ffmpeg -i /tmp/myfile.mp4 -y -ss 00:00:01 -t 00:00:01.000 /tmp/myfilesplit.1.mpg

Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
Как я могу устранить ошибку [mpeg1video @ 0x19cf4a0] MPEG1/2 does not support 15/1 fps
? Добавлять пустые P-кадры как-нибудь или подобное? Я пытаюсь добиться этого, используя любой ввод, поэтому я ищу универсальный способ программирования в моем php-скрипте.
