Playback issues with compiled ffmpeg and libx264

0

I compiled libx264 in 10 bit mode and compiled ffmpeg against it. On windows BTW. It seems when I encode a video with my ffmpeg, my Windows Media Player with ffdshow codec is unable to play the video. I used the default x264 colorspace "yuv420p10le". Ffdshow reports output colorspace as "P010" when playing it and I can't get a video output. Other 10bit videos do play well with Ffdshow reporting the output colorspace as "YV12". I used the following parameters for libx264: CC=cl ./configure --disable-cli --enable-static --host=mingw64 --bit-depth=10 and the following parameters for ffmpeg: ./configure --toolchain=msvc --arch=x86 --extra-ldflags="-LIBPATH:/d/ffmpeg/lib" --extra-cflags="-I/d/ffmpeg/headers" --enable-yasm --enable-asm --enable-static --disable-shared --enable-gpl --enable-version3 --enable-libx264

I used the following command to convert: ffmpeg -i Input.mkv -vcodec h264 -an -sn Output.mkv

This is my ffmpeg output:

Is there some option I need to add while performing the conversion or during the build phase?

Use ffmpeg for encoding instead of x264. – Ipor Sircer – 2017-01-08T22:48:18.733

1@IporSircer - the OP is using ffmpeg to encode. To the OP, show the command you used. – Gyan – 2017-01-09T05:02:38.070

I used the following command: ffmpeg -i Input.mkv -vcodec h264 -an -sn Out.mkv – Trinopoty – 2017-01-09T07:03:05.553

Looks ok. YV12 is YUV 4:2:0 8-bit. Confirm those other videos are actually 10-bit. Try playback with VLC or Potplayer. – Gyan – 2017-01-09T07:33:12.133

VLC is able to play my video just fine. Also, VLC does report my other videos as "Planar YUV 4:2:0 10bit LE". I'm guessing ffdshow is doing something weird with them and converting to 8bit? If so, it should be able to do the same with my videos but it does not. PS: My converted videos also report "Planar YUV 4:2:0 10bit LE" in VLC. – Trinopoty – 2017-01-09T07:54:23.993

I'm not entirely sure of the problem but, I modified ffdshow configuration a bit and now I'm able to get a video output. I disabled P010 and ffdshow now outputs YV12. – Trinopoty – 2017-01-09T09:13:49.687
