timecodes

I have a simply formatted text file (Edit Decision List) with rows of numbers (timecode frame rate 25) followed by rows of properties (names etc.). Ultimately I am trying to: retrieve the lines starting with * FROM CLIP NAME: and the row/line (timecode) immediately above. On this line are Timecodes, there are 4 groups of numbers, each are expressed as 00:00:00:00 - or HH:MM:SS:FF or Hours, minutes, seconds, frames. Then I discard everything else. Use the first 2 number groups (they are start and end times) to derive duration . Then append duration to the Clip Name line. Save file as

Since we are unable to get Closed caption data or subtitle data out of the AVPlayer, we are looking at other trigger methods, such as timecode or at least the knowledge of the .ts file that is currently active. I couldn't find anything in the documentation and the CMTime from the player doesn't give me the timecode that is embedded in the m3u8 files. NSLog(@"%f", CMTimeGetSeconds([mPlayer currentTime] ) ); is not what I'm looking for. #EXTM3U #EXT-X-TARGETDURATION:10 #EXT-X-MEDIA-SEQUENCE:562 #EXT-X-PROGRAM-DATE-TIME:2020-10-23T14:18:59+08:00 #EXTINF:10, http://aedsgios1-i.akamaihd.net/hls

I got a question regarding calculating time code delta. I read metadata from a movie file containing a timecode formated HH:MM:SS:FF ( FF = frame, 00->23 for example. So its like 00 to framerate-1 ) So i get some data like 15:41:08:02 and from another refrence file i get 15:41:07:00 Now I have to calculate the timeoffset (like timedelta but just with frames). How would i go around doing this? framerate = 24 def timecode_to_frames(timecode): return sum(f * int(t) for f,t in zip((3600*framerate, 60*framerate, framerate, 1), timecode.split(':'))) print timecode_to_frames('15:41:08:02') - timecode

I have researched the subject for some time now and still haven't figure it out. I use midas3 library (Midi-actionscript3) to import midi to flash. I get each note-item on a timeline. I get the divisions value (192) and all of the "GET-TEMPO" elements are equal to 81. I tried a lot of combinations to get the actual time of the midi but still no good (timeline*192/60 for example). The reason I know it is not synchronized to the actual time is that when I visualize the notes as simple rectangles in flash - I check if they appear exactly to what the mp3 file plays (I have converted the midi file
