Os pacotes não estão na ordem correta com relação ao DTS ao usar libx264 para vídeo

3

Estou tentando usar o seguinte comando para transcodificar um fluxo em um formato diferente e enviá-lo para o servidor RTMP para transmissão ao vivo.

Este é o comando que estou usando:

ffmpeg -f mxg -i http://admin:[email protected]:80/control/faststream.jpg?stream=MxPEG -strict -2 -c:v libx264 -c:a aac -ar 44100 -ac 1 -f flv -s 1024x768 rtmp://localhost:1340/big/test

Aparentemente, ele decodifica alguns quadros e acaba com um erro:

O que está errado aqui, como eu supero isso?
