ffmpeg transcoding stop after few seconds

9 avril 2018, par Salem F

Hi 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 tried

  ffmpeg  -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 enable AVOptionVideo crf setting on ffserver.conf trans-coding runs bit smoothly without frame-rate dropping .
Las my server uses Xeon L5520 CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core ) :(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 :-

how to use gl-transition in ffmpeg ?

19 avril 2020, par Zedd

I tried to use gl-transition with the following method.





https://github.com/transitive-bullshit/ffmpeg-gl-transition





But I followed the instructions many times without success.
I think it may be that this library is no longer maintained





Is there any other way to use gl-transition in the form of ffmpeg filter ?

streaming data with ffmpeg using pipe - stream never starts

9 novembre 2022, par tamirg

Im fetching some video data, and trying to stream it using ffmpeg. what i do is create an ffmpeg process, set it to get info from '-', and then when i fetch the video data i write it to the process STDIN.

My issue is that the steaming procces sometimes starts, and sometimes doesnt start. it really seems random (will add the ffmpeg logs at the end).
But if i save the entire data into a file, and then use ffplay on that file, it works perfectly fine, all the time.

So im guessing something in the data is causing some issues with ffmpeg usage with pipe. The logs indicate that there are some issues with the DTS, but i dont know if thats the reason that stream never plays, and what can be done to fix that.

I cant really understand the issue from the logs, but maybe they indicate what is the issue exactly ?

logs :

When the stream proccess doesnt start and doesnt work, those are the logs :

The main issue, is that it sometimes works, sometimes doesnt work.

The ffmpeg proccess is just created by using asyncio.create_subprocess_exec

Every time i get a video data, i pass the data to the proccess by calling ffmpeg_process.stdin.write(data)

I believe the issue is with the data, since with video data, the whole pipeline works for me. But i cannot understand from the ffmpeg logs what is the issue exactly.
