h264: invalid 8x8 inference, reference decoder works fine

[wanderman]

ffplay.exe cann't play the h.264.ts file, but the old version is OK!

Attached h264 raw stream can be decoded with the reference decoder, ffmpeg does not decode the stream since 1c3ce2cd3ef3df47eccb0245017a6d2f3d5308b4 (r21668), protesting "This stream was generated by a broken encoder, invalid 8x8 inference"

thanks! this file can do be played, but now my another H264 TS file (1080P) can not be played, before it can be played smoothly.

[wanderman]

I have already uploaded this file to  http://upload.ffmpeg.org/upload/. this file name is H264-TS-CanNotBePlayedSmoothly1080P-zw2.ts .

[wanderman]

divided to less size to upload

The problem you reported was fixed in N-33660 (2ed7e353bd8867215bc156c430d4ded7f6774ad4). I just tested N-33659 (1d0afec8fcfaca9736c927715ddd56a5902855ab), N-33660 and current git head (N-33691, 55d44578c61ccd8b7db50e26e01196476ea530f3), and all three decode H264-TS-CanNotBePlayedSmoothly1080P-zw3.ts bit-identically, so I assume any problems you have with this file are not related to the original report.

Please open a new ticket, explain what is wrong when decoding H264-TS-CanNotBePlayedSmoothly1080P-zw3.ts (re-encoding works fine for me with current ffmpeg) and please do not forget to add the command line you are using and complete, uncut console output (only report ffplay problems if they are unreproducible with ffmpeg and please mention this clearly if you report a ffplay problem).
