This is my first post here. I am in a situation where my original file is of profile High and transcoding profile is High10. I am suspecting that this is the cause my video is not getting played in jwplayer. I have also tried to set profile to -profile:v high but no help . I am using ffmpeg version

ffmpeg version 2.6.2

No pixel format specified, yuv420p10le for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
x264 [error]: high profile doesn't support a bit depth of 10
[libx264 @ 0x350d960] Error setting profile high.
[libx264 @ 0x350d960] Possible profiles: baseline main high high10 high422 high444

Please help me.

  • Like the error message says, use "-pix_fmt yuv420p" and place it after "-profile:v high"

  • maybe I need to compile and install ffmpeg than using a build. libx264 seems to be a problem, maybe does not have required codec

  • Can you post the entire command you used? And also the output of "ffprobe -i <yourinputfile>"

  • Here is the shortest command I am using to check if my "High" video is getting converted to "High" again ----- ffmpeg -i 50_Cent___My_Life_ft__Eminem__Adam_Levine_hd720.mp4 -profile:v high -pix_fmt yuv420p arvind34.mp4 . The original video downloaded from youtube is of "High " profile which after above command is converted to "High10". ffprobe gives segmentation fault on the input video

The ffmpeg build you have uses libx264 compiled for 10-bit. Apparently one can only build with support for either 8-bit OR 10-bit. So, you'll need a build where libx264 supports 8-bit.
