FFMPEG“分段错误"被称为“分段错误".与网络流源 [英] FFMPEG "Segmentation fault" with network stream source
问题描述
我使用的发行版:4.2.2(静态)来自" https://johnvansickle.com/ffmpeg/"
I use release: 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"
最终代码将显示在"Amazon AWS lambda"上
Final code will be on "Amazon AWS lambda"
目标:使用网址流并添加watermak
Goal: use a url stream and add watermak
链接到视频: https://feoval.fr/519.mp4
链接到Watermak: https://feoval.fr/watermark.png
Link to Watermak: https://feoval.fr/watermark.png
./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4
返回细分错误"
我的计算机和AWS Lambda服务器上都存在相同的错误
I have the same error on my computer and on AWS Lambda server
./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4
工作(但不行watermak)
work (but not watermak)
./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4
工作(但不支持流)
非常感谢您！

推荐答案
与johnvansickle.com的内部版本打包在一起的 readme.txt 一样:
According to readme.txt that is packaged with the build from johnvansickle.com:
静态链接glibc的局限性在于DNS的丢失解析度.通过软件包管理器安装nscd可以修复这个.
A limitation of statically linking glibc is the loss of DNS resolution. Installing nscd through your package manager will fix this.
解决方案是安装并启动nscd服务.
替代解决方案:
- 编译您自己的ffmpeg(在
./configure期间启用gnutls，openssl，libtls或mbedtls以支持HTTPS). - 在您的存储库中使用ffmpeg
- 下载输入文件，然后在ffmpeg中使用它
- 使用IP地址代替域名
- Compile your own ffmpeg (during
./configureenable gnutls, openssl, libtls or mbedtls for HTTPS support). - Use ffmpeg from your repository
- Download the input file before using it in ffmpeg
- Use IP address instead of domain name
