Script d’installation automatique de MediaSPIP

Concatenating multiple mp4 files [duplicate]
18 octobre 2019, par Mr MedusaThis question already has an answer here :
I’m currently trying to join multiple mp4 video files into one file, and I found the ffmpeg library and looked at a lot of ways on how I should use it.
Currently I’m usingffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4
This should work, but for some reason it doesn’t. My terminal is filled with this
(Can’t give anymore output than this)
[mp4 @ 000002ce260bc180] Non-monotonous DTS in output stream 0:0; previous: 24541175, current: 5482875; changing to 24541176. This may result in incorrect timestamps in the output file.

At least one output file must be specifiedI’ve read most of the posts on here about ffmpeg causing this issue for other people, but none of the fixes that are explained have worked for me.
The video output I get seems fine for the first video, but then once it’s supposed to transition into the other videos it just "freezes" or sets the speed to something like 100x. Output video also ends up being 28 minutes long instead of 2.8 minutes.
Anyone able to help me ? -

FFMPEG NVENC HEVC to H264
18 octobre 2022, par SambirI try to transcode a HEVC 4k broadcast down to 1080p H264. HEVC 4K to HEVC 1080p works but when I try hevc to h264 i get "No NVENC capable devices found"



Now I am wondering is it not possible to fully hw transcode HEVC to H264 ?



Code used :



ffmpeg -timeout 10000000 -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -hwaccel_device 0 -hwaccel cuvid -vcodec hevc_cuvid -resize 1920x1080 -i 'http://inputstream' -max_muxing_queue_size 1024 -map 0:0 -map 0:2 -acodec libfdk_aac -b:a 96k -c:v h264_nvenc -gpu 0 -preset llhq -profile high -rc:v vbr -qmin:v 26 -qmax:v 32 -b:v 4M -maxrate 4M -bufsize 8M -threads 0 -r 25 -g 100 -f mpegts 'udp://127.0.0.1:6472' 




When I run the code :



[h264_nvenc @ 0x3bf42c0] Provided device doesn't support required NVENC features
Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed !



Is it not possible to convert HEVC back to H264 ?
