Unfortunately I don't have much experience with playing .h264
files directly, at least in MP4 the frame time comes from the container IIRC. There is a chance that your frame rate is just "randomly" set by your player in absence of any further frame timing information, but YMMV.
It seems that the default fps is set to approximately 30, but not exactly. I tried setting a specific frame count, but when I opened the resulting h264 file with a video player, the playtime was shorter than expected. I was expecting the video to be 1 hour long if the fps was 30, but the resulting h264 file with 108,000 frames had a playtime of only 59 minutes and 53 seconds.
I tried several options such as changing rate control mode, setting a maximum frame rate of 30.0, and disabling skip frames, but I still can't accurately predict the playtime of the resulting video. The missing seconds make it very difficult for me to sync the audio. Can I get some advice?
