Hello.
Converting movies to h264 some files is creating videos that beggins with whited frames.
I try converting the original to others formates to then generate h264, and the same problem occur.
Some idea ???

Yeah, this is the command line I use:
Code:ffmpeg -i origem/1910_1962/2007-05-21-infamous.mov -vcodec h264 -s 320x174 -b 400k -r 48 -acodec mp3 -ar 22050 -ab 56 med/2007-05-21-infamous.mov
Code:File: origem/1910_1962/2007-05-21-infamous.mov Width: 480 pixels Height: 260 pixels Aspect ratio: 1.33:1 Frames: 0 Duration: 00:02:21 hours/mins/secs Framerate: 24.000 frames per second Video format: avc1 Video bitrate: 0 bits per second --------------------------- Audio track 1 (Stream 0.0, AID 0): --------------------------- Codec: aac Bitrate: Stream #0.0(eng): Audio: aac, 44100 Hz, stereo000 bits per second Sampling rate: 44100 Hz ========================================================= Audio is compliant with the following formats: Not compliant with (S)VCD or DVD Video is compliant with the following formats: Not compliant with (S)VCD or DVD This video does not seem to be compliant with (S)VCD or DVD standards. If you burn it to a video disc, it may not work. =========================================================
This problem happens in the beggin of the video file, and audio is OK.
Ffmpeg outputs a set of this lines:
Code:[h264 @ 0x39318f50d0]OVERFLOW levelcode=4101

Thanks for helping -
Hi,
I've had similar issues encoding H.264 with ffmpeg, I finally traced it back to the quantizer settings. In your command line you have not specified a qmin or a qmax. H.264 or at least x264 which ffmpeg uses has a a range from -qmin 2 to -qmax 51. I found that increasing the qmin to a value of 10 stopped the overflows and retained excellent quality. Try adding -qmin 10 -qmax 51 to your command line and see if it helps. It eliminated the problem for me.My Site: http://www.bandshed.net/AVLinux.html
