cdg format: cannot find suitable combination for converting to video, tried .mp4, .mkv, .mpg filenames
Hi All, I'm trying to convert a cdg (MP3CDG/Karaoke file) into any sort of more compatible video format, the idea is to mux it then with audio and use a normal video player to play karaoke.
By the way I'm having difficulties to adapt a given example to obtain any kind of most common video format (mkv, mp4, ...) and it seems I cannot match the right combination of options to get something, all I got since now are empty output files or files that are really little and doesn't play.
I'm using ubuntu 23.10, I installed ffmpeg using ubuntu deb and ffpyplayer in a virtual environment using poetry
ffmpeg -i output
$ ffmpeg -i songs/***.cdg

Input #0, cdg, from 'songs/*******.cdg':
Duration: 00:06:41.11, start: 0.000000, bitrate: 57 kb/s
Stream #0:0: Video: cdgraphics, pal8, 300x216, 300 fps, 300 tbr, 300 tbn
from here I took pix_fmt_in option
ffprobe output for frame rate:
ffprobe -v 0 -of compact=p=0 -select_streams 0 -show_entries stream=r_frame_rate songs/***.cdg
r_frame_rate=300/1***.mp3
so it should be 300, 1
python code
In here I tried to detect the right codec iterating each one available on my system, but I didn't find anything valid, In this example you can see mkv file extension as output, but I also tried with no luck also with mp4 and mpg:
import time

import ffmpeg
import bawx_player
from ffpyplayer.player import MediaPlayer
from ffpyplayer.writer import MediaWriter
def kar2video(cdg_file, mp3_file, video_file):

video_file: the name of the resulting file
"""
# only video
ff_opts = {'an': True, 'sync': 'video'}
player = MediaPlayer(cdg_file, ff_opts=ff_opts)
# wait for size to be initialized (todo: add timeout and check for quitting)
while player.get_metadata()['src_vid_size'] == (0, 0):
time.sleep(0.01)
frame_size = player.get_metadata()['src_vid_size']
print(frame_size[0], frame_size[1])
# use the same size as the inputs
codec = 'zmbv'
list_of_codecs = ffpyplayer.tools.get_codecs(encode=True, video=True)
for codec in list_of_codecs:
try:
out_opts = {'pix_fmt_in': 'pal8', 'width_in': frame_size[0],
'height_in': frame_size[1], 'codec': codec,
'frame_rate': (300, 1)
}
writer = MediaWriter(video_file, [out_opts], overwrite=True)
while 1:
frame, val = player.get_frame()
if val == 'eof':
break
elif frame is None:
time.sleep(0.01)
else:
img, t = frame
writer.write_frame(img=img, pts=t, stream=0)
