ffmpeg transcodifica H264 entrelazado y sigue entrelazando a través del códec H264_NVENC
Iván Kolesnikov
Tengo el siguiente archivo H264 entrelazado:
Transmisión #0:0[0x335]: Video: h264 (Principal) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg, arriba primero), 720x576 [SAR 16:11 DAR 20 :11], 25 fps, 50 tbr, 90k tbn, 50 tbc
Y este es un cuadro del video fuente:
Cuando uso:
ffprobe -show_frames -i fuente.mpg | grep marco_entrelazado
Todos los fotogramas están entrelazados:
entrelazado_fotograma=1
entrelazado_fotograma=1
.
.
.
fotograma_entrelazado=1
Quiero transcodificar este archivo y seguir entrelazando e intentar hacerlo con el siguiente comando:
ffmpeg -i source.mpg -vcodec h264_nvenc -flags +ildct+ilme -acodec copy -f mpegts out.mpg
después de transcodificar el mismo cuadro del archivo "out.mpg" se ve como sigue:
Esta es una salida de la consola:

¿Cómo corregir la transcodificación del archivo H264 a H264 y seguir entrelazando a través del códec h264_nvenc?

Es un problema con los nuevos controladores de video. Todo está bien con el controlador de video 361.28 e inferior. Ya envié este problema al soporte de NVIDIA con el número de referencia 161118-000164
ACTUALIZACIÓN: este problema se resolvió desde el controlador 375.39 .
Permite seguir entrelazando en tarjetas de video Pascal 10x.

El video convertido por FFMPEG tiene una duración diferente, ¿por qué?
