https://openharmony.gitee.com/openharmony/docs/issues/I1UU62?from=project-issue 这里的回答看看能不能帮到你

我用的是archlinux, 进入到vendor/hisi/hi35xx/middleware/source/third_party/ffmpeg/ffmpeg-y

vendor/hisi/hi35xx/middleware/source/third_party/ffmpeg 使用的是三方软件自身的automake，这里在configure的时候会自动根据环境打开一些配置，比如vdpau, 而这些依赖在编译harmonyos的时候是没有的。

我的临时建议是显示的关掉这个自动侦测的选项，参考修改在这里

https://gitee.com/openharmony/vendor_hisi_hi35xx_middleware_source_third_party_ffmpeg/commit/b48b9575ae01f3bd9b79a0d65f50d68668234285

最终的方案我会同步一个issue给ffmpeg的owner

#I1UX83:ffmpeg 在部分环境上编译失败

disable_decoder_config.sh这样改编译通过:

-- a/disable_decoder_config.sh
+++ b/disable_decoder_config.sh
@@ -47,6 +47,8 @@ configure_attr=" --prefix=./install \

这两个只在host安装不应该影响交叉编译吧, configure要指定host吧.

@kabirz 非常好
是这个configure问题，我们会先请ffmpeg同学清理一下自动侦测的config，后续考虑移植到GN编译。

@Xingwa

Please make sure the below problem also will be resolved while GN compilation reconsideration period.

Note :
valgrind-3.13.0 version available in system but still issue is reported. Thanks in advance.

@Dayananda V
Could you also try to add --disable-valgrind-backtrace in the disable_decoder_config.sh

Currently the confiure script detect some feautre from host but no avalivable on target platfrom. It is common issue.

@Xingwa

adding --disable-valgrind-backtrace in disable_decoder_config.sh doesn't help still same issue reproducing, any way am excluded valgrind dependency by commented and build success by following code change in libavutil/log.c

old code:

#if HAVE_VALGRIND_VALGRIND_H
#include <valgrind/valgrind.h>
/* this is the log level at which valgrind will output a full backtrace */
#define BACKTRACE_LOGLEVEL AV_LOG_ERROR
#endif

new code:

#if HAVE_VALGRIND_VALGRIND_H
//#include <valgrind/valgrind.h>
/* this is the log level at which valgrind will output a full backtrace */
//#define BACKTRACE_LOGLEVEL AV_LOG_ERROR
#endif

I have assigned this issue to ffmpeg folks.

--disable-valgrind-backtrace this doesn't resolve my problem

关闭了自动检测的编译配置项。
