Doom9's Forum - View Single Post - Importing interlaced AVC video into AviSynth running under Wine

Greetings,

I have been doing some research lately that I would like to confirm with others. I have been successfully using AviSynth with Wine to encode various sources (DVD, Blu-ray) with XviD and x264. A few days ago I got hold of a DVB-T tuner and it turns out that DVB-T transmissions in my country are encoded using AVC and broadcasted in 576i (TFF) and 1080i (MBAFF). I wasn't yet able to find any solution for importing interlaced AVC footage into AviSynth running under Wine. These are my findings so far:

- DGAVCDec has problems with interlaced AVC as it uses an ancient version of libavcodec. My captures processed by DGAVCIndex and then displayed in VirtualDub are full of macroblocks which make them unusable.

- FFmpegSource is able to index the *.TS files, but when I open the AviSynth source in VirtualDub, I either get a message saying "Insanity detected: decoder returned an empty frame" or a distorted first frame, followed by a crash during seeking.

- DGAVCDecNV requires a modern Nvidia GPU, which I don't have, plus it still wouldn't have worked as DGAVCDecNV relies on CUDA which doesn't work with Wine.

- DGAVCDecDi doesn't work with Wine (or at least I'm not able to run the registration application).

- DirectShowSource() doesn't work with Wine.

Is all the above correct? Is there any other solution I can use for proper handling of interlaced AVC in AviSynth running on Linux?
