Initialisation de MediaSPIP (préconfiguration)

FFmpeg HLS input stream shows "Packet corrupt" and "timestamp discontinuity" errors when pushing to RTMP server [closed]
22 mai, par Amul BhatiaI'm trying to restream an HLS URL (https://cache.fastcdn.com.my/edge/53-1.stream/index_0.m3u8?misc=87uq4HjbDEDE3TzIY95ja1ZMxA-Cm1PbOXAk16riVlU&uid=139322&ts=1747931206&e=43200&lat=1747931206&sil=5&sk=no&uip=MTEwLjIyNC4yNDIuOTg&head=aHR0cF94X2ZvcndhcmRlZF9mb3I&chid=53-1') into my RTMP server with FFmpeg.

However, I get repeated errors like :


Packet corrupt (stream = 0, dts = xxxx)


timestamp discontinuity (stream id=0)


corrupt input packet in stream 0


The stream partially works but seems unstable. How can I fix this error ?


my nginx.conf


rtmp {

 hls on;

The same url is working fine when used in browser, but extracting the stream and putting it in RTMP server and accessing my RTMP server at rtmp ://69.62.85.241/live/streamkey not working

12 ffmpeg xfade transitions : "option not found"
17 juillet 2023, par nimdaI'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :


- 

- hlwind
- hrwind
- vuwind
- vdwind
- coverleft
- coverright
- coverup
- coverdown
- revealleft
- revealright
- revealup
- revealdown


























I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :


ffmpeg -f lavfi -t 169
