Convert 功能无效，仅生成一个 0KB 的 .mp4 文件
H1DDENADM1N opened this issue · comments
点击Convert后会生成一个 0KB 的 .mp4 文件，长时间等待无数据写入，观察到dash-player.exe CPU和内存占用无波动。再次点击Concert，转换进度条直接100%。继续点击Convert，进度条仍会直接100%。示例如下图：
DashPlayer软件版本：4.2.0
系统版本：Windows11 24H2 26120.670
示例视频：TheFallGuy.mkv The.Fall.Guy.2024.2160p.ITunes.WEB-DL.H265.HDR.DDP5.1.Atmos-MOMOWEB[1LOU.ME].torrent
补充说明：路径和文件名无中文或特殊字符。有测试其他mkv电影，同样无法转换。
我这两天修复了一些转换失败的情况，下一版您看看会不会成功。
好的，一会我试试你发的视频。
我参考源码注释尝试调用ffmpeg命令行 ffmpeg -i input.mp4 -c:v libx264 -c:a aac output.mp4
报错如下：

}你着急的话先试试这个呢？
我使用了AI修正的命令 ffmpeg.exe -i ."vid.mkv" -map 0 -map -0:s -c copy -c:a ac3 "vid.mkv" 测试可用，但是用DashPlayer播放无声音，用PotPlayer有声音。
好的谢谢，没有声音可能是因为Chrome不支持对应的音频编码，还要在命令里加入转换音频编码的部分
使用了 ffmpeg.exe -i ."vid.mkv" -map 0 -map -0:s -c copy -c:a aac "vid.mkv" 转换为aac音频编码可以播放声音。
根据AI的解析：FFmpeg在尝试写入MP4文件时遇到了一个问题：它无法为字幕流找到正确的编码标签。MP4容器不支持SUBRIP字幕格式，这可能是导致Convert 功能无效，仅生成一个 0KB 的 .mp4 文件的原因。
只是，这个命令去掉了所有的字幕流着实浪费，想要只排除SUBRIP字幕流而不是所有字幕流又会有点麻烦。辛苦大佬继续优化了。
另，希望DashPlayer可以有更多运行异常提示。
你着急的话先试试这个呢？
我试了下这个 ffmpeg -i "vid.mkv" -map 0 -c copy -c:a aac "MP4/vid.mp4" ，同样会报错：
