build and unpack it. Result: works as supposed. Also tried the 125-beta, also works there - next experiments: reinstall ffmpeg, reinstall libavcodec60, also tried libavcode-extra60, restarting firefox inbetween. Does not cure the problem, remains broken. - next experiment: did a strace on firefox, checking for libav... and yes, it loads the latest versions of that libs. And remains broken. - next experiment: double-checking the ArchLinux guide, https://wiki.archlinux.org/title/Firefox section 4.2.3. Tried setting and unsetting (to defaults) of those variables, and restarting. Did not change a thing, remains broken. Also tried removing the profile and starting with fresh settings, and even that remains broken (unlike with upstream build or ESR version in the same situation). - more digging: tried to observe error output. It prints something to STDERR but that isn't helpful. vainfo... lines are the same as from players like vlc, the other errors: no idea, maybe this is the culprit? - more digging: tried to generate debug output, like: MOZ_LOG_FILE=/tmp/upstream_log MOZ_LOG="FFmpegVideo:5" ./firefox That works just fine, those files (with ...child-number... extension) are created and in the one for the playback window, I can find lots of sensible codec log printing. BUT: when I do the same with our version, that also creates log files but they have zero size, nothing is even printed into them. So, is this maybe some internal failure in our build, which aborts the video engine loading early on without telling the user? * What outcome did you expect instead? A non-broken Debian package, at least SOME useful MOZ_LOG information in case when someone tries to debug issues. strace: 112061 openat(AT_FDCWD, "/usr/lib/firefox/libavcodec.so.60", O_RDONLY|O_CLOEXEC <unfinished ...> 112061 sendmsg(22, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/usr/lib/firefox/libavcodec.so.6"..., iov_len=34}, {iov_base=NULL, iov_len=0}], msg_iovlen=3, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[21]}], msg_controllen=24, msg_flags=0}, MSG_NOSIGNAL <unfinished ...> 112064 <... recvmsg resumed>{msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/usr/lib/firefox/libavcodec.so.6"..., iov_len=8194}], msg_iovlen=2, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[112]}], msg_controllen=24, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 50 112064 openat(AT_FDCWD, "/usr/lib/firefox/libavcodec.so.60", O_RDONLY|O_NOCTTY|O_CLOEXEC <unfinished ...> 112061 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libavcodec.so.60", O_RDONLY|O_CLOEXEC <unfinished ...> 112061 sendmsg(22, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/lib/x86_64-linux-gnu/libavcodec"..., iov_len=39}, {iov_base=NULL, iov_len=0}], msg_iovlen=3, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[21]}], msg_controllen=24, msg_flags=0}, MSG_NOSIGNAL <unfinished ...> 112064 <... recvmsg resumed>{msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/lib/x86_64-linux-gnu/libavcodec"..., iov_len=8194}], msg_iovlen=2, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[112]}], msg_controllen=24, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 55 112064 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libavcodec.so.60", O_RDONLY|O_NOCTTY|O_CLOEXEC <unfinished ...> 112061 openat(AT_FDCWD, "/usr/lib/firefox/libavutil.so.58", O_RDONLY|O_CLOEXEC <unfinished ...> 112061 sendmsg(22, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/usr/lib/firefox/libavutil.so.58"..., iov_len=33}, {iov_base=NULL, iov_len=0}], msg_iovlen=3, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[21]}], msg_controllen=24, msg_flags=0}, MSG_NOSIGNAL <unfinished ...> 112064 <... recvmsg resumed>{msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/usr/lib/firefox/libavutil.so.58"..., iov_len=8194}], msg_iovlen=2, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[116]}], msg_controllen=24, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 49 112064 openat(AT_FDCWD, "/usr/lib/firefox/libavutil.so.58", O_RDONLY|O_NOCTTY|O_CLOEXEC <unfinished ...> 112061 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libavutil.so.58", O_RDONLY|O_CLOEXEC <unfinished ...> 112061 sendmsg(22, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/lib/x86_64-linux-gnu/libavutil."..., iov_len=38}, {iov_base=NULL, iov_len=0}], msg_iovlen=3, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[21]}], msg_controllen=24, msg_flags=0}, MSG_NOSIGNAL <unfinished ...> 112064 <... recvmsg resumed>{msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\0\0\0\0\0\0\10\0\0\0\0\0\0\0\0\0", iov_len=16}, {iov_base="/lib/x86_64-linux-gnu/libavutil."..., iov_len=8194}], msg_iovlen=2, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[90]}], msg_controllen=24, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 54 112064 openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libavutil.so.58", O_RDONLY|O_NOCTTY|O_CLOEXEC <unfinished ...> STDERR: Fresh profile, no changes: [Child 95675, MediaDecoderStateMachine #1] WARNING: Decoder=7fe598245f00 state=DECODING_METADATA Decode metadata failed, shutting down decoder: file ./dom/media/MediaDecoderStateMachine.cpp:372 [Child 95675, MediaDecoderStateMachine #1] WARNING: Decoder=7fe598245f00 Decode error: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006) -
