[HOW-TO] h264 Timestamp File for mkv Conversion

See original GitHub issue

I’m trying to convert the .h264 output files from this library to .mkv for playback. Is there any way to save a timestamp file like you can with the libcamera --save-pts option?

At the moment this isn’t possible. @chrisruk what do you think?

As an alternative/workaround you could do this:

from picamera2 import Picamera2
from picamera2.encoders import H264Encoder
from picamera2.outputs import FfmpegOutput

picam2 = Picamera2()
picam2.configure(picam2.video_configuration())
encoder = H264Encoder(bitrate=10000000)
output = FfmpegOutput('test.mkv')
picam2.start_recording(encoder, output)

though the timestamps in the file won’t be as accurate.

@ccostes Hi, would it be useful for you if we added # timestamp format v2 as the first line of the timestamp file (like the --save-pts option does for libcamera-vid) so you can import it straight into mkvmerge? If so I can add that feature
