Description

Summary of the bug:
I use the dvblast to generate UDP streams for the input of ffmpeg. When the ffmpeg starts to transcode, it is very stable and normal. But, I don't know what exactly time the video become cross green lines on the video. It can't no longer return to normal.

How to reproduce:
I don't know how can reproduce this. When I restart the ffmpeg process, it returns to normal.

But, I upload the input file(generated by dvblast, recorded by vlc) and the output file(HLS format, generated by ffmpeg via the below command) to the ftp. In addition, a complete console output also on the ftp(about 283MB).

And, the input file and the output file is not the same program segment, but they are also in the period in problem in the case.

I have uploaded files to the ftp server.

input: 1403781705_input_small.ts
output: 0800200c9a66.m3u8, 0800200c9a66[24-47].ts
complete console output: 1403781705_complete_Output_Log.log

The command:

/home/andy/ffmpeg -re -f mpegts -i udp://127.0.0.1:50000 -c:v libx264 -preset slow -deinterlace -crf 23 -pix_fmt yuv420p -g 150 -acodec libfdk_aac -b:a 128k -ac 2 -ar 44100 -loglevel debug -threads 0 -hls_time 5 -hls_wrap 100 -hls_list_size 24 -f hls /mnt/video/7/0800200c9a66.m3u8

The console output(segment, due to complete console output about 259MB):

  • Keywords green benetian blinds removed

How can I reproduce this?
I mean if I download the source file you uploaded how do I get the broken output?

comment:2 Changed 4 years ago by herman602

Sorry,
In my observation, it happens in random.
I have no accurate steps to reproduce this now.

comment:3 Changed 4 years ago by cehoyos

Does it also happen with file input? Or only with udp input?
Does it also happen if you use a native encoder like mpeg2video? Or only with x264?

comment:4 Changed 4 years ago by herman602

I can't use dvblast to regenerate that UDP stream,
so I use VLC to stream the input file which I uploaded.

After I tested it, the result is

file input + x264, OK
file input + mpeg2video, OK
udp input + x264, OK
udp input + mpeg2video, OK

But at the problem time, I use the VLC player to watch the video which generated by dvblast is normal. It's strange.

comment:5 Changed 4 years ago by cehoyos

So are you reporting a dvblast problem?

comment:6 Changed 4 years ago by herman602

Sorry, it's not.
At that time time, I killed that ffmpeg process, and I restarted the ffmpeg,
the video output become normal. And, I use the VLC player to watch the video stream generated by dvblast is normal, but after the ffmpeg transcoding process, the output is broken.
