ffmpeg transcoding stop after few seconds
9 avril 2018, par Salem FHi i’m trying to do this over week now with no success ,
What’s i’m trying to do is transcoding video from live streaming source and downscale it with FFmpeg , but every time I start transcoding it broadcasting fro 11 Sec and stop . here last command I triedffmpeg -re -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffm
I tried to download the .ts file with IDM and it finish downloading the file on the exact 12 Sec that FFmpeg stop trans coding on it .
does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually . BTW I tried with source with VLC player and it didn’t stop playing the the same source video .
Edit :- I decide to pass FFmpeg command via FFserver config file
ffserver.conf
Launch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copy
The stream works fine for a while but after testing couple sources I notice it’s struggle to trans-coding HD videos .
I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only ) ! Since I tried using
ultrafast
preset but din’t solve the issue , another thing , I notice when I enableAVOptionVideo crf
setting onffserver.conf
trans-coding runs bit smoothly without frame-rate dropping .
Las my server usesXeon L5520
CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core ) :(Edit 2 :-

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
worse




What is wrong in my code ? Thanks in advance
