Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

avutil/mem_internal : Don't include stdalign.h on MSVC
17 décembre 2024, par Martin Storsjöavutil/mem_internal : Don't include stdalign.h on MSVC
It's currently actually not used in MSVC builds, since
6e49b8699657b808b7dc80033f2c3f2d0e029fa3.Older versions of MSVC (or, in particular, older versions of UCRT)
don't have stdalign.h ; it's available since WinSDK 10.0.20348.0 ;
such a new enough version has been installed by default only since
MSVC 2022 17.4 and newer.With this change, ffmpeg can still be built with MSVC 2019 16.8
(v19.28).Signed-off-by : Martin Storsjö <martin@martin.st>

ffmpeg mp4 to hls transcode fails on Azure Windows Server Image [closed]
13 février, par James WeatherheadI am having an issue with transcoding an mp4 (any mp4) to hls. If I run the command below on my Windows 11 machine it works fine. If I run it on a clean Windows 11 VM, it works fine. If I run it on a clean Windows 2022 Server VM it works fine. If I create a Windows 2022 server image in Azure and run it... it fails (see error below)


I feel like something that FFMPEG needs is missing from the default server image in Azure. Has anyone experienced this issue and found a way to solve it ?


The command I am using :


ffmpeg.exe -i LowPriVMs-1.mp4 -filter_complex "[0:v]split=1[v1] ; [v1]scale=w=1920:h=1080[v1out] ; " -map "[v1out]" -c:v:0 mpeg4 -b:v:0 5000k -maxrate:v:0 5350k -bufsize:v:0 7500k -map a:0 -c:a aac -b:a:0 192k -ac 2 -f hls -hls_time 10 -hls_playlist_type vod -hls_flags independent_segments -hls_segment_type mpegts -hls_segment_filename stream_%v/data%03d.ts -master_pl_name master.m3u8 -var_stream_map "v:0,a:0" stream_%v/playlist.m3u8


The error returned by FFMPEG is :


[out#0/hls @ 00000204c6aded40] Could not write header (incorrect codec parameters ?) : Invalid argument


Has anyone else encountered this and found a solution ? I wondered if it is required to add a Feature Pack or some such dependency to Windows ?


Thanks
James
