String cmd1 = "ffmpeg -i \"concat:"+cmd+"\" -acodec copy -vcodec copy -absf aac_adtstoasc "+Environment.getExternalStorageDirectory().toString() +"/loveVideo/"+"00.ts"+"|"+Environment .getExternalStorageDirectory().toString() +"/loveVideo/"+"0000.mp4";

ffmpeg -i "Apache Sqoop Tutorial Part 1.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts ffmpeg -i "Apache Sqoop Tutorial Part 2.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts ffmpeg -i "Apache Sqoop Tutorial Part 3.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate3.ts ffmpeg -i "Apache Sqoop Tutorial Part 4.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate4.ts ffmpeg -i "concat:intermediate1.ts|intermediate2.ts|intermediate3.ts|intermediate4.ts" -c copy -bsf:a aac_adtstoasc "Apache Sqoop Tutorial.mp4" 这是拼接视频的命令 总是报c语言的错误

ffmpeg -i concat:/storage/emulated/0/videoparser/v1.ts|/storage/emulated/0/videoparser/VID_1499654806465.ts|/storage/emulated/0/videoparser/v2.ts|/storage/emulated/0/videoparser/VID_1499654816185.ts| -vcodec copy -acodec copy /storage/emulated/0/videoparser/1499654820477.ts

我也遇到了同样问题,mp4转ts没问题,拼接就崩溃 使用的是精简版,难道需要用完整版?

我是用的完整版 崩溃 /arm/libjx_ffmpeg_jni.so (setup_find_stream_info_opts+15) ng-1/lib/arm/libjx_ffmpeg_jni.so /libjx_ffmpeg_jni.so /libjx_ffmpeg_jni.so (ffmpeg_parse_options+174) ng-1/lib/arm/libjx_ffmpeg_jni.so (jxRun+366) ng-1/lib/arm/libjx_ffmpeg_jni.so (ffmpeg_cmd_run+20) ng-1/lib/arm/libjx_ffmpeg_jni.so (Java_com_mabeijianxi_smallvideorecord

那只能求解作者了@mabeijianxi 之前使用的是https://github.com/WritingMinds/ffmpeg-android-java这个拼接是正常的 但是太大了有20M+

kangjie6501 commented 7 years ago

https://github.com/WritingMinds/ffmpeg-android-java 我用命令怎么只能显示版本 不能生成想要的文件

wudifamo commented 7 years ago

cmd不要ffmepg开头 直接-i concat...

mabeijianxi commented 7 years ago

周末我看看

mabeijianxi commented 7 years ago

这个问题已经弄好了，我试了可以通过 concat 合并 ts 文件，我还没合并到主分支上，用 dev https://github.com/mabeijianxi/small-video-record/tree/dev 分支上的 so 试试

wudifamo commented 7 years ago

用demo试了下确实可以了,但是我把SmallVideoLib2导入我的demo再依赖还是会崩溃,应该是我这边的问题了,不知道和ndk { abiFilters "armeabi-v7a" }有没有关系

mabeijianxi commented 7 years ago

@wudifamo 兄弟你再试试呢，可能是上次我没提完整，试好了反馈下，没问题我就合并分支了，还是在 dev 分支上

wudifamo commented 7 years ago

@mabeijianxi 可以了
