Grabo un video desde mi Iphone y obtengo archivos .MOV usando vcodec hevc. Tal como está, no se puede reproducir ni utilizar en el software de edición.
Entonces intenté convertirlo a un archivo .mp4 usando el comando ffmpeg:
ffmpeg -i input.MOV output.mp4
Pero outpul.mp4 aún no se puede reproducir (no hay video, solo canción).
También intenté usar -vcodecla opción con h264vcodec pero el resultado es el mismo.
ffmpeg -i input.MOV -vcodec h264 output.mp4
Con otra opción (mismo problema):
ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4
Salida del comando:
me@my_pc:~/Test_vid$ ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4

Teniendo en cuenta un códec de vídeo no compatible (HVEC es compatible), es necesario volver a codificar el códec de vídeo:
ffmpeg -i input.mov -c:v libx264 -c:a copy output.mp4
El códec de audio debe filtrarse con:
-bsf:a aac_adtstoasc
Si quieres recortarlo (o simplemente hacerlo gráficamente), me gustaría proponerte miVideoCorteque se puede importar como ppa:
https://launchpad.net/~jentiger-moratai/+archive/ubuntu/mediatools
Para instalar es necesario ejecutar:
sudo add-apt-repository ppa:jentiger-moratai/mediatools
sudo apt update
sudo apt install --no-install-recommends install videocut
Actualizar
Al probarlo con mi aplicación VideoCut, se reduce a:
ffmpeg -i input.mov -c:v copy -c:a copy -bsf:a aac_adtstoasc -avoid_negative_ts 1 -shortest input2.mp4
Esta es la forma más rápida en que lo hace ffmpeg muxer. Al copiar los paquetes, se utiliza un filtro de audio para eliminar incompatibilidades del códec de audio en los contenedores respectivos (mov vs mp4). Los últimos 2 interruptores se utilizan para sincronización de audio.
Como se mencionó anteriormente, VideoCut hace esto automáticamente. El uso del muxer "remux" incorporado manejará los primeros fotogramas potencialmente faltantes (cosa que ffmeg no hace)
