ffmpeg with MPEG to TY+ encoding support

[MarcPow]

For fun/educational purposes, I'm porting TivoServer to .NET/C#. I can use any standard FFMPEG to convert to MPG (no matter how they change it in the future), but I'm interested in trying to learn how to do a direct streaming MPG->TY conversion if possible. I'm a video neophyte; do you suggest that I look at your patch here for instruction, or can you suggest any additional resources?

Because file upload doesn't seem to be working for me, I've placed this in the following public SkyDrive folder:

http://cid-d6d3d991b85bad7b.skydrive...e.aspx/.Public

Because it's built against MSys and statically linked, it requires no additional supporting binaries of any kind. Just the executable, and you're home free.

Updated the ty-ffmpeg patch for ffmpeg 0.6, which brings faster (native) AAC (and now HE-AAC) decoding, faster H.264 decoding, and various bugfixes. See the release notes. For those coming from pre-0.5 versions, AC3 has also been native for a while.

Thanks to bcc & nova1 for their hard work, and DancingChicken for the previous patch. (Yes, this ffmpeg works with his WinTivoServer.)

1. wget http://www.ffmpeg.org/releases/ffmpeg-0.6.tar.gz
2. tar xzvf ffmpeg-0.6.tar.gz
3. cd ffmpeg-0.6
4. patch -p1 < ffmpeg0.6-ty1.9.patch.txt
5. ./configure --enable-gpl --enable-static --disable-shared --enable-memalign-hack --enable-avfilter --enable-avfilter-lavf --enable-w32threads --enable-avisynth
6. make

Those last two configure flags are obviously Windows-specific. For Linux multi-threading, use --enable-pthreads instead.

Tested on the latest MinGW GCC 4.5. I used the automated installer (mingw-get-inst-2010909) with C++, MSYS Basic, and MinGW Developer Toolkit checked and it compiled cleanly.

I haven't tried it in Linux yet, report any issues.

Uploaded the Windows binaries to Megaupload since they were too big for the forum. As previously mentioned, compiled in MinGW (no support DLLs required) with multithreading support (i.e.: tyffmpeg -threads 2 -i "video.avi" -vcodec mpeg2video -b 3000k -acodec mp2 -ab 192k "video.ty").

Does anyone have the latest build of this? I don't have a windows build environment set up. Seems like ac3 decoding is broke:

I downloaded MinGW and ffmpeg 0.6 with 1.9 patch built fine. It seems to do a better job than the older version I was using, less sync issues. I have a Series 1 DirecTiVo I still use, and any mpeg I used so far seems to work, with maybe some minor stuttering, more so with ac3 audio. I have a Series 1 Standalone that plays converted files fine, except it has to be mp2, there is no built in ac3 decoder. In trying some DVDs, I tried one but ffmpeg gives me an error once it reaches 2GB and won't continue on. The error has to do with lseek, I'll post it when I run it again. It's as if ffmpeg is trying to write 2GB is the limit, so it doesn't work well for a full DVD. Anyone else have this issue?

Has anybody ported this to 0.7 yet?

Can someone point me to a more up-to-date version, or help fix the error, THANKS

[mikey]

use the most up to date ffmpeg you can to make a compatible .mpg. Use the ty enabled ffmpeg in the second post to convert to .ty. Works every time. perfect sync.

I had the Linux version of ty enabled ffmpeg running on a Mac years ago but there must have been some library files or something I've lost along the way. I get a "cannot execute binary file" error.

I'm placing this message here in case anybody runs across it someday who knows how to run ty enabled ffmpeg on a Mac.

Looking for windows binary for ffmpeg to convert avi to ty. Please help all the above links are dead. Try the build in post 2 but has I/O error says file is corrtupt, does not matter what file i try.
