From H264/VP8/VP9 to Audio and Video

ffmpeg -i {INPUT_FILE} -f s16le -ac 1 -ar {BITRATE} {OUTPUT_AUDIO_FILE} -f rawvideo -r {FRAMERATE} -pix_fmt yuv420p -vf scale={SCALING}:-1 {OUTPUT_VIDEO_FILE}

ffmpeg -i "$(youtube-dl -x -g "{YOUTUBE_LINK}")" -f s16le -ac 1 -ar {BITRATE} {OUTPUT_AUDIO_FILE} -f rawvideo -r {FRAMERATE} -pix_fmt yuv420p -vf scale={SCALING}:-1 {OUTPUT_VIDEO_FILE}

From YouTube Live stream to Video

Important!

The max resolution allowed by Telegram is of 720p at 30 fps Here also listed the scaling format

• 360p = 640
• 480p = 854
• 720p = 1280

If you have any problem with green screen or un-synchronized video, it can be one of these problems:

• Invalid FFMPEG command
• The video quality specified to convert is higher than the original video one
• Invalid PyTgCalls video parameters
• If you're using fifo, the Fifo max buffer size is too low and this cause the lag problem.
