How to avoid data loss through network using gstreamer library

[Sérgio Agostinho]

Hey, 

Assuming you’re asking for a lossless video codec, according to here https://en.wikipedia.org/wiki/List_of_codecs#Lossless_compression_2 <https://en.wikipedia.org/wiki/List_of_codecs#Lossless_compression_2> , x264enc supports lossless compression. This page https://trac.ffmpeg.org/wiki/Encode/H.264#LosslessH.264 <https://trac.ffmpeg.org/wiki/Encode/H.264#LosslessH.264> mentions how to configure this. I would try to set the properties qp-min and qp-max to 0, the speed-preset to ultrafast and remove all other options on the element.

Cheers
