It was still broken in Michael's git as of 2011-mar-16.
The test case is very simple: h264 in .ts transcoded to h264 in .ts.
During encode run, for "Output #0" ffmpeg prints:
Stream #0.0: Video: libx264, yuv420p, 720x480 [PAR 10:11 DAR
15:11], q=10-51, 200 kb/s, 90k tbn, 29.97 tbc
Yet, ffmpeg -i on the resulting file says:
Stream #0.0[0x100]: Video: h264 (High), yuv420p, 720x480 [PAR 10:11
DAR 15:11], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
Do the tbc look the same to you?
