Я сгенерировал два файла MP4 - пятисекундный вступительный файл, который создается с помощью приведенного ниже сценария, а основное видео (длиной около одной минуты) создается с помощью метода screen-cast-omatic, оба в формате MP4. Когда я пытаюсь объединить их, используя ffmpeg -f concat -i mylist.txt -c copy outputметод, он создает выходной файл, в котором вступительный файл воспроизводится нормально. Затем воспроизводится основное видео; звук в порядке, но видео испорчено там, где сверху отображается искаженное видео.
Используя ffmpeg -i "concat:input1.mpg|input2.mpg|input3.mpg" -c copy output.mpgметод, на выходе получается видео, которое не является полным. Я не включил никакой вывод сценария на этом.
Некоторые могут проверить это и предложить рекомендацию?
Ниже приведен сценарий и приведен первый метод concat:

Я попытался использовать memcoderдля объединения двух видео, и у меня возникла проблема. Я подозреваю, что это связано с кодеком или скоростью fps / bit и т. Д., Так что я настроил скрипт на 10 fps для обоих видео, и вот memcodersрезультат:
