用FFMPEG级联YUV产生输出YUV

Question

我有10元的输入，每一个元是WxH的一个框架(ip0_WxH.yuv，ip1_WxH.yuv，.，ip9_WxH.yuv)

我需要将所有10帧连接起来，以创建一个包含所有10帧的最终yuv输出。

选项1:

我用下面的链接来做这件事。但是从第2帧开始，最终的yuv输出是不合适的。只有第一帧看起来不错。从第2帧开始，色度和luma的缓冲地址可能是一些错误的索引，因此图片的显示是错误的。

Converting more yuv frames to one yuv frame

cat *.yuv > movie.yuv

备选方案2:

我尝试使用FFMPEG将yuv连接在一起：https://trac.ffmpeg.org/wiki/Concatenate。

$ cat mylist.txt
file 'ip0_WxH.yuv'
file 'ip1_WxH.yuv'
file 'ip2_WxH.yuv'

Desktop/danny$ ffmpeg -f rawvideo -f concat -safe 0 -i myfile.txt -c out.yuv

但是得到了这个错误：

...
Trailing options were found on the commandline.
[IMGUTILS @ 0x7fff4d92d720] Picture size 0x0 is invalid
[concat @ 0x558b6c335900] Impossible to open 'ip0_WxH.yuv'
myfile.txt: Invalid argument

可以建议使用ffmpeg命令将这些YUVs连接在一起.。

更新：

根据llogan提出的第一个答案，我使用了以下命令：

ffmpeg -f image2 -c:v rawvideo -pixel_format rgb24 -video_size 1344x968 -i  ip%d_WxH.yuv output.yuv

输出

~/Desktop/danny$ ffmpeg -f image2 -c:v rawvideo -pixel_format rgb24 -video_size 1344x968 -i  ip%d_WxH.yuv output.yuv

Answer 1

尝试不同的Try格式。

就像你在使用yuv一样。因此，使用yuv422p或yuv420p取决于输入的yuv类型。

试试这个：

ffmpeg -f image2 -c:v rawvideo -pixel_format yuv420p -video_size 1344x968 -i ip%d_WxH.yuv out.yuv
