Tvheadend

Dunno about OpenSuse, but 'buntu needs libavcodec-extra-53 or similar, which includes libx264 as the encoding library. There's also libx264-dev, which I think may include the same.

So I managed to solve the problem with h264. U need to use specific ffmpeg release. In my case i used 1.2.5, the latest GIT of ffmpeg doesn't work, because it's libavcodec is higher then 55.0.0. So you need something between 52.49 and 55.0.0.0 as is requested. Unfortunately now the problem switched from h264 to AAC and i'm in same problem just with AAC. Which was working before...

2014-01-29 09:47:25.520 transcode: Unable to open libfdk_aac encoder

version of:

ffmpeg 1.2.5

libavutil 52. 18.100 / 52. 18.100

fdk-aac 0.1.3

tvheadend latest git 3.9~

So I made success that transcoding is working with this versions:

tvheadend: version 3.9.379~g6f1b17e-dirty
libav - 0.8.9
libavcodec 53.35.0
libavutil 51.22.1
libavformat 53.21.1
libswscale 2.1.0

with
faac

all other combinations: ffmpeg 1.2.5, ffmpeg 2.0.3, ffmpeg-latest-git, libav 9.10, fdk_aac

are not working and will not find aac encoder even it was compiled and it is in system (in ffmpeg 1.2.5 and libav 9.10 fdk_aac)
or
it will not find h264 coder even it was compiled and it is working (ffmpeg 2.0.3, ffmpeg-latest)

So it's working. But the quality of sound is horrible, it's breaking, clicky etc...

I built with a new~ish copy of ffmpeg I updated the transcode.c to use ffmpeg audio4 calls and fixed some other depreciated buffer stuff.
Packages:
openssl 1.0.1
zlib 1.2.3.4
libcurl 7.22.0
liburiparser 0.7.5
avahi-client 0.6.30
libavcodec 55.45.103
libavutil 52.58.101
libavformat 55.22.100
libswscale 2.5.101

Can anyone decipher what -22 is ? from ffmpeg avcodec_decode_video2 and avcodec_decode_audio4 these are on the decode side not the encode side.

I have plex plug-in calling and it seems so close ....

Sorry, i has firware updated the hdhomerun but not fixed the libraries to match, now I have decodes , and a mux problem that i can persue.

The failed to write frame is were it's at, possibly due to AVFrame type changes that I made for audio4 support, I'll keep looking
