dvb stream hd transcoding, Buffer queue overflow, dropping

[stefki]

I am trying to transcode Dvb stream and overlay dvb subtitle but I am getting a lot of errors and frames drops. The video gets green noise and freezes a lot.

this is my command line

nohup ./ffmpeg -i "udp://lo@224.1.1.1:1235?fifo_size=256000&buffer_size=2097152&overrun_nonfatal=1" -copytb 1 -filter_complex "[0:v][0:s:0]overlay[v];[v]scale=1280:720[y]" -map [y] -map 0:1 -b:v 2000k -maxrate 2500k -bufsize 4000k -c:v libx264 -strict 2 -profile:v "baseline" -preset veryfast -g 50 -keyint_min 50 -acodec aac -ac 2 -ar 44100 -ab 128k -vsync 1 -async 1 -f mpegts udp://224.0.0.12:1123?pkt_size=1316 2> /home/chhd.log &

I am using latest git version, also I tried with latest stable ffmpeg version, but I am facing the same problem

Please record the input stream (not with FFmpeg) and provide the sample input file and command line together with complete, uncut console output.

Is the issue only reproducible with network output or also with file output?
Please provide a command line that allows to reproduce your issue with the input file you provided together with the complete, uncut console output.

[stefki]

I tested the video file now, the problem is on file output and network output also.

any help ??

Is there a problem with transport stream or command line ?

Maybe someone of the developers may suggest something.

Replying to stefki:

I tested the video file now, the problem is on file output and network output also.

What is wrong with the output file test.ts?

Unrelated: Please understand that security issues were found in the past for FFmpeg, using a root account for transcoding is not a good idea.

[stefki]

I converted the file now again and the output file test.ts is converted ok . No frames lost.

Strange ?? what can be ?
