Hello, how are you friends?
my Internet provider also offers me television (rtp), I have used
ffmpeg to capture a documentary with a duration of one hour,
transmitted atraves of one of these channels.
I have tried to preserve the codec of video and the quality, have
tried to select the audio codec like mp3, I have tried to eliminate
the audio track that was not of interest and have tried to eliminate
the subtitles track to reduce the size of the file, nevertheless I
obtain multiple bugs that I believe they are related to the audio, I
have realized the input of the following departure:

>ffmpeg -i imput1.ts -vcodec libxvid -b:v 2282 -acodec mp3 -ac 0 -sn output1.avi
