FFMPEG 有时会在视频末尾添加黑帧

FFMPEG 有时会在视频末尾添加黑帧

我正在通过 ffmpeg 运行一些视频,以生成 mp4、webm 和 ogg 文件以供 HTML5 播放器播放。

视频旨在循环播放,但有时 ffmpeg 会在末尾添加黑帧 - 导致循环播放时闪烁。

作为转换的一部分,我将帧速率更改为 24fps - 我猜测问题就出在其中。

我的 bash 脚本(重要部分):

#!/bin/bash
# $1 = input file
# $2 = output file name
# $3 = bitrate (in k)

# Variables
BITRATE=${3-1000}
BUFSIZE=$(($BITRATE * 2))
OGGBITRATE=$(($BITRATE * 100 / 85))
OGGBUFSIZE=$(($OGGBITRATE * 2))

echo "1. mp4 @ 720p - first pass"
ffmpeg \
-i $1 \
-vf scale=-1:720 \
-y \
-r 24 \
-an \
-vcodec h264 \
-preset veryslow \
-b:v "$BITRATE"k \
-maxrate "$BITRATE"k \
-bufsize "$BUFSIZE"k \
-pass 1 \
-f mp4 /dev/null

echo "1. mp4 @ 720p - second pass"
ffmpeg \
-i $1 \
-vf scale=-1:720 \
-y \
-r 24 \
-an \
-vcodec h264 \
-preset veryslow \
-b:v "$BITRATE"k \
-maxrate "$BITRATE"k \
-bufsize "$BUFSIZE"k \
-pass 2 \
-f mp4 \
"$DIST"/files/"$2".mp4[/code]
