improved Transcoding (e.g. Raspberry)
0%
Description
I'm running TVheadend successfull on my PI2 and im quiet happy with the home-network Streaming. Now i wanna go a step further and like to stream my channels online - ofc i need a transcoding bc of ultraSlow DSL upload speed.
And i wish we could customize the transcoding (like setting custom encoders and arguments and so on)
The problem right now is that the builtIn de/encoder dont have hardware suport....rasperry cpu cant even handle SD.
There ARE transcoders like gstreamer or omxtx that using RPI hardware coders. U can even transcode HD material smoothly with them.
Im just not good in programming and i would need like 10years to understand and implement that feature in TVH. But i guess many people would be happy about that.

We use ffmpeg for transcoding, so it would be better to ask there....

thanks for your answer.
btw. VP8 is the only codec working but with 5-10sec lags
is ffmpeg not supported at raspberry? in stream profile as type i can choose transcode/av-lib (no word about ffmpeg), and there is no setting working for me. e.g.:
videocodec: libx264

so i guess i did something wrong at install? but i couldnt remember an option to install ffmpeg, or is there a trick do get ffmpeg included after i installed tvheadend? or just no support for PI?
