Jerky video with 2 blu-ray players
I'm experiencing that my blu-ray video created with tsMuxer gives a jerky picture on a very few players: A Cambridge azur 650BD and a Medion player.
20 other players that I have tested on plays my videos fine. I'm not certain whether I'm doing something wrong, or whether these single two players just have a problem with burned discs. They are videos recorded by cellphones and edited with Kdenlive. Then I extract audio using ffmpeg -i video.mp4 -acodec pcm_s24le audio.wav Then I convert video using two terminals. In terminal one: mplayer -vo yuv4mpeg:file=stream.y4m -nosound video.mp4 In terminal two: x264 stream.y4m –crf 22 –preset slow –tune film –weightp 0 –nal-hrd vbr –vbv-maxrate 40000 –vbv-bufsize 30000 –aud –keyint 24 –bframes 3 –slices 4 –level 4.1 –b-pyramid strict -o blurayvideo.mp4 Now I have audio.wav and blurayvideo.mp4 ready for tsMuxer. I using the following meta file for tsMuxer: MUXOPT --no-pcr-on-video-pid --blu-ray --vbr --mplsOffset=00000 --m2tsOffset=00000 --auto-chapters=5 --vbv-len=500 V_MPEG4/ISO/AVC, blurayvideo.mp4, fps=29.970, forceSEI, contSPS, track=1, lang=eng A_LPCM, audio.wav, lang=dan Generally I'm following this guide: https://irishjesus.wordpress.com/201...ring-in-linux/ When spotting the jerky picture with those two players, I looked at my above commands and noticed that I'm using -keyint 24 while fps is 29,970. I thought maybe this is the cause? I'm using 29,970 as fps because the videos are 30 fps, but I noticed there are a few players that don't like 30 fps videos, while all I've tested on seems to like 29,97 fps. But I can't set keyint to 29,97 since is has to be an integer.... Can anyone spot anything I'm doing wrong here? Thanks! |

Stick exactly to everything explained here (read carefully):

Thanks a lot sneaker.
That was a lot more than I had hoped for (and A LOT faster too). One slightly confusing thing though: As far as I can see, the tables tell me that 1080p30fps is not possible. Closest alternative is 1080i29.97. In other words, I can't have progressive 1080 at 29.97 fps? But one of the links at the bottom points to a 1080p29.97 example, where some parameter called -fake-interlaced is used. http://www.x264bluray.com/home/1080i-p Is this really still somehow valid blu-ray standard? Or should I go with the 1080i29.97 fps? Thanks a lot for your time. |
